"In a year when elected officials in Washington were given numerous opportunities to cast votes on issues vital to our energy future as well as clean air, clean water and key conservation initiatives, the 2005 National Environmental Scorecard offers a clear-eyed look at just where our members of Congress stand," LCV Legislative Director Tiernan Sittenfeld said.

The League criticized passage of an energy bill it called "the most anti-environmental bill signed into law in recent memory." The group contends that the bill weakens environmental protections for oil and gas drilling while adding billions in new subsidies for coal, oil and nuclear power. The League endorses further development of renewable energy.

However, the League praised Congress´ defeat of multiple attempts to drill for oil in the Arctic National Wildlife Refuge in Alaska.

The League examined each member of Congress´ voting record on key environmental issues and then calculated the percentage of votes it believed were supportive of protecting the environment.

The 2005 National Environmental Scorecard includes 45 scores of 100 percent -- 40 in the House and five in the Senate. It also includes 98 zeros -- 88 in the House and 10 in the Senate.

The average score for representatives and senators was 45.
