Independent research organisation Worldwatch reports that 228 cities around the world are taking the lead on climate action, setting greenhouse gas reduction goals or targets. Worldwatch says that action in these cities, which represent a combined population of 439 million people, could mean countries meet their Intended Nationally Determined Contributions (INDCs) the national greenhouse gas reduction pledges in the Paris Agreement.

According to Can a City Be Sustainable?, the latest edition of the annual State of the World series from the Worldwatch Institute, cities and their inhabitants are playing a lead role in achieving global climate action goals (


The Institute reports that the C40 Cities Climate Leadership Group has expanded to more than 80 cities and the Compact of Mayors, launched at the 2014 United Nations Climate Summit, is the largest coalition of city leaders addressing climate change. ICLEI-Local Governments for Sustainability works with more than 1,000 cities around the world.

It reports that cities collectively account for a large share of greenhouse gas emissions, because they concentrate economic activity. But cities vary widely in their per capita emissions. Rotterdam in the Netherlands, for example, emitted 29.8 tons of carbon dioxide-equivalent per capita in 2005, while Paris emitted just 5.2 tons per capita. Variables, such as climate, urban form, and primary energy source, affect a city’s level of emissions and economic factors, such as the wealth and income of residents, and the level and structure of economic activity, also play a major role.
