The cost of increasing ecosystem carbon

Increasing the organic carbon stored in biomass and soils holds great promise to help mitigate climate change. Over the past two decades, a number of studies have attempted to estimate the cost, but results have been contradictory. Forest ecologist Markku Larjavaara, alongside other scientists from the University of Helsinki, the Center for International Forestry Research (CIFOR) and the University of Turku, set out to narrow this knowledge gap using a simple but innovative approach.
