Indonesian National Carbon Accounting System (INCAS) Program – Pilot System Under the Indonesian National Carbon Accounting System (INCAS) Program, the Indonesia-Australia Forest Carbon Partnership (IAFCP) is helping to build Indonesia’s capacity in forest carbon accounting and is supporting the Government of Indonesia to develop its own sovereign national level forest carbon accounting system. In doing so, the INCAS Program is developing a pilot forest carbon accounting system. This pilot system is designed with the capability to support the Government of Indonesia’s future MRV Institution and is sufficiently flexible to meet Indonesia’s future emissions measurement and reporting requirements, once developed.
INCAS Pilot System Step 2: Change in carbon stock
Step 1: Annual land cover change Using satellite imagery, the system will monitor change in forest area annually across Indonesia. A reduction in forest area commonly releases greenhouse gas emissions, or alternatively an increase in forest area will lead to the absorption of greenhouse gases from the atmosphere.
To determine the change in forest carbon stock the pilot system incorporates on-ground biomass data with knowledge of the forest activities which caused the forest area to change.

ICARM integrates both the annual land cover change results with the change in forest carbon stocks to estimate the amount of greenhouse gas emissions released to the atmosphere and also the carbon uptake of the forest. This process can be run annually across an entire forest estate.

Step 4: Pilot account of greenhouse gas emissions The pilot system will be capable of supporting the Government of Indonesia’s future emissions reporting requirements. It will also provide a historical snapshot of greenhouse gas emissions for the 2000 decade to support informed decision making on Indonesia’s emissions reductions efforts.
