While carbon offsets in agriculture can play a role in addressing climate change, they are not a perfect substitute for direct emission reductions. As shown in this paper through various arguments and case studies, climate policies in Canada have avoided the use of offsets to be sold in carbon markets, preferring instead to incentivize adoption of best management practices (BMPs) that provide environmental benefits along with climate mitigation benefits. We argue that this is a preferred policy option due to the perils and pitfalls inherent in the measurement and monitoring required to identify offset credits. While an appropriate approach might be to penalize Canadian farmers for any emissions their activities cause, this may do more harm than good. Canadian agricultural production is highly efficient and technologically advanced; therefore, reductions in Canada's contribution to the global food supply will result in less‐efficient production occurring elsewhere (i.e., leakage) that increases global greenhouse gas emissions.

Following Carter and Mérel (2016), we explore the export benefits of reforming supply management (SM) in Canada's dairy sector. A trade model with ten regions and five dairy product categories is developed and used to examine the potential benefits of opening international markets to Canadian dairy products. In addition to a baseline, three scenarios are compared—one with SM in place but with Canada able to export freely. Two other scenarios assume SM is eliminated and there is complete free trade, but with high‐ and low‐cost structures. Findings indicate that, in the high‐cost scenario, domestic consumers gain from lower prices as the domestic supply and exports fall compared to the status quo, but producers are less well off. However, under a low domestic cost structure, Canada becomes a major exporter of milk, with both producers and consumers gaining from free trade. This scenario assumes that domestic producers take advantage of economies of scale, enabling them to compete in international markets. Appropriate policies will be required to reform the quota regime, while minimizing the harm done to dairy farmers. [ABSTRACT FROM AUTHOR]
