The Inflation Reduction Act (IRA) of 2022 invests a landmark $369 billion in climate and energy investments along with tax and healthcare reforms. While the IRA creates myriad tax credits for the American people to access directly, a large portion of the funding will be applied by states, who will have a vital role in the success of the programs. If properly implemented, the IRA funds have the potential to reduce emissions up to 44% below 2005 levels by 2030. This briefing book is meant to provide insight for state legislators into the various programs and funding opportunities within the IRA in order to most effectively further their climate and conservation goals.
