Evangelical Christian leaders from around the U.S. expressed their support for the U.S. Climate Action Plan. In an open letter to President Barack Obama and also sent to Republican and Democratic leaders of the House and Senate, the more than 170 member group states, “We see overcoming the climate challenge as one of the great moral opportunities of our time . . . That is why we write to offer our support and encouragement for your efforts to overcome the climate challenge.” The letter also expresses support for the Environmental Protection Agency’s (EPA’s) Clean Power Plan (CPP). “The CPP is an essential step, the most important one we will have made to date. . . We are glad to add our voices to the nearly 230,000 pro-life Christians who have contacted the EPA in support of the CPP.” According to the EPA, electrical power generation accounts for nearly one-third of the green house gas emissions produced in the U.S. and fossil fuel power plants are the largest source of U.S. atmospheric CO 2 . Many of the most polluting fossil-fuel electricity generating power plants are due for renovation or replacement in the near future since the average coal powered plant is 43 years old and the average oil powered plant is 46 years old. The final proposed CPP rules if adopted will reduce CO2 emissions by 32%, NOx by 72%, and SO 2 by 90% by 2030 compared to 2005 levels.
