The member-cities of the C40 Cities Climate Leadership Group produce about 14 percent of the world’s greenhouse-gas emissions. Their actions to improve energy efficiency and invest in renewable power will reduce emissions by 248 million metric tons in 2020, Bloomberg said on a conference call. The cities can cut emissions by more than 1 billion tons by 2030, or the equivalent annual output from Mexico and Canada.Mayors, who have oversight of agencies responsible for more than three quarters of urban emissions, may be able to implement policies faster than federal governments, former U.S. President Bill Clinton said on the call. Cities that enact new rules and regulations and share their findings may help nations meet global environmental targets, such as reducing methane emissions from landfills, one of the most potent greenhouse gases.
“We can buy the world another 10 to 20 years from the worst effects of global warming if we go after methane,” Clinton said on the call. “It will improve the quality of life for everyone.”
The C40 group’s effort to reduce methane emissions will start in Dar es Salaam, Tanzania; Dhaka, Bangladesh, and the suburbs of Jakarta, Rachel Kyte, vice president for sustainable development at the World Bank, said today at a C40 press conference in Rio de Janeiro.Garbage Doubling
“The volume of garbage is going to double over the next 15 years,” she said. Taking steps to address emissions from that waste will be a “triple win,” by improving health, curbing climate change and making cities more livable. “Cities are the crucibles of innovation and it’s all going to start here.”
