State Sen. Bob Duff, D-Norwalk, chairman of the Energy and Technology Committee, received a perfect score from the Connecticut League of Conservation Voters on its 2014 Environmental Scorecard, which rates Connecticut's state legislators by the votes they have cast on key environmental bills, according to a news release.

"The health of Connecticut's air, soil and water supply is critically important to our quality of life and economy," Duff said. "By acting now and making smart, strategic investments in renewable energy, remediation and conservation projects, we can ensure that Connecticut is the best place to live, work and raise a family."

This year, Duff helped to pass new regulations that will clear the way for construction of new wind power in Connecticut, lifting a moratorium.

The major issues tracked by the league in 2014 were open space protection, state parks stewardship, tree trimming, water planning, Long Island Sound protection, genetically modified grass seed, children's exposure to pesticides, toxins in the environment, chemicals of high concern for children, fracking waste, methane gas leaks from natural gas delivery systems, outdoor wood-burning furnaces, the public's right to comment on subdivision applications, repeal of environmental regulations and exemption from penalties for first-time violators of environmental regulations.

Earlier this year, Duff was recognized as a Clean Energy Champion by the New England Clean Energy Council.
