EU ETS Allowances (EUAs) & Where to Buy in 2025

The EU ETS Allowances (EUAs) are a popular tradable asset, and in this article, we provide in-depth information, highlighting the available options to buy the asset and the underlying factors to seriously consider when purchasing it.

Understanding EU ETS Allowances (EUAs): The EU Emission Trading System (EU ETS) is considered the biggest carbon credit market in the world. As an integral part of the EU Climate Policy, EU ETS operates primarily as a cap-and-trade process whereby the quantity of greenhouse gas (GHG) emissions allowable per port installation or shipping company within the EU is capped, and companies can buy and sell or trade emission allowances (EU Allowances or EUAs) among one another.

Buying EU ETS EUAs: The following are currently the available options for purchasing EU ETS EUAs They include participating in auctions at the primary market, purchasing EUAs from trading platforms (secondary market), and through retail access (also via carbon credit-trading platforms). Each of the above-mentioned options has its peculiar features that differentiate it from the others.

Factors to Consider Why Purchasing EU ETS EUAs: Purchasing or trading in EU ETS Credits is influenced by a number of important factors like tax and accounting issues, regulatory risks, price volatility, market availability, environmental impact, and liquidity and transparency. Paying serious attention to these factors can significantly streamline the trading of EU ETS Carbon Credits while implementing the EU Climate Policy.

Understanding EU ETS Allowances

The EU Emission Trading System (EU ETS) is considered the biggest carbon credit market in the world. As an integral part of the EU Climate Policy, EU ETS operates primarily as a cap-and-trade process whereby the quantity of greenhouse gas (GHG) emissions allowable per port installation or shipping company within the EU is capped, and companies can buy and sell or trade emission allowances (EU Allowances or EUAs) among one another.

On the other hand, Carbon credits are a broader term that covers any tradable certificate that permits an entity to emit certain amounts of carbon dioxide.  Therefore, carbon credits may include voluntary offset credits obtainable from reforestation and renewable energy projects. While all EUAs are categorised as carbon credits, not all carbon credits are EUAs, and EUAs specifically work within the EU ETS. [1]

Buying EU ETS EUAs – Some Available Options

The following are currently the available options for purchasing EU ETS Carbon Credits: They include participating in auctions at the primary market, purchasing carbon credits from trading platforms (secondary market), and through retail access (also via carbon credit-trading platforms). Each of the above-mentioned options has its peculiar features that differentiate it from the others. [2], [3], [4]

Primary Market (Auctions)

In the primary market, EUAs are auctioned via the European Energy Exchange (EEX)—the Common Auction Platform (CAP3) for 25 EU Member States, 3 EEA-EFTA States, and other EU funds such as the Modernisation Fund and Innovation Fund.

Secondary Market (Trading Platforms)

The previously issued EUAs are traded in the secondary market as spot, futures, or options contracts on platforms like the European Energy Exchange (EEX) and ICE Endex. Due to its flexibility, the secondary market ensures liquidity, price stabilisation, and streamlines compliance and investment strategies.

Retail Access (via platforms)

The retail access to EU ETS carbon credits (EUAs, in particular) has been restricted only to financial institutions and compliance entities. However, new opportunities for trading EU ETS carbon credits are now emerging as private investors can trade on platforms such as Homaio, some exchange-traded funds (ETFs), and mutual funds.

Factors to Consider When Purchasing EU ETS EUAs

Purchasing or trading in EU ETS Credits is influenced by a number of important factors like tax and accounting issues, regulatory risks, price volatility, market availability, environmental impact, and liquidity and transparency. Paying serious attention to these factors can significantly streamline the implementation of the EU Climate Policy. [5], [6], [7]

Tax & Accounting Issues

The European Securities and Markets Authority (ESMA) encourages all entities to be transparent in disclosing their EUA valuation methods, risk exposures in relation to carbon pricing, and their emission liabilities. This is a complex requirement in the sense that regulated entities must clearly state whether their EUAs are estimated at full market value, initial market value, or nominal value. Concerning taxes, EUA transactions are subject to EU VAT and corporate taxes. In other words, gains or losses from EUA transactions may be taxable or tax-deductible.

Regulatory Risks

In order to prevent market abuse, the EU has put in place some regulatory checks. These include laws that moderate speculative trading, prevent fraudulent practices, and supervise the recent attempt to tokenise carbon credits or establish trading of blockchain-based EUA derivatives. Unfortunately, some of these regulations, like Linear Reduction Factor (LRF) and the Market Stability Reserve (MSR), are subject to periodic modifications, creating uncertainty in the markets.

Price Volatility

Factors such as lower industrial emissions, geopolitical and energy crises, sudden changes in policies, macroeconomic uncertainties, and intense speculative trading can make carbon credit pricing fluctuate immensely. More importantly, imbalanced auction dynamics, such as when 90% of the auctioned volume is purchased by less than 10% of the participants. This unequal practice can lead to sudden price swings, seriously affecting low-volume investors and retail traders.

Market Availability

Owing to strict regulatory and compliance requirements, the EUA market is considered to be robust and one of the most liquid carbon markets worldwide, estimated to be worth billions of euros in daily trading volume. However, it must be noted that this liquidity can vary based on the contract type and maturity. Generally, front-year futures are regarded as the most active or volatile.

Environmental Impact

The concept behind EU ETS carbon credits (EUAs) is that entities are given the right to emit one tonne of CO₂ equivalent per annum, and any emissions over the capped level can be traded. A situation where there is a sharp reduction in the rate of GHG emissions (when more shippers and port installations are turning to green and renewable energy) can cause the volume of tradable EU ETS carbon credits (EUAs) to be drastically lowered. While this is exceedingly good for the environment, it threatens the continuity and sustainability of this unique EU environmental policy.

Key Takeaways

As a cap-and-trade procedure, trading in EU ETS carbon credits (EUAs) offers entities (shippers and port authorities) some opportunities. If a shipper emits less carbon dioxide or has lower verifiable EUAs, it can save on compliance costs. On the other hand, if it overperforms, emitting less than its allowable EUAs, it can trade the surplus on the carbon market. This article has provided all the necessary information that a shipper requires in order to successfully execute the EU ETS carbon credits trading process.
