We’ve combined science and advocacy for more than fifty years. The results speak for themselves.
Assembled below is a list of recent UCS-driven wins and major milestones, chronicling the many ways we act at the intersection of science and policy. Each success is made possible through the power of our staff, Science Network, activists, and committed members.
Recent wins
New EPA Rules Will Cut Pollution from Power Sector
For years, coal-fired power plants released mercury and coal ash into the air. The EPA’s new rules, informed by UCS analysis, limit air and water pollution from these plants and global warming emissions from coal and new fossil fuel-burning power plants.
EPA Sets UCS-Backed Vehicle Emissions Standards
The newest EPA rules will help prevent an estimated 7.2 billion tons of global warming pollution by 2055—to get there, UCS provided technical feedback, facilitated 14,000+ public comments from supporters, and rallied reinforcement in Congress.
Fenceline Communities Better Protected from Chemical Disasters
UCS has worked for years to draw attention to weak standards that do not protect workers and adjacent communities from potential chemical plant disasters. A new EPA rule strengthens requirements for such facilities’ preparedness and prevention.
Major accomplishments
UCS Research Points Finger at Big Oil for Western Wildfires
UCS peer-reviewed science shows that more than one-third of the total area scorched by forest fires in the western United States and southwestern Canada since 1986 can be directly attributed to emissions from specific fossil fuel companies.
UCS and Partners Move Toward Environmental Justice in Minnesota
Working with a coalition, UCS helped press Minnesota to enact novel legislation that will allow state regulators to protect communities exposed to multiple pollutants, by limiting or denying environmental permits to polluting projects.
Decades of UCS Work Reflected in White House Guidance
The White House’s Office of Science and Technology Policy issued a landmark framework for scientific integrity that will protect federal science from undue political interference—guidance that reflects decades of UCS research and advocacy.
UCS Successfully Advocates for US Loss and Damage Financing
At COP27 this year, countries agreed for the first time to finance a fund compensating vulnerable nations for climate-related loss and damage—a measure UCS advocated for via a joint letter from 143 organizations, and 10,000+ emails from UCS supporters.
UCS Research, Advocacy Inform Game-Changing US Climate Law
After decades of advocacy for a national plan to address climate change, UCS-backed legislation that invests billions to reduce global warming emissions is now law. This opportunity is a stepping stone to more progress for a climate-safe future for all.
CA Vehicle Standards Go Further to Reduce Pollution, Fight Climate Change
California adopted a new set of standards requiring automakers to sell more zero-emissions vehicles (ZEV), including a target of 100% ZEV by 2035. UCS analysis and advocacy helped strengthen these pollution-reducing standards from less ambitious targets.
Years of UCS Advocacy Pay Off with Historic MA Climate Bill
A robust climate bill is now law in Massachusetts, after a lengthy UCS campaign that showed its benefits for people and the economy. The law will help reduce emissions from power plants and vehicles, improving public health.
Helped Pass Climate and Equitable Jobs Act in Illinois
The new law—which UCS tirelessly advocated for with the Illinois Clean Jobs Coalition—sets a goal of 100% clean energy, while prioritizing environmental justice communities for pollution reductions.
Provided Expertise to Inform Landmark Court Ruling
A court in the Netherlands—which drew on UCS expertise—ordered Royal Dutch Shell to reduce its carbon emissions. This is the first time a company—much less a fossil fuel company—has been legally required to do so.
Ride-Hailing Will Go Electric in CA after UCS Advocacy
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.
