Florida Democrats like Kathy Castor and Bill Nelson did extremely well, scoring in the 90th percentile.
Republicans like Bill Young and Marco Rubio didn't. The Pinellas representative received a score of score of 26 percent, while Rubio got a woeful 14 percent.
Other Florida Republicans from the Tampa Bay area also drew poor scores.
Pasco/Pinellas/Hillsborough County Congressman Gus Bilirakis and Polk County's Dennis Ross both received desultory scores of 9 percent; Sarasota's Vern Buchanan received a 23 percent score.
"The best that can be said about this session of the 112th Congress is that it's over," said LCV President Gene Karpinski in a press release. "In the face of Hurricane Sandy and the hottest year on record in the U.S., the House of Representatives managed to cement its status as the most anti-environmental House ever. If it weren't for the Senate and the Obama Administration, many of the public health safeguards Americans rely on would have been lost."
The only senator who has earned a 100 percent lifetime score from the LCV is Oregon freshman Jeff Merkley, who was elected in 2008.
"Clean air and water are essential to healthy families and healthy communities. I've been proud to partner with the League of Conservation Voters in my work in the Senate to protect our environment and wilderness areas and to accelerate the transition to an economy that runs on clean energy," Karpinski said.
The LCV Annual scores are based on a scale of 0 to 100 and calculated by dividing the number of pro-environment votes cast by the total number of votes scored. On the LCV website, the scorecard "represents the consensus of experts from about 20 respected environmental and conservation organizations who selected the key votes on which members of Congress should be scored. LCV scores votes on the most important issues of the year, including energy, global warming, public health, public lands and wildlife conservation, and spending for environmental programs."
