The European Commission is expected to propose an amended emissions trading scheme (ETS) on July 15, reigniting a deep divide within European industry. Companies that have already invested heavily in low-carbon operations fear the overhaul could weaken the bloc's primary tool for curbing pollution from sectors like cement, steelmaking, and chemicals. In contrast, some chemicals and steelmaking giants are pushing for the scheme's relaxation, arguing that tighter constraints risk undermining their global competitiveness.

Under the current ETS, which has been operational since 2005, heavy industrial emitters must purchase permits for each tonne of carbon dioxide released. The upcoming revision is set to adjust the cap on emissions and the pace of free allowance phase-outs. While low-carbon investors warn that diluting the scheme would devalue their billions in green technology spending, traditional heavy polluters claim the transition timeline is too aggressive given current market conditions and technological readiness.

The debate centers on how quickly to tighten the supply of emissions allowances, which directly impacts compliance costs. Cement and chemical producers, facing stiff international competition from regions with laxer climate rules, argue that faster allowance reductions would drive production offshore without cutting global emissions. Meanwhile, early movers in green hydrogen and electric arc steelmaking contend that any backsliding would destroy the investment case for their low-carbon processes.

Geopolitical dynamics add another layer of complexity. European industry leaders point to the US Inflation Reduction Act's generous subsidies as a model, contrasting it with the EU's regulatory approach. Some member states, particularly those with heavy industrial bases, are lobbying for continued free allowances to protect jobs, while others insist the ETS must remain credible as the EU's climate flagship.

A counterargument holds that the ETS overhaul may have limited near-term impact on actual emissions reductions. Critics note that the current carbon price, already above €80 per tonne, has not yet driven transformative investment in hard-to-abate sectors like cement. They argue that without stronger incentives for demand-side shifts or carbon capture deployment, the scheme remains a cost signal without a guaranteed decarbonization mechanism.
