B.C. Study Uses Remote Sensing to Measure Truck Emissions

Matt Ball on April 15, 2013 - in Transportation

An in-depth report commissioned by Metro Vancouver has been conducted to determine how dirty – or not – the province’s truck fleet is. The study was conducted using remote emissions sensing at 26 locations throughout the Lower Fraser Valley over a 55-day period between July and October 2012. Envirotest Canada set up remote sensing devices at roadside sites, weigh scales and brake check points, which use infrared technology to measure the output of hydrocarbons, NOx, particulate matter and carbon monoxide from heavy-duty trucks as they pass through an infrared beam. Emissions from a total of 11,700 heavy vehicles were read, and then traced back to a specific make and model year using the province’s registration database.

The study found that the emissions standards implemented by the US Environmental Protection Agency (EPA) and adopted by Canada, have been effective in drastically reducing PM and NOx.
