A new Environment Canada study shows that trucks are more environmentally friendly than railway locomotives, says the Canadian Trucking Alliance.

The CTA says that the scientific evidence in the report helps continues to dispel the negative myths surrounding the impact of trucks on the environment.
This latest study, entitled Trucks and Air Emissions, shows that on a per unit basis, truck emission rates are lower than locomotive emission rates for particulate matter (PM) and nitrous oxides (NOx). The study also found that trucks have reduced their emissions by over 80% since the 1970s, decreased their fuel consumption rate by 50%, and increased their payload efficiency by 300%.
The CTA also says that about 50% of Canadian long-haul trucking fleets are made up of trucks less than 4 years old. Trucks operating in other industries are generally found to be older and more of a burden on the environment. For example, 90% of the trucks used in the farming industry are 10 years or older, the CTA says.
