There's an online software platform that measures land-based greenhouse gas emissions. It's called FLINTpro.
It's a SaaS data integration tool enabling any type of organisation to track and calculate greenhouse gas emissions from changes in land use. Inputs include - but are not limited to - emission factors, model parameters and disturbance matrices, and spatial activity data such as land cover maps. Output is information on land-sector greenhouse gas emissions.
For example, a forest clearing event is triggered in the model when the simulation unit changes from forest to cropland. This change results in the loss of carbon from the forests to the atmosphere. FLINTpro tracks each unit of carbon (or any other output variable) as it moves between pools, and maintains mass balance throughout the processes.
