An Investigation into the Effects of Border Carbon Adjustments on the Canadian Economy Staff Working Paper 2023-27 Y.-H. Henry Chen, Hossein Hosseini, Craig Johnston, Sergey Paltsev, Marie-Christine Tremblay We examine the economic implications of border carbon adjustments (BCAs) for Canada. We find that, BCAs, in the form of import tariffs, reduce Canada’s carbon leakage and improve its competitiveness when Canada is part of a broad coalition of BCA-implementing countries. Welfare also improves when tariff revenues are transferred to households.
