We investigate how cap-and-trade regulation affects profits. In late
April 2006, the EU CO2 allowance price dropped 50 percent, equating
to a €28 billion reduction in the value of aggregate annual allowances.
We examine daily returns for 552 stocks from the EUROSTOXX
index. Despite reductions in environmental costs, we find that stock
prices fell for firms in both carbon- and electricity-intensive industries,
particularly for firms selling primarily within the EU. Our
results imply that investors focus on product price impacts, rather
than just compliance costs and the nominal value of pollution permits.
