The Argument
"Carbon pricing is driving up food prices"
The claim: commercial carbon pricing on freight, processing, and farm inputs trickles through the supply chain and significantly raises grocery costs.
$ The Reality

Carbon pricing as % of food cost
0.3%
ⓘ How the pass-through works
Commercial carbon pricing at $95\u2013$110/t adds costs at each stage of the food supply chain: trucking fuel, food processing energy, cold storage electricity, and farm inputs. But at each step the carbon cost is diluted across massive volumes of product. A $0.02 fuel surcharge spread across 40,000 lbs of freight adds fractions of a cent per item.
Food prices rose ~21% from 2020-2024. Every driver in this analysis is traceable to a specific StatCan table, public corporate filing, or calculable from published carbon pricing rates. Carbon pricing's contribution is the only one that can be calculated from first principles — making it the most precisely measurable and the smallest.
