Cities Could Save $17 Trillion Just By Reducing Their Greenhouse Gas Emissions

Making cities greener could save a lot of, well, green, according to a new report.

The report, published Tuesday by the New Climate Economy, found that if cities around the world implemented certain carbon-reducing strategies — including making buildings more efficient and investing in public transportation — they could save a combined total of $17 trillion by 2050.

The report looked at actions such as “aggressively” deploying high-efficiency lighting, “ambitiously” installing solar on buildings, increasing the fraction of methane captured from landfills, and expanding public transit. It found that, if all of the measures were implemented, cities would reduce their combined greenhouse gas emissions by 3.7 metric gigatons of carbon dioxide equivalent by 2030. That’s more, the report notes, than the annual emissions of India.

Nick Godfrey, head of policy and urban development at the New Climate Economy, said in a statement that the amount of money saved by cities could be even higher.
