Landmark legislation to reduce US greenhouse-gas emissions advanced through a key committee on 21 May in the face of staunch Republican opposition.rnThe House of Representatives Energy and Commerce Committee approved the legislation on a 33-25 vote, with 4 Democrats voting against and 1 Republican, Mary Bono Mack (California), voting aye. The bill would employ a cap-and-trade system to reduce US greenhouse-gas emissions to 17% below 2005 levels by 2020 and upwards of 80% below by mid-century.rnCommittee chairman Henry Waxman (California) crafted the bill with fellow Democrat Edward Markey (Massachusetts).
