  If goals set under the Paris Agreement are met, the world may hold warming
well below 2 C; however, parties are not on track to deliver these commitments,
increasing focus on policy implementation to close the gap between ambition and
action. Recently, the US government passed its most prominent piece of climate
legislation to date, the Inflation Reduction Act of 2022 (IRA), designed to
invest in a wide range of programs that, among other provisions, incentivize
clean energy and carbon management, encourage electrification and efficiency
measures, reduce methane emissions, promote domestic supply chains, and address
environmental justice concerns. IRA's scope and complexity make modeling
important to understand impacts on emissions and energy systems. We leverage
results from nine independent, state-of-the-art models to examine potential
implications of key IRA provisions, showing economy wide emissions reductions
between 43-48% below 2005 by 2035.
