Cities, states, regions, companies and investors are taking actions to address climate change. The scope of these actions is broad, covering hundreds of jurisdictions and encompassing a significant fraction of the global economy. Citizens, too, are mobilizing through signed petitions and climate marches. This ongoing action extends beyond what is captured in the Non-State Actor Zone for Climate Action (NAZCA), which records over 10,000 climate actions from nearly 5,000 actors.  An update of the broad support for climate action across a diverse range of actors follows below:

  • Over 7,000 cities from more than 99 countries, with a combined population of 794 million  (11 percent of the global population) and around 32 percent of global GDP.
  • Sub-national states and regions with a population of 779 million (11 percent of the global population) in 20 countries, covering over a fifth of global land surface area (29.9 million square kilometers) and 20 percent ($17.5 trillion USD) of global GDP.
  • Close to 5,000 companies from over 88 countries representing over $38 trillion USD in revenue.
  • Nearly 500 investors with assets under management of more than $25 trillion, one-third of total global assets.
  • Over 1.55 million people who have marched for climate action between 2014 and 2015. More than 13 million people, drawn from every country in the world, have signed petitions.
