The Trump administration's planned rollback of vehicle emissions standards could drive staggering increases in both fuel costs and transportation emissions.

Where it stands: The White House has received from the EPA the final Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule for review. The relaxed regulations have sparked blowback from the auto industry, from California and the states that follow its stricter standards, and even from Canada, which signed an emissions-related memorandum of understanding with California.

Why it matters: Pollution is typically thought of as air, water and soil contamination, but light pollution — including from streetlights that cast excessive light — also harms the environment, human health and the stability of the global ecosystem.
