The proposed legislation would require automakers to sell cars and trucks that produce less emissions in the state. Environment Texas Director Luke Metzger says eleven other states have the low-emission vehicle program.
"By the year 2020, the clean cars programs that are in place in Connecticut, New Jersey and Rhode Island will reduce vehicle emissions of smog forming nitrogen oxide by 10.8% and emissions of global warming pollution by 18%."
Greater Houston Assocation for Smog Prevention Executive Director Sabrina Strawn supports the effort but doesn't want to lose focus on the greater sources of pollution.
"We really also still need to continue our focus and intensify our focus on limiting industrial admissions."
The U.S. Supreme Court is considering a case that will decide whether the Clean Air Act authorizes the Environmental Protection Agency to regulate pollution that causes global warming. The outcome of that case could determine whether the proposed clean car legislation can be implemented if passed by lawmakers. Capella Tucker, Houston Public Radio News.
