How Much Could the US Inflation Reduction Act Cost Europe?

The Inflation Reduction Act (IRA) was introduced in the US in August 2022, aiming to promote investments into clean energy production. The IRA provides huge amount of aid, which can have a draining effect of green investments vital for the green transition of the European economy. In response, the Commission adopted Temporary Crisis and Transition Framework (TCTF) in March 2023. As well as explaining the historical context and content of these subsidy-rules, this article makes an attempt to compare the subsidies available under the IRA and the TCTF, considering the maximum aid amount available under the regional aid guidelines.
