The European Commission on July 17, 2026, proposed a sweeping revision to the EU Emissions Trading System (ETS) that slows the pace of emissions reductions, extends free carbon allowances for certain industries to 2038, and opens the door to international carbon offsets for EU industry starting in 2036 (Engadget, Reuters).

The ETS is the EU's primary tool for cutting greenhouse gas emissions. It works on a cap-and-trade principle: the EU sets an overall limit (cap) on how much carbon dioxide covered industries can emit, and companies buy or receive allowances that let them emit a corresponding amount. The cap shrinks each year, pushing emissions down over time. Companies that emit less than their allowance can sell the surplus to those that need more.

The Commission said the ETS review was prompted by "increased pressure" on EU industries due to changes in the geopolitical and economic context (Engadget). The proposal arrives after weeks of political maneuvering: ten EU countries including Italy and Poland urged the bloc on July 15 to reconsider a new carbon price on fuel, and the European Parliament's largest political group had already circulated a draft document on July 7 seeking to ease the carbon market burden on industry (Reuters, Reuters). The Commission faced competing calls from EU governments over whether to weaken the ETS at all before settling on its July 17 proposal (Reuters).

The core mechanics of the revision concern what regulators call the linear reduction factor (LRF) — the annual rate at which the emissions cap tightens. Under the previous framework, the LRF was set at 4.4 percent per year for the 2031–2035 period, on a trajectory that would have reached zero (full decarbonization of covered sectors) by 2039 (Engadget).

The revised proposal cuts that rate to 3.7 percent per year for 2031–2035, then drops it further to 1.7 percent per year after 2036. The post-2036 rate represents less than 39 percent of the pace that had been scheduled under the prior system. The cumulative effect: the ETS cap declines more slowly through the 2030s and at a dramatically reduced rate in the latter half of the decade (Engadget).

Two additional provisions expand industry flexibility under the revised system. Free carbon allowances for sectors covered by the Carbon Border Adjustment Mechanism (CBAM) — the EU's carbon border tax on certain imported goods — would be extended to 2038, rather than being phased out on the earlier timeline. Starting in 2036, the Commission would permit EU industry to purchase carbon offsets from outside the EU to count against their ETS obligations (Engadget).

Alongside the ETS revision, the Commission released an Electrification Action Plan (also referred to as the Energy Action Plan) intended to accelerate the transition from fossil fuels to green energy (Engadget). No further detail on the plan's specific measures was available in the source material.

The revision runs against the backdrop of binding legal commitments. The European Climate Law sets intermediate targets of reducing net greenhouse gas emissions by at least 55 percent by 2030 and by 90 percent by 2040, both relative to 1990 levels (European Commission). EU greenhouse gas emissions had decreased by 35 percent between 1990 and 2023 (Eurostat). The aviation sector under the ETS has already been moving in the opposite direction from the new proposal's industrial provisions: free allocation to aircraft operators was reduced by 25 percent in 2024 and by 50 percent in 2025, with full auctioning scheduled for 2026 (European Commission).

WWF responded to the proposal by stating it could not see how the EU would reach its legal climate targets under the revised ETS. The organization questioned how the Commission would compensate for the additional emissions allowed under the slower reduction trajectory while still meeting the 2040 target (Engadget, WWF).

The gap between the revised LRF trajectory and the 2040 target is the central tension here. A 90 percent net reduction from 1990 levels by 2040, with the ETS cap declining at 1.7 percent annually after 2036, leaves a mathematical gap that the Commission has not yet detailed how it intends to close. The offset provision and the electrification plan are the two mechanisms the Commission appears to be counting on, but neither has been specified in enough detail to assess whether they would bridge it.

For technology-intensive industries operating in the EU, the proposal offers material near-term relief. Data center operators, semiconductor manufacturers, and heavy industrial consumers of electricity have faced rising carbon costs under the ETS. Extending free allowances to 2038 and permitting international offset purchases lowers the effective carbon price for covered sectors. Whether that relief accelerates or delays capital deployment into lower-emission infrastructure is a question the proposal leaves open; the incentive structure now points in both directions simultaneously, with compliance costs reduced but the EU's longer-term decarbonization deadline unchanged.

This is a proposal, not a final regulation. It will require approval from the European Parliament and the Council of the EU, where the political pressures that shaped the Commission's draft will intensify rather than resolve. The competing calls from member states in the weeks preceding the proposal suggest the legislative process will be contested at every stage.
