An introduction to the correlation of EUAs with other assets

Investing in carbon allowances (EUAs) offers portfolio diversification and protection against market swings due to their low correlation with other assets. EUAs can act as an inflation hedge and are engineered for long-term price appreciation, making them a valuable addition to a well-diversified green portfolio.

European Union Allowances (EUAs) are an excellent option for portfolio diversification. Historically, they have had a low correlation with other asset classes, offering effective protection against unfavorable portofolio swings coming from the broad financial markets.

Carbon allowances have a unique structure as they combine elements of a policy tool and a marketplace. Thus, they are less sensitive to major traditional asset fluctuations.

Unlike most investing options, EUAs can act as an inflation hedge. Indeed, a significant contributor to inflation is often the energy sector. As energy prices increase, inflation rises. Likewise, EUA prices often follow suit when energy sources such as gas become more expensive. In short, EUA prices can be positively correlated with inflation, and carbon allowances can help compensate for the loss of purchasing power due to rising inflation.

Although carbon prices can fluctuate temporarily and have variable correlations with other assets, EUAs are distinguished by their expected long-term price appreciation, thanks to a decreasing supply.

As both a policy tool and a financial instrument, carbon allowances are engineered for a steady price growth. Also, their historically low correlation with most asset classes makes them a valuable addition for any well-diversified portfolio.

UKAs and EUAs: Why Hold Both When You're Already Invested in European Carbon

If you're already invested in European EUAs, do you need to bother with UK UKAs? Short answer: yes. Long answer: the two markets are correlated at around 80% over time, but that correlation hides distinct dynamics (political, industrial, calendar-based) that make UKAs both linked and differentiated from EUAs. That's precisely what makes the combination interesting: an EUA core for liquidity and depth, a UKA satellite for political catch-up and the associated risk premium. Here's why.

What is the Climate Impact of a UKA? One Tonne of CO₂ Pulled Off the Market, Measured and Verifiable

Holding a UKA does something simple and radical: it takes one right-to-emit tonne of CO₂ off the UK market. Not an offset, not a voluntary credit, not a tree-planting promise. A regulated allowance, accounted for by the State, that exits the system the moment a non-compliance investor holds it. It's what we call an additional climate action: measurable, verifiable, legally framed. Here's how it works, and why this impact is one of the most robust in today's climate-finance landscape.

The UKA-EUA Convergence Play: Anatomy of a Catch-Up in Motion

May 2025, London summit: Keir Starmer and Ursula von der Leyen formally state their intention to link the UK ETS to the European system. A new term has been circulating among carbon analysts ever since: the Convergence Play. The mechanic is simple: UKAs trade today around 20% below EUAs, a discount that has already partially closed since May 2025. The residual mechanical upside is around +20 to +25%. Here's how it works, why it's happening now, and what the Swiss-EU precedent teaches us.
