Convened by the MIT Center for Collective Intelligence’s Climate CoLab, the Crowds & Climate conferences bring together leaders from businesses, non-profit organizations, governments and communities around the world to explore the possibilities of a new technology-enabled, crowd-based approach to tackling climate change.

Climate CoLab: Crowdsourcing solutions to climate change

Inspired by the work of Wikipedia and Linux, the MIT Center for Collective Intelligence developed Climate CoLab, an online crowdsourcing platform where people work with experts and each other to create, analyze, and select detailed proposals for what to do about climate change.

Climate CoLab runs over a dozen annual contests, seeking innovative proposals for how to address a broad set of sub-problems at the heart of the climate change challenge. Contest topics include decarbonizing energy supply, changing social attitudes, and adapting to the impacts of climate change.
