International Council on Clean Transportation (ICCT) roadmap model
The International Council on Clean Transportation (ICCT) roadmap model is an Excel-based tool designed to help policymakers worldwide to identify and understand trends in the transportation sector, assess emission impacts of different policy options, and frame plans to effectively reduce emissions of both greenhouse gases (GHGs) and local air pollutants.
It is designed to allow transparent, customizable estimation of transportation emissions for a broad range of policy cases. The Roadmap model estimates changes in actual transportation activity by country and region based on changes in forecasts of population, Gross Domestic Product (GDP), and relative fuel prices.
An annual data update and validation process is conducted to ensure the use of best available data sources and methods.
Key questions addressed:
- What are different policy effects on well to wheels (WTW) GHG and non-GHG emissions?
Sample data inputs:
- Forecasted changes in population, gross domestic product, and relative fuel prices
Sample quantitative outputs:
- Projected vehicle emissions factors
- Emissions of GHGs and local air pollutants
- Health impacts
