Our Mission Inspired by diverse faith perspectives to care for the natural world and Our Mission Inspired by diverse faith perspectives to care for the natural world and its most vulnerable inhabitants, Maine Interfaith Power and Light works to engage the faith communities of Maine in efforts to counter climate change through education, advocacy, energy conservation and the use of clean renewable power 2

“If humanity wishes to preserve a planet similar to that on which civilization developed “If humanity wishes to preserve a planet similar to that on which civilization developed and to which life on Earth is adapted… CO 2 will need to be reduced from its current 387 ppm to at most 350 ppm. ” NASA climatologist Dr. James E. Hansen, 2008 3

What is the challenge? • It’s about faith groups cutting carbon dioxide (CO 2) What is the challenge? • It’s about faith groups cutting carbon dioxide (CO 2) and other greenhouse gases responsible for climate change. • We suggest a goal of at least 10% over the next year. Cutting 10% is an achievable goal and is in line with what climate scientists say we need right now. • Open to churches, synagogues, temples and all communities of faith across Maine 67
