Megacity mayors chart road maps to cut carbon emissions – Christian Science Monitor

The Megacities Carbon Project was launched in 2012 to solve a pressing scientific problem: how to measure the greenhouse gases that cities produce. Urban areas generate at least 70 percent of the world’s fossil fuel carbon dioxide emissions, but gauging a city’s carbon footprint remains difficult due to the lack of effective measurement methods. The project aims to change that by developing and testing techniques for both monitoring urban areas’ emissions and determining their sources.

Key Takeaways:

  • If we are going to avoid the worst impacts of global warming, cities are going to have to play an even bigger role in the months and years ahead,” former New York Mayor Michael Bloomberg, a UN special envoy for climate change and the C40 board president, told reporters, according to Agence France-Presse.
  • Together, the C40 cities account for one quarter for the global economy and house more than 650 million people.
  • Wealthy cities with high levels of CO2 emissions, such as New York, would be expected to immediately cut carbon pollution, while poorer cities with high per capital CO2 output, would be granted a brief period of increasing emissions before making cuts.
