Europe is in the midst of a major expansion of its carbon pricing architecture. Building on the success of the original Emissions Trading System (ETS1), the EU is introducing ETS2 — a new carbon market designed to put a price on CO₂ emissions from sectors that previously had little or no exposure to carbon costs.
Unlike the existing ETS, which covers large industrial sites and power generation, ETS2 brings fuel combustion emissions from road transport, buildings, and other smaller energy users into a regulated carbon pricing framework. This represents one of the most significant policy shifts in how Europe manages emissions from everyday energy use
How ETS2 Works
Under ETS2, fuel suppliers must purchase and surrender allowances based on the CO₂ emissions generated when their fuels are used. Each allowance equals 1 tonne of CO2 equivalent.
Over time, the emissions cap will tighten — reducing the number of available allowances and reinforcing the carbon price signal.
In practice, this means:
The overall emissions cap is set to decline steadily over time, in line with the EU’s broader climate ambition to reduce greenhouse gas emissions by at least 55% by 2030 compared with 1990 levels. This tightening cap will progressively reduce the number of available allowances, putting upward pressure on carbon costs.
Why This Matters for Fuel Markets
ETS2 changes the economics of fossil fuels.
If allowance prices rise, the cost of supplying high-carbon fuels rises with them. That shifts attention toward fuels with lower lifecycle emissions, not just for climate reasons, but for cost control.
For fuel suppliers, carbon intensity is no longer just a sustainability metric. It becomes a financial variable.
Where Biomethane Comes In
Biomethane is upgraded biogas produced from organic waste and agricultural residues. When certified under EU sustainability standards, it can be treated as zero-emission under ETS2.
That means:
As the emissions cap declines over time, the cost implications of fuel carbon intensity become increasingly relevant.
Biomethane therefore represents not only a decarbonisation pathway, but also a tool for managing compliance exposure.
The Bigger Picture
EU ETS2 marks a considerable expansion of Europe’s carbon market. By extending pricing into road transport and buildings, it brings fuel-related emissions into mainstream climate regulation. In this new environment, the ability to source and deploy certified low-carbon fuels such as biomethane will be increasingly crucial for compliance planning and cost optimisation.
