Efforts to decarbonize long-haul trucking face literal uphill battle This article was originally published in BIV Magazine''s Trade issue. When it comes to decarbonizing the economy, pretty much everyone in the sustainable energy field agrees aviation and long-haul trucking will be the last mile on the road to net-zero by 2050. Of the on-road applications, long-haul trucking is probably the single most challenging, says Gordon McTaggart-Cowan, professor of sustainable energy engineering at Simon Fraser University. Transportation accounts for 25% of Canadas greenhouse gas (GHG) emissions, with heavy trucking accounting for 35% of that, or 9% of total national emissions. Globally, its estimated that heavy-duty trucking accounts for only 4% of the vehicles on the road, but 27% of road emissions. There are 60,000 heavy-duty trucks (vehicles that weigh at least 25 tonnes) registered in B.C. and 156,000 medium-duty trucks, according to the BC Trucking Association. They emit slightly more carbon dioxide (CO2) than the 2.2 million light-duty vehicles in B.C.
