To the Editor:
Whether we're talking diesel or gasoline, the issue in Europe is more about old technology and higher emissions ("More black eyes for the diesel engine," autonews.com, Feb. 10).
Both Paris and London are now differentiating between old and new technology rather than full bans on diesel or any other technology.
We rely on the EPA, the California Air Resources Board and other agencies that are in charge of health-based air quality standards for all vehicle emissions -- not an automotive reporter -- as best-suited to determine whether there is a problem or not with diesel.
Rather than condemning diesel, those agencies recognize the improvements in emissions performance of new-generation clean diesel vehicles and their importance in meeting greenhouse gas emissions targets.
In January, the Health Effects Institute published the results of a multiyear research study looking at emissions performance and health effects of new-technology diesel engines; heavy-duty truck engines, to be exact. Laboratory animals exposed to those emissions for 30 months showed no significant effects: no lung cancer, no tumors.
Co-sponsored by the EPA, CARB and vehicle and engine manufacturers, the report speaks for itself.
Diesel Technology Forum
The forum is a nonprofit educational association representing diesel engine and vehicle manufacturers, suppliers and emissions-control technology manufacturers.
