The Bureau de normalization du Québec (BNQ) and CSA Group have published the Joint Canada-U.S. National Standard CSA/ANSI R124/CAN/BNQ 1789-200 A harmonized methodology for reporting the production pathway and carbon intensity of H₂. This new standard establishes a harmonized methodology for H₂ producers, distributors and consumers to report on the production pathway and carbon intensity of H₂.

The current color-based system (e.g., blue/green/grey/pink) that is used to describe H₂ production, lacks clarity on the true impact and overall emission intensity of H₂ production. The new Joint Canada-U.S. National Standard CSA/ANSI R124/CAN/BNQ 1789-200 has been developed to define clear requirements for reporting the key characteristics that will support effective evaluation of the environmental impact of H₂ production.

The energy production sources used and the carbon emissions they produce are the primary focus of the standard's guidance for quantification. Further to carbon intensity, the new standard provides guidance for reporting of additional key characteristics, such as the nature of the feedstock, the geography of the supply chain, the source of energy and feedstocks, the quantity of water consumed and the country or region of origin.

This standard aims to facilitate the information sharing on H₂'s carbon intensity and its sources, hence helping producers provide data that can help users make informed procurement decision.

The BNQ acknowledges that this standard was funded by the Ministère de l'Économie, de l'Innovation et de l'Énergie (MEIE) du Québec and the Standards Council of Canada (SCC). CSA Group acknowledges that the development of this standard was also made possible, in part, by the financial support of Natural Resources Canada (NRCan).

"Québec has long been at the forefront of green energy. To maintain this edge, we need to keep exploring and developing low-carbon energy sectors, such as green H₂. Our government is therefore working to create the right framework and conditions for the sustainable development of this industry of the future, by supporting initiatives such as this new standard for measuring the environmental impact of H₂ production," said Christine Fréchette, Minister of Economy and Innovation and Minister Responsible for Regional Economic Development.

"Until now, the lack of a clear and consistent methodology limited the possibility of communicating the environmental impact of H₂ production. Thanks to this new standard, low-carbon H₂ producers now have a concrete tool to distinguish themselves on the market and increase their competitiveness. The standard also provides consumers with greater transparency regarding H₂ production methods, offering them clear information on its environmental impact," said Isabelle Landry, Principal Director, Bureau de normalization du Québec.

"Harmonizing H₂ production reporting across Canada and the U.S. is an important step toward a more transparent and sustainable energy sector. This new standard provides a science-based approach to measuring carbon intensity, helping producers and regulators align with market expectations and global sustainability goals. By establishing a common language for H₂ production, it supports informed decision-making and investment in low-carbon solutions," said Michael Leering, Director, Environment and Business Excellence, Standards, CSA Group.
