Abstract
In many industrial countries voluntary commitments are emerging as a new instrument for energy policy to reduce greenhouse gases. This paper examines the latest version of the German Industry's Declaration on Climate Protection from 1996. The statistical analysis shows that the largest part of the German Industry's commitments for 2005 were already reached in 1994 and 1995, thus prior to signing the Declaration. This result corresponds to economic theory that in an open competition-based economy, companies cannot do more for the environment than the market allows.
