Cleaire, an innovator of diesel pollution controls closes

It’s a sad thing when a green tech company goes under, especially a company like Cleaire that kept its manufacturing domestic and provided high quality pollution controls for diesel engines.  According to a letter from the Air Resources Board to vehicle owners using Cleaire devices, the company closed on January 18th.

Like many others, Cleaire was a victim of the economic downturn.  In December 2010, when the air board slackened retrofit requirements for diesel trucks and other diesel engines in its rules, it was clear that retrofit manufacturers focused on the California market - like Cleaire was - would struggle.  Cleaire employed more than 100 people in what we would consider green collar jobs.

Let us not make this misfortune worse by allowing opportunist and factually-challenged rumors to run amok.  Diesel exhaust controls have been proven safe time and again. At least 20 other companies are selling California-verified diesel filters for a wide range of uses.  With all of those choices, there are no issues meeting compliance targets for California diesel rules.

California diesel rules will save thousands of lives and cut diesel fuel use by millions of gallons – enabling California to meet federal air quality standards, which ensures the state’s ability to keep critical federal funding. We need to stay on track with these diesel rules.

Please site your source of statistics regarding fuel savings and how you came to this conclusion. In my experience, through several revisions of emissions certification, fuel economy has been worsened. If there has been a reduction in fuel consumption it is more likely due to industry leaving the state of CA due to the excessive burden of over regulation and high cost of retrofitting diesel powered transportation that were previously certified and still met the emission certification that was in effect at time of manufacture. If I purchase a vehicle in 2000 that is certified by the EPA and CARB to be emissions compliant, is it economically and ethically reasonable to then require the vehicle to be brought to 2010 emissions compliance standards? I do support efforts to reduce emissions, however I do not support misleading the public, or what should be criminal regulating.

The biggest fuel savings from California diesel regulations come from idling limits. Other regulations that reduce fuel use include "SmartWay" efficiency standards for trucks and the shorepower measure for marine vessels. I posted more details on the benefits of California diesel regs a few years ago: http://switchboard.nrdc.org/blogs/dbailey/california_diesel_measures_a_l.html

The Air Resources Board has an area of their website called the Truck Stop that also has a lot of useful info: http://www.arb.ca.gov/msprog/truckstop/truckstop.htm

Our air quality resources are shared; everyone has to do their part to keep the air breathable and safe.

Thank you for your remarks on the loss of Cleaire. They were true innovators, attempting to protect public health from toxic diesel fumes while supporting our local economy. It is unfortunate that the CARB roll backs on retrofit requirements led to the end of this visionary company.
