Hack4Climate, a 4-day climate/blockchain hackathon event, will take place in Bonn, Germany, from 12-16 November. It will be held in parallel with the UN COP23 Climate Change Conference, being the first ever COP-linked hackathon. Its objective is to mobilise the Blockchain/DLT (Digital Ledger Technology) community for climate action, assuring that the Paris Climate Agreement is successfully implemented. Hack4Climate accepts applications from anywhere in the world and a total of 100 participants will be invited to Bonn, while others will have the opportunity to engage online.

Hack4Climate is being held with the support of the UN Framework Convention on Climate Change (UNFCCC) Secretariat in Bonn, Germany. It is financed by public and private sponsors, and organised as part of the Climate Ledger Initiative (CLI), an international, multi-stakeholder initiative at the intersection of climate and DLT.
