Environment and Climate Change Canada (ECCC) recently published a discussion paper on “Driving effective carbon markets in Canada” (the Discussion Paper). The Discussion Paper sets out proposed changes to the federal benchmark criteria ahead of the federal government’s review next year. ECCC also launched consultations on the Discussion Paper, seeking comments and responses to questions included in the Discussion Paper from stakeholders.  This bulletin briefly summarizes the key topic areas, current requirements, the federal government’s proposal and considerations, and next steps set out in the Discussion Paper. Common scope of coverage Current requirement. The current benchmark requires that carbon pricing systems maintain a common scope, covering, at a minimum, an equivalent percent of combustion emissions as the federal backstop. It also requires market-based systems to cover industrial process emissions, and to limit eligibility for OBPSs, performance rebates, or the free allocation of allowances to sectors that are at risk of carbon leakage and competitiveness impacts of carbon pricing. Proposals and considerations. ECCC notes that the removal of the fuel charge (see our earlier bulletin here) requires rethinking how scope of coverage should work. The federal government is considering the following three options to modify the benchmark to specify the common scope criteria explicitly to ensure consistent minimum coverage across systems: Option 1: A threshold-based approach that would cover all facilities in specific sectors emitting above a certain level annually. Thresholds under consideration are 10kt per year (Option 1A) and 25kt per year (Option 1B). Option 1A would cover a large number of facilities and industrial activities, which would support market function and liquidity, but could create intra-sectoral competitiveness risks in some sectors. Option 1B would reduce these risks by covering fewer industrial activities where there is a significant split between emissions above and below the threshold, but may negatively impact market function…
