The document argues that major carbon producers are responsible for a significant portion of the increasing wildfire risk in western North America. It attributes 48% of the rise in fire-danger conditions since 1901 and 37% of the cumulative burned forest area since 1986 to emissions from 88 major fossil fuel and cement companies. In California, wildfires between 2017 and 2021 caused over $21 billion in economic damages and released an average of 53 million metric tons of CO2-equivalent annually. The report calls for corporate accountability, legal access to justice, and state-level policies to reduce emissions, improve forest health, and protect vulnerable communities.

The Union of Concerned Scientists analysis attributes 48 percent of the rise in fire-danger conditions in western North America since 1901 and 37 percent of the cumulative burned forest area since 1986 to emissions from the 88 largest fossil fuel and cement companies. In Colorado, over 5,000 wildfires burned more than 1 million acres between 2017 and 2021, including the record-breaking 2020 Cameron Peak Fire. The document argues that these companies should be held accountable for the costs of climate change and recommends that state governments implement policies to reduce human-ignited fires, increase forest health resources, and protect vulnerable communities.

The Union of Concerned Scientists finds that 37% of the cumulative burned forest area in western North America since 1986 is attributable to emissions from 88 of the world's largest carbon producers. The report links these emissions to a rise in vapor pressure deficit (VPD), which increases atmospheric 'thirst' and dries out vegetation, thereby amplifying wildfire risk. It argues that these corporations should be held legally and financially accountable for climate damages, including the costs of wildfire suppression and recovery.

The Union of Concerned Scientists analysis finds that emissions from the 88 largest fossil fuel companies and cement manufacturers are responsible for 48 percent of the rise in fire-danger conditions in western North America since 1901 and 37 percent of the cumulative burned forest area since 1986. In New Mexico, over 4,000 wildfires burned more than 800,000 acres between 2017 and 2021, with the 2022 Calf Canyon/Hermit’s Peak Fire becoming the state's largest on record. The document argues that these companies should be held accountable for the costs of climate change and recommends that state governments implement policies to reduce human-ignited fires, increase forest health resources, protect community health, and prioritize equitable investments for low-income communities.

The Union of Concerned Scientists analysis attributes 48 percent of the rise in fire-danger conditions in western North America since 1901 and 37 percent of the cumulative burned forest area since 1986 to emissions from the 88 largest fossil fuel companies and cement manufacturers. In Oregon, over 10,000 wildfires burned nearly 3.7 million acres between 2017 and 2022, including the 2021 Bootleg Fire which burned more than 400,000 acres. The document argues that these companies should be held accountable for the costs of climate change and wildfire resilience, and recommends state-level policies to reduce human-ignited fires, improve forest health, and protect vulnerable communities.

The Union of Concerned Scientists analysis finds that 48% of the rise in fire-danger conditions in western North America since 1901 and 37% of the cumulative burned forest area since 1986 are attributable to emissions from the 88 largest fossil fuel companies and cement manufacturers. In Washington state, nearly 8,000 wildfires burned over 2.5 million acres between 2017 and 2022. The document argues for holding these companies accountable and urges state governments to implement resilience-building policies, including reducing human-ignited fires, improving forest health, and protecting vulnerable communities.

The Union of Concerned Scientists found that between FY 2019 and FY 2022, the NIH, CDC, and NIFA allocated an average of $16.2 million annually to farmworker health research, amounting to approximately $6.75 per worker. The report highlights critical data gaps regarding the synergistic effects of extreme heat and pesticide exposure, as well as a lack of research focusing on women, LGBTQ+, and Indigenous farmworkers. It recommends doubling NIFA funding to at least $16.2 million per year and increasing the use of community-based participatory research.

The document is a formal appeal to JPMorgan Chase shareholders to vote in favor of a resolution that would stop the bank from financing fossil fuel expansion. The signatories argue that continuing to fund new oil, gas, and coal infrastructure is inconsistent with the global scientific consensus required to limit warming to 1.5°C and contributes to environmental injustice and economic risk.

The document outlines the critical role of scientific research in climate litigation, emphasizing how experts can help hold corporations and governments accountable for climate damages and disinformation. It identifies key research priorities—such as attribution science and the study of climate obstruction—and provides actionable ways for scientists to engage, including serving as expert witnesses, contributing to amicus briefs, and designing research specifically relevant to legal proceedings. The Union of Concerned Scientists (UCS) Science Hub for Climate Litigation is presented as a central resource to bridge the gap between the scientific community and legal practitioners.

The guide advises consumers to first consider car-free alternatives to reduce costs and carbon emissions. For those who need a vehicle, it recommends the lowest-emission option, noting that EVs produce less than half the lifetime heat-trapping emissions of gasoline cars. It discusses the trade-offs between battery size and cost, explains three levels of charging (Level 1, Level 2, and DC fast charging), and addresses the impact of cold weather on battery range.

The guide outlines the essential components of a legislative leave-behind, emphasizing the need for a one-page document written in simple language that includes a clear recommendation, a description of the problem, supporting analysis, and a trackable 'ask'. It includes a practical example focused on urging the US Congress to meet international climate finance commitments, specifically referencing President Biden's pledge of $11.4 billion annually by 2024 and the loss and damage fund established at COP27.

The document evaluates the transition to a western RTO, arguing it could streamline clean energy deployment, improve grid reliability, and reduce costs, while warning of risks regarding California's Renewables Portfolio Standard, gas plant retirements, and governance shifts.

The document argues that adopting the Advanced Clean Trucks (ACT) and Heavy-Duty Omnibus (HDO) rules in Rhode Island would significantly reduce toxic air pollutants and carbon emissions from medium- and heavy-duty (M/HD) vehicles. By 2050, these policies are projected to reduce NOx emissions from M/HD vehicles by over 80% and PM2.5 by over 20%, leading to approximately $150 million in health care savings and over 6,000 avoided minor respiratory illnesses. Economically, the transition is expected to provide commercial fleets with over $15 million in annual savings by 2050 and eliminate over 2 million metric tons of carbon dioxide cumulatively through 2050.

The document outlines the purpose of federal public hearings as a mechanism for agencies to gather information and for the public to signal concern or support for proposed rules. It provides a practical framework for testifying, including time management (suggesting a limit of 750 words for a 5-minute slot), a structured outline for testimony (introduction, personal motivation, constructive feedback, and conclusion), and logistical advice such as submitting written copies of testimony to ensure it is documented in the public record.

The report examines the lifecycle of the Philadelphia Energy Solutions (PES) refinery, from its 2012 formation via private equity and public subsidies to its 2019 explosion and subsequent closure. It highlights how a reliance on discounted Bakken crude, high regulatory costs, and private equity management contributed to financial instability. The author argues that the lack of proactive city planning and community capacity left Philadelphia unprepared for the refinery's demise, resulting in a bankruptcy auction that determined the land's fate with minimal public input. Key lessons include the need for technical resources for community oversight, the importance of honest engagement with labor unions for worker transitions, and the increased operational risks associated with financially distressed refineries.

Virginia has four commercial sterilizers located in Richmond and Virginia Beach, with nearly 726,000 residents living within five miles of these facilities. In Richmond, the Sterilization Services of Virginia facility is linked to elevated cancer risks, with EtO emissions contributing 70 percent of the air toxics cancer risk in its census tract. The area surrounding this facility has a higher concentration of people of color and low-income residents compared to the county average. In Virginia Beach, Lifenet Health owns two sterilizers, one of which was penalized over $64,000 by the EPA for Clean Air Act violations.

The Union of Concerned Scientists argues that the United States must fulfill its international climate finance commitments to maintain global credibility and address its historical responsibility for emissions. The brief highlights a gap between President Biden's 2021 pledge of $11.4 billion annually by 2024 and the actual appropriations provided by Congress, including the December 2022 omnibus budget bill. It emphasizes the urgent need for funding to support clean energy transitions, climate resilience, and the operationalization of the loss and damage fund established at COP27 to assist vulnerable nations facing severe climate-driven disasters.

The Union of Concerned Scientists argues that the US food and farm system is dominated by industrial corporations that damage the environment and exploit workers. To address this, the brief recommends that Congress cosponsor the Agriculture Resilience Act (ARA) to increase USDA investments in agroecology, carbon capture, and climate-resilient research, and the Justice for Black Farmers Act (JBFA) to combat systemic discrimination and prevent further land loss among Black farmers.

The document reports on a survey of 378 CDC scientists conducted by the Union of Concerned Scientists and the University of New Hampshire Survey Center. While a majority of respondents agreed that the agency adhered to its scientific integrity policy, the findings highlight concerns regarding the omission of politically contentious words from scientific work and the extent to which COVID-19 science consistently informed policy decisions. The report advocates for the passage of the Scientific Integrity Act and strengthened agency policies to protect science from political, ideological, and financial interests.

A survey of 296 EPA scientists conducted by the Union of Concerned Scientists and the University of New Hampshire Survey Center found that a majority of respondents believe the agency adheres to its scientific integrity policy and that office effectiveness has increased under President Biden compared to the Trump administration. However, the findings also highlight significant issues with staff burnout and concerns over limited workforce capacity and the quality of scientific reviews in specific offices.
