First-mover disadvantage threatens EU decarbonisation momentum

The EU's Emissions Trading System has proven effective at driving aggregate emissions reductions, but it harbours a structural flaw that punishes companies moving fastest toward decarbonisation. Early adopters of expensive clean technologies face higher carbon costs than laggards still operating polluting assets, inverting the intended incentive structure. This dynamic threatens the investment pipeline needed to meet climate targets and undermines the credibility of carbon pricing as a policy lever.

The problem stems from how the ETS allocates allowances and benchmarks based on historical production patterns. A cement producer investing €50m in carbon capture equipment today will still compete for allowances against rivals using older, cheaper methods. The early mover absorbs capital costs upfront while the system provides no compensating advantage—worse, they may face stranded asset writedowns if market allowance prices remain depressed. This creates rational hesitation among capital-intensive industries to move ahead of peers, exactly when acceleration is needed.

Reform options under discussion include time-limited allowance bonuses for verified decarbonisation investments, dynamic benchmarking tied to best-available technology deployment timelines, and direct incentives for cross-border technology transfer. The economic case is straightforward: removing first-mover penalties would lower the total social cost of EU decarbonisation by encouraging competition to lead rather than follow. Without such reforms, the ETS risks becoming a system that optimises for lowest-cost emissions reductions in the short term while inadvertently delaying deeper, more structural industrial transformation.
