How can greenhouse gas emissions from cities be reduced?
You are invited to submit your proposal here for cities and urban centers outside of the contest period. Try out new ideas, share your work, connect with other members and recruit collaborators, and invite a global community to review and help develop your proposal. When new rounds of Climate CoLab contests begin, you will be able to move your proposal(s) to the relevant contest. To see previous Climate CoLab contests, see the Climate CoLab contest outline view.
