A climate-change law passed by the Mexican Legislature will be one of the strongest national climate-change laws on the books, environmentalists said. The bill passed in Mexico's lower house on 19 April with a vote of 128-10 and was later passed unanimously by the Senate, Nature reported. Passed after three years of debate and revisions, the bill contains sweeping provisions to mitigate climate change, including a mandate to reduce emissions of carbon dioxide by 30 percent below current levels by 2020 and by 50 percent below 2000 levels by 2050.
