NOx warning for Local Authorities

    Local authorities bidding for the Department for Transport’s 5m Clean Vehicle Technology funding may fall into the NOx trap, warns real-world emissions measurement specialist Emissions Analytics.

    Local authorities are required to document how they will monitor and evaluate real-world emissions.

    EU regulations for NOx and mpg are calculated using the New European Drive Cycle test, providing theoretical emissions figures for each vehicle.

    Now, Emissions Analytics is developing a new traffic simulation model that will calculate the effect of speed and congestion on fuel economy, as well as CO2, NOx and CO components. Underpinned by the data from its real-world tests, this simulation helps local authorities select the best vehicles.
