2022 Reports 1 to 5 of the Commissioner of the Environment and Sustainable Development to the Parliament of Canada—Federal hydrogen strategy overestimates potential to reduce greenhouse gas emissions
2022 Reports 1 to 5 of the Commissioner of the Environment and Sustainable Development to the Parliament of CanadaFederal hydrogen strategy overestimates potential to reduce greenhouse gas emissions
Ottawa, 26 April 2022—A report released today by the Commissioner of the Environment and Sustainable Development Jerry V. DeMarco concludes that Natural Resources Canada’s strategy overestimated hydrogen’s potential to reduce greenhouse gas emissions because unrealistic assumptions were used. For example, the hydrogen strategy assumed a low price for electricity, the adoption of aggressive and sometimes nonexistent policies, and an ambitious uptake of new technology.
“The failure to appropriately project hydrogen’s impact on reducing greenhouse gas emissions could jeopardize Canada’s ability to meet its emission-reduction targets,” said Mr. DeMarco. “This is concerning because Canada’s greenhouse gas emissions have increased significantly since the United Nations Framework Convention on Climate Change was signed in 1992, making it the worst performer of all Group of 7G7 nations since that time.”
The audit found that Environment and Climate Change Canada estimated that the use of clean hydrogen technologies could produce the equivalent of a 15 megatonne reduction in emissions by 2030, while Natural Resources Canada estimated a contribution of up to 45 megatonnes in its ‘transformational’ scenario. The audit recommends that the federal government adopt a standard framework for estimating future emissions and that Environment and Climate Change Canada improve the quality and transparency of its climate change modelling and use reasonable, cost-effective, and technically feasible assumptions. If implemented, these recommendations will help improve Canada’s climate modelling in general, not just those aspects that relate to hydrogen.
“In our view, the assumptions in the federal hydrogen strategy are overly optimistic and compromise the credibility of the expected emission reductions,” said Mr. DeMarco. “If hydrogen is to be part of Canada’s plans to reduce greenhouse gas emissions, then Environment and Climate Change Canada and Natural Resources Canada will need to coordinate their approaches and more effectively model and communicate a pathway for hydrogen.”
