Korean Transport Institute Methodology for Estimating Greenhouse Gas and Air Pollutant Emissions Related to Road Networks. This study is aimed at developing new procedures for estimating greenhouse gas and pollutant emissions related to road networks. Under this goal, the study suggests two approaches: one is based on vehicle information obtained through detectors, while the other uses the results of a transport planning model.

The  Global Protocol for Community Scale GHG emissions developed by ICLEI and the C-40 helps cities around the world measure and report GHG emissions using a more consistent protocol. Transport is covered from page 41-54.

COPERT 4 is a software tool used world-wide to calculate air pollutant and greenhouse gas emissions from road transport. The development of COPERT is coordinated by the European Environment Agency (EEA), in the framework of the activities of the European Topic Centre for Air Pollution and Climate Change Mitigation.

The tool Transport Emissions Evaluation Models for Projects (TEEMP) was designed to evaluate CO2 and air pollutant emissions from transport projects using data gathered during project feasibility and actual operations. The tool was developed by CAI-Asia, ITDP and Cambridge Systematics for ADB transport projects and served as the basis for the Manual for calculating Greenhouse Gas Benefits of GEF projects, and has been applied to projects of ADB, ITDP and World Bank. A TEEMP-City tool is now also being developed for the city-wide analysis of multiple transport projects, supported by Veolia.

Project Design Document for the Delhi Metro Phase II CDM project.

World Bank designed ROADEO (Road Emissions Optimization), software for calculating GHG emissions at the planning, design, and construction phases, calculator user manual, and a report on GHG emissions generated by road construction and rehabilitation activities, which is classified by work categories and includes analysis of local and international best practices.

ALMEC. 2009. “Guidelines for Preliminary Estimations of Carbon Emissions Reduction in Urban Transport Projects.” Final report and calculators. May 2009. Series of Excel based calculators on BRT, Bio Diesel and Idling developed at request of the World Bank. 

The UNEP Risoe Tool for Selecting CDM Methodologies & Technologies –, gives an overview of the technologies used in CDM projects and the sectors (including transportation) where they are applicable as well as the methodologies and their applicability for every subtype.

Emission Reduction from Bus Rapid Transit and Pedestrian Improvements in Jakarta, Progress Report 2008 - 2010. Report produced by Pelangi as part of MoU with ITDP in which the applicability of CDM methodology AM0031 is reviewed for the Trans-Jakarta BRT.

Guidelines for Calculating GHG Benefits from Clean Technology Fund Investments in the Transport Sector. CTF co-financed operations in transport will be required to calculate GHG emissions reductions resulting from the investment. Annex 3 in this document summarizes the guidelines to be applied in CTF cofinanced operations.

Based on a case study in India ADB also published a report on measuring GHG emissions from road projects

The Ecological Transport Information Tool (EcoTransIT) calculates environmental impacts of any freight transport. Thereby it is possible to determine the energy consumption, CO2 and exhaust emissions transported by rail, road, ship and aircraft in any combination. EcoTransIT is free of charge for any non-commerical use.

UNEP has launched   a cleaner fleet management toolkit which evaluates the impact of vehicle fleets on environment, including climate change, and human health. It can also be used to develop and assess the impact of corrective actions.

IPCC Guidelines for National Greenhouse Gas Inventories, Chapter 3: Mobile Combustion.  This document describes the guidelines Non-Annex I Parties are expected to use for estimating and reporting their national GHG inventories.

IGES has been working closely with researchers at Nihon University in Tokyo, Japan and associated organizations in Thailand and the Philippines to develop such a tool. Mainstreaming a Transport Co-benefits Approach: A Guide to Evaluating Transport Projects represents the result of these efforts. The guidelines or TCG, provide a set of user-friendly, step-by-step instructions for policymakers, transport planners, and development specialists interested in quantifying co-benefits of transport projects in Asia.

CHANGER is the greenhouse gas calculator developed by the International Road Federation (IRF) specifically for road infrastructure projects. The tool is very flexible allowing estimation of GHG emissions for each of the construction operations performed or for the entire project. The results are expressed in tons of CO2 equivalent. A video presentation of CHANGER illustrating its main features is available on

Methodology for Determining GHG Emission Reductions Through Bicycle Sharing Projects. This methodology is applicable for project activities under the Verified Carbon Standard that reduce GHG emissions through the usage of public sharing-based bicycle projects which introduce an alternative mode of transportation to displace other, more carbon intensive modes.

Assessment of Greenhouse Gas Analysis Techniques for Transportation Projects. This report developed on behalf of American Association of State Highway and Transportation Officials (AASHTO) Standing Committee on Environment identifies a total of 17 tools or methods that can be used to analyze the GHG implications of transportation projects. Existing tools are categorized into three groups: (a) Transportation GHG calculation tools, (b) Transportation/emissions strategy analysis tools, and (c) Energy/economic forecasting tools.

Perspective on CO2. Detailed phased approach to calculate emissions from freight and logistics. (In Dutch). English summary available at

NTM. Online emission calculator for road, rail, sea and air  freight.

Methodology for Transport Energy Efficiency from Light Weight Pallets
This methodology outlines procedures to estimate the avoided net greenhouse gas (GHG) emissions resulting from project activities involving the use of pallets - the flat, portable structures that support goods during handling, transportation and storage - that are lighter in weight than their conventional alternatives for freight transport.
