EU member states have agreed in principle to begin measuring emissions from diesel-powered vehicles under actual on-the-road conditions.
But the EU has not yet agreed on when to begin the new system or what new emission targets might be set.
Real-world tests are widely expected to show considerably higher emission levels than carmakers achieve under today's officially sanctioned laboratory test methods, the Financial Times notes. Research by the International Council on Clean Transportation claims modern diesels emit at least seven times as much nitrogen dioxide, a smog-forming pollutant, as is indicated by current certification tests.
Industry trade group ACEA agrees with the concept of real-world tests. But is says any implementation plan should include ample time for carmakers to make the major hardware adjustments to improve diesel performance.
European cities are under pressure to improve their air quality. One expert at the Transport & Environment group in Brussels tells the FT that, without accurate emission measurements, cities "will have no choice but to ban diesels."
