The AIR Index at airindex.com identifies the cleanest cars to give buyers confidence to switch to cleaner vehicles and restore the automotive industry badly impacted by the pandemic.
The freely available ratings database is the result of rigorous on-road testing according to the legal standard method, CWA17379.
It details real-world nitrogen oxide (NOx) and carbon dioxide (CO2) emissions – important pollutants that are measured to assess air quality and climate change.
It shows that clean and efficient vehicles, which have low NOx and low CO2 emissions already exist, without having to wait for new technology at scale.
As the world marks the 50th anniversary of Earth Day today, the AIR Index data can allow the revitalisation of the industry but also lock in the improved air quality that has been a result of the global lockdown.
Published by the AIR Alliance (AIR), the AIR Index demonstrates the risk of selecting vehicles based only on the official emissions figures that are not detailed enough to identify the cleanest cars.
A Euro 6 vehicle may be clean, or it may be dirty, but the official data do not give enough clarity to differentiate.
AIR is an open alliance of like-minded members. Any organisation, public or private, that shares its values and manifesto is encouraged to join.
Leading scientists have recognised the importance of the AIR Index and are urging car makers to utilise the figures in order to build cleaner vehicles.
