Difference between European and American emission standards?

Answer 1

In 2009, the single largest factor influencing the North American commercial vehicle market is the preparedness for supporting EPA 2010 emission-regulation-compliant trucks. Although EPA 2010-compliant trucks will not start putting pressure on the already stretched heavy-truck aftermarket, the time is opportune for the OES, independent repair facilities, and the aftermarket distribution chains to prepare for the permeation of these trucks in the North American heavy-truck population. This challenge is also offering tremendous revenue growth opportunities to the proactive market participants that are developing strategies and competencies to cater to the EPA-compliant trucks' demands for service and maintenance. On December 21, 2000, the Environmental Protection Agency (EPA) signed new emission regulations for model year 2007-and-later heavy-duty highway engines. The new regulations are widely referred to as EPA 2010 Regulations. On the basis of EPA 2004 and EPA 2007, EPA 2010 Regulations aim to reduce atmospheric pollution by significantly reducing nitrogen oxides (NOx), particulate matter (PM), and hydrocarbon (HC) emissions from diesel engine-powered heavy trucks. Chart 1 shows the drastic reduction in NOx and PM emission limits mandated by the EPA 2010 regulation.
