Deforestation – a call for consistent carbon accounting

Abstract Carbon accounting conventions treat emissions differently depending on their source. Fossil fuel carbon emissions are assessed as gross, whereas anthropogenic land carbon emissions are assessed as net. Despite calls for consistent gross accounting, accounting guidelines remain unchanged. Here we consolidate arguments for consistent accounting and explore implications for national inventories, sector contributions, carbon markets and forest protection programs. We find consistent gross accounting useful for programs supporting forest preservation, deforestation reduction and reforestation, as well as consistency with carbon markets.
