Scope:
The review assessed emissions compliance for diesel engines operating in Alberta, focusing on particulate matter (PM), nitrogen oxides (NOx), and greenhouse gas (GHG) emissions.
Key Findings:
- Regulatory Compliance:
Most engines met provincial standards under the Alberta Tier 4 guidelines, but older models required retrofitting to achieve compliance. - Emissions Reduction:
Upgrades, including diesel particulate filters (DPFs) and selective catalytic reduction (SCR) systems, achieved reductions of: - PM: Up to 85%
- Carbon Footprint:
Modern engines showed a 20% lower GHG output compared to pre-2006 models.
Recommendations:
- Retrofit or replace engines older than Tier 3 compliance.
- Implement advanced monitoring systems for real-time emissions tracking.
- Transition fleets to alternative fuels, such as biodiesel or renewable diesel, for further reductions.
Impact:
Adopting these measures aligns with Alberta’s environmental targets, ensuring sustainable operations and regulatory compliance.
