This monograph is intended to assist planners in Latin American and the Caribbean in understanding how to assess the Greenhouse Gas (GHG) emissions reduction benefits of sustainable transport projects, policies, and strategies. The document should aid planners accessing climate finance to support sustainable transport initiatives, as well as to assist evaluators in understanding and measuring GHG benefits of proposed investments. While the focus of the document is on measuring GHG benefits, many of the methods discussed are broadly useful for understanding other important social benefits including air pollution and traffic congestion reduction, fuel savings, increased traffic safety, and access to opportunities across the income spectrum.

The report emphasises strategies in the passenger transport sector but also includes freight strategies and methods. The primary focus is on strategies that relate to mode shifting, travel demand management, transport operations, and vehicle technology.
