More information, less emissions - estimating the real world CO2 emissions of passenger cars based on vehicle properties

Vehicle manufacturers are obliged to supply official fuel consumption data. However, legislation dictates that this fuel consumption must be measured over a standard test cycle, which has limited relation to real world driving and vehicle use. As a result, the official fuel consumption numbers severely underestimate real-world fuel consumption, and consequently real-world CO2 emissions (RWCO2). However, other aspects, such as idealized testing and administrative corrections, also play a role in this difference. In the interest of informing the consumer, the project ‘More Information Less Emissions – Empowering Consumers for a Greener 21st Century’ (MILE21,1 see also www.mile21.eu) aims to develop a platform via which drivers can investigate the fuel consumption and emissions of vehicles on the European market. Fuel consumption and CO2 emissions are directly related through the carbon content of the fuel. The initial model for RWCO2 emissions, Model M1, is dependent on vehicle properties. This initial model will be expanded at a later date, based on monitoring (Model M2) and consumer (Model M3) data.
