Changing by Degrees: Steps to Reduce Greenhouse Gases

摘要

The report focuses specifically on potential emissions reductions in the next 25years. The analysis is structured around six key sectors of the U.S. economy: buildings, transportation, manufacturing, energy supply, forestry, and food. The report quantifies the potential for emissions reduction within each sector--areas where gains in efficiency, product substitution, conservation, or other technical options can ameliorate increases in carbon dioxide and other greenhouse gases. A selection of policy options that appear to offer the most promise for achieving these reductions in the U.S. is presented.
