GHG Protocol – Greenhouse Gas Accounting
The GHG Protocol is the most widely used international standard for greenhouse gas inventories, split into scope 1 (direct emissions), scope 2 (purchased electricity and heat) and scope 3 (15 value-chain categories). In Vietnam many listed facilities must inventory GHG under current regulations, and export customers increasingly ask suppliers for emissions data.
Criteria used by FTS Impact Lab
In the Assess tool you can check your initiative against each criterion below (met, partly met, not met, not applicable).
- Organisational boundary set (control or equity share)
- Scope 1 inventory: fuels, vehicles, refrigerants, processes
- Scope 2 from purchased electricity (location and/or market-based)
- The 15 scope 3 categories screened and largest ones calculated
- Base year, sourced emission factors and reduction target
- Data internally checked or independently verified
Example indicators to track
- Total scope 1, 2, 3 emissions (tCO₂e)
- Emissions intensity (tCO₂e per unit or per revenue)
- % renewable electricity
- % reduction vs base year
