A new industry report suggests construction companies can slash jobsite emissions by as much as 75 per cent using practical, near-term measures that do not compromise cost, timelines or performance.
Growing and Greening Canadian Construction draws on operational data from 617 projects across Canada and the United States, making it one of the most comprehensive analyses of construction-related emissions to date. The report was developed through a collaboration of major general contractors, including PCL Construction, in partnership with Transition Accelerator.
Focusing specifically on emissions generated during jobsite activities, the report identifies where emissions are concentrated and outlines practical steps to reduce them using technologies and approaches already available in the market.
“The report uses real-world project data to identify where emissions are generated on jobsites and where the most effective reduction opportunities exist,” said Anton Pojasok, head of sustainability for PCL Construction. “Because the data is aligned to how construction projects are actually delivered, versus relying on theoretical models, these are steps construction teams can implement right away.”
Five-step roadmap
The report lays out a five-part roadmap that balances technical feasibility with economic and operational realities, including equipment turnover cycles and typical infrastructure timelines.
Among the most impactful measures is the electrification of light-duty vehicles and small equipment. With electric alternatives already widely available and cost-effective, this step alone could reduce total jobsite emissions by up to 15 per cent by eliminating gasoline use and cutting diesel consumption.
Heating systems—particularly in cold climates—also present a major opportunity. Improving efficiency and shifting to electric or lower-emission options could reduce emissions by up to 10 per cent while also lowering fuel costs and improving worker comfort.
Another key recommendation is connecting projects to grid power wherever possible, instead of relying on diesel generators. This shift can cut emissions by up to 15 per cent and reduce noise and operating costs, especially on long-duration or remote projects.
For heavy equipment, where full electrification remains limited, the report points to renewable diesel as an immediate solution. It can deliver lifecycle emissions reductions of 40 to 80 per cent per litre and lower total project emissions by as much as 25 per cent.
Finally, introducing hybrid and electric excavation equipment can reduce emissions by up to 10 per cent while helping contractors gain experience with emerging technologies.
Industry-wide effort needed
The report stresses that achieving meaningful reductions will require coordinated action across the construction value chain, including contractors, equipment manufacturers, utilities, fuel suppliers and governments.
By aligning efforts, the industry can accelerate adoption of low-emission technologies, reduce implementation barriers and support broader climate and infrastructure goals.
“Decarbonization should not only be viewed as a compliance exercise, but as a strategic opportunity to strengthen competitiveness, improve project performance and support long-term industry growth,” Pojasok said.
