Bureau Veritas introduces green ammonia certification
Ammonia’s carbon intensity must be lower than 0.5 kg CO2eq/kg to receive “renewable ammonia certification”, Bureau Veritas said.

Ammonia produced from green hydrogen and airborne nitrogen emits no carbon dioxide (CO2) emissions. Combining it with low-emission pilot fuel will allow ships to operate with significantly lower emissions than fossil marine fuels. It can also be used as an inorganic carrier to transport and store green hydrogen safely over long distances.
In contrast, the majority of ammonia today has a high carbon footprint since it is produced using fossil natural gas. The International Energy Agency estimates that it accounts for 1.3% of global greenhouse gas emissions (GHG), Bureau Veritas reported.
Therefore, it is imperative to disclose the feedstocks being used and the emissions associated with ammonia production, Bureau Veritas clarified. Recently, industry non-profit Danish Shipping also called for consensus on what qualifies as "green" when shipping companies and operators bunker ships with green fuels like ammonia.
The green certification will ensure that ammonia is produced with green hydrogen rather than natural gas, Bureau Veritas explained. It will also provide “proof of bankability” for ammonia producers seeking initial investments.
Bureau Veritas said the hydrogen feedstock used for production must be certified as renewable to qualify for the renewable ammonia certification. In addition, hydrogen and ammonia must comply with "safety, sustainability, and renewable input" criteria and ammonia must have carbon intensity lower than 0.5 kg CO2eq/kg.
“This scheme is developed to provide a comprehensive assessment of plants producing ammonia with renewable hydrogen feedstock. It covers carbon footprint and other environmental impacts from a life cycle assessment perspective, incorporating safety and ESG aspects,” Laurence Boisramé, global director, hydrogen at Bureau Veritas said.
