The lack of robust GHG emissions accounting including monitoring and reporting of transportation projects is one of the key barriers in supporting sustainable low-carbon transport globally. This has also been a challenging task for the GEF as the reliable and scientifically valid methodology and guidance to project managers and often the lack of capacity at the project level impeded the development and impact assessment of many transport projects submitted for GEF funding.
The Manual provides step-by-step guide for development of baseline, impact estimation and calibration of transport projects across a wide range of interventions including transport efficiency improvement, public transport, non-motorized transport, transport demand management, and comprehensive transport strategies. At the heart of methodologies included in the Manual are a series of models that streamline and provide a consistent framework for calculating GHG impact called the Transportation Emissions Evaluation Model for Projects (TEEMP). Eleven specific TEEMP models are included with the manual: bikes sharing, bikeways, bus rapid transit, employer based commute strategies, eco-driving, expressways, metro, “pay as you drive”, walkability improvement, parking, and railway.
The models provide an ex-ante estimation of the direct GHG impact of a project in a consistent way with very little local data and use conservative default values - based on research, observed results from similar projects, and expert opinion. Whenever local data is available, it can easily be inputted into the models to provide a more accurate direct GHG impact ex-ante estimation. The models have limitations to be used for ex-post impact analysis. The Manual also provides guidance on estimating direct post-project and indirect GHG emission reductions.
