The report analyzes the impact of passenger vehicles manufactured before 2004 in California, finding that while they represent only 19% of registered vehicles, they produce the majority of nitrogen oxides and reactive organic gases. This pollution contributes to the formation of PM2.5, which is linked to significant health issues and premature deaths. The study demonstrates that exposure to this pollution is inequitably distributed, disproportionately affecting Latino, Black, and low-income communities, particularly in Southern California. The authors recommend prioritizing vehicle replacement incentives for disadvantaged populations and expanding non-private transportation alternatives.

The document advocates for a diverse energy mix that includes 'clean firm power'—non-weather-dependent zero-carbon sources—to complement wind, solar, and battery storage. It argues that relying solely on variable renewables would lead to excessive costs, land use, and infrastructure requirements, while a diversified approach could significantly reduce the time and cost of the energy transition.

The Stockholm Environment Institute argues that full linkage between Washington's carbon market and the California-Quebec (WCI) market currently poses risks to Washington's environmental goals due to misaligned time horizons and differing levels of ambition. Specifically, the authors highlight a large bank of unused allowances in California that could reduce in-state emission reductions and auction revenues in Washington. They recommend that full linkage be contingent on California extending its program beyond 2030 and tightening its 2030 cap. As an interim measure, the authors propose 'restricted linkage'—such as a limit on the import of WCI allowances (e.g., 2-3% of compliance obligations)—to provide cost containment while maintaining environmental integrity and revenue streams for overburdened communities.

The document examines the transition to electric semi-trucks in the U.S., noting that while they offer significant public health benefits and lower total cost of ownership, high upfront costs and limited charging infrastructure remain hurdles. It details how federal legislation, such as the Inflation Reduction Act and the Infrastructure Investment and Jobs Act, aims to accelerate cost parity and infrastructure deployment.

Colorado faces a housing shortage requiring approximately 325,000 units to stabilize prices, which currently drives suburban sprawl and increases greenhouse gas emissions. The document proposes transit-oriented development (TOD) and 'missing middle housing' as solutions to reduce vehicle miles traveled and land consumption. Specifically, RMI estimates that upzoning and infilling along transit corridors in the Denver metro could reduce per-capita vehicle miles traveled by 13% and greenhouse gas emissions by 8% by 2040.

The briefing contends that current oil price benchmarks, such as WTI and Brent, fail to account for the varying greenhouse gas emissions intensities of the oils they comprise. It highlights that oils with similar quality and price can have climate footprints that differ by a factor of two to five, creating perverse incentives. By integrating data from the Oil Climate Index plus Gas (OCI+), the author suggests that the market could better incentivize emissions reductions and allow buyers to accurately account for supply chain emissions.

Using the EPA's AVERT tool and 2021 data, the analysis finds that ignoring additionality, regionality, line loss accounting, or hourly time-matching can lead to hydrogen production emissions that exceed the threshold for the top $3/kg 45V tax credit. Specifically, forgoing additionality could result in emissions 22 to 40 kgCO2/kgH2, which is more than twice the emissions of steam methane reformation.

The document outlines a methodology to make water governance more inclusive by addressing power imbalances and recognizing diverse forms of knowledge. It introduces a 'PAR-Pathways' approach that allows stakeholders to identify their starting points, desired end-goals, and the specific activities needed to achieve equitable influence in water planning. Through four global case studies, the guide demonstrates how different pathways—including legal challenges, boycotts, and the granting of legal personhood to rivers—can lead to more just water management outcomes.

The Union of Concerned Scientists presents a framework of nine principles designed to make electric grid infrastructure planning in the Midcontinent Independent System Operator (MISO) region more equitable. These principles advocate for the prioritization of Indigenous rights, accountable decisionmaking, and procedural justice to prevent the replication of past harms. The guidance emphasizes shifting away from centralized fossil-fuel systems toward locally controlled clean energy resources, just sourcing of materials, and worker protections. It specifically calls for the adoption of the Free, Prior and Informed Consent (FPIC) standard for Indigenous communities and the implementation of social welfare metrics to benefit disadvantaged communities.

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 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 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 argues that climate coverage must expand beyond problem-focused reporting to include solutions to empower audiences and policymakers. It defines solutions journalism as rigorous, evidence-based reporting that investigates the effectiveness and limitations of responses to the climate crisis. The guide emphasizes equity and justice, noting that marginalized communities—including indigenous peoples, who manage lands containing "approximately the 80% of the biodiversity that remains in the world"—are often the most impacted yet least responsible for the crisis. It categorizes potential story leads into five areas: policy and government (e.g., carbon pricing and subsidies), economy and business (e.g., scrutinizing "greenwash" and "net zero" claims), technologies and practices (distinguishing between mitigation and adaptation), civil society (evaluating the "theory of change" behind activism), and culture (the role of arts and celebrities). The guide concludes that while not all reporting should be solutions-oriented, integrating this mindset is essential to providing a complete picture of the climate emergency.

As of December 2022, there are 5,612 committed electric school buses in the US, a significant increase driven largely by the EPA's Clean School Bus Rebate Program. While California leads in total numbers, adoption has expanded to all 50 states and is increasingly concentrated in low-income and minority communities, though the report emphasizes the need for continued focus on equity and infrastructure support.

The document asserts that nuclear energy is essential for a decarbonized global energy system to provide 'clean firm' power, reducing reliance on over-built variable renewables and expensive long-duration storage. It identifies a 'profoundly dysfunctional' current delivery model characterized by high costs and delays, exemplified by the Vogtle 3 and 4 projects in Georgia. To achieve a target build rate of hundreds of Gigawatts per year, the author proposes transitioning from bespoke construction projects to standardized, commoditized 'products' with capital costs below $4,000/kw and delivery times of 3-5 years. Key recommendations for U.S. policy include reforming the Nuclear Regulatory Commission (NRC) to adopt performance-based licensing, establishing a 'sandbox' for testing new designs, creating an International Bank for Nuclear Infrastructure, and ensuring the domestic availability of high assay low enriched uranium (HALEU).

The document lists private equity firms and the specific companies they have acquired to profit from services provided to incarcerated populations, including communications, healthcare, and commissary services.

The U.S. aims to reduce greenhouse gas emissions by 50-52% below 2005 levels by 2030. While the Inflation Reduction Act (IRA) and Infrastructure Investment and Jobs Act (IIJA) provide significant reductions, a gap of approximately 810 million tonnes CO2e remains. The Clean Air Task Force (CATF) proposes a 'high impact' scenario leveraging Clean Air Act regulatory authority and agriculture/forestry spending to close this gap.

The report finds that Nestlé's net-zero plan fails to meet any of the nine relevant UN Integrity Matters recommendations. It highlights a critical 'methane blindspot,' where the company avoids setting specific methane targets despite dairy and livestock being its largest emission sources. The analysis argues that Nestlé uses 'creative accounting' via business-as-usual scenarios to mask minimal absolute emission reductions and relies on unverified regenerative agriculture and insetting to meet goals. Furthermore, the report identifies greenwashing in the carbon-neutral claims of flagship brands like Nespresso and KitKat, which rely heavily on unreliable offsets.

Carbon Market Watch urges Verra to move away from the 'tonne-for-tonne' offsetting model, particularly for AFOLU projects, due to permanence risks and the potential for corporate greenwashing. The submission recommends adopting a 'contribution model' where finance supports climate action without claiming neutrality. It also calls for greater financial transparency regarding intermediaries, a more accessible and independent grievance mechanism for indigenous peoples and local communities, and the banning of methodologies that support fossil fuel infrastructure.

The document outlines the transition of the U.S. trucking industry toward electric semi-trucks, highlighting public health benefits and lower total cost of ownership against challenges like high upfront costs and limited charging infrastructure. It details how federal laws, such as the Inflation Reduction Act and the Infrastructure Investment and Jobs Act, as well as state-level initiatives, are working to achieve cost parity with diesel vehicles and expand charging networks.
