BERLIN, March 1 (Reuters) - The Biden administration's effort to promote climate-friendly technologies through the Inflation Reduction Act (IRA) is attracting German companies to the United States, a survey of the German Chamber of Commerce and Industry DIHK released on Wednesday showed. According to the DIHK survey of 2,400 companies from all sectors, one in 10 German companies is already planning to relocate production to other countries. The report showed that North America, and particularly the U.S., have become more popular for business. European Union leaders have expressed concern that local content requirements of much of the $369 billion of subsidies in the IRA, which was enacted in 2022, would encourage companies to abandon Europe for the United States.
