However, this new EFT has not yet (as of 10 July 2017) been made available to the air quality community. Some of the emission factors for diesel cars and vans in COPERT 5.0 are higher than those incorporated in the currently available EFT v7.
Air Quality Consultants previously produced the CURED V2A spreadsheet tool (August 2016 version available here) to address the deficiencies of the EFT v7.
Air Quality Consultants has now carried out a high-level comparison of the CURED V2A tool against the emissions from COPERT 5.0 (available here). This shows, in broad terms, that CURED V2A still provides a robust sensitivity test of future vehicle emissions.
The continued use of CURED V2A will be further reviewed once Defra publishes its new EFT based on COPERT 5.0 emissions.
