Transport Inventory and Greenhouse Gas Emissions Reporting Tool


TrIGGER is a simple bottom-up spreadsheet model to calculate national transport GHG inventories. It is an open tool that can be easily adapted to any country’s needs. First developed by the Institute for Energy and Environmental Research (IFEU) together with Vietnam’s Ministry of Transport to calculate national transport-related GHG emissions and report them to the Ministry of Environment, by now the tool has been widely tested and improved.

The international TrIGGER version includes sample data from Germany to illustrate its functionality. This data does not comply with the offical GHG inventory but was simplified to illustrate the tool functionality. It can be easily replaced with country-specific data.
Find here an example of how the tool has been used in Kenya.

A comprehensive User Manual for the tool can be downloaded here.
