The Inflation Reduction Act (IRA) contains $369 billion to boost clean energy and cut emissions. The law is estimated to have a greater impact on U.S. climate goals than any previous policy.
The U.S. 2030 climate target is to cut heat-trapping emissions by 50% below 2005 levels.
The IRA is projected to get the nation ~42% below 2005 levels by 2030.
Although the IRA doesn’t get the U.S. all the way to its 2030 goals, the law represents a substantial step in that direction.
Where will the emission cuts come from?
The IRA is projected to make clean energy and other climate solutions cheaper, accelerating the ongoing energy transition.
Most of the emissions cuts are expected to come from the power and transportation sectors.
In the power sector, the IRA could spur a surge in wind and solar energy. By 2026, annual capacity additions could double the 2020 pace for wind, and reach 5x the 2020 pace for solar.
In transport, the IRA is expected to make electric and zero emissions vehicles cheaper.
The IRA also includes incentives that make efficiency upgrades and low-carbon heating and cooling systems more affordable for individuals and businesses.
Impacts on health and jobs
By facilitating an unprecedented drop in emissions, the IRA would not only advance U.S. (and global) climate goals, but also boost job growth and improve air quality.
Accelerating the clean energy transition will require a boom in energy supply related jobs. By 2030, the IRA could create over 1.7 million energy supply jobs, with most of those (about 950,000) in manufacturing (mainly solar PV and wind turbine components).
Fine particulate matter pollution, a byproduct of fossil fuel-based energy production and use, can lead to illness and even death. By 2035, the IRA could avoid an estimated 63,000 premature deaths by reducing pollution from fossil fuels.
We’ve included a list of recent analyses of the IRA’s impacts on climate targets, and will provide additional reporting resources as further analyses are released.
