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.”

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.”
