A Brief Summary of the Climate and Energy Provisions of the Inflation Reduction Act of 2022

This briefing by the World Resources Institute summarizes the climate and energy provisions of the U.S. Inflation Reduction Act (IRA) of 2022, detailing its financial investments in clean energy, domestic manufacturing, and environmental justice, as well as its projected impact on greenhouse gas emissions.

• The Inflation Reduction Act (IRA) is described as the largest single step taken by Congress to address climate change, allocating nearly $370 billion to investments in disadvantaged communities, with a focus on employing displaced workers and repurposing retired fossil fuel infrastructure.
• Modeling from the Rhodium Group indicates that the IRA increases projected U.S. greenhouse gas (GHG) emission reductions by 2030 to between 31% and 44% compared to 2005 levels, up from a business-as-usual projection of 24% to 35%. When combined with actions from states, cities, and executive agencies like the Department of Agriculture and the EPA, the U.S. may meet its nationally determined contribution (NDC) target of 50-52% reduction.
• The IRA implements a 10-year runway for energy tax incentives to provide economic certainty for developers and manufacturers. Starting in 2025, clean electricity tax credits will become "technology-neutral," applying to zero-carbon sources including nuclear, geothermal, solar, and wind. Additionally, the U.S. Department of Energy’s Loan Programs Office will see a $250-billion expansion of its financing authority.
• To support domestic manufacturing, the IRA provides $30 billion in expanded production tax credits for batteries, wind turbines, solar panels, and critical minerals processing, plus a $10-billion investment tax credit for clean energy manufacturing. This includes nearly $6 billion specifically for reducing emissions in heavy manufacturing sectors like cement and steel.
• The legislation establishes the Greenhouse Gas Reduction Fund, a $27 billion green bank. This fund allocates $12 billion for renewable energy projects nationwide, $8 billion for technical and financial assistance for low-income and disadvantaged communities, and $7 billion for air-pollution abatement and rooftop solar in disadvantaged communities. A separate $3 billion is allocated for environmental and climate justice block grants.
• The IRA provides tax credits for electric vehicles (EVs), though eligibility is tied to North American assembly and battery component sourcing. To qualify, vehicles must be assembled in North America, and by 2023, over 50% of battery components must be manufactured or assembled in North America or countries with a U.S. free trade agreement (rising to 100% by 2029). Credits are prohibited if components or critical minerals are sourced from a "foreign entity of concern," such as China, starting in 2024 and 2025 respectively.
