High energy prices in Europe and uncertainty caused by the Ukraine war are testing EU firms' ability to invest in climate change measures. Europe urgently needs to embrace the transition to green energy, and firms will be called upon to play a pivotal role. By investing in climate adaptation and mitigation measures, especially energy efficiency, firms will be able to protect themselves against extreme climate events, reduce energy costs and take the actions needed to reduce carbon emissions to net-zero by 2050. The report What drives firms' investment in climate action? Evidence from 2022-2023 EIB Investment Survey uses data collected from firms to provide insight on how businesses are responding to the energy crisis and the fast-changing business environment.
