Evaluation of California Greenhouse Gas Standards and Federal Energy Independence and Security Act - Part 2: CO2 and GHG Impacts
2008-05-12

This is the second of two papers that examine the future effectiveness of the California greenhouse gas “GHG” program and the federal fuel economy program established in the Energy Independence and Security Act of 2007 (“EISA 2007”) in controlling greenhouse gases. SAE 2008-01-1852 estimates the fuel economy levels that the California and federal programs can be expected to require, under assumptions stated in that paper. This paper applies those fuel economy estimates to examine the impact of the California and federal programs on lifecycle emissions of GHGs and carbon dioxide (“CO2”). EISA 2007 not only proposes to improve car and LDT fuel economy, but it also proposes to reduce GHGs through its Renewable Fuel Standards (“RFS”) provisions, which are likely to lead to substantial expansion in the use of 85% ethanol gasoline blends (E85).
