In the MOU, the Smith government agreed to work with the Liberal government towards long-term effective carbon prices in Alberta.Now, based on some new net zero modelling from the Canada Energy Regulator (CER), as contained in the 2026 Canada’s Energy Future (CEF) report, I estimate that Alberta’s carbon tax could reach $550 (2025 dollars) per tonne by 2050 to achieve net zero emissions in the province. .This $550 Alberta carbon tax could create uncertainty for nearly $200 billion in private sector investment in carbon capture, utilization and storage (CCUS), oil sands expansion and optimization projects, and pipeline development in the province.Obviously, there needs to be far greater scrutiny of the economic and fiscal consequences of Premier Smith’s commitment to reach Alberta NZE 2050. Yet, the Alberta government still has not publicly shared any detailed economic and fiscal impact analyses of the costs of pursuing Alberta NZE 2050, even after the numerous requests I have filed over the past two years, through the Access to Information Act. Just what are they hiding from Albertans?The Smith government should immediately release the results of all its carbon policy modelling, including the Alberta carbon tax price path to reach Alberta NZE 2050, and the implications of a rising Alberta carbon tax price on the competitiveness of large emitter sectors, such as Alberta’s oil sands sector.So, when the agreement on the “made-in-Alberta” carbon tax is signed, don’t just focus on the carbon tax sticker price in 2030, but also focus on the long-term Alberta carbon tax sticker price path towards the Smith government’s ultimate goal of a net-zero Alberta by 2050.Lennie Kaplan was a senior manager in the fiscal and economic policy division of the Ministry of Treasury Board and Finance, where he worked on the development of energy and environment policy. He also served as a consultant to the Office of the Auditor General during its 2018 audit, “Design of Systems to Manage the Climate Leadership Plan and Adaptation.” In 2019, he provided initial policy advice to the Alberta government leading to the development of the Technology Innovation and Emissions Reductions (TIER) regime.
