The European Commission has officially unveiled its highly anticipated review of the European Union Emissions Trading System (EU ETS), signaling a major recalibration of the bloc’s primary tool for combating climate change. The proposed reforms aim to navigate a complex path between maintaining the EU’s global leadership in decarbonization and ensuring the economic survival of its heavy industries in an era of volatile energy prices and intensifying global competition. By proposing a slowdown in the pace of mandatory emissions reductions and extending the duration of free carbon allowances, the Commission is offering a "soft landing" for industrial sectors while simultaneously mobilizing hundreds of billions of euros to fund the transition to clean technology.
The Evolution and Impact of the EU Carbon Market
Since its inception in 2005, the EU Emissions Trading System has functioned as the cornerstone of European climate policy. Operating on a "cap and trade" principle, the system sets a limit on the total amount of greenhouse gases that can be emitted by specific sectors, including power generation, oil refining, steel, cement, paper, chemicals, and commercial aviation. Within this cap, companies receive or buy emission allowances, which they can trade with one another as needed.
The historical performance of the ETS has been a point of pride for Brussels. Over the last two decades, the system has been credited with driving a 50% reduction in emissions within the covered sectors. Furthermore, it has generated more than €270 billion in revenues, which have been largely reinvested into climate-related projects across Member States. However, as the EU moves toward its ambitious "Fit for 55" goals—aiming for a 55% net reduction in emissions by 2030—the pressure on the industrial sector has reached a breaking point, necessitating this comprehensive review.
Calibrating the Linear Reduction Factor for a Managed Transition
One of the most significant technical shifts in the new proposal involves the adjustment of the Linear Reduction Factor (LRF). The LRF is the mechanism that dictates the annual percentage by which the total emissions cap is reduced. Currently set at 4.3%, with a planned increase to 4.4% between 2028 and 2030, the Commission now proposes a more gradual trajectory for the following decade.
Under the new plan, the LRF would be adjusted to 3.7% for the period of 2031 to 2035, before dropping significantly to 1.7% from 2036 onward. The Commission maintains that this revised path is still strictly aligned with the EU’s 2040 climate target of a 90% reduction compared to 1990 levels and the ultimate goal of climate neutrality by 2050. By slowing the reduction pace in the mid-2030s, the Commission intends to provide industries with the necessary "breathing room" to deploy capital-intensive technologies that are currently in the pilot or early-adoption phases.
Extending Free Allowances and the Link to CBAM
To protect the competitiveness of European firms against international rivals who do not face similar carbon costs—a phenomenon known as "carbon leakage"—the EU has historically provided a portion of allowances for free. These are allocated based on benchmarks that reward the most efficient installations in each sector.
The new proposal extends the issuance of these allowances well into the 2040s, a move that provides long-term regulatory certainty for industrial giants. Crucially, the Commission has proposed slowing the phase-out of free allocations for sectors covered by the Carbon Border Adjustment Mechanism (CBAM). This includes industries such as steel, aluminum, and fertilizers. Originally slated for a faster transition, the phase-out will now be extended until 2038.
However, this relief comes with stringent conditions. The Commission has introduced a "quid pro quo" model: free allocation will become conditional upon operators developing "Invest in EU Decarbonisation Plans." Companies must demonstrate that they are investing an amount equivalent to 100% of the value of their free allowances into decarbonization projects within the European Union. This ensures that the financial relief provided by the state is directly funneled into the green transition rather than absorbed into corporate profits.
Financing the Transition: The Industrial Decarbonisation Bank
Recognizing that regulatory relief alone is insufficient to trigger the massive shift required, the Commission has proposed the establishment of an "Industrial Decarbonisation Bank" (IDB). This new financial institution is intended to make up to €100 billion available to support investments in industrial decarbonization and the production of clean technologies, such as green hydrogen, carbon capture, and sustainable manufacturing processes.
To provide immediate momentum, the Commission will launch the "ETS Investment Booster," which serves as Phase I of the IDB. This booster is expected to deploy approximately €30 billion to reward companies that take early, decisive action in reducing their carbon footprint. This proactive funding strategy is widely seen as Europe’s response to the United States’ Inflation Reduction Act (IRA), which has drawn significant green investment away from Europe through lucrative tax credits and subsidies.
In addition to the IDB, the proposal mandates that Member States must spend at least 50% of their national ETS revenues on investments specifically targeted at decarbonizing the sectors covered by the system. This creates a closed-loop financial ecosystem where the costs paid by polluters are used to fund the technology that will eventually eliminate their need to pollute.
Integrating Carbon Removals into the ETS Framework
In a move that could transform the nascent carbon removal industry, the Commission’s review proposes the integration of 250 million tonnes of permanent domestic carbon removals into the ETS. This mechanism would allow the Commission to purchase certified removals—such as those generated by Direct Air Capture (DAC) or Bioenergy with Carbon Capture and Storage (BECCS)—and increase the ETS cap by an equivalent amount of allowances.
This integration serves two purposes. First, it provides a much-needed demand signal for the carbon removal market, helping to lower the costs of these expensive technologies through economies of scale. Second, it provides additional flexibility for "hard-to-abate" sectors—such as heavy chemicals or long-haul shipping—where total decarbonization is currently technically or economically unfeasible. By allowing high-quality removals to offset residual emissions, the EU can maintain its net-zero trajectory without forcing the total closure of essential industrial plants.
Expanding the Scope: Aviation, Maritime, and Waste
The review also addresses sectors that have previously enjoyed exemptions or limited exposure to carbon pricing. In the aviation sector, the Commission proposes extending the ETS scope to include all departing international flights to destinations within 5,000 kilometers of the EU. Furthermore, business jets—often criticized for their high per-passenger emissions—will now be fully integrated into the system for both incoming and departing flights.
The maritime sector will see its coverage expanded to include smaller vessels that were previously exempt. To support these transitions, the Commission has earmarked direct financial support for the uptake of sustainable aviation fuels (SAF), maritime biofuels, and hydrogen-based propulsion systems.
Perhaps most notably, the proposal extends the ETS to include the waste incineration sector. This move is designed to encourage better waste sorting and recycling, as the cost of burning non-recyclable waste will now include a carbon price, making circular economy practices more economically attractive.
Geopolitical Context and Official Responses
The timing of this review is heavily influenced by the geopolitical shifts of the last three years. The energy crisis triggered by the Russia-Ukraine conflict and subsequent tensions in the Middle East have driven European energy prices to record highs, placing an immense burden on energy-intensive industries. EU Commission President Ursula von der Leyen had previously pledged to modernize the ETS to make it "more flexible" in response to these pressures.
Wopke Hoekstra, the Commissioner for Climate, Net Zero and Clean Growth, emphasized the dual nature of the proposal during its unveiling. "The EU ETS has proven that carbon pricing works," Hoekstra stated. "It has cut emissions, strengthened Europe’s energy security, and mobilized investment across our economy. Today’s proposal brings together three key goals: climate action, competitiveness, and independence. It transforms the ETS into a genuine engine for innovation."
Analysis of Implications and Next Steps
The Commission’s proposal represents a pragmatic shift in European climate policy. By slowing the LRF and extending free allowances, Brussels is acknowledging that the "stick" of carbon pricing must be balanced with a more substantial "carrot" of financial support and regulatory flexibility.
For industry, the proposal provides a clearer, albeit still challenging, roadmap for the next two decades. The conditionality of free allowances ensures that the European industrial base will either modernize or face increasing financial penalties. For the global carbon market, the inclusion of removals and the expansion of the ETS scope reinforce the system’s position as the world’s most sophisticated carbon pricing mechanism.
The legislative journey for these proposals is only beginning. The text will now be submitted to the European Parliament and the Council of the European Union. Both bodies will develop their respective positions, likely leading to months of intense negotiations. Industrial lobby groups are expected to push for even slower phase-outs of free allowances, while environmental NGOs may voice concerns that slowing the LRF could jeopardize the EU’s 2040 climate integrity.
The final legislative text, once adopted, will define the economic landscape of the European Union for the next quarter-century, determining whether the bloc can successfully pioneer a model of "competitive decarbonization" that the rest of the world can follow.
