The European Commission has unveiled a comprehensive review of the European Union Emissions Trading System (EU ETS), signaling a strategic pivot in the bloc’s flagship climate policy to better align environmental goals with industrial survival. The proposed reforms introduce a dual-track approach: providing immediate breathing room for energy-intensive industries through a moderated pace of emissions cap reductions and extended free permit allocations, while simultaneously mobilizing hundreds of billions of euros in new capital to accelerate the transition to clean technology. By adjusting the trajectory of the carbon market and integrating domestic carbon removals for the first time, the Commission aims to safeguard the European industrial base against high energy prices and geopolitical instability without abandoning its legally binding commitment to reach climate neutrality by 2050.
Evolution of the EU Emissions Trading System: A Historical Perspective
To understand the magnitude of the proposed changes, it is essential to examine the history and performance of the EU ETS. Launched in 2005, the system was the world’s first major carbon market and remains the cornerstone of EU climate policy. It operates on a "cap-and-trade" principle, where a ceiling is set on the total amount of certain greenhouse gases that can be emitted by the installations covered by the system. Within the cap, companies receive or buy emission allowances, which they can trade with one another as needed.
Over the past two decades, the ETS has expanded to cover approximately 40% of the EU’s total greenhouse gas emissions, specifically targeting energy-intensive sectors such as power generation, oil refining, steel, cement, paper, and chemicals. Since its inception, the system has been remarkably effective in its primary objective; the Commission reports that emissions in the covered sectors have fallen by 50% compared to 2005 levels. Furthermore, the auctioning of allowances has generated over €270 billion in revenue, which has been funneled back into climate-related projects and social support measures across Member States.
However, the landscape changed dramatically following the Russian invasion of Ukraine and subsequent tensions in the Middle East. These geopolitical shifts triggered a massive surge in energy costs, placing European manufacturers at a disadvantage compared to global competitors in regions with lower carbon costs or cheaper energy. This economic pressure led to calls from several Member State governments and industrial lobbies to "modernize" the ETS, ensuring it does not inadvertently lead to deindustrialization—a phenomenon known as carbon leakage, where production moves to countries with laxer environmental regulations.
Strategic Adjustments to the Linear Reduction Factor
One of the most significant technical changes in the review concerns the Linear Reduction Factor (LRF). The LRF is the annual percentage by which the total cap on emissions is reduced. Under previous agreements, the LRF was set at 4.3%, with a planned increase to 4.4% for the 2028–2030 period.
In a move to provide "relief" to industry, the Commission now proposes a more gradual reduction path for the next decade. The new proposal sets the LRF at 3.7% for the period between 2031 and 2035, followed by a further easing to 1.7% starting in 2036. While this appears to be a deceleration of climate ambition, the Commission maintains that this trajectory is scientifically aligned with the EU’s 2040 target of a 90% net reduction in emissions compared to 1990 levels. By spreading the reduction burden over a longer timeframe, the Commission hopes to prevent sudden price spikes in carbon allowances that could bankrupt marginal industrial players.
Extension of Free Allocations and the CBAM Linkage
The proposal also addresses the contentious issue of free allowances. Historically, the EU has granted free permits to sectors at high risk of carbon leakage. With the introduction of the Carbon Border Adjustment Mechanism (CBAM)—a tariff on carbon-intensive imports—the EU had planned to phase out these free allowances rapidly to comply with World Trade Organization (WTO) rules against double protection.
However, the new review proposes a significant delay in this phase-out. For sectors covered by CBAM, the Commission suggests slowing the transition, allowing free allocations to persist until 2038. Furthermore, the issuance of these allowances will now extend well into the 2040s. This extension is not a "blank check" for polluters; rather, it is part of a "quid pro quo" strategy. To remain eligible for free permits, companies must develop "Invest in EU Decarbonisation Plans." Operators will be required to invest an amount equivalent to 100% of the financial value of their free allowances into domestic decarbonization projects, ensuring that the "saved" costs are directly recycled into green technology.
Integrating Carbon Removals: A New Market Frontier
In a landmark shift for carbon market design, the Commission has proposed the integration of permanent domestic carbon removals into the ETS. This move targets the "hard-to-abate" sectors—such as heavy industry and certain chemical processes—where zero emissions are currently technically or economically unfeasible.
The proposal includes a mechanism to integrate 250 million tonnes of high-quality, certified permanent removals. The Commission would have the authority to purchase these removals and subsequently increase the ETS cap by an equivalent amount. This serves two purposes: it provides a "safety valve" for the market by increasing the supply of allowances when needed, and it creates a guaranteed demand for the nascent carbon removal industry. By establishing a price signal for removals within the ETS, the EU aims to kickstart investment in technologies like Direct Air Capture (DAC) and Bioenergy with Carbon Capture and Storage (BECCS).
The Industrial Decarbonisation Bank and Financial Support
To facilitate the massive capital expenditures required for industrial transformation, the Commission has proposed the creation of the Industrial Decarbonisation Bank (IDB). This institution is envisioned to make up to €100 billion available for supporting the production of clean technologies and the decarbonization of existing industrial assets.
The rollout of the IDB will be preceded by the "ETS Investment Booster," a first-phase initiative estimated at €30 billion. This booster is designed to reward early movers—companies that take the risk of investing in breakthrough technologies before they are commercially proven. Additionally, the review introduces a strict mandate for Member States: they must now spend at least 50% of their national ETS auction revenues specifically on industrial decarbonization within the ETS sectors, a move intended to prevent carbon revenues from being used to plug general national budget deficits.
Expansion to Aviation, Maritime, and Waste Sectors
The review does not focus solely on heavy industry; it also significantly expands the scope of the ETS to other polluting sectors:
- Aviation: The scope will be extended to include all departing international flights to destinations within a 5,000 km radius. Crucially, the system will now cover all incoming and departing flights by business jets, addressing long-standing criticisms regarding the exemptions granted to private aviation.
- Maritime: The ETS will be expanded to include smaller vessel categories that were previously exempt, ensuring a more level playing field in the shipping industry.
- Waste Incineration: For the first time, the waste incineration sector will be fully integrated into the ETS, incentivizing better waste sorting and the adoption of carbon capture technologies at incineration plants.
To support these transitions, the Commission will dedicate direct funding for the uptake of sustainable aviation fuels (SAF), maritime fuels, and the development of a hydrogen economy.
Official Reactions and Global Context
Wopke Hoekstra, the European Commissioner for Climate, Net Zero, and Clean Growth, emphasized that the review is about ensuring the ETS remains a "genuine engine for innovation." In his statement, Hoekstra noted, "The EU ETS has proven that carbon pricing works. It has cut emissions, strengthened Europe’s energy security, and mobilized investment. Today’s proposal brings together three key goals: climate action, competitiveness, and independence."
While the Commission frames the proposal as a balanced "middle way," it is expected to face intense scrutiny. Environmental advocacy groups have expressed preliminary concerns that slowing the LRF and extending free allocations could dampen the price signal needed to drive rapid change. Conversely, industry groups, while welcoming the financial support of the IDB, remain wary of the new conditionality requirements tied to free permits.
Analysis of Implications and Next Steps
The proposed ETS review represents a sophisticated attempt to navigate the "Green Paradox"—the challenge of maintaining high environmental standards while preventing the flight of capital and industry to less regulated markets. By slowing the pace of the cap reduction, the EU is acknowledging that the "stick" of high carbon prices must be accompanied by a much larger "carrot" of financial subsidies and investment certainty.
The integration of carbon removals is perhaps the most forward-looking aspect of the proposal. It signals that the EU views the 2040s not just as a period of reduction, but as a period of active atmospheric restoration. If successful, this could make the EU a global leader in the carbon removal services market.
The legislative journey for this proposal is just beginning. It will now be submitted to the European Parliament and the Council of the EU. Given the economic stakes, the negotiations are expected to be protracted, with Member States likely to clash over the distribution of IDB funds and the specific timelines for the CBAM phase-in. A final legislative text is not expected until well into next year, but the direction of travel is clear: the EU is doubling down on carbon pricing, but with a new emphasis on industrial protectionism and massive state-led investment.
