Hack4Climate is a 4-day Climate/Blockchain hackathon event. Its objective is to mobilize the 'blockchain'/DLT (Distributed Ledger Technology) community for #ClimateAction, assuring that the Paris Climate Agreement is successfully implemented.
Hack4Climate is held with the support of the UN Framework Convention on Climate Change (UNFCCC) Secretariat in Bonn, Germany - during the COP23 climate conference in November 2017. 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. Hack4Climate will be the first COP-linked hackathon.
