Nature: Today, President Obama is announcing a set of regulations to limit greenhouse gas emissions from power plants over the next 15 years. The primary goal will be a 32% reduction from 2005 emissions levels by 2030 for the entire electricity-generating industry. The regulations set targets for each state and require each state to submit, by 2016, plans to reach those targets. However, the states can request a 2-year extension and participate in emissions trading. The regulations will not go into effect until 2017. Even though they don’t require congressional approval, the regulations are expected to be challenged by Republicans in Congress and the coal industry.
