The author contends that the overturning of EPA waivers for California's car and truck standards is a temporary setback that should motivate states to accelerate the transition to zero-emissions vehicles. The document proposes a strategy involving legal challenges by California, the development of new rules like Advanced Clean Cars III, the adoption of standards by Section 177 states, and the implementation of Indirect Source Rules and Dirty Cargo Fees to address pollution hotspots.

The document details a multi-phase initiative in Ulaanbaatar, Mongolia, to combat pollution caused by the use of raw coal in 'ger' settlements. It highlights the role of the Economic Policy and Competitiveness Research Centre (EPCRC) in transitioning the community toward fuel-efficient briquettes, improving sanitation to prevent soil contamination, and influencing national green economy policies and legislation for women entrepreneurs.

The EESI briefing discusses the role of federal investments in U.S. public transit, noting that such funding supports local economies, reduces air pollution, and improves land use. It specifically highlights that every dollar invested in transit generates $5 in economic returns and explores the integration of transit with other mobility forms and land use policies.

Between 2020 and 2024, climate change increased the number of 'pregnancy heat-risk days'—days exceeding the 95th percentile of local temperatures—in every analyzed country. In 90% of countries and 63% of cities, these risk days at least doubled compared to a world without climate change. The most significant increases occurred in developing regions, particularly the Caribbean, where 15 countries saw an average of at least 60 additional risk days annually, representing roughly one-fifth of a typical pregnancy. Beyond heat, the report notes that climate-driven air pollution, flooding, and infrastructure damage further threaten maternal health and birth outcomes.

The author contends that the Trump administration and EPA Administrator Lee Zeldin are bypassing clean air laws by granting pollution waivers to coal-fired power plants and chemical manufacturers. The document asserts that the administration is distorting Section 112(i)(4) of the Clean Air Act—originally intended for extraordinary national security circumstances—to provide corporate giveaways without scientific review or public input. It highlights that 68 coal-fired power plants have already received two-year exemptions from Mercury and Air Toxics Standards, and that industry groups like the American Chemistry Council are seeking similar exemptions for over 200 chemical facilities.

The briefing highlights the failure of the UK Department for Transport (DfT) to hold auto manufacturers accountable for illegal defeat devices, which allow vehicles to exceed emissions limits. Citing ICCT analysis, it suggests 2.4 million UK vehicles may be affected. Commissioned research from the Centre for Research on Energy and Clean Air estimates that since 2009, excess emissions from these devices have caused 16,000 premature deaths and a £96bn economic burden in the UK, with further significant health and financial costs projected through 2040 if no action is taken.

The report finds that the 2025 Reconciliation bill would significantly increase household energy costs, lead to substantial job losses, and increase greenhouse gas emissions by repealing clean energy incentives and EPA standards. Despite proposed increases in oil and gas production, the analysis suggests that higher demand for fossil fuels and the loss of low-cost renewable capacity would raise overall energy spending and decrease GDP.

The document argues that the market price of fossil fuels fails to account for significant 'hidden costs' or externalities occurring during extraction, transport, and combustion. It details the severe health impacts of coal mining, such as black lung and cardiovascular disease, and the environmental degradation caused by mountaintop removal in Appalachia. The paper also examines the risks of oil and gas drilling, including methane leakage, water contamination from fracking, and catastrophic spills. Finally, it quantifies the economic burden of air pollution and global warming emissions, contrasting these with the lower impacts of renewable energy sources.

The Canadian Association of Physicians for the Environment (CAPE) argues that the 'triple planetary crises of pollution, biodiversity loss and climate change' are causing measurable harm to human health in Canada, particularly among vulnerable populations. The organization calls on federal candidates to preserve environmental regulations like the Clean Electricity Regulations and the Oil and Gas Emissions Cap, strengthen the Canadian Environmental Protection Act (CEPA), establish an Office of Environmental Justice, ban fossil fuel advertising, and enforce 'polluter pays' legislation. CAPE highlights that air pollution from fossil fuels is linked to 34,000 premature deaths in Canada annually and costs the economy $120 billion per year.

A systematic review of 187 articles finds that biomass cookstoves, used by approximately one-quarter of the global population, emit fine, organic carbon-rich particles that pose significant risks. The study reveals that real-world emission factors are consistently higher than laboratory measurements and that most improved or advanced stoves still fall into WHO polluting or transitional categories. The authors argue that current global policies fail to adequately reflect scientific evidence on particle properties.

The Clean Air Task Force (CATF) developed an in-house methodology to model the impact of the Advanced Clean Trucks (ACT) rule on diesel emissions and public health. By layering ACT's zero-emission vehicle (ZEV) sales mandates onto U.S. EPA emissions projections for 2032 and 2038, the model estimates avoided diesel fuel consumption and subsequent pollutant reductions. The analysis considers three scenarios: current adoption (11 states), expanded adoption (20 states), and full adoption across 48 contiguous states. To determine health impacts, the model uses the EPA's CO-Benefits Risk Assessment (COBRA) screening model to translate emission reductions into lives saved. For example, the model estimates that ACT enforcement in California in 2038 would reduce on-road diesel use by 547,681 gallons, representing a 16% reduction compared to a business-as-usual case, which would save 94 lives.

The Clean Air Task Force (CATF) utilizes the U.S. EPA's CO-Benefits Risk Assessment (COBRA) screening model to estimate health impacts from 2026 diesel emissions. The methodology employs a damage function approach to translate emissions into ambient PM2.5 concentrations, then into adverse health effects such as premature mortality, and finally into monetized economic damages. For 2026, national attributable premature mortality is estimated to range from 3,700 to 8,500 deaths. Additionally, CATF calculates cancer risk using a California Air Resources Board (CARB) risk factor, estimating 220 lifetime cancers per million population for 2026 based on projected concentrations of 0.25 ug/m3.

The GCHA submission argues that Chile's climate action should be framed through a public health lens to maximize health co-benefits, increase public support, and reduce the disease burden on the healthcare sector. The document recommends aligning emissions targets with a 1.5°C limit, accelerating health-related climate risk assessments, and implementing specific mitigation actions within the healthcare sector, which currently accounts for 6.7% of national emissions. It further suggests phasing out diesel subsidies, accelerating the coal phase-out date to 2030, and deprivatizing water to protect public health. The GCHA emphasizes the need for disaggregated epidemiological data to protect vulnerable groups and suggests using WHO tools to quantify the economic returns of health-promoting climate actions.

The GCHA submission argues that Nepal's climate action should be explicitly linked to public health outcomes to maximize co-benefits and protect vulnerable populations. It recommends strengthening the draft NDC 3.0 by aligning conditional emissions targets with 1.5°C limits, establishing specific targets for black carbon reduction, and creating a dedicated section on air quality. The document highlights significant health risks in Nepal, including a 68% increase in heat stress exposure since the 1990s and rising transmission potential for dengue. It also emphasizes the economic burden of climate-related health issues, noting that heat exposure caused an estimated US$2.8 billion in annual potential income loss between 2014 and 2023, with the agricultural sector bearing 91.5% of that impact.

A coalition of 123 organizations argues that dismantling the EPA's Office of Research and Development (ORD) and the Integrated Risk Information System (IRIS) would undermine the scientific basis for protecting public health from toxic chemicals. The letter specifically opposes H.R. 1415 and S. 623, asserting that IRIS provides essential, peer-reviewed toxicity evaluations used for Superfund cleanups, air toxics standards, and drinking water safeguards. The authors warn that removing these scientific resources would increase risks of cancer and birth defects, particularly in industrial areas like Geismar, Louisiana, and Houston, Texas.

The study finds that while Kenya recognizes the link between climate change and public health, the two sectors operate independently in terms of policy formulation, planning, and budgeting. Barriers to integration include a siloed institutional approach, limited funding, and a perception of the health sector as a casualty rather than an adopter of climate policies. To overcome these, the authors suggest launching a Kenya Climate Change and Health Strategy, incorporating health issues into Nationally Determined Contributions (NDCs), and adopting holistic frameworks like the One Health model.

The document examines the limited integration of health and climate policies in Germany, identifying systemic barriers such as financial constraints, federal governance complexities, and a weak science-to-policy interface. It highlights opportunities for synergy within health sector reforms and the untapped potential of climate-health co-benefits. Stakeholders recommend strengthening intersectoral collaboration, implementing binding legislative requirements, and improving the evidence base to achieve socially just and effective climate-health policies.

The document outlines the economic, health, and social benefits of transitioning Canada's passenger transport sector to net-zero. It highlights that while ZEV sales are increasing, Canada remains heavily dependent on personal vehicles due to zoning laws and a preference for light-duty trucks. The brief proposes a shift toward active transport, public transit, and ZEVs to reduce emissions, lower household costs, and create jobs in battery manufacturing and transit infrastructure.

ClientEarth supports the Hague's ban on fossil fuel advertising, asserting that EU internal market law allows such restrictions to achieve public interest goals, specifically climate change mitigation and the reduction of high-carbon consumption.

GreenLatinos asserts that President Trump's agenda rolls back environmental protections and stalls the clean energy transition, resulting in significant job losses and increased costs for working-class families.
