Global Electricity Review
In 2023, renewables reached a record 30% of global electricity generation, driven by solar and wind. Despite this, global power sector emissions rose by 1% to a record 14,153 million tonnes of CO2, as severe droughts caused a five-year low in hydropower, forcing a reliance on coal in countries like China and India. Solar was the fastest-growing source for the 19th consecutive year, while OECD countries continued to see falling emissions. Ember forecasts that 2023 marked the peak of power sector emissions, with a decline expected in 2024 as clean generation growth is projected to outpace electricity demand.

Tripling renewables and doubling efficiency will accelerate a fossil phaseout
The briefing asserts that tripling renewables and doubling energy efficiency by 2030 will provide 85% of the required cuts in unabated fossil fuels for that period. By 2035, these two actions alone are projected to reduce total CO2 emissions by more than half. The document emphasizes that while nuclear energy and carbon capture and storage (CCS) play roles, their contributions are significantly smaller due to slow deployment and technology immaturity, making renewables and efficiency the most effective tools for a rapid fossil fuel phaseout.

Accelerating Clean Energy Ambition
The Union of Concerned Scientists (UCS) analysis concludes that the United States can meet its climate goals through a rapid phase-out of fossil fuels and a transition to clean energy, which would yield significant economic and public health benefits. While the Inflation Reduction Act (IRA) and Infrastructure Investment and Jobs Act (IIJA) provide critical momentum, the report finds that the U.S. will fall short of its 2030 goals without additional robust policies. The most effective near-term strategy is the decarbonization of the power sector via wind and solar, while long-term reductions depend on the electrification of transportation, buildings, and industry. The report emphasizes that reducing overall energy demand can lower the required scale of new infrastructure and that a just transition must prioritize marginalized communities and hold fossil fuel companies accountable.

Accelerating Clean Energy Ambition
The Union of Concerned Scientists (UCS) analysis finds that while the Inflation Reduction Act (IRA) and Infrastructure Investment and Jobs Act (IIJA) accelerate emissions reductions, additional policies are required to meet US climate targets. Achieving net-zero by 2050 requires a rapid phaseout of fossil fuels, a massive scale-up of wind, solar, and energy storage, and expanded electrification and energy efficiency. The report argues that the health and climate benefits of this transition—including avoided premature deaths and reduced climate-caused damage—significantly outweigh the energy system costs.

The Need for US Indoor Air Quality Guidelines
The report highlights a critical gap in US public health policy: the lack of comprehensive, science-based indoor air quality (IAQ) guidelines. While the US regulates outdoor air via the Clean Air Act, indoor environments—where people spend approximately 90% of their time—remain largely unregulated. The document details how pollutants like nitrogen dioxide from gas stoves and wildfire smoke exacerbate health risks, particularly for vulnerable populations. It reviews existing international models from the WHO and Health Canada, and limited US efforts in states like California and Texas. RMI recommends that the EPA use its authority under the Superfund Amendments and Reauthorization Act (SARA) to develop federal guidelines, which could then inform building codes, product safety standards, and electrification efforts to reduce combustion pollution.

With bold leadership from business and government, we can move from fossil to clean
The We Mean Business Coalition has launched the 'Fossil to Clean' campaign to accelerate the global transition from fossil fuels to clean energy. The campaign introduces 'Fossil to Clean principles' that call for explicit end dates for fossil fuel use to provide market certainty and prevent unwise economic risks in new oil and gas projects. While over 13,000 businesses are committed to science-based emission reductions, the coalition emphasizes that government regulation is the most critical accelerator to overcome barriers such as permitting delays and lack of infrastructure. The campaign aims to mobilize business voices leading up to COP28 to push governments to include fossil fuel phase-out targets in their Nationally Determined Contributions (NDCs).

Hotter Climate, Higher Cooling Demand
Climate Central reports that 97% of 240 analyzed U.S. locations saw an increase in annual cooling degree days (CDD) between 1970 and 2022, with the most significant rises in the Southwest, South, and Southeast. Projections suggest U.S. household cooling demand will increase by 71% by 2050, while global demand is expected to more than triple. The document highlights that rising demand can strain power grids, increase greenhouse gas emissions from fossil fuels and HFCs, and exacerbate urban heat islands. It also notes a disproportionate energy burden on low-income and minority households, who may delay cooling use due to cost. Proposed solutions include transitioning to renewable energy, adopting high-efficiency heat pumps, and implementing building retrofits.

U.S. EPA Increases Crop-based Biofuels Mandate in Renewable Fuel Standard, Hampering Climate Action
The World Resources Institute (WRI) and Earthjustice oppose the U.S. EPA's finalized Renewable Fuel Standard (RFS) for 2023-2025, which increases the required volume of biofuels in transportation fuel. WRI argues that crop-based biofuels, such as corn ethanol and soy biodiesel, are inefficient compared to electrification, threaten food security by occupying 60 million acres of U.S. farmland, and increase emissions. The organization advocates for a shift toward electric vehicles and climate-smart agriculture rather than incentivizing fuel production from crops.
