The Transport Inventory and Greenhouse Gas Emission Reporting (TrIGGER) Tool estimates fuel consumption and tank-to-wheel (TTW) greenhouse gas emissions (CO₂, CH₄, and N₂O) for the transport sector in a given country and year. The tool follows the IPCC 2006 guidelines for national GHG inventories and provides default emission factors for different transport modes.
The tool has been adapted for various countries. It supports transport policy development, climate impact assessments, and emissions accounting in rapidly motorizing regions.
