A Faith-based Glossary for Climate-informed Congregations

Definition: Adaptation refers to the adjustments people, communities, and ecosystems make in response to actual or expected climate change. This can include building flood defenses, planting drought-resistant crops, or changing how buildings are cooled and heated. Adaptation emphasizes learning to live with changes that are already underway while reducing future harm. It is a companion to mitigation, which focuses on preventing climate change in the first place.

Why it matters for people of faith: Many faith traditions emphasize resilience, compassion, and care for the vulnerable, all of which are central to adaptation. Congregations are often on the front lines of providing support in disasters and can lead by example in preparing for climate impacts. Understanding adaptation allows people of faith to see how their communities can embody hope and preparedness. It also reinforces the moral call to protect those most at risk, such as the poor, elderly, and displaced.

Definition: Carbon capture refers to technologies and processes that remove carbon dioxide (CO₂) from the atmosphere or prevent it from entering the air in the first place. This can involve capturing emissions from power plants, industrial facilities, or directly from the air, then storing them underground or using them in products. While it cannot replace the need to reduce fossil fuel use, carbon capture can help lower emissions from sectors that are hard to decarbonize. The effectiveness and cost of these methods vary, and they remain a subject of debate among scientists and policymakers.

Why it matters for people of faith: Faith communities often balance idealism with pragmatism, seeking both immediate and long-term solutions to harm. Carbon capture represents just one tool among many to address the climate crisis, especially for protecting those already at risk from severe impacts. Understanding its possibilities and limitations allows congregations to make informed decisions when advocating for climate policy. It also reflects a broader ethical question: how do we repair damage we have already done to creation.

Definition: A carbon footprint measures the total amount of greenhouse gases—mainly carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O)—that are released directly or indirectly by an individual, organization, activity, or product. It includes emissions from energy use, transportation, food production, and manufacturing. Carbon footprints are often expressed in tons of CO₂ equivalent (CO₂e) per year, allowing comparisons across different activities. Reducing one’s footprint means lowering the environmental impact through cleaner energy, efficient practices, and sustainable choices.

\Why it matters for people of faith: Many faith traditions teach that human beings are caretakers of creation and accountable for how our actions affect others and the Earth. Understanding our carbon footprint helps communities connect everyday habits—like travel, diet, and energy use—to broader moral and ecological consequences. Measuring and reducing emissions becomes a spiritual practice of mindfulness and stewardship. For people of faith, shrinking a carbon footprint is one way to live out reverence, justice, and love for the whole web of life.

Definition: Climate advocacy refers to organized efforts to influence policies, institutions, and public opinion in support of solutions to climate change. It can take many forms, from lobbying elected officials to organizing community rallies, writing op-eds, or supporting renewable energy projects. Advocacy emphasizes the power of collective action to bring about systemic change rather than leaving the burden on individuals alone. It links personal conviction with public responsibility.

Why it matters for people of faith: Many religious traditions teach that faith must be lived out through action for justice, not only personal belief. Climate advocacy allows faith communities to raise their moral voice in the public square, amplifying the call for care of creation and protection of the vulnerable. Engaging in advocacy can also unite diverse congregations in shared work, bridging theological or political differences around a common cause. In doing so, advocacy becomes both a civic duty and a spiritual practice.

Definition: Climate change is the long-term alteration of Earth’s climate system, largely due to human activity such as burning fossil fuels, deforestation, and industrial agriculture. This leads to rising global temperatures, shifting weather patterns, melting ice, and more extreme events like floods, droughts, and hurricanes. Climate change is not a distant threat but a present reality that is reshaping ecosystems and societies worldwide. It also compounds existing inequalities, as marginalized groups are often most affected.

Why it matters for people of faith: Every major faith tradition affirms the goodness of creation and the moral duty to protect life. Climate change challenges these commitments by threatening biodiversity, livelihoods, and the stability of communities. For people of faith, it represents not just an environmental issue but a deeply spiritual, moral, and ethical crisis. Addressing it is a way of practicing stewardship, justice, and compassion across generations.

Definition: A climate denier is someone who rejects or dismisses the overwhelming scientific consensus that climate change is real, human-caused, and dangerous. Denial can take many forms, from outright disbelief to minimizing its severity or delaying meaningful action. Some deniers rely on misinformation or political ideology, while others may feel overwhelmed and resist acknowledging the problem. This resistance can hinder collective efforts to address the crisis effectively.

Why it matters for people of faith: Faith communities are called to seek truth and resist falsehood, especially when denial leads to harm. Understanding the dynamics of climate denial helps people of faith respond with patience, compassion, and honesty. Congregations can serve as spaces of dialogue, where misinformation is gently challenged, and hope-filled alternatives are offered. Naming and addressing denial also affirms the spiritual value of integrity and courage in the face of reality.

Definition: Climate migration refers to the movement of people forced or encouraged to leave their homes due to the effects of climate change, such as rising seas, drought, desertification, or severe storms. Unlike traditional migration driven by political or economic factors, climate migration stems from environmental disruption that undermines survival or livelihoods. The numbers of climate migrants are expected to rise dramatically in the coming decades as global warming intensifies. Some will move within their countries, while others will cross borders, often without clear legal protections.

Why it matters for people of faith: Migration has always been part of the human story and features prominently in sacred texts, from the Exodus to the Hijra to the diaspora experiences of countless peoples. Faith traditions call their followers to hospitality, compassion, and justice for the displaced. Understanding climate migration challenges faith communities to expand their moral concern to those displaced by environmental causes. It invites congregations to offer welcome, advocate for fair policy, and bear witness to the shared vulnerability of all creation.

Definition: Climate-informed Congregations integrate awareness of climate science, environmental justice, and ecological limits into the practices of preaching, teaching, worship, and community care. They recognize that climate change affects every area of human and planetary well-being, from food and health to mental and spiritual resilience. While there is no one way such a congregation looks, these faith communities go beyond treating environmental issues or efforts as “add-ons” to congregational programs, instead weaving them into the fabric of faith life. Climate-informed communities also consider how congregational operations and decisions reflect care for creation.

Why it matters for people of faith: Congregations that acknowledge the realities of the climate crisis helps the people in those faith communities to respond faithfully to today’s greatest moral and existential challenge. This approach equips clergy and lay leaders to address eco-anxiety, injustice, disasters, and congregational priorities through a lens of awareness, hope, compassion, and action. Across traditions, climate-informed congregations express the belief that spiritual care includes care for the Earth and all its inhabitants. They transform climate awareness into a prophetic vocation, a calling for everyone in a community of faith.

Definition: Climate justice is a framework that emphasizes the ethical, moral and social dimensions of climate change, recognizing that those least responsible for emissions often suffer the greatest consequences. It calls attention to the disproportionate impacts on low-income communities, Indigenous peoples, and nations of the Global South. Climate justice demands systemic changes to address inequality alongside environmental action. It reframes the crisis as a matter of equity and human rights, not only science.

Why it matters for people of faith: Justice is a core value across traditions, from the Hebrew prophets’ calls for righteousness, to the Qur’an’s teachings on equity, to the Buddhist emphasis on compassion. Climate justice echoes these commitments by centering the needs of the vulnerable and marginalized. For congregations, pursuing climate justice means aligning ecological concern with solidarity, reparative action, and advocacy. It transforms climate work from charity into an expression of moral obligation and love of neighbor.

Definition: Community solar refers to shared solar energy projects that allow multiple households, organizations, or congregations to benefit from a single solar array. Participants buy or subscribe to a portion of the project’s energy, which offsets their electricity bills. This model expands access to clean energy for renters, low-income families, and those without suitable rooftops for panels. Community solar strengthens local economies and energy resilience while reducing dependence on fossil fuels.

Why it matters for people of faith: Community solar embodies cooperation, justice, and shared benefit—values at the heart of many faith traditions. It allows congregations to participate in clean energy solutions even if they can’t install panels themselves. By supporting or hosting community solar projects, faith groups demonstrate stewardship and solidarity with their neighbors. This approach turns renewable energy into a collective act of faith and care for creation.

Definition: Carbon dioxide (CO₂) is a naturally occurring greenhouse gas that is essential for life in small amounts but harmful in excess. Human activities—especially burning coal, oil, and natural gas—have dramatically increased CO₂ levels in the atmosphere, leading to global warming and ocean acidification. While CO₂ is not the only greenhouse gas, it is the largest contributor to human-caused climate change. Understanding CO₂ levels is central to climate science and international agreements. Our planet’s stability depends upon us reducing CO₂ levels to 350 ppm (parts per million)–a threshold we crossed in 1986–from our current level of approximately 425 ppm.

Why it matters for people of faith: Recognizing CO₂ as both a life-giving and life-threatening substance reflects the complexity of creation itself. Faith communities can help translate scientific knowledge into moral urgency, making clear that excessive emissions endanger the balance of Earth’s systems. By understanding CO₂, congregations can advocate for reductions and model sustainable living. This knowledge equips people of faith to speak with clarity about humanity’s responsibility in the crisis.

Definition: Creation care is a theological term emphasizing humanity’s responsibility to protect and nurture the natural world. Rooted in the belief that the Earth belongs to God (or is itself sacred), creation care reframes environmental stewardship as a spiritual duty. Different traditions interpret it in distinct ways. For example, Christian theology often highlights stewardship, Indigenous traditions emphasize kinship with the land, and Hindu and Buddhist teachings stress interconnectedness. Creation care links spiritual practice with ecological responsibility.

Why it matters for people of faith: Framing ecological responsibility as creation care helps congregations connect environmental issues with their deepest values. It shifts the conversation from politics to spirituality, highlighting love, gratitude, and reverence for the Earth. Creation care offers common ground across diverse traditions, enabling interfaith cooperation. By embracing it, people of faith live out their calling to honor and protect the sacredness of life.

Definition: Divestment is the process of withdrawing investments from companies or industries that are deemed harmful, such as fossil fuel corporations, in order to align financial practices with ethical or environmental values. It is both a moral stance and a financial strategy, aiming to shift capital toward more sustainable and just alternatives. Divestment campaigns have been used historically to oppose apartheid, tobacco industries, and now the fossil fuel sector. The movement often works in tandem with advocacy for reinvestment in renewable energy and community-focused initiatives.

Why it matters for people of faith: Divestment allows congregations and faith-based institutions to match their financial decisions with their spiritual commitments. Many traditions emphasize avoiding complicity in harm and directing resources toward life-giving purposes. By divesting from industries driving climate change, faith communities bear witness to their values in a tangible way. This action can also inspire members and the wider public to consider the moral dimensions of their own investments.

Definition: Ecoanxiety (or eco-anxiety) is the sense of fear, grief, or helplessness that arises in response to climate change and environmental degradation. It can manifest as worry about the planet’s future, guilt over personal choices, or despair about systemic inaction. While not a clinical disorder, ecoanxiety is recognized by mental health professionals as a serious emotional response to the climate crisis. It is particularly common among younger generations who face an uncertain future.

Why it matters for people of faith: Faith communities have long provided spiritual and emotional care in times of fear and uncertainty. By acknowledging ecoanxiety, congregations can offer spaces of lament, prayer, and hope. Addressing it also allows faith groups to affirm that grief over creation’s suffering is a faithful response, not a weakness. Supporting those experiencing ecoanxiety demonstrates compassion and resilience rooted in trust, community, and hope for renewal.

Definition: Ecotheology is the study of the relationship between religion and the environment, exploring how theological ideas shape our view of creation. It challenges interpretations that see nature only as a resource for human use and instead emphasizes interconnectedness, stewardship, and reverence for life. Different traditions contribute unique insights—for example, Christianity often speaks of stewardship, Judaism of tikkun olam (repairing the world), and Indigenous traditions of sacred reciprocity. Ecotheology connects sacred texts and teachings with ecological realities.

Why it matters for people of faith: Ecotheology helps congregations ground climate action in deeply held beliefs, transforming it from a political choice into a spiritual commitment. It allows communities to reinterpret scripture and tradition in light of today’s crisis, discovering new depths of meaning. Engaging ecotheology also fosters interfaith dialogue, as different traditions share wisdom about living in harmony with the Earth. By embracing it, faith communities can articulate a hopeful, sacred vision for ecological justice.

Definition: Energy efficiency means using less energy to perform the same task, often through improved technology or better practices. Examples include LED lighting, well-insulated buildings, and efficient appliances. Energy efficiency reduces costs, lowers emissions, and conserves resources without requiring major lifestyle changes. It is often described as the “first fuel” (the fuel you need not use) because it can deliver immediate benefits while supporting larger sustainability goals.

Why it matters for people of faith: Many faith traditions emphasize avoiding waste and honoring the gifts of creation. Practicing energy efficiency aligns with these values by conserving resources and reducing harm to the environment. For congregations, energy efficiency can also free up financial resources that can be redirected toward mission and service. By modeling efficiency, faith communities witness to the possibility of responsible and joyful living.

Definition: Environmental ethics is the field of moral philosophy and theology that explores how humans should relate to the natural world. It asks questions about rights, responsibilities, and the moral worth of nonhuman life. Environmental ethics draws from multiple traditions, including Indigenous worldviews that see all beings as kin and religious teachings that affirm creation as sacred. It challenges anthropocentric thinking and encourages respect, restraint, and reciprocity in human behavior.

Why it matters for people of faith: Faith communities are moral teachers, shaping how people view their place in creation. Environmental ethics provides a framework for translating belief into action—connecting theology with daily choices and public advocacy. By exploring what their own traditions teach about humanity’s role in the web of life, faith groups can find both humility and inspiration. Grounding ecological action in ethics ensures that sustainability efforts are not just practical but deeply spiritual and moral.

Definition: Environmental stewardship is the careful and responsible management of Earth’s natural resources. In Christian traditions, this concept is often tied to the Genesis mandate to “till and keep” the garden, while in Islam it is expressed through khalifah (guardianship), and in many Indigenous traditions it is reflected in kinship with the land. Stewardship emphasizes both care and accountability, highlighting humanity’s role as caretakers rather than exploiters and requires thoughtful use of resources for the common good. It is both a moral and spiritual calling, bridging spiritual values with ecological responsibility.

Why it matters for people of faith: Stewardship is a common thread across many traditions, making it a powerful unifying language for interfaith collaboration. For Christians, it reflects the Genesis call to tend the garden; for Jews, the principle of tikkun olam (repairing the world); for Muslims, the concept of khalifa (guardianship). By embracing environmental stewardship, congregations can embody their sacred duty to protect creation for current and future generations. It transforms ecological responsibility into an act of worship, service, and justice. Practicing stewardship is one way people of faith live out their covenant with the Creator and creation alike, aligning their daily practices with their deepest values.

Definition: Feedback loops are processes within the Earth’s climate system where an initial change triggers effects that either amplify (positive feedback) or reduce (negative feedback) that change. For example, melting ice reduces the planet’s reflectivity, causing more heat absorption and further melting—a positive feedback. Other loops, such as increased plant growth absorbing more CO₂, can have stabilizing effects. Understanding feedback loops is crucial for predicting how fast and severely climate change may progress.

Why it matters for people of faith: Feedback loops remind us of the deep interconnection within creation—how actions in one part of the system reverberate throughout the whole. Many faith traditions teach that human choices have cascading moral and ecological consequences. Recognizing feedback loops underscores the urgency of timely action before damage becomes self-reinforcing. For people of faith, this knowledge deepens reverence for creation’s balance and responsibility for protecting it.

Definition: Fossil fuels—coal, oil, and natural gas—are energy sources formed over millions of years from the remains of ancient plants and animals. Burning them has powered industrial growth but is also the leading cause of greenhouse gas emissions. Fossil fuels are finite, and their extraction and use cause widespread harm, from air pollution to habitat destruction to climate change. Alternatives such as renewable energy are increasingly viable and necessary.

Why it matters for people of faith: Continuing reliance on fossil fuels threatens the health of people, ecosystems, and future generations, raising moral questions of justice and responsibility. Many faith communities are choosing to divest from fossil fuels as a witness to their values. Understanding the impact of fossil fuels helps congregations connect everyday energy choices with their ethical commitments. This awareness underscores the urgent need to transition to more life-giving sources of energy.

Definition: Geothermal energy is renewable energy harnessed from the natural heat within the Earth. It can be used to generate electricity or directly heat buildings and water. Because it provides consistent, low-emission energy, geothermal is a reliable alternative to fossil fuels. Its use depends on local geography, as geothermal resources are more accessible in some regions than others.

Why it matters for people of faith: Geothermal energy reflects the abundance of renewable resources already present in creation. For congregations, supporting or investing in geothermal projects demonstrates care for the Earth while promoting sustainability. Faith traditions often teach that the Earth provides enough for our needs if we live wisely; geothermal energy embodies this principle by offering clean, steady power. Embracing it helps communities model faithful stewardship and long-term thinking.

Definition: A gift economy is a system in which goods and services are given without explicit expectation of payment, relying instead on reciprocity, trust, and relationship. Unlike market economies driven by profit, gift economies emphasize generosity, gratitude, and mutual care. They have been practiced in many Indigenous and communal traditions throughout history and continue today in various forms. Such systems value people and relationships over financial gain.

Why it matters for people of faith: Many religious traditions celebrate generosity, almsgiving, and mutual support as sacred practices. Gift economies resonate with these values, offering an alternative to consumerism and extractive systems. For faith communities, practicing forms of gift economy—such as sharing resources, community gardens, or mutual aid—embodies trust in divine abundance. It affirms that life is sustained not by endless consumption but by care, gratitude, and solidarity.

Definition: The greenhouse effect is the natural process by which certain gases in Earth’s atmosphere—like carbon dioxide, methane, and water vapor—trap heat from the sun. This process keeps the planet warm enough to sustain life. However, human activities have increased greenhouse gas concentrations, intensifying the effect and leading to global warming. Without intervention, this enhanced greenhouse effect disrupts ecosystems, weather patterns, and human societies.

Why it matters for people of faith: Understanding the greenhouse effect helps faith communities connect scientific knowledge with moral responsibility. It illustrates how human choices affect creation in profound ways. By learning about this process, congregations can better explain and address climate change within their spiritual and ethical frameworks. It reinforces the teaching that human beings must live in balance with creation, respecting natural limits.

Definition: A Green Team is a group within a congregation dedicated to promoting environmental awareness and action. Members often lead projects such as energy audits, recycling programs, educational events, and advocacy campaigns. Green Teams can also connect congregations with wider interfaith or community-based environmental initiatives. They serve as hubs of leadership, inspiration, and accountability for sustainable living. Individual congregations may use their own related terms, such as Creation Care Committee or Sustainability Servants.

Why it matters for people of faith: Green Teams embody the principle that caring for creation is a shared responsibility, not an individual burden. They empower congregations to move from talk to action, turning faith into practical steps for sustainability. Many traditions affirm that communal action is more powerful than solitary effort, and Green Teams reflect this wisdom. They also provide a visible, public witness of a community’s commitment to justice, stewardship, and hope.

Definition: Greenwashing is the practice of making false or exaggerated claims about the environmental benefits of a product, policy, or organization. Companies or institutions may use greenwashing to appear eco-friendly while continuing harmful practices. This misleads consumers and undermines genuine sustainability efforts. Greenwashing can occur through advertising, selective reporting, or symbolic gestures that do not result in meaningful change.

Why it matters for people of faith: Truth-telling is a core value across spiritual traditions, and greenwashing represents a distortion of truth for profit. Faith communities need to be discerning when evaluating environmental claims, ensuring their support aligns with authentic practices. By naming and rejecting greenwashing, congregations bear witness to integrity and justice. This discernment also protects communities from complicity in harm disguised as care.

Definition: Heat pumps are energy-efficient systems that move heat rather than generate it, providing both heating and cooling. In winter, they draw heat from the air, ground, or water into buildings; in summer, they reverse the process to provide cooling. Because they use electricity instead of burning fossil fuels, they produce fewer emissions and lower energy costs over time. Modern heat pumps can function effectively even in cold climates, making them a versatile option for many regions.

Why it matters for people of faith: Heat pumps provide a practical way for congregations and households to reduce reliance on fossil fuels. Investing in such technologies can embody stewardship by lowering carbon footprints while also saving money for ministry and mission. They represent a hopeful example of how innovation can align with care for creation. By adopting them, faith communities show that sustainable living is possible and accessible.

Definition: Hydrology is the scientific study of water, including its movement, distribution, and quality. It examines how water interacts with ecosystems, human systems, and the atmosphere. Understanding hydrology is crucial for managing floods, droughts, and the sustainability of freshwater supplies. It also connects directly to climate change, which is altering precipitation patterns and water cycles worldwide.

Why it matters for people of faith: Many faith traditions view water as sacred—used in rituals like baptism, ablution, or purification. Understanding hydrology deepens respect for water as both a spiritual symbol and a life-sustaining resource. It equips congregations to respond faithfully to water-related crises, from drought relief to flood recovery. Protecting water honors creation and safeguards justice for communities most affected by scarcity or pollution.

Definition: The Inflation Reduction Act of 2022 is the largest U.S. federal investment in climate and clean energy initiatives. It provides funding, tax credits, and incentives for renewable energy, electric vehicles, efficiency upgrades, and climate resilience projects. The act also emphasizes environmental justice by directing resources to communities disproportionately affected by pollution. While primarily economic legislation, its climate impacts are significant.

Why it matters for people of faith: The IRA offers faith communities opportunities to access funding for energy improvements in their facilities, reducing costs and emissions. It demonstrates how public policy can be a tool for protecting creation and promoting justice. By engaging with the IRA, congregations can model civic responsibility and ethical use of resources. Understanding it helps people of faith see how advocacy and policy change translate into tangible creation care. Several critical aspects of the IRA have been attacked or defunded by the current administration, which harms individuals, congregations, and nonprofits by redirecting money that could instead be used for their work of helping others.

Definition: Interfaith collaboration refers to cooperative efforts between people of different religious traditions to pursue shared goals. In the context of climate, it often involves joint advocacy, education, and projects that protect the environment. Such collaborations highlight shared values—such as justice, stewardship, and compassion—while respecting theological differences. Interfaith initiatives amplify impact by bringing diverse voices and communities together.

Why it matters for people of faith: Climate change is a global issue that transcends individual traditions, making interfaith collaboration both necessary and powerful. Working together demonstrates that care for creation is a moral concern rooted in many spiritual worldviews. It also builds bridges of understanding, respect, and peace between communities. For faith groups, interfaith collaboration reflects unity in diversity and strengthens witness in the public square.

Definition: Mitigation refers to actions that reduce or prevent greenhouse gas emissions to limit the extent of climate change. Strategies include transitioning to renewable energy, improving efficiency, reforestation, and adopting sustainable agriculture. Mitigation addresses the causes of climate change, complementing adaptation measures that address its impacts. It is a long-term commitment requiring global cooperation, innovation, and persistence.

Why it matters for people of faith: Mitigation reflects the moral call to prevent harm rather than merely respond after it occurs. For faith communities, it embodies stewardship and foresight, ensuring that future generations inherit a livable planet. It also affirms that human choices matter, offering a hopeful message that damage can be lessened through collective action. Participating in mitigation efforts helps congregations live faithfully and responsibly in a warming world.

Definition: Net zero describes the balance between greenhouse gases emitted into the atmosphere and those removed or offset. Achieving net zero often involves reducing emissions as much as possible and then compensating for the remainder through carbon capture, reforestation, or other methods. Many nations, organizations, and faith groups have set net-zero targets for mid-century. It represents a pathway toward stabilizing the climate and preventing the most catastrophic impacts.

Why it matters for people of faith: Net zero embodies the principle of accountability, ensuring that communities take responsibility for the pollution they generate. It challenges faith groups to model integrity by reducing their own emissions while advocating for systemic change. Striving for net zero can inspire hope by demonstrating that a different future is possible. It reminds people of faith that balance and harmony are core values across many traditions.

Definition: Nonrenewable resources are natural resources—such as coal, oil, and natural gas—that do not replenish quickly enough to be considered sustainable. Once depleted, they are gone for human timescales. Their extraction and use often cause significant environmental harm, including habitat destruction and pollution. Reliance on nonrenewable resources is a central driver of climate change.

Why it matters for people of faith: The depletion of nonrenewable resources highlights the danger of short-term gain over long-term care, a lesson echoed in many sacred traditions. For congregations, reducing reliance on these resources embodies faithfulness to principles of sustainability and justice. It underscores the need to live within limits and to prioritize renewable, life-giving alternatives. By teaching about nonrenewables, faith communities can help shape wiser choices for the future.

Definition: Nuclear energy is produced by splitting atoms in a process called fission, which generates heat used to produce electricity. It emits very low greenhouse gases compared to fossil fuels, but it raises concerns about radioactive waste, safety, and costs. Proponents argue that it provides reliable, large-scale clean energy; critics highlight risks and unresolved waste storage challenges. It remains one of the most debated energy sources in climate discussions.

Why it matters for people of faith: Nuclear energy raises profound ethical questions about risk, responsibility, and intergenerational justice. Faith communities can contribute moral discernment to the debate, weighing human needs for energy against long-term safety and stewardship concerns. Understanding nuclear energy helps congregations engage thoughtfully in policy and community discussions. It affirms that creation care requires both scientific understanding and ethical reflection.

Definition: Nudging refers to strategies that subtly encourage people to make choices that are better for themselves or society without restricting freedom. In the climate context, nudges might include defaulting thermostats to efficient settings, labeling carbon footprints on menus, or making recycling bins more prominent than trash bins. Nudges rely on behavioral science to promote sustainable habits. While small individually, they can add up to significant impacts.

Why it matters for people of faith: Many religious traditions encourage daily practices that shape character over time—prayer, fasting, generosity. Nudges work in a similar way, helping people form sustainable habits that align with values of care and justice. Congregations can use nudges in their own spaces, making sustainable choices easier and more visible. By doing so, they help members live out ecological responsibility in tangible, everyday ways.

Definition: Carbon offsets are investments in projects that reduce or remove greenhouse gases, such as reforestation or renewable energy, used to compensate for emissions elsewhere. They are often purchased by individuals, businesses, or organizations seeking to balance out their carbon footprint. While they can play a role in climate solutions, critics argue they may delay the deeper systemic changes needed to cut emissions at the source. Effective offsets require transparency, accountability, and real environmental benefit.

Why it matters for people of faith: Offsets raise questions about accountability and integrity—are we truly reducing harm, or paying for the appearance of action? Faith communities can model discernment by using offsets only when paired with serious efforts to cut emissions directly. Understanding offsets helps congregations engage honestly with their environmental impact. It encourages reflection on what it means to take full responsibility for one’s choices in light of stewardship and justice.

Definition: Oil dependence refers to reliance on petroleum as a major energy source. Oil has powered industrialization and modern transportation, but its extraction, refining, and burning contribute heavily to greenhouse gas emissions and pollution. Dependence on oil also creates geopolitical tensions and economic vulnerabilities. Reducing oil dependence is central to a transition toward renewable energy and climate stability.

Why it matters for people of faith: Oil dependence highlights the dangers of addiction to unsustainable resources, a theme echoed in many traditions’ warnings against idolatry or excess. For congregations, reducing oil use can demonstrate commitment to simplicity, stewardship, and justice for communities harmed by extraction and pollution. It affirms that faithfulness involves seeking freedom from systems that exploit creation. By addressing oil dependence, faith groups can witness to a vision of cleaner, fairer energy for all.

Definition: Overconsumption occurs when resource use exceeds sustainable limits, often driven by consumer culture and economic systems that prioritize growth over balance. It contributes to environmental degradation, waste, and climate change by demanding more energy and materials than the Earth can regenerate. Overconsumption is not evenly distributed, with wealthier societies using far more than poorer ones. Addressing it requires cultural as well as technological change.

Why it matters for people of faith: Many traditions warn against greed and excess, teaching instead the virtues of moderation, contentment, and generosity. Recognizing overconsumption as a driver of climate change reframes ecological care as a spiritual discipline. For faith communities, practicing simplicity becomes a way to live out values of justice, humility, and care for creation. It challenges congregations to embody an alternative vision of sufficiency rather than excess.

Definition: Permaculture is a design system for agriculture and living that models natural ecosystems. It emphasizes sustainability, resilience, and harmony with the land through practices such as polycultures, rainwater harvesting, and renewable energy integration. The goal is to create self-sustaining systems that regenerate rather than deplete resources. Permaculture extends beyond farming to inform community planning and lifestyles.

Why it matters for people of faith: Permaculture resonates with spiritual visions of living in harmony with creation. It offers a practical expression of stewardship, showing how human activity can heal rather than harm ecosystems. For congregations, permaculture gardens or landscapes can provide food, education, and habitat while witnessing to hope and renewal. It embodies a holistic approach to creation care that integrates spirituality, ecology, and community.

Definition: Pollution is the introduction of harmful substances into air, water, or soil, degrading natural systems and endangering health. It includes carbon emissions, plastic waste, chemical runoff, and light and noise pollution, among others. Pollution affects ecosystems and disproportionately harms vulnerable populations. Climate change intensifies some forms of pollution, such as smog and heat-related air quality issues.

Why it matters for people of faith: Pollution reflects human disregard for the integrity of creation, a violation of the sacred trust many traditions affirm. Faith communities can speak prophetically against systems that profit from polluting practices, standing with those most affected. By reducing pollution in their own facilities and neighborhoods, congregations live out their call to love neighbor and creation. Addressing pollution connects care for the Earth with compassion for human health and dignity.

Definition: Recycling is the process of converting waste materials into reusable raw materials, reducing the need for new resource extraction. It helps decrease landfill waste, lower pollution, and conserve energy. While not a complete solution to overconsumption, recycling is one piece of a broader strategy for waste reduction and sustainability. Its effectiveness depends on community participation and responsible systems.

Why it matters for people of faith: Recycling provides a tangible, everyday way for individuals and congregations to live out care for creation. It embodies the principle of renewal, which many faith traditions celebrate. Encouraging recycling in houses of worship can model ecological responsibility for members and neighbors alike. It demonstrates that even small acts, multiplied across communities, make a difference in caring for our shared home.

Definition: Climate refugees, sometimes called climate migrants, are people forced to leave their homes because of climate-related events such as rising seas, drought, extreme weather, or crop failure. Unlike political refugees, they often lack legal recognition and protections under international law. The number of climate-displaced people is expected to grow significantly in coming decades. Their plight raises urgent humanitarian and ethical questions.

Why it matters for people of faith: Many sacred texts call for welcoming the stranger and protecting the vulnerable. Climate refugees embody these moral imperatives in a new context, where environmental harm drives displacement. Faith communities can advocate for compassionate policies, provide direct aid, and stand in solidarity with climate refugees. Doing so expresses core values of hospitality, justice, and compassion.

Definition: Regeneration refers to restoring and renewing ecosystems, communities, and practices so they are life-giving and sustainable. Unlike sustainability, which often means maintaining current systems, regeneration emphasizes healing and improving damaged systems. Examples include regenerative agriculture, rewilding, and spiritual practices that restore balance. Regeneration seeks flourishing rather than mere survival.

Why it matters for people of faith: Regeneration resonates deeply with spiritual themes of renewal, resurrection, and transformation. It calls faith communities to envision ecological healing not as a burden but as a hopeful vocation. By engaging in regenerative practices, congregations can witness to a God- or Spirit-centered vision of abundant life. It reframes ecological work as joyful participation in creation’s renewal.

Definition: Renewable energy comes from sources that are naturally replenished, such as solar, wind, geothermal, and hydropower. These sources emit little or no greenhouse gases, making them central to addressing climate change. Renewable technologies are rapidly advancing and often bring economic benefits alongside ecological ones. They provide alternatives to the finite and polluting use of fossil fuels.

Why it matters for people of faith: Renewable energy reflects values of sustainability, stewardship, and justice for future generations. By adopting renewable energy, congregations reduce harm while modeling faithful responsibility. Many traditions honor the sun, wind, and water as gifts of creation, making their use for clean energy spiritually meaningful. Supporting renewable energy demonstrates hope and commitment to a livable future.

Definition: Resilience is the ability of individuals, communities, or ecosystems to withstand, adapt to, and recover from challenges such as climate-related disasters. Community resilience emphasizes local preparedness, mutual support, adaptive systems, local resources, and long-term strategies for sustainability. It may involve emergency planning, diverse food systems, or strengthening social networks. Resilience is increasingly important as climate change brings more disruptions.

Why it matters for people of faith: Resilience embodies the spiritual call to hope and perseverance in times of trial. Faith communities are uniquely positioned to foster resilience through networks of care, shared resources, and moral encouragement. Building resilience reflects the belief that communities can endure and adapt with compassion and creativity. It honors both human dignity and the sacredness of creation amid uncertainty. It also embodies a theology of hope—believing that even in adversity, communities can find strength, solidarity, and renewal. In this way, resilience becomes an expression of faith in action.

Definition: Solar energy is power harnessed from the sun using technologies like solar panels or solar thermal systems. It is renewable, widely available, and increasingly cost-effective. By converting sunlight directly into electricity or heat, solar energy reduces reliance on fossil fuels and cuts greenhouse gas emissions. It plays a central role in the global transition to clean energy.

Why it matters for people of faith: Many traditions honor the sun as a life-giving gift of creation. In many creation stories, light is God’s first creation. Using solar energy reflects gratitude and respect for that gift while reducing harm to the planet. Faith communities can install solar panels as a public witness of stewardship and responsibility. Choosing solar symbolizes a hopeful, forward-looking commitment to future generations.

Definition: Sustainability refers to practices and systems that meet current needs without compromising the ability of future generations to meet theirs. It integrates environmental, social, and economic dimensions, seeking balance and long-term viability. True sustainability requires shifting away from extractive habits and building systems that regenerate resources. It is both a practical goal and a guiding ethic.

Why it matters for people of faith: Sustainability echoes the spiritual principle of living in balance and harmony with creation. Faith communities can model sustainable living as an act of reverence and justice. By practicing sustainability, congregations affirm that love of neighbor includes loving future generations who are not yet born. It embodies the hope that faithful action today can secure a flourishing tomorrow.

Definition: Systems change refers to transforming the underlying structures—economic, political, cultural—that drive climate change and environmental harm. Rather than focusing only on individual behavior, systems change addresses root causes like fossil fuel dependence, industrial agriculture, or unjust policies. It emphasizes coordinated, large-scale shifts toward fairness and sustainability. Such change requires both grassroots movements and institutional leadership.

Why it matters for people of faith: Systems change resonates with prophetic traditions that call for justice, not just charity. Faith communities can bear witness to the need for structural transformation, not just personal lifestyle shifts. By engaging in advocacy, coalition-building, and moral leadership, congregations can help move societies toward greater equity and ecological health. This reflects the belief that creation care requires not just good intentions but collective transformation.

Definition: Climate tipping points are thresholds in the Earth’s systems where small changes can trigger large, irreversible effects, such as ice sheet collapse or rainforest dieback. Once crossed, these changes accelerate global warming, species decline, and adverse weather effects, and are difficult to reverse. Scientists warn that multiple tipping points may interact, leading to cascading crises. Preventing them requires urgent action to limit warming.

Why it matters for people of faith: Tipping points highlight the fragility and interconnectedness of creation. Faith traditions often warn of the consequences of ignoring moral or ecological boundaries. By understanding tipping points, faith communities can better grasp the urgency of climate action and the responsibility to prevent irreversible harm. This awareness can deepen the moral call to act with courage and foresight.

Definition: Waste reduction involves minimizing the amount of discarded materials through practices such as reusing, composting, and mindful consumption. It aims to prevent pollution, conserve resources, and reduce the strain on landfills and ecosystems. Waste reduction goes beyond recycling to address consumption habits at their source. It fosters both environmental and economic benefits.

Why it matters for people of faith: Waste reduction reflects respect for creation by refusing to treat it as disposable. Many spiritual traditions emphasize simplicity and gratitude, which align with mindful consumption. Faith communities can reduce waste in worship practices, events, and facilities as a concrete sign of their values. By modeling waste reduction, congregations teach care, humility, and responsibility to their members and neighbors.

Definition: Water scarcity occurs when demand for clean water exceeds supply, often due to drought, pollution, overuse, or climate change. It affects billions of people worldwide, threatening health, agriculture, and stability. Climate change intensifies water scarcity by altering rainfall patterns and melting glaciers. Access to water is increasingly a justice issue as inequalities in distribution grow.

Why it matters for people of faith: Water is sacred in many traditions, used in rituals of purification, blessing, and life-giving renewal. It is necessary for all life to survive. Scarcity of water raises profound moral and spiritual concerns about justice, equity, and survival. Faith communities can advocate for fair water policies, conserve water locally, and support global initiatives for clean water access. Caring for water affirms reverence for creation and love for neighbor.

Definition: Wind power generates electricity by using turbines to capture kinetic energy from the wind. It is one of the fastest-growing renewable energy sources and a critical tool for reducing dependence on fossil fuels. Wind power projects range from large-scale wind farms to smaller community-based installations. They offer clean, sustainable energy with minimal emissions.

Why it matters for people of faith: Wind often symbolizes the Spirit, breath, or divine presence in religious traditions. Harnessing wind power connects practical action with spiritual imagery of renewal and life. By supporting wind energy, congregations can align ecological practice with sacred symbolism. It demonstrates trust in creation’s gifts as part of a faithful, sustainable future.

Definition: Zero emissions refers to eliminating the release of greenhouse gases, particularly carbon dioxide, from human activities. It can be achieved through efficiency, renewable energy, and carbon removal strategies. Net zero acknowledges that some emissions may remain but must be balanced by removals. Achieving zero emissions is critical to stabilizing the climate.

Why it matters for people of faith: The pursuit of zero emissions reflects the spiritual call to do no harm and to live responsibly within creation’s limits. It offers a vision of radical transformation that aligns with hopes for renewal and healing. Faith communities can lead by setting zero-emissions goals for their own operations and advocating for broader change. Doing so demonstrates integrity, courage, and hope in action.

Definition: Zoonotic diseases are illnesses that spread from animals to humans, such as COVID-19, often exacerbated by habitat loss, industrial farming, and climate change. These diseases reveal the interconnectedness of ecological, animal, and human health. Disruption of natural systems increases the risk of new outbreaks. Addressing zoonotic diseases requires holistic approaches like “One Health,” integrating human, animal, and environmental well-being.

Why it matters for people of faith: Zoonotic diseases highlight the moral and spiritual truth that humanity cannot flourish apart from the rest of creation. Many traditions emphasize interdependence and the responsibility to protect vulnerable life. Faith communities can respond with compassion, advocacy, and ecological awareness to reduce risks. This reflects a holistic vision of healing that honors all of God’s or creation’s creatures.
