Abstract

Introducing a price floor in emissions trading schemes (ETS) theoretically stabilizes expectations on future carbon prices and thus fosters low-carbon investment. Yet, ex post evidence on high carbon prices is scant and the relevance of carbon pricing for investment decisions is frequently contested. We provide empirical ex ante evidence on how a price floor in the EU ETS would impact the size and portfolio of energy firms’ investments. Analyzing survey responses of high-level managers in 113 German energy and industry companies, we find that the level of the price floor is crucial. A low price floor trajectory only provides insurance against downward price fluctuations and would leave investments largely unchanged except for industries receiving electricity price compensation, which reduce their investments. A high floor, significantly increasing the price level beyond current expectations, leads to higher investment by the majority of firms, especially by green firms, while investment in fossil energy would partially be abolished. Our studies implies that price floors can be important design components of ETS. However, policymakers need to ensure that they are at sufficiently high levels to affect investment decisions in a meaningful way.
