INCAS has developed standard methods to quantify net greenhouse gas (GHG) emissions for the forestry sector in Indonesia in a transparent, accurate, complete, consistent, and comparable (TACCC) manner. The first version of the standard methods—described in Krisnawati et al. (2015a)—was initially tested and refined to estimate emissions and removals from forest and peatlands in Central Kalimantan as the REDD+ pilot province. These methods were improved as the coverage of INCAS was expanded to cover all provinces in Indonesia.
The standard methods describe the approach and methods used for data collation, data analysis, quality control, quality assurance, modelling, and reporting of GHG emissions and removals. Use of the standard methods ensures consistent methods are applied for every land-sector GHG inventory conducted, regardless of the geographic or temporal coverage. The standard methods include:
- Standard method—initial conditions describes the process for defining the initial conditions that are used as inputs for modelling GHG emissions and removals. This includes above-ground biomass, below-ground biomass, litter, and dead wood (woody debris) for each biomass class. For more detail click here.
- Standard method—forest growth and turnover describes the process for defining the rate of growth, turnover of above-ground and below-ground biomass, and decomposition of debris (deadwood and litter) for each component of each biomass class. These are used as inputs in modelling of GHG emissions and removals. For more detail click here.
- Standard method—forest management events and regimes describes the process for defining forest management events and regimes and their impact on carbon stocks as inputs for modelling GHG emissions and removals. For more detail click here.
- Standard method—forest cover change summarises the standard methods used to monitor changes in forest cover in Indonesia as described in The Remote Sensing Monitoring Program of Indonesia’s National Carbon Accounting System: Methodology and Products, Version 1 (LAPAN, 2014).

- Standard method—spatial allocation of regimes describes how available spatial data are used to consistently allocate management regimes to areas analysed and to derive annual area statistics by management regime for use in INCAS. For more detail click here.
- Standard method—peatland GHG emissions describes the process for quantifying GHG emissions from biological oxidation of drained peat, direct emissions from drained organic soils, and emissions from peat fire. For more detail click here.
- Standard method—data integration and reporting describes the process used to bring together data from the other INCAS standard methods (1–6) and to estimate GHG emissions and removals from activities occurring on forest lands. These include deforestation, forest degradation, sustainable management of forests, and enhancement of forest carbon stocks in Indonesia. For more detail click here.
