New York City Mayor Michael Bloomberg and Rio de Janeiro Mayor Eduardo Paes said that four-dozen cities in the so-called C40 Cities Climate Leadership Group are reducing emissions by launching energy efficiency programs, capturing methane in city landfills, installing more efficient street lighting, and other initiatives.
They cite the CO2 reductions as proof that the world's cities can make significant progress on slashing greenhouse gases even in the absence of a global agreement on cutting carbon emissions. "We're not arguing with each other about emissions targets," Bloomberg told reporters in a teleconference.
"What we're doing is going out and making progress." Bloomberg and Paes said that 59 cities have committed to cut their carbon emissions by a total of 1 billion tons by 2030, equivalent to the combined greenhouse gas emissions of Canada and Mexico.
