What knowledge gaps need to be addressed to implement city climate action plans? What forms of innovation are undertaken by cities to address climate change? How can these ideas be applied elsewhere? What are the current priorities of cities around the world to accelerate climate action and “green recovery” and who are the key partners and youth leaders to make it happen? Over the course of five interactive sessions, cities and their partners, per relevant global time zone, will be invited to engage in a generative space to refine and validate regional research and innovation strategies, discover and deliberate on innovation needs, opportunities and priorities.
