In 2006, to address growing ecological awareness and the need to implement Catholic social teaching on ecology within the US Church, the United States Conference of Catholic Bishops (USCCB) helped form Catholic Climate Covenant. Inspired by the USCCB's 2001 statement on climate change, and supported by 18 national partners (which include the USCCB, Catholic Relief Services, Catholic Charities USA, the Catholic Health Association, congregations of religious men and women, and other national organizations), Catholic Climate Covenant helps US Catholics respond to the Church's call to care for creation and care for the poor.

Catholic Climate Covenant is grounded in the Church's deep history of teaching on creation, ecology, and the poor. Caring for creation and caring for the poor have been a part of the Catholic story since the beginning, but in recent years St. John Paul II, Pope Emeritus Benedict XVI, and especially Pope Francis have added a sense of urgency to their call for Catholics to act on climate change. The US Bishops themselves having been calling for action since 1981.

Catholics do care about climate change and they're working hard to create solutions. Catholic Climate Covenant is at the center of these efforts. With the approval and support of the United States bishops, they help guide the US Church's response to the moral call for action on climate change by sharing authentic Catholic teaching on creation and the poor and by informing and inspiring community leaders to take action (education); by sharing stories of those most affected by climate impacts in the public square (public witness); and by providing concrete tools, techniques, and technical assistance to help Catholic peoples and institutions reduce their carbon footprint and to work for justice (resources).
