Air Quality News: New database for carbuyers reveals vehicle pollution levels. “The AIR Alliance has created a database for car buyers that reveals the levels of nitrogen oxide (NOx) and carbon dioxide (CO2) emissions created by a particular vehicle. Covering hundreds of models, the AIR Index details vehicle emissions information and rates each from A (the best) to E (the worst). The database is the result of rigorous on-road testing according to the legal standard method, CWA17379.”
