The Union of Concerned Scientists argues that the US can technically achieve a 50% reduction in heat-trapping emissions by 2030 and net-zero by 2050 through widespread electrification and renewables. However, it emphasizes that carbon-only modeling is insufficient; a transformative transition must actively dismantle structural racism and economic inequality by prioritizing marginalized communities, ensuring a fair transition for fossil fuel workers, and shifting power from corporate interests to community governance.

The document details a modeling framework combining EnergyPATHWAYS (EP) for demand-side stock accounting and the Regional Investment and Operations (RIO) model for supply-side least-cost optimization. It outlines nine scenarios for the U.S. energy transition, including a 'Zero CO2 2050' case and various electric vehicle (EV) adoption speeds. The methodology emphasizes high temporal and spatial resolution, co-optimizing electricity and fuel systems to meet economy-wide emissions constraints.

The report analyzes how a $55 billion annual federal investment in clean energy and land restoration could generate nearly 260,000 rural jobs and $21.7 billion in annual value added for rural US economies. It identifies seven priority investment pathways: renewable energy, energy efficiency, grid modernization (transmission, distribution, and storage), environmental remediation of fossil fuel sites, tree restoration on federal and non-federal lands, and wildfire risk management. The analysis emphasizes that nearly 45% of these jobs would benefit economically disadvantaged rural counties. The document provides specific state-level data and proposes federal policy vehicles, such as tax credits and grant programs, to catalyze these investments.

The 2021 State of Cities Climate Finance report finds that annual urban climate finance averaged USD 384 billion in 2017/2018, which is significantly lower than the estimated annual need of USD 4.5 to 5.4 trillion. Investment is heavily concentrated in OECD countries and China, with critically low levels in South Asia and Sub-Saharan Africa. The report emphasizes that while cities act as providers of infrastructure and stewards of regulation, their ability to mobilize finance depends on national-level governance, city-level capacity, and the alignment of climate-specific financial instruments. It recommends strengthening municipal finance fundamentals, integrating carbon pricing into capital planning, and utilizing catalytic funding to de-risk private investment in developing economies.

Egypt's updated NDC outlines a comprehensive strategy to mitigate greenhouse gas emissions and adapt to climate change by 2030. The plan focuses on transitioning the electricity sector to 42% renewable energy, reducing associated gas flaring in the oil and gas sector by 65%, and shifting transport toward low-carbon mass transit. Adaptation priorities include rehabilitating 20,000 km of irrigation canals, protecting the Nile Delta from sea-level rise, and enhancing agricultural resilience. Implementation is heavily dependent on international financial support, with an estimated total requirement of USD 246 billion.

The document analyzes the dual potential of autonomous vehicles (AVs) to serve as a climate solution or an environmental liability. While AVs could reduce emissions through electrification, platooning, and shared transit, the proliferation of single-occupancy AVs risks increasing vehicle miles traveled (VMT) and urban sprawl. The brief emphasizes that achieving climate goals requires integrating AVs into multimodal, electric urban systems that prioritize mass transit, biking, and walking over private vehicle use.

Fossil-fuel burning appliances in the US contribute significantly to outdoor and indoor air pollution, climate change, and public health disparities. Gas appliances are particularly problematic, emitting more than twice as much NOX as gas power plants. RMI proposes that the EPA implement a NOX standard of performance under Clean Air Act Section 111(b), requiring all new appliances to be electric by 2030. This transition could avoid over 500,000 tons of NOX and 14,400 tons of PM2.5 annually by 2045, potentially saving over 3,750 lives per year and providing $21 billion in annual economic benefits. The document emphasizes that electric appliances are cost-effective and that policies should include incentives to ensure low-income consumers can access these technologies.

The report presents survey data from 922 registered U.S. voters, revealing broad support for various climate-friendly energy and conservation policies, though opinions on economic impacts and the urgency of federal action remain sharply divided along political lines.

Between January 2020 and March 3, 2021, G7 nations invested more in fossil fuels (US$189 billion) than in clean energy (US$147 billion), despite pledges to achieve net-zero emissions by mid-century. The report finds that over 80% of fossil fuel funding lacked 'green strings' or climate targets, while only 10% of COVID-19 response funds supported the cleanest energy measures. To align with the Paris Climate Agreement, the report recommends that the G7 end support for fossil fuel production, increase green recovery spending to at least 40% of total COVID-19 recovery funds, and double climate finance pledges to assist low- and middle-income countries.

The report estimates that an average of USD 384 billion was invested annually in urban climate finance during 2017-2018, a figure significantly lower than the estimated annual need of USD 4.5 to 5.4 trillion for low-emission and resilient urban infrastructure. Mitigation efforts, particularly in sustainable transport and green buildings, dominate the landscape, while adaptation finance remains severely underfunded, representing only 9% of tracked project-level data. The analysis highlights a geographic imbalance, with the majority of finance flowing to China and developed economies, while regions like Sub-Saharan Africa and South Asia remain critically underfunded. Key barriers to scaling this finance include low creditworthiness of city governments, a lack of bankable projects, and institutional restrictions on local borrowing.

The report argues that stopping the expansion of fossil fuels is insufficient to meet the 1.5°C target of the Paris Agreement; instead, an active wind-down of existing production is required. It proposes specific annual decline rates for coal (9.5%), oil (8.5%), and gas (3.5%) between 2021 and 2030. The authors conclude that this transition is technically feasible because global solar and wind potential could meet primary energy demand more than 50 times over, ensuring 100% energy access without risking energy security.

The report finds that international public financing for gas projects in low- and middle-income countries is four times higher than for wind or solar, creating a 'lock-in effect' that threatens climate goals. It argues that gas is no longer a necessary 'bridge technology' because renewables are often cheaper and more effective for energy access. The document recommends that international financial institutions cease all support for gas infrastructure and instead fund grid integration, technology transfer, and a just transition for affected workers.

The report finds that international public finance disproportionately supports natural gas in low- and middle-income countries, often exceeding support for wind and solar by four times. It argues that the 'bridge fuel' narrative is obsolete due to the falling costs of renewables and the risks of stranded assets and methane leaks. The document recommends that international financial institutions cease funding gas infrastructure and instead support clean energy integration, technology transfer, and a just transition, particularly for the poorest nations.

The report finds that international public finance disproportionately supports natural gas over renewables in the Global South, creating risks of stranded assets and carbon lock-in. It argues that renewables are now cost-competitive for most gas uses and recommends that public financial institutions cease support for gas infrastructure to prioritize clean energy transitions.

Power Forward 4.0 finds that 60% of Fortune 500 companies have set at least one climate or energy target, a 12-percentage-point increase since 2017. While GHG reduction targets are most common (54%) and Science-Based Targets (SBTs) have increased sixfold, only 20% of the Fortune 500 have set or committed to an SBT. The report highlights a rise in net-zero commitments (17%) and 100% renewable energy targets (58 companies), though it notes significant gaps in the financial, fossil fuel, and retail sectors. Despite progress, the report argues that voluntary action is insufficient and calls for federal and state policies, such as carbon pricing, to align the US private sector with the Paris Agreement and the US Nationally Determined Contribution.

The Green Climate Fund (GCF) emphasizes that advancing gender equality is critical for a climate-resilient future, as women are disproportionately affected by climate change yet act as key agents of change. The GCF mandates gender mainstreaming across all interventions through its Governing Instrument and Gender Policy, requiring every project to include a Gender Action Plan. The Fund has committed to providing $10 billion annually in support designed to optimize co-benefits between climate action and gender equality. Specific examples of this approach include supporting women-led agricultural enterprises in Ghana, argan tree cooperatives in Morocco, clean energy enterprises in Mongolia, and off-grid renewable energy SMEs in Kenya and Rwanda via the KawiSafi Ventures Fund.

The report identifies significant energy and emission reduction potentials through the adoption of 'Green ACs' in public buildings, while highlighting financial, political, and technical barriers that hinder the implementation of Green Public Procurement.

The report argues that the COVID-19 pandemic has exacerbated debt vulnerabilities in low- and medium-income countries, potentially hindering climate action. It advocates for Debt for Climate (DFC) swaps, where external debt payments are redirected toward domestic climate projects in local currency, to reduce indebtedness and stimulate green investment.

The briefing outlines six funding models—sales taxes, retail taxes, fossil fuel production taxes, electricity consumption taxes, climate bonds, and resilience bonds—that US cities have implemented to fund climate action. It highlights specific examples from cities like Denver, Portland, and Miami, emphasizing that integrating equity into the design of these funding streams is essential for success, particularly for Black, Indigenous, Latino, and low-income communities who are disproportionately affected by pollution and climate change.

The report examines the disparity between cost-effectiveness and equity-based criteria for determining national emissions reduction targets under the Paris Agreement. It suggests that international support can bridge this gap, provided it avoids carbon lock-in and considers socio-economic contexts. The document also highlights how domestic political shifts in countries like Brazil and the United States create spill-over effects globally, and argues that the European Union can accelerate global transformation by adopting a more ambitious 2030 goal and a robust institutional setup for its 2050 climate neutrality target.
