Carbon price and firm greenhouse gas emissions

Drawing on the recent enthusiasm in the carbon markets, I examine the impact of carbon prices on firm greenhouse gas (GHG) emissions. Using a sample of 1591 firms from 23 European countries, I demonstrate that an increase in carbon price decreases corporate GHG. At hypothesized higher carbon pricing levels, I document that the effect of pricing on corporate GHG emissions is negative. The negative impact of high carbon prices manifests in other harmful gases such as sulphur and volatile organic compounds (VOCs). In evaluating how the various phases of the EU emission trading scheme have affected firm greenhouse gas emissions, I show that the negative effect of pricing became pronounced in Phase 3 of the EU ETS. The findings from this study are robust to alternative econometric specifications and further sample selection criteria.
