How Polluting is Your Old Vehicle?

SCRAP-IT

BC SCRAP-IT® PROGRAM

Consumers often ask the question, "How much cleaner is my new vehicle compared to my old one being scrapped?" This is an important issue for SCRAP-IT,® as we not only need to advise our consumers but we also need to estimate the smog reduction impact of all the vehicles being scrapped. In the summer of 2009, the AirCare® Research Centre agreed to assist SCRAP-IT® in answering this question. This Research Centre has the technical facilities to conduct detailed emission testing. Their emission tests follow the US EPA75 Test method and are equivalent to the tests used by vehicle manufacturers to certify their new vehicles meet government mandated emission standards. This test procedure allows for an "apples to apples" comparison of the emissions from old vehicles being scrapped vs. a new vehicle. SCRAP-IT® identified three families in the greater Vancouver area who had scrapped their old vehicle and who had purchased newer model vehicles. These families agreed to allow the Research Centre to test both their old and new vehicle. The US EPA75 Test is designed to measure the emission levels of various pollutants. The emissions performance comparison of the two key pollutants, hydrocarbons (HC) and nitrogen oxides (NOx), which are both precursors for photochemical smog, is shown in the charts below.
