The European Union Emissions Trading System (EU ETS) remains the cornerstone of Europe’s climate policy, placing a price on carbon emissions for power generators and heavy industry. As we progress through 2025, the market is undergoing significant shifts that will directly influence carbon costs and require businesses to adopt more strategic management approaches.

The EU ETS: A Powerful Decarbonisation Tool

The EU ETS operates on a cap-and-trade principle, setting an overall limit on the amount of greenhouse gases that can be emitted by participating installations. Within this cap, companies buy and sell emission allowances (EUAs) as required. This market-based mechanism incentivises businesses to reduce emissions, invest in cleaner technologies, and ultimately contribute to the EU’s ambitious climate objectives.

As of 2025, the price of carbon allowances within the EU ETS typically ranges between €65 and €75 per tonne. This robust price level underscores the EU’s commitment to decarbonisation and provides a clear economic signal to drive emissions reductions.

Key Factors Driving Market Tightening in 2025

A series of policy measures are set to tighten the EU ETS market, shaping EUA prices and heightening the need for proactive carbon management:

• Market Stability Reserve (MSR) Reductions: The MSR is designed to manage the surplus of allowances. Between September 2025 and August 2026, auction volumes will be reduced by 276 million allowances. This follows the invalidation of 270.5 million allowances on 1 January 2025. These deliberate contractions in supply are expected to push carbon prices upward.
• Cessation of Frontloaded Auctions: From August 2026 onwards, the market will tighten further due to the end of frontloaded auctions, reducing the availability of allowances in advance and constraining supply.
• Stricter Emissions Caps: The EU’s 2030 target of at least a 55% reduction in net greenhouse gas emissions compared with 1990 levels, alongside the proposed 90% reduction by 2040, ensures that caps will continue to become more stringent over time. This long-term policy trajectory reinforces the scarcity of allowances.
• Carbon Border Adjustment Mechanism (CBAM) Integration: Although CBAM’s financial obligations commence in 2026, its transitional phase in 2025 is already shaping market dynamics. The gradual phase-out of free allowances under the EU ETS by 2034, in parallel with CBAM, will increase demand for purchased allowances.
• Potential EU ETS Linkage with the UK ETS: Analysts foresee a more bullish outlook for UK carbon prices in the second half of 2025, partly due to renewed optimism over a potential linkage with the EU ETS. Formal discussions are expected to begin following a May summit. Such integration would create a larger, more connected, and potentially more volatile trading environment across Europe.

While analyst projections for EUA prices in 2025–2026 vary, many expect upward pressure driven by these supply-restricting measures.
