This is a landmark US federal law aimed at reducing inflation by reducing fiscal deficit by USD 238 billion over three years. It also includes provisions for investment in climate change mitigation for USD 361 billion, making it the largest climate change related investment in US history. This includes investments in wind, solar and other renewables, in nuclear power, carbon capture systems for energy and industry, light and heavy duty clean vehicles, clean fuel production, green hydrogen, direct air capture facilities, as well as energy efficiency upgrades for buildings and support for heat pumps. It is expected that this will help reduce US GHG emissions by ~1 GtCO2e.
