Russia proposes carbon credits framework for SMRs

Russia's state nuclear corporation Rosatom has submitted a draft methodology to the UN's climate secretariat that would allow small modular reactors up to 300 MW to qualify for carbon credits under the Paris Agreement's Article 6.4 mechanism. The framework is design-agnostic and would cover both land-based and floating SMR units. Carbon credits, each representing one tonne of avoided greenhouse gas emissions, can be traded by states and organisations to meet climate goals. The IAEA projects up to 1,000 SMRs operating globally by 2060.

Where this fits

This move highlights the carbon legitimacy of nuclear as firm, dispatchable power. It also exposes a strategic vulnerability: Russia is leading the technical and diplomatic work to unlock climate finance for nuclear while Australia, which banned nuclear energy, remains sidelined from both the technology and the market frameworks being built around it. The methodology fight is part of the larger contest over which low-emission technologies will dominate the next 30 years and who will own the supply chains and the intellectual property that comes with them.

What it means

Australia cannot participate in or shape SMR climate mechanisms while its domestic nuclear ban remains in place. This leaves the country dependent on imported reactor designs, international carbon-credit frameworks it did not help negotiate, and competitive advantage that will accrue to nations that build their own SMR industries now. The firm, low-material alternative to the renewables-plus-gas path is not merely being foregone; it is being ceded to strategic competitors.
