Religion and environmentalism is an emerging interdisciplinary subfield in the academic disciplines of religious studies, religious ethics, the sociology of religion, and theology amongst others, with environmentalism and ecological principles as a primary focus.

Within the context of Christianity, in the encyclical "Laudato si'", Pope Francis called to fight climate change and ecological degradation as a whole. He claimed that humanity is facing a severe ecological crisis and blamed consumerism and irresponsible development. The encyclical is addressed to "every person living on this planet."

Buddhism includes many principles linked to sustainability. The Dalai Lama has consistently called for strong climate action, reforestation, preserving ecosystems, a reduction in meat consumption. He declared that if he will ever join a political party it will be the green party and if Buddha returned to our world now: "Buddha would be green." The leaders of Buddhism issued a special declaration calling on all believers to fight climate change and environmental destruction as a whole.

General overview Crisis of values This subfield is founded on the understanding that, in the words of Iranian-American philosopher Seyyed Hossein Nasr, "the environmental crisis is fundamentally a crisis of values," and that religions, being a primary source of values in any culture, are thus implicated in the decisions humans make regarding the environment. For example, a 2020 study shows that religion, as the primary source of values for religious people, can help narrow the political gap between liberals and conservatives over environmental protection.

Burden of guilt Historian Lynn White Jr. made the argument in a 1966 lecture before the American Academy of Arts and Sciences, subsequently published in the journal Science, that Western Christianity, having de-sacralized and instrumentalized nature to human ends, bears a substantial "burden of guilt" for the contemporary environmental crisis. White's essay stimulated a flurry of responses, ranging from defenses of Christianity to qualified admissions to complete agreement with his analysis.

Eastern religions and indigenous peoples Some proposed that Eastern religions, as well as those of indigenous peoples, neo-pagans, and others, offered more eco-friendly worldviews than Christianity. A third, more obscure camp, argued that while White's theory was indeed correct, this was actually a benefit to society, and that thinning the populations of weaker plant and animal species via environmental destruction would lead to the evolution of stronger, more productive creatures.

Religion and ecology By the 1990s, many scholars of religion had entered the debate and begun to generate a substantial body of literature discussing and analyzing how nature is valued in the world's various religious systems. A landmark event was a series of ten conferences on Religion and Ecology organized by Yale University professors Mary Evelyn Tucker and John Grim and held at the Harvard University Center for the Study of World Religions from 1996 to 1998. More than 800 international scholars, religious leaders, and environmentalists participated in the conference series. The conferences concluded at the United Nations and at the American Museum of Natural History with more than 1,000 people in attendance. Papers from the conferences were published in a series of ten books (The Religions of the World and Ecology Book Series), one for each of the world's major religious traditions.

From these conferences, Tucker and Grim would form the Yale Forum on Religion and Ecology. The Forum has been instrumental in the creation of scholarship, in forming environmental policy, and in the greening of religion. In addition to their work with the Forum, Tucker and Grim's work continues in the Journey of the Universe film, book, and educational DVD series. It continues to be the largest international multireligious project of its kind.

An active Religion and Ecology group has been in existence within the American Academy of Religion since 1991, and an increasing number of universities in North America and around the world are now offering courses on religion and the environment. Recent scholarship on the field of religion and ecology can be found in the peer-reviewed academic journal Worldviews: Global Religions, Culture, and Ecology and in reference works such as the encyclopedia The Spirit of Sustainability.

Understanding the unique role religious leaders and faith-based communities have in play in the field of conservation, the World Wide Fund for Nature (WWF) established its Sacred Earth: Faiths for Conservation initiative by partnering with faith groups to deliver effective and sustainable conservation strategies.

Religion and nature Another landmark in the emerging field was the publication of the Encyclopedia of Religion and Nature in 2005, which was edited by Bron Taylor. Taylor also led the effort to form the International Society for the Study of Religion, Nature and Culture, which was established in 2006, and began publishing the quarterly Journal for the Study of Religion, Nature and Culture in 2007.

Religions and the environment

Interfaith cooperation Formed in 1992, GreenFaith is a global interfaith environmental coalition with more than 100 chapters (called "Circles") in the Pacific Islands, North America, Australia, Asia, Latin America, Africa, and Europe as well as religious partners in over 40 countries.Faiths 4 Climate Justice 2022 Action Guide; archived here. Focusing on grassroots activism, they encourages religious communities to invest in green energy, divest from fossil fuels, and publicly advocate for climate justice on a religious basis. As an example of their activism, in 2015, GreenFaith led the Una Terra, Una Familglia Humana () Climate Change March in Vatican City.

In 2015, over 150 leaders from various faiths issued a joint statement to the UN Climate Summit in Paris 2015 ahead of the United Nations Climate Change Conference, COP21 in Paris in December 2015. In it they reiterated a statement made at the interfaith summit in New York made in September 2014:

We as religious leaders: "stand together to express deep concern for the consequences of climate change on the earth and its people, all entrusted, as our faiths reveal, to our common care. Climate change is indeed a threat to life. Life is a precious gift we have received and that we need to care for".

Buddhism

Buddhism includes many principles linked to sustainability. The Dalai Lama has consistently called for strong climate action, reforestation, preserving ecosystems, and a reduction in meat consumption. He declared that if he will ever join a political party it will be the green party and if Buddha returned to our world now: "Buddha would be green." The leaders of Buddhism issued a special declaration calling on all believers to fight climate change and environmental destruction as a whole.

The historical Buddha and other prominent Buddhist figures gave many teachings and instructions on the importance of caring for the environment. These narratives were later written down and compiled in the Buddhist sacred scriptures.

Buddhism teaches that all things are interconnected on both gross and subtle levels. It teaches that by observing how everything in life happens due to causes and conditions coming together, people come to see how everything is interconnected in a complex web of causality. Because humans are entwined with natural systems, damage done upon the Earth is also harm done to humans. Through contemplation and investigation, people can begin to develop an understanding which takes them beyond intellectual understanding, leading humans towards realisation of more subtle and profound aspects of interdependent origination.The Karmapa, Ogyen Trinley Dorje, "Interconnected: embracing life in our global society" When people have developed this true feeling of interconnectedness, it will naturally influence the way in which humans relate to the external world.

In the First Turning of the Dharma wheel, it is taught that attachment is a cause of suffering. Siddhartha Gautama, the founder of Buddhism, spent his life searching to understand what is human suffering, what is it causes and how can one liberate themselves from this suffering.Knierim, T. (Last modified 2009). Four Noble Truths. Big View. Retrieved February 24, 2010, from

In the Buddhist tradition, the recognition of suffering as a universal experience shared by all sentient beings forms the foundation for cultivating the aspiration to alleviate their suffering. This perspective is rooted in the belief that all beings have, at some point in the vast expanse of time, been our benevolent caregivers, leading to a sense of gratitude and a desire to reciprocate their kindness. Through this understanding, compassion towards all sentient beings emerges, driven by the intention to alleviate their suffering and the underlying causes of suffering. Buddhism emphasizes that the exposure to teachings and texts is insufficient for inner transformation; true change arises from contemplation and practical application in our daily lives. Cultivating compassion requires dedicated training and practice, fostering habitual tendencies that prioritize the well-being of others. This process not only nurtures a more harmonious relationship with others and the environment but also contributes to personal growth and spiritual development.

Buddha taught that a balance must be established between self-destruction and self-indulgence.Thomas, J. (Producer) & Bertolucci, B (Director). (1994). Little Buddha. United States of America: Buena Vista Home Entertainment These days much emphasis is placed on the economic and social aspects of life and environmental aspects are often overlooked. When human preferences are leveled by developing compassion and equanimity, there is balance and harmony within the mind which has an impact on our actions of body and speech.

In summary, Buddhism provides a structured framework that aims to create not only short-term solutions to amending the broken relationship between humanity and nature,Badiner, A.H. (1990). Dharma Gaia. United States of America: Parallax Press. but it also teaches people how to fulfill their ultimate collective aspirations.

The Dalai Lama The Dalai Lama has done much to promote environmental awareness and support initiatives that help protect the environment.

In a meeting with the U.S. Ambassador to the Republic of India Timothy J. Roemer, the Dalai Lama urged the U.S. to engage China on climate change in Tibet. The Dalai Lama has also been part of a series on discussions organised by the Mind and Life Institute; a non-profit organisation that specializes the relationship between science and Buddhism. The talks were partly about ecology, ethics, and interdependence, and issues on global warming were brought up.On Climate, Ethics, Cow Burps and the Dalai Lama October 21, 2011 NYT

In 2010 he published the book Our Only Home: A Climate Appeal to the World'Our Only Home: A Climate Appeal to the World' By Dalai Lama, Franz Alt and in January 2021 was engaged in conversation on The Crisis of Climate Feedback Loops with Greta Thunberg and leading scientists William Moomaw and Susan Natali."His Holiness the Dalai Lama In Conversation with Greta Thunberg and Leading Scientists", YouTube.
