Retired Supreme Court Justice John Paul Stevens, who died yesterday at age 99, wrote the landmark 5-4 decision in 2007 that clearly gave EPA the power to regulate GHG emissions.
Why it matters: EPA began acting on that authority during the Obama years. Major rules include emissions standards for cars and power plants, which the Trump administration is weakening.
The International Energy Agency on Tuesday issued a report making the climate case for natural gas — with important caveats — and unveiled a tool for tracking methane emissions from oil-and-gas development.
What they did: The report explores the past (see chart above) and potential of replacing coal-fired power and heating with gas.
