"Justice Ruth Bader Ginsburg, who died Friday at age 87, helped establish critical Supreme Court precedent that empowered EPA to address the greenhouse gas emissions driving climate change.

The landmark ruling she joined in 2007 that affirmed EPA’s power set up the Obama administration to issue rules limiting carbon pollution from cars, power plants and other sources — and set up a contentious legal battle over the extent of federal authority still being waged today.

Though the core of her legacy centered on women’s rights and gender equality, Ginsburg was also a reliable vote over the decades in favor of environmental protections, and activists mourned her loss late Friday."
