Non-profit scientific advocacy for public safety

Overview

Union of Concerned Scientists is a non-profit group that uses science to push for a healthy, safe, and sustainable future. It gathers scientists and engineers to develop and apply practical solutions on issues such as clean energy, clean vehicles, food and agriculture, global warming, nuclear power, and nuclear weapons. Its work combines research, analysis, and public outreach to inform policy, provide technical guidance, and drive action. The organization operates through science-based recommendations, advocacy, and collaborations with the public, government, and industry, and it is supported by more than 450,000 people. Compared with others, it differentiates itself by being a large, non-profit science coalition that directly links research to policy and real-world applications across multiple sectors. The goal is to reduce risks and create a healthier world by turning scientific findings into practical solutions and informed public policy.

  • New board members strengthen policy access as UCS pushes clean energy and science protections.

What critics are saying

  • Trump-era attacks on science funding continue crushing federal research partnerships through 2026.
  • Congress can restore grants, but December 2026 budget fights threaten UCS relevance and fundraising.
  • If federal science priorities shift permanently, UCS loses its primary policy battlefield and donor urgency.

‘Four More Years Of Chaos…’ Food & Ag Organizations Respond To Trump Victory

A resounding win for Donald Trump in the US election is prompting enthusiasm in some quarters of the food industry and intense anxiety in others.Given the lack of detail in the official Republican party platform on food and ag, meanwhile, uncertainty abounds, with stakeholders frantically picking through interviews with Joe Rogan to try and glean what could be in store. (Spoiler alert: JD Vance is not a fan of “nasty fake meat.”While Robert F Kennedy Jr (RFK) loves to talk about soil health, a key plank of regenerative agriculture, for example, Trump is a climate denier being urged to halt funding for sustainability schemes connected to food production. Similarly, RFK is advocating for tougher controls on food, drug, and ag companies to protect public health in an administration set on gutting the agencies that police them.As for Trump’s tariff plans, they clearly violate the United States-Mexico-Canada Agreement, and will likely prompt a wave of litigation and retaliation, predicted one expert we spoke to this week. But this doesn’t mean they won’t go ahead, said another. “My guess is regardless of what they’re supposed/not supposed to do, the three partners are going to do what they want.”To get an early look at how the agrifood industry is reacting to Trump’s decisive win, we’ve pulled together some statements from food and ag organizations to get a sense of what they are prioritizing in the coming months in terms of economic growth and stability, the regulatory environment, taxes and fiscal policy, trade policies and international relations, labor market and workforce development.>>Tell us what you think about the election’s impact on the agrifood industry via this super-short ​survey​ to help inform our reporting in the coming days and weeks.American Farm Bureau: “Among the most pressing issues in rural America is the need for a new, modernized farm bill.

California Legislative Committee Gives Green Light To Ev Battery Recycling Bill

Sign up for daily news updates from CleanTechnica on email. Or follow us on Google NewsProposed legislation to ensure responsible recycling of batteries once electric vehicles retire in California was approved today by the Assembly Committee on Appropriations.Senate Bill 615 would require automotive manufacturers to make certain that their electric vehicle (EV) batteries are ultimately recycled. The bill now moves forward to the entire Assembly and Senate for a vote later this month.The following statement is by Dr. Jessica Dunn, a senior analyst specializing in lithium-ion battery sustainability in the Clean Transportation Program at the Union of Concerned Scientists:“I commend California legislators for recognizing the need to plan for the safe recycling of EV batteries so that key materials can be recovered and reused, thereby reducing the amount of mining for critical minerals like lithium needed to fully electrify our transportation system over the next several decades.“Californians are buying more EVs than ever and we must start planning now for their retirements. A strong recycling policy means batteries will not end up in landfills, but instead provide an excellent domestic source of minerals for the next generation of vehicles.“Even with diminished capacity, the usefulness of batteries continues. They can be reused or repurposed and then eventually recycled so the materials recovered can be used to manufacture new batteries

New England’S Offshore Wind Resource Is A Winter Powerhouse

Sign up for daily news updates from CleanTechnica on email. Or follow us on Google NewsIt was a bitter cold day on January 5, 2018, and Massachusetts Governor Charlie Baker had no choice. An Arctic air mass had descended on New England, causing temperatures in Boston to remain below 20 degrees Fahrenheit for a week. Outside, the windchill was negative 15 degrees, and the regional grid operator was warning that the situation was dire. Demand for electricity was high, but there was not enough gas available to keep all the gas-fired power plants running. Meanwhile, the power plants that burned oil had only a few days’ worth of fuel left in their tanks.To make matters worse, the oil truck drivers, who had been working overtime to make deliveries to power plants as well as homes and businesses, had now reached state-mandated shift limits

Improved Ev Credits Makes The Switch Even Easier For Us Drivers

Sign up for daily news updates from CleanTechnica on email. Or follow us on Google NewsTo avoid the worst impacts of climate change we need to switch from gasoline and diesel to electric vehicles powered by clean electricity as soon as possible. While driving an electric vehicle (EV) can save drivers on fuel and maintenance, the upfront cost of electric cars and trucks can be a barrier to choosing an EV. The federal tax credits in the Inflation Reduction Act (IRA) are important tools to accelerate the transition and make EVs accessible to more car buyers by reducing the initial cost of both new and used EVs. The Department of the Treasury and Internal Revenue Service (IRS) recently finalized rules on these credits, including on the transfer of the new and used EV credits and mineral and battery component sourcing requirements applicable to the credit for new EVs. These rules provide greater clarity for automakers, dealers and consumers.Success of point-of-sale incentivesOne of the major changes for the Clean Vehicle Tax Credit this year was the new ability to transfer the credit at the time of sale to a dealer, reducing the upfront cost of the EV
