The document advocates for clean fuel standards to decarbonize the transportation sector, which is the largest source of global warming pollution in the US. It explains how these standards use carbon intensity (CI) and a credit/deficit system to make clean fuels more affordable and polluting fuels more expensive. The text highlights the California Low Carbon Fuel Standard as a successful model and emphasizes the need for an equitable transition that benefits overburdened communities.

The report analyzes rural transportation in four Northeast and Mid-Atlantic states, finding that while rural households face barriers like lower incomes and limited charging infrastructure, they stand to gain the most financially from electric vehicle (EV) adoption due to higher mileage and less efficient existing fleets. It proposes a comprehensive strategy including EV incentives, expanded public transit, active transportation planning, and broadband expansion to reduce the need for travel.

A survey of 800 registered Michigan voters indicates a majority oppose spending $1.5 trillion to replace the U.S. nuclear arsenal and nearly $100 billion to replace land-based nuclear missiles. Voters expressed a preference for federal spending on cleaning up polluted drinking water, expanding health care, increasing job opportunities, and improving infrastructure. The data shows that women, voters of color, college-educated voters, and those in suburbs near cities are most likely to oppose the nuclear overhaul, with nearly 60% of Black voters in opposition.

The Transportation and Climate Initiative (TCI) is a regional program designed to reduce carbon emissions from the transportation sector by limiting total emissions and requiring fuel distributors to pay into a fund. This fund could generate an estimated $68 billion over ten years for participating states, including Connecticut, Delaware, the District of Columbia, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, and Virginia. The document highlights that rural residents, who drive more than 13,000 miles annually—over 20% above the regional average—stand to save up to twice as much per capita as urban residents by switching to electric vehicles (EVs). To support this transition, the author suggests higher purchase incentives for low- and moderate-income drivers, expanded rural charging infrastructure, and the growth of vanpools and paratransit services. Additionally, the document emphasizes the need for climate-resilient infrastructure, citing the damage caused by Tropical Storm Irene in Vermont as a precedent for the increasing intensity of storms in the region.

The report highlights that California's water system is engineered for historical conditions that no longer apply due to climate change. It identifies critical shifts in the state's hydroclimate—including declining snowpack, more extreme precipitation events, and increased volatility between wet and dry years—that threaten the viability of surface reservoirs and groundwater aquifers. The authors argue that while the data to plan for these changes is available, state and local agencies are underprepared, often relying on outdated operational rules or proprietary models. The report recommends updating the Sustainable Groundwater Management Act (SGMA), developing new hydrologic operations models, and increasing collaboration between climate scientists and water managers to prevent wasted investments and exacerbate inequities between well-resourced and vulnerable communities.

The document examines how climate change exacerbates water scarcity, poor water and air quality, and economic instability in the San Joaquin Valley, offering specific adaptation strategies for households and communities.

A survey of 842 registered Wisconsin voters indicates a majority oppose the estimated $1.5 trillion plan to replace the US nuclear arsenal and the $100 billion plan to replace land-based nuclear missiles. Voters prioritize federal spending on health care, job opportunities, clean drinking water, and infrastructure over nuclear weapons. Opposition is particularly high among younger voters, college graduates, non-White voters, and those in urban areas.

Climate change is intensifying wildfires in the United States by raising temperatures and drying out forests, while a century of fire suppression has increased fuel loads. These fires cause significant loss of life, property destruction, and high federal costs, while simultaneously releasing greenhouse gases that further accelerate global warming.

The Union of Concerned Scientists and UCI Law propose a framework to safeguard federal science from political, ideological, and financial influences. The roadmap focuses on reforming political appointments, strengthening the peer-review process, ensuring the balance of federal advisory committees, and preserving the independence of Offices of Inspector General.

The document outlines California's energy storage strategy, highlighting the progress made toward early procurement goals and the significant capacity increases needed by 2050. It details various storage technologies, the impact of legislative mandates like AB 2514, and the barriers to further deployment, including market rules and the need for long-duration storage to support renewable integration.

The Union of Concerned Scientists identifies systemic barriers to public participation in US federal rulemaking, noting that industry interests often have disproportionate influence and that marginalized communities are frequently excluded. The document recommends earlier community involvement, the use of plain language, increased transparency regarding funding and meetings, and improvements to digital accessibility on platforms like regulations.gov.

The document argues that the USDA's scientific integrity and research capacity were damaged between 2017 and 2020 through political suppression of research and the relocation of key agencies. It proposes a roadmap for recovery, including returning leadership to Washington, DC, implementing a suppressed climate resilience plan, and strengthening protections for scientists' communication with the public.

The Union of Concerned Scientists provides a resource for experts facing harassment, outlining how to differentiate between good-faith inquiries and disinformation tactics. It offers specific protocols for responding to attacks on social media, via email, through blogs, and in mainstream media, while emphasizing the importance of documentation, institutional support, and legal counsel.

The Union of Concerned Scientists argues that the US federal government has lacked science leadership since 2017, citing delayed appointments and reduced staffing at the OSTP. To remedy this, the document proposes a series of immediate actions for a new administration, including appointing a nationally respected scientist as OSTP director, restoring federal advisory committees, and establishing interagency working groups to address COVID-19, environmental justice, and scientific integrity. It emphasizes the need for a science-based budget and stronger whistleblower protections to prevent political interference in research.

The Union of Concerned Scientists argues that marginalized communities in the US face disproportionate environmental and health harms, which are exacerbated by systemic racism within federal agencies. The document recommends that agencies make equity-based analyses mandatory for significant policies, strengthen scientific integrity, and dismantle internal racial biases. Specific calls to action include rescinding certain EPA and CEQ rules, increasing the number of health and safety inspectors, and improving the meaningful participation of frontline and tribal communities in rulemaking processes.

The Union of Concerned Scientists (UCS) argues that the Centers for Disease Control and Prevention (CDC) must strengthen its scientific integrity to protect public health, particularly during the COVID-19 pandemic. The document details instances of political interference, such as the suppression of reports and restrictions on scientist communications, and recommends systemic reforms. These include improving whistleblower protections, dismantling systemic racism within the agency, ensuring independent science in decisionmaking, and making scientific integrity policies more accessible and transparent.

The document asserts that North Carolina's voting infrastructure is inadequate for a pandemic, citing low vote-by-mail usage and a history of gerrymandering. It links poor electoral representation to systemic issues in community health and environmental justice, recommending specific upgrades to voting access and procedures for the 2020 election.

The Union of Concerned Scientists argues that the US Department of the Interior has seen a spike in the marginalization and politicization of science since 2017. The report outlines a roadmap to strengthen scientific integrity by increasing scientific capacity, protecting communication rights, amending formal integrity policies, and addressing conflicts of interest among political appointees.

The Union of Concerned Scientists (UCS) argues that the EPA has systematically undermined scientific integrity since January 2017 through political censorship, the sidelining of expert advisory committees, and the suppression of research. The report details specific instances of scientific failure—such as the reversal of a chlorpyrifos ban and the delay of a formaldehyde assessment—and proposes a comprehensive roadmap for reform. Key recommendations include lifting hiring freezes on scientific positions, rescinding rules that restrict the use of confidential data in regulatory science, and establishing a formal process for resolving differing scientific opinions. The document also emphasizes the need to eliminate industry conflicts of interest among political appointees and to protect the rights of scientists to communicate their findings to the public without political interference.

The Union of Concerned Scientists (UCS) analyzed three methods for valuing energy efficiency in Minnesota: a coal proxy, a gas proxy, and an AVERT/gas blend. The study found that traditional utility dispatch models and locational marginal pricing (LMP) often undervalue energy efficiency by incorrectly designating low-cost renewable resources as the marginal resource, even when expensive fossil-fuel plants are operating. The analysis shows that while avoided energy costs are similar across methods ($24–$27/MWh), avoided emissions benefits vary significantly, being highest when displacing coal ($39/MWh) and lowest when displacing gas ($14–$15/MWh). UCS recommends that regulators adopt transparent, auditable methodologies and remove 'must run' constraints from dispatch models to ensure energy efficiency displaces the most expensive and polluting resources.
