Understanding the projected trajectory of carbon allowance prices under the EU Emissions Trading System (EU ETS) is vital for European businesses seeking to manage compliance costs and maintain competitiveness. The market’s dynamics are fundamentally governed by the “cap and trade” principle, whereby a steadily declining emissions cap ensures allowance scarcity and maintains market value, thereby incentivising cost-effective emissions reductions across regulated sectors. Since its inception in 2005, the EU ETS has grown into the world’s largest carbon market and plays a central role in Europe’s climate strategy, compelling polluters to pay for their greenhouse gas (GHG) emissions and generating significant revenue to fund the green transition.

Key Drivers of EU ETS Carbon Prices

Carbon prices under the EU ETS are influenced by several interrelated supply and demand factors.

On the supply side, the annual reduction in the emissions cap is a primary driver. The accelerated linear reduction factor, set at 4.3% annually from 2024 to 2027 and increasing to 4.4% from 2028, directly limits the volume of available allowances, exerting upward pressure on prices. This tightening ensures long-term scarcity, preserving the market’s incentive structure. Complementing this mechanism is the Market Stability Reserve (MSR), which manages imbalances by withdrawing allowances from circulation when surpluses are excessive (e.g., 24% of total allowances if levels exceed 833 million) or releasing them when scarcity becomes too severe (below 400 million). In 2024, the circulation threshold of 400 million triggered the invalidation of over 2.8 billion allowances across two years, highlighting the MSR’s role in shaping supply. While fostering market balance, this regulatory intervention also contributes to price volatility.

In parallel, the gradual phase-out of free allowance allocations increases the proportion of allowances businesses must purchase on the open market. This heightens demand in the face of a declining supply, raising compliance costs. By deliberately engineering scarcity, regulators ensure a robust carbon price, making emissions sufficiently costly to drive systemic changes in production and energy use.

On the demand side, macroeconomic conditions are key: strong economic growth typically increases industrial output and, hence, emissions, raising demand for allowances. Similarly, slower-than-expected decarbonisation within covered sectors will prolong high demand. Energy mix dynamics also influence demand; for example, coal-fired generation requires more allowances than natural gas, thus shifting demand based on relative fuel prices.

A significant forthcoming demand driver is ETS2, the expanded emissions trading system due to launch in 2027. It will encompass road transport, buildings, and smaller industries, bringing carbon pricing to a far broader range of emitters. Once implemented, the EU ETS is expected to cover 78% of total GHG emissions across the European Economic Area (EEA).

Expert Forecasts (2025–2030)

Expert analyses project a consistent upward trend in EU ETS carbon prices through to 2030, particularly in light of ETS2’s introduction. According to BloombergNEF, prices under ETS2 could rise to €149 per tonne by 2030, making it the world’s most expensive cap-and-trade scheme. Other analysts foresee ETS2 prices stabilising around €100 per tonne by the same year. These projections suggest a major shift in carbon cost burdens, from heavy industry and power (currently under ETS1) to consumer-oriented sectors.

This will translate into tangible cost increases: road transport bills may rise by 22–27%, while home heating expenses could increase by 31–41% if the costs are fully passed on to consumers. Such impacts could trigger political and social resistance, as already observed in Member States like Poland, the Czech Republic, and Slovakia.

For EU ETS1, prices are similarly expected to trend upwards, driven by reduced supply and expanded sectoral coverage. While the short-term effects may be economically painful, prices are expected to stabilise post-2030, as low-carbon alternatives like electric vehicles and heat pumps become more widely adopted and affordable.

Strategic Implications for European Businesses

In response to these market developments, European businesses must adopt more sophisticated carbon management strategies. The first step is to define and quantify expected carbon budgets by aligning future production scenarios with estimated EUA expenditure. This involves scenario planning, cost modelling, and evaluating when investment in decarbonisation becomes more financially advantageous than purchasing allowances. Without action, companies could see CO₂ costs rise between 2.5 to twentyfold by 2030, depending on sectoral exposure.

Timing of procurement is another critical strategic decision. Companies must evaluate whether to spread purchases throughout the year using a pound-cost averaging method or concentrate procurement closer to the surrender deadline based on cash flow and market trends. To mitigate exposure to price volatility, firms should consider financial instruments like forwards and futures contracts, standard hedging tools in commodity and energy markets.

Given the growing complexity of the EU ETS, carbon management must be approached with a financial markets mindset. It is no longer sufficient to treat emissions as a compliance obligation managed by operations or finance teams alone. Instead, businesses should employ techniques such as forecasting, hedging, and active portfolio management, similar to the strategies used for commodities and currencies.

Internal collaboration and training are also essential. Effective carbon strategy requires cross-functional cooperation, integrating finance, operations, compliance, and sustainability teams. Educating staff on emissions markets, regulatory updates, and procurement options ensures that all departments can contribute to cost control and compliance.

Ultimately, the best long-term hedge against rising EUA prices is early investment in decarbonisation. Such investments reduce ongoing EUA needs, unlock value from unspent free allowances, and position businesses for regulatory and market advantage. Continual monitoring of EUA prices, market trends, and policy developments is essential for agile, data-driven decision-making. Additionally, benchmarking carbon intensity against competitors will help businesses understand their positioning in a market increasingly defined by carbon efficiency.
