Our eight Challenge Categories for COP28 are all connected closely to the effects of climate change. The specific challenges within each category are created in collaboration with Hack for Earth partners, and will be announced closer to the opening of the hackathon.

‍The competing hacker teams will first choose a category and then choose a specific challenge within that category. A challenge is most often shaped as a question. Feel free to start brainstorming on what challenge category you wish to tackle!
