In 2025, countries are expected to submit a third round of nationally determined contributions (NDCs) that outline emission reduction goals for 2035. These new NDCs will be important for global alignment with the Paris Agreement's long-term goals. Setting an ambitious and plausible 2035 NDC in the United States (US) could be crucial in motivating high levels of ambition globally. This study brings together four US modeling teams to show that an expanded set of federal and state policies beyond current policies could achieve economy-wide emissions reductions of 56-67% below 2005 levels by 2035. By contrast, current policies result in 34-44% reductions. These potential policies significantly close the gap relative to the official US pledge. They also imply 2-4 times increase in renewable capacity additions, 73-100% reduction in electricity generation from unabated fossil fuels, and 83-100% share of electric vehicles in new vehicles sales. This study provides a framework for decisionmakers to use modeling as an input to inform ambitious and plausible pledges.

Under the next cycle of target setting under the Paris Agreement, countries will be updating and submitting new nationally determined contributions (NDCs) over the coming year. To this end, there is a growing need for the United States to assess potential pathways toward a new, maximally ambitious 2035 NDC. In this study, we use an integrated assessment model with state-level detail to model existing policies from both federal and non-federal actors, including the Inflation Reduction Act, Bipartisan Infrastructure Law, and key state policies, across all sectors and gases.

China is challenged with the simultaneous goals of improving air quality and mitigating climate change. The "Beautiful China" strategy, launched by the Chinese government in 2020, requires that all cities in China attain 35 μg/m or below for annual mean concentration of PM (particulate matter with aerodynamic diameter less than 2.5 μm) by 2035.
