Responding to UCS analysis of ride-hailing's climate risks, California passed groundbreaking legislation that requires companies like Uber and Lyft to have 90% of miles traveled carbon-free by 2030. This will serve as a model for other states.

UCS organized—and promoted in national media—a scientists’ sign-on letter with more than 1,500 signatures, calling on the administration to set a target cutting emissions 50 percent below 2005 levels by 2030. The White House has adopted those targets.

In a step towards decarbonizing transportation and lowering emissions in Washington state, its legislature passed a clean fuels standard bill that UCS and partners have spent years campaigning for.

Included in the Biden administration’s coronavirus relief package is $5 billion in funding that begins to address staggering land losses among Black farmers. These provisions were identified and advocated for by UCS and the HEAL Food Alliance.

UCS has called for the EPA to correct the corruption of federal science advisory boards by the prior administration; the agency announced it will reset advisory board membership, prioritizing qualified scientists who have no conflicts of interest.

For two years, UCS worked to strengthen and promote a bill—now signed into law—that commits Massachusetts to net-zero emissions by 2050 and addresses racial disparities in the benefits and burdens of clean energy and climate-related policies.
