Holistic infrastructure for knowledge on land-use sector carbon sinks and emissions tracking (HIKET) project is funded by the Prime Minister’s Office. Its main objective is to improve understanding of carbon flows and stocks in the land use sector, as well as reduce the uncertainties related to carbon balance estimates. HIKET brings together measurements, models, and open data to strengthen cross-organizational collaboration and to build a more robust knowledge base for monitoring carbon fluxes and data-informed decision-making.
