COP28 | New declaration calls for green hydrogen to be prioritised for fossil-fuel replacement, not heating or power
Pledge is a direct response to a rival declaration accused of muddying the waters for clean H2 standards

The Joint-Agreement on the Responsible Deployment of Renewables-Based Hydrogen saw 59 endorsements, with less than a third from companies involved in hydrogen projects, including ACWA Power, ArcelorMittal, H2 Green Steel, CWP, and ReNew Power.
Only two governments are listed among the signatories — Panama and the national government of Scotland, but not the United Kingdom — as well as Oman’s government-founded auction service Hydrom and the UN-backed Race to Zero campaign.
The rest of the signatures come from NGOs, environmental non-profit organisations, trade associations and voluntary certification companies such as the Green Hydrogen Organisation.
These include, but are not limited to: fertilisers, methanol, chemicals, direct-reduced iron, fuels for shipping and aviation, seasonal electricity storage “when renewable supply to the grid is [greater than] 100%”, and “some very limited segments” of heavy-duty trucking or off-road mobility.
The declaration also highlights “most use cases related to residential & commercial heating and power generation” as potentially cannibalising renewable electricity and preventing a full transition away from fossil fuels.
The signatories also pledge to independently monitor and verify that green hydrogen is in fact produced from renewable electricity sources and not driving an increase in fossil fuel generation on the power grid where projects are located.
“Additionally, we encourage the consideration of embodied or embedded emissions when accurately reporting the net impact on emissions of hydrogen deployment,” the joint agreement adds.
The signatories also pledge to work towards regional and internal harmonisation of certification schemes “in alignment with the above emissions accounting methodology”.
Community benefits
The joint agreement also calls for developers to ensure community benefits and minimal environmental impacts from their green hydrogen projects.
In addition to “a net-positive impact” on biodiversity at sites, the signatories pledge to “prioritise non-freshwater sources for all required volumes of ultrapure, cooling, and raw water usage — if and only if desalination ensures proper dissemination of the resulting brine to avoid damage to salt-water environments and fish populations”.
Similarly, the agreement includes a pledge to allocate a portion of renewable energy and desalinated water to the local community, as well as practicing “sustainable water management practices” in water-stressed regions.
The signatories also agree to “actively involve all impacted communities in an accessible manner, in their respective local languages, and with full disclosure of information”, in order to ensure consent from indigenous and local communities throughout the development and lifecycle of projects.
