All four Orange County representatives -- Reps. Verla Insko and Joe Hackney and Sens. Howard Lee and Ellie Kinnaird -- received a perfect score of 100 percent on the scorecard, which was released last week. All four also received perfect scores in 1999.
The scorecard is based on the fraction of pro-environment issues that legislators supported, as well as the environmentally damaging issues that they voted against.
This year's scorecard shows an overall decline in the environmental voting record of both the House and the Senate. The House as a whole dropped to 69 percent from last year's 79 percent rating, while the Senate dropped to 85 percent from 90 percent.
The conservation council selected the issues on which the ratings were based.
"Those were the biggest votes on the environment," said Nat Mund, the council's governmental relations director.
Insko, D-Orange, said her voting record reflects the concerns of her constituents.
"I think the environment is very important to the citizens of Orange County," Insko said. "It is one of my top priorities and a very big issue in this state."
Hackney, D-Orange, also said environmental issues are important in the Triangle area.
But Hackney said he has mixed feelings about the scorecard.
