The Climate Action Network (CAN) is a worldwide network of over 900 Non-Governmental Organizations (NGOs) in more than 100 countries, working to promote government and individual action to limit human-induced climate change to ecologically sustainable levels.

CAN members work to achieve this goal through information exchange and the coordinated development of NGO strategy on international, regional, and national climate issues. CAN has regional network hubs that coordinate these efforts around the world.
