Only a Bush-appointed EPA chief can claim progress in reducing green house gases (GHGs) when the report issued by the agency he heads states pointedly that GHG emission had risen 16% by 2004, relative to emissions in 1990. Here is a direct link to the report at the EPA:
Here is a local link to the “Fast Facts” document, which is also accessible through the above link:
US Emissions Inventory 2006
One wonders why GHG generation was down 1.3% in 2001. Could it have anything to do with airplanes not flying for a few days after 9/11? Or the economic slowdown that followed?
After examining the document, one might find it interesting that carbon dioxide emission increases as auto fuel efficiency decreases, and that emissions for electricity generation hold relatively steady. Clearly, regulations have an effect, and when cars–SUVs, specifically–aren’t regulated, the results are unsurprisingly dismal.
