The Canadian Environmental Protection Agency (CEPA) and the US Environmental Protection Agency (EPA) on-road emission standards and limits of diesel emissions, reached their final phase in January 2010. This legislated that emissions of oxides of nitrogen (NOx) from on-road diesel engines be reduced to almost zero.
With the introduction of the final phase of diesel emissions standards for on-road vehicles by the Canadian and US Environmental Protection Agencies in January 2010, most engine manufacturers have chosen to use Selective Catalytic Reduction (SCR) technology. This technology allows vehicles to reduce the amount of emitted oxides of nitrogen (NOx) to almost zero.
The emissions standards for on-road vehicles, has been phased in over several years. In the coming years, the emissions standards for other diesel powered vehicle categories will come into effect, ensuring that all diesel vehicles are respecting the emissions levels legislated.
EMISSION REGULATIONS FOR ON-ROAD VEHICLES
In 2014 the CEPA and EPA will include off-road equipment in the reduction of emissions. This means that most mining, construction equipment, tractors and heavy-duty farming machines will need to use DEF in their day-to-day operations.
