The Ecoscore is an environmental indicator describing on a scale of 0 (worst) to 100 (best) how clean a vehicle is. The Ecoscore concept was already developed in the early noughties by a consortium including VITO and the VUB.



Running project

The Ecoscore is an environmental score indicating on a scale of 0 (worst) to 100 (best) how clean a vehicle is. The indicator takes into account both well-to-tank emissions (WTT, or all emissions originating from the exploitation, transport and distribution of the fuel until it’s in the fuel tank) and tank-to-wheel emissions (TTW, or all emissions originating from actually driving the vehicle). This adds up to well-to-wheel emissions (WTW). Consequently, the Ecoscore has a wider scope than most other environmental vehicle indicators. Another advantage of this indicator is that it is technology-neutral. This means that all drivetrains and fuel types are evaluated in an objective manner. As a result we are able to perform sustainability evaluations for a wide range of vehicles (cars, light commercial vehicles, heavy-duty vehicles, etc. and apply this in a large number of projects.

The website serves as a portal containing both data and background information on the Ecoscore project, and provides a link to some interesting tools. The aim of the website is to inform cities and citizens on clean vehicles and to guide them towards the cleaner choice. One important part of the website is the database on passenger cars, containing technical data and Ecoscores for all passenger cars sold in Belgium since the early nineties. This database is updated each two months. Other interesting features include the calculator (allowing visitors to individually calculate the Ecoscore for a (fictitious) vehicle), the ChassisTool (providing an Ecoscore based on the VIN or Chassis number of the car) and the FleetTool. This FleetTool is particularly aimed at cities or large companies that wish to have a better view on the environmental impacts of their fleet. Based on the inputs provided by the user, this fleet management tool calculates data regarding fuel consumption, CO2 emissions, Ecoscores, etc.,  both on individual vehicle and average fleet level.
