Evaluating Carbon Credit Investment Funds

Companies worldwide are pledging to cut their greenhouse gas emissions to zero. As these corporate commitments grow, retail investors are looking for ways to profit from the transition. Carbon credit investment funds offer a direct way to bet on the rising cost of pollution, but they come with unique risks and complex financial structures.

How Carbon Markets Actually Work

Before buying into a carbon fund, you need to understand what you are actually purchasing. The carbon market is not a single entity. It is divided into two distinct categories: compliance markets and voluntary markets.

Compliance Markets

Compliance markets are created and strictly regulated by governments. Under a “cap-and-trade” system, a government sets a legal limit on the total greenhouse gases that certain industries can emit. The government then issues or sells carbon allowances. Every allowance gives a company the legal right to emit one metric ton of carbon dioxide.

If a factory emissions exceed its allowances, the company must buy more allowances on the open market or face massive fines. To force companies to clean up their operations, governments slowly reduce the total number of allowances available each year. The largest compliance markets are the European Union Emissions Trading System (EU ETS) and the California Cap-and-Trade Program.

Voluntary Markets

Voluntary markets are completely different. These are driven by corporate sustainability pledges rather than government laws. A tech company might promise to be “carbon neutral” by buying carbon offset credits. These credits are generated by projects that reduce or remove carbon from the atmosphere, such as planting trees or building wind farms. Registries like Verra and Gold Standard verify these projects. However, this market is largely unregulated and has faced heavy criticism for questionable environmental benefits.

How Retail Investors Can Buy In

You cannot easily buy a physical carbon allowance or open an account directly with the European Union. Instead, retail investors use Exchange Traded Funds (ETFs) to gain exposure. These funds do not buy physical carbon credits. They buy carbon futures contracts. A futures contract is a legal agreement to buy or sell a specific asset at a predetermined price at a specified time in the future.

By holding these futures contracts, the ETFs track the daily price movements of the carbon markets. Here are the most prominent funds available to everyday investors:

• KraneShares Global Carbon Strategy ETF (KRBN): This is the largest and most popular carbon ETF. It tracks the IHS Markit Global Carbon Index. KRBN gives you broad exposure to the three largest compliance markets: the European Union, California, and the Regional Greenhouse Gas Initiative (a coalition of eastern US states). The fund charges an expense ratio of 0.78%.
• KraneShares European Carbon Allowance Strategy ETF (KEUA): If you want to focus entirely on Europe, this fund is a pure play on the EU ETS. The European market is the oldest and most heavily traded carbon market in the world. In early 2023, European carbon allowances famously crossed 100 euros per metric ton for the first time, proving the massive demand in this sector.
• KraneShares California Carbon Allowance Strategy ETF (KCCA): This fund targets the joint cap-and-trade program run by California and the Canadian province of Quebec. California has some of the strictest environmental laws in the United States, which creates a strong foundational demand for these allowances.

The Financial Case for Carbon Credits

Investors are drawn to carbon ETFs for a few specific reasons.

First, the basic economic mechanics of cap-and-trade systems are designed to push prices higher. Because governments legally mandate a shrinking supply of carbon allowances every year, the price should naturally rise if industrial demand remains steady. You are essentially investing in a government-engineered supply shortage.

Second, carbon credits offer excellent portfolio diversification. Historically, the price of carbon allowances has shown a low correlation to the S&P 500 and the bond market. If tech stocks drop or interest rates rise, the price of a European carbon credit is largely unaffected. The price is dictated almost entirely by government policy and industrial output, making it a great hedge against traditional market volatility.

Major Risks to Consider

While the upside is clear, carbon funds are highly specialized investments that carry significant risks.

Regulatory Risk Because compliance markets are created by politicians, they can be destroyed or altered by politicians. If an energy crisis hits, a government might choose to issue millions of emergency allowances to keep power plants running cheaply. This sudden flood of supply would instantly crash the price of your ETF.

Economic Downturns Carbon prices are tied to industrial production. If a major recession hits Europe, factories will slow down, power plants will burn less coal, and companies will not need to buy as many carbon allowances. When demand drops in a recession, carbon prices typically fall right alongside it.

The Greenwashing Backlash If you look into voluntary carbon funds, you must be extremely careful. Investigative reports over the last few years have revealed that millions of voluntary offset credits (especially those related to forest protection) had zero actual impact on the climate. This has caused severe reputational damage to the voluntary market, leading many corporations to quietly stop buying offsets.

Frequently Asked Questions

Are carbon ETFs considered safe investments?

No. Carbon ETFs are considered alternative investments and carry high volatility. They are highly sensitive to political decisions, energy prices, and sudden changes in environmental regulations. They should only make up a small, speculative portion of a broader investment portfolio.

What is the difference between a carbon offset and a carbon allowance?

A carbon allowance is a government-issued permit that allows a company to emit one ton of carbon (used in compliance markets). A carbon offset is a certificate proving that one ton of carbon was removed or avoided by a specific environmental project (used in voluntary markets). Most major ETFs only invest in government allowances.

Do carbon credit ETFs pay dividends?

Yes, many of them do. Because these funds buy futures contracts, they must hold a large amount of cash collateral. The funds usually invest this cash in short-term government bonds or money market funds. The interest earned on that cash is periodically paid out to ETF shareholders as a dividend.
