Environment Canada (the environment ministry of the Canadian government) retained MathPro Inc. – in conjunction with John Clark Consulting (Toronto), Inc. – to conduct a quick response study to (1) identify available alternatives for Canadian refineries for timely compliance with Canada’s Sulfur in Gasoline Regulations and (2) estimate the benefits and costs of these alternatives to a specific sub-set of Canada’s refineries.

In the very short time available for this engagement, we (1) identified a set of prospective technical approaches that refineries could implement so as to meet the Regulations’ Interim Period and Long Term standards for sulfur in gasoline, (2) estimated the on-stream date for each alternative in each refinery, and (3) estimated the incremental refining costs and investment requirement for alternative in each refinery.

Results of the analysis informed negotiations between Environment Canada and the Canadian refining industry.
