On August 16, President Biden signed the Inflation Reduction Act into law. This legislation is a $750 billion dollar health, tax and climate bill. Indeed, the inflation Reduction act is the single most significant climate legislation ever passed in the United States. So what impact will this legislation have internationally,  Including in ongoing international climate diplomacy? In this episode, we are joined by Casey Katims, executive director of the US Climate Alliance,  a coalition of US Governors representing states that account for over half the US Population. We kick off by discussing several of the key climate related provisioning included in the Inflation Reduction Act. We then discuss how this new legislation may impact diplomacy, including at a key international climate summit, known as COP27, which is being held in Egypt in November. We also discuss the unique roll that US states can play on climate related issues--something that was underscored recently when California announced that it would be phasing out the sale of gasoline powered cars.
