When Cardinal Jorge Mario Bergoglio became pope in 2013, the new pontiff took the name Francis in honor of Saint Francis of Assisi, the 13th-century preacher known for a great love of animals and nature. So maybe it’s no surprise that Pope Francis recently delivered the Roman Catholic Church’s first-ever encyclical on the environment—most notably, on climate change.
“The climate is a common good, belonging to all and meant for all,” he wrote.
Catholics regard encyclicals, or official papal letters, as authoritative teachings on a particular subject. They’re meant to instruct as well to inspire action among the flock. And Francis’ flock is big—1.2 billion strong—but he’s hoping to prompt people of all creeds, at all levels of society, to join in the battle against climate change. World leaders will convene in Paris in December at the United Nations climate conference to hash out their countries’ carbon-reduction pledges.
Pope Francis will be in Paris, too, fighting for the actions he deems morally necessary to care for our “one single human family.” On that note, he is not the only faith leader who’s got climate on the mind. Here’s what the world’s other major religions have to say about the subject.
ISLAM (1.6 BILLION FOLLOWERS)
Environmental consciousness first took root in Islam in the 1970s, with many “green Muslims” turning to passages in the Koran that discussed the sacredness of nature. It wasn’t until 2009, however, that Sheikh Ali Gomaa, the Gran Mufti of Egypt—nicknamed the “Green Mufti”—announced a seven-year plan to make Islam more environmentally friendly. “Pollution and global warming pose an even greater threat than war, and the fight to preserve the environment could be the most positive way of bringing humanity together,” he said. Gomaa’s plan focused on Medina, Saudi Arabia, the religion’s second-holiest city, and included commitments to renewable energy and climate change education.
Despite these and other efforts by activists across the Muslim world, the voice of Islamic leaders has been conspicuously absent from the global dialogue on the issue. This is particularly troubling to some members of the faith since many traditionally Islamic countries are particularly prone to the impacts of climate change, such as drought and sea-level rise.
HINDUISM (1 BILLION FOLLOWERS)
As in Islam, Hindu scriptures allude strongly and often to the connection between humans and nature. These texts form the foundation of the Hindu Declaration on Climate Change, presented at a 2009 meeting of the Parliament of World Religions. In the statement, the authors accept that “centuries of rapacious exploitation of the planet have caught up with us” and state clearly that a radical change in our relationship to the planet is necessary for survival. The declaration also recognizes that “it may be too late to avert drastic climate change” and encourages compassionate responses to “such calamitous challenges as population displacement, food and water shortage, catastrophic weather, and rampant disease.”
PROTESTANTISM (814 MILLION FOLLOWERS)
EVANGELICAL PROTESTANTS: Much of the non-Catholic Christian focus on climate change has centered on denial—global warming, they say, is a natural process brought about by God, not humans. Indeed, when public figures make spectacles of those beliefs (looking at you, Senator Inhofe), they’re hard to ignore.
One group of evangelicals known as the Cornwall Alliance is responsible for fueling much of such misinformation. “There is no convincing scientific evidence that human contribution to greenhouse gases is causing dangerous global warming,” it stated in an official declaration in 2009. In April, the alliance responded directly to news of the upcoming encyclical with an open letter to Pope Francis outlining why “it is both unwise and unjust to adopt policies requiring reduced use of fossil fuels for energy” and encouraging the pope to “advise the world’s leaders to reject them.”
About 35 to 45 percent of all evangelicals, however, are not members of the denial choir. Climate scientist Katharine Hayhoe, for example, doesn’t find that her faith conflicts with the facts about human-induced global warming. “The Bible is actually very clear that there are consequences for making bad choices. Sow the seeds, bear the fruit. Climate change is the consequence of making some bad choices,” she says in a 2012 onEarth article about her efforts to reach out to her religious community. Associations like the Evangelical Climate Initiative and theNational Association of Evangelicals have also accepted that climate change is anthropogenic, and in 2013 more than 200 evangelical scientists released a lettercalling on Congress to address climate change. “Our nation has entrusted you with political power; we plead with you to lead on this issue and enact policies this year that will protect our climate and help us all to be better stewards of Creation,” they wrote.
MAINLINE PROTESTANTS: Meanwhile, many other protestant denominations have made serious commitments to combating climate change, and the United Church of Christ leads the way. It issued a resolution in 2007 admitting “Christian complicity in the damage human beings have caused to the earth’s climate system,” and in 2013, it became the first U.S. denomination to divest from fossil fuels. Episcopalians, Anglicans, and Presbyterians have all addressed the global challenges of climate change. And in 2008, prominent leaders in the Southern Baptist Church, the largest Protestant denomination in the United States with 16 million adherents, challenged the denomination’s official stance by declaring that “humans must be proactive and take responsibility for our contributions to climate change—big and small.”
BUDDHISM (488 MILLION FOLLOWERS)
You know that climate change is a serious issue if the Dalai Lama is deeming it more pressing than Tibetan independence. In a 2011 conversation with the U.S. ambassador to India, the religious leader said that “melting glaciers, deforestation, and, increasingly, polluted water from mining projects” were problems that couldn’t wait.
Before that, as part of a scientifically grounded 2009 Buddhist declaration on climate change citing the “ecological consequences of our collective karma,” the Dalai Lama endorsed the 350-parts-per-million target for carbon emissions. More recently, in 2014, he addressed the dire need for climate action: “The worst possible aspect of climate change is that it will be irreversible and irrevocable. Therefore, there is the urgency to do whatever we can to protect the environment while we can.”
ORTHODOX CHRISTIANITY (300 MILLION FOLLOWERS)
Similar to the Green Mufti, Ecumenical Patriarch Bartholomew I of Constantinople, the spiritual leader of the Eastern Orthodox Church since 1991, has earned the title of “Green Patriarch” for his dedication to environmental matters.
In 2002, Bartholomew, alongside the late Pope John Paul II, addressed the issue of environmental ethics and has since repeatedly spoken about the need to protect the environment. Last year, he delivered a message at the U.N. Interfaith Summit on Climate Change about embracing the urgency of the problem. “Each believer and each leader, each field and each discipline, each institution and each individual must be touched by the call to change our greedy ways and destructive habits.”
SIKHISM (27 MILLION FOLLOWERS)
Close to 80 percent of all Sikhs live in the Punjab region of India, an area already deeply affected by climate change. Punjab is the country’s breadbasket, and extreme drought is threatening farmers, not to mention the entire agricultural system. With this in mind, prominent Sikh leaders joined forces in 2009 to create EcoSikh, a group dedicated to “promoting care for the environment.” That year, a month before climate talks in Copenhagen, the group partnered with the U.N. and other faith groups and announced a five-year plan to help curb climate change.
Last September, EcoSikh issued an official statement on climate change, the first of its kind from a Sikh organization. “It is abundantly clear that our action had caused great damage to the atmosphere and is projected to cause even more damage if left unhandled,” it declared. “As Sikhs, we appeal to lawmakers, faith leaders, and citizens of the world to take concrete action toward reducing carbon emissions and protecting the environment. As Sikhs we pledge to take concrete actions ourselves. We have a responsibility to follow our Gurus’ teachings and protect the vulnerable.”
JUDAISM (14 MILLION FOLLOWERS)
Many Jewish groups and individuals have been addressing environmental issues for years, but they have only started making official statements and calls to action on climate change in the past several years. In 2009, Commission on Social Action to the Union for Reform Judaism issued a resolution on the “unprecedented challenge of climate change due to greenhouse gas emissions” and need for urgent action.
But as the Forward reports, the People’s Climate March in September is what first catalyzed many Jewish groups—including Conservative, Renewal, and Reconstructionist—to support the event that called on leaders to come to a strong international agreement on climate change. The Orthodox movement has been a bit more reluctant, however. Its top organizations, the Orthodox Union and the Rabbinical Council of America, steered clear of the march, worrying it could get “politically hijacked.”
BAHA’I (7 MILLION FOLLOWERS)
The Baha’i faith centers on principles like unity, justice, equality, and altruism, and its teachings promote the agreement of science and religion. It is fitting, then, that the Baha’i International Community has been publicly addressing global warming for years. In a 2008 statement, the group highlighted the need for individual, community, national, and international responses to climate change, and in 2009 presented (along with EcoSikh) a seven-year action plan to confront the issue.
Last year, Peter Adriance, the representative for sustainable development for the Baha’is of the United States, spoke out in support of the Obama administration’s new rules limiting carbon pollution from power plants. “More than purely an environmental issue, the setting of carbon standards is an issue of fairness, equity, and justice,” he said. “My hope is that our generation will be able to leave the world directed toward a better future than the one toward which we are currently headed, a world in which all people will be able to lead safe, productive, and healthy lives.”
