Future U.S. power suppliers will need to limit their carbon pollution, thanks to new standards announced today by the U.S. Environmental Protection Agency (EPA). The proposed emissions standards for new power plants are an important measure in implementing the President’s Climate Action Plan (announced in June) to reduce U.S. greenhouse gas emissions and mitigate global warming.
EPA’s announcement comes against the backdrop of our deepening understanding of the science of climate change. It also arrives as we witness multiple extreme weather events that present a vivid picture of what we are likely to experience in a changing world. This summer, we saw record rainfalls on the southeast coast, massive wildfires in California and Idaho, and most recently, deadly flooding in Colorado. These extreme events--to say nothing of their massive economic cost--remind us of why the United States has an obligation to cut its emissions.
As we’ve previously written, the President’s plan recommits the United States to meeting its international commitment of reducing its GHG emissions by 17 percent below 2005 levels by 2020. With these new standards--along with additional recent steps toward increasing energy efficiency and reducing emissions of potent greenhouse gases like hydrofluorocarbons and methane--the Administration is making progress in all of the sectors WRI identified in our report earlier this year.
