Carbon credits are becoming an increasingly common part of business sustainability strategies. As pressure grows from investors, customers and regulators, companies are looking for ways to reduce their environmental impact – or, at the very least, balance the emissions they can’t yet eliminate.

Carbon credits offer one of a few ways to do that. But while they’re quite commonly used, they’re also often misunderstood – especially for those who don’t have experience using them.

So, for that reason, for businesses, understanding how they work and when to use them is essential in this day of age.

What Are Carbon Credits?

A carbon credit represents the reduction or removal of one metric tonne of carbon dioxide, or an equivalent greenhouse gas, from the atmosphere. Businesses can buy these credits to offset emissions that they produce as part of their general operations.

The credits are typically created by environmental projects. These might include reforestation, renewable energy generation, methane capture or conservation initiatives. Each project calculates how much carbon it removes or prevents, and that amount is converted into credits that can be sold.

In practice, this means a company that produces emissions can purchase credits to compensate for its environmental impact. The emissions still exist – nobody can make them magically disappear – but they’re balanced by reductions elsewhere. And, this is why carbon credits are often referred to as offsets.

Why Businesses Use Carbon Credits

Many businesses can’t eliminate emissions overnight which makes sense; it’s a small job. Manufacturing processes, logistics, travel and data infrastructure all create unavoidable carbon output. Carbon credits allow companies to take action while they work toward longer-term reductions.

Often, they’re used to support sustainability commitments, achieve carbon neutrality targets or demonstrate environmental responsibility to stakeholders. For growing companies, they can also be a relatively quick way to begin addressing emissions without needing to redesign operations immediately.

But, carbon credits are most effective when used alongside reduction efforts, definitely not instead of them. Businesses that rely entirely on offsets may face criticism, particularly as scrutiny around sustainability claims increases. Using offsets should always be in conjunction to other strategies.

How Carbon Credits Work In Practice

When a business buys carbon credits, it’s essentially funding a project that reduces or removes emissions. These credits are issued by organisations that measure and verify environmental impact. Once they’ve been purchased, credits are retired, which means that they can’t be reused or resold – from that point, they’re null and void.

Now, there are two main types of carbon markets. Compliance markets are regulated by governments and apply to companies that must meet emissions caps, whereas voluntary markets allow businesses to buy credits even if they’re not legally required to. Most companies that use carbon credits operate in voluntary markets, but this may very well change given evolving environmental policies around the world.

The voluntary carbon market has grown rapidly as businesses set net-zero targets. Companies can choose projects aligned with their values, like forest restoration, clean energy or community-based sustainability initiatives.

Carbon Credits Vs. Reducing Emissions

It’s really important to distinguish between reducing emissions and offsetting them, because they’re not synonymous. Reducing emissions involves changing operations, like switching to renewable energy, improving efficiency or redesigning supply chains. Offsetting, however, involves compensating for emissions that still occur.

Carbon credits fall into the second category. They don’t directly reduce a company’s own emissions. Instead, they fund reductions elsewhere. This makes them useful for unavoidable emissions, but less suitable as a standalone sustainability strategy.

Many climate frameworks recommend a hierarchy. Businesses should first measure emissions, then reduce them where possible, and finally offset what remains. Going about it this way help ensure that carbon credits support genuine progress rather than replace it.

Risks Businesses Should Consider

Carbon credits come with several risks, particularly around quality and credibility. Not all projects deliver the same environmental impact – some might overestimate emissions reductions, while others may not provide long-term benefits. It’s all part of the process, but these risks should still be mitigated.

Permanence is another concern that needs to be properly considered. For example, a reforestation project may absorb carbon today, but future events like wildfires or deforestation could reverse those gains. This creates uncertainty about whether emissions are truly offset over time.

There’s also reputational risk that plays a massive role in how and why businesses use offsets. Businesses that rely heavily on carbon credits without reducing emissions may face accusations of greenwashing (and many do, even unfairly so). For that reason, stakeholders are increasingly looking for transparency and tangible operational change.

Pricing volatility, as a final risk to consider, means that carbon credit prices can vary depending on project type, certification and demand. This can make long-term planning more difficult for businesses relying on offsets.

Who Should Be Using Carbon Credits?

Carbon credits are most useful for businesses with unavoidable emissions. This would typically be companies in logistics, manufacturing, travel and technology infrastructure. They can use credits to offset emissions while transitioning to lower-carbon operations.

They can also be very helpful for companies that are aiming to set net-zero targets. Credits provide a way to address residual emissions that are difficult to eliminate completely, so this makes them a practical component of broader sustainability strategies.

Startups may also use carbon credits to demonstrate environmental responsibility early on, particularly if sustainability is central to their brand. But, this approach works best when combined with efforts to minimise emissions from the start.

But, Think Carefully Before Using Them

Businesses should be cautious if carbon credits are their only sustainability action. If emissions remain high and reductions are not planned, offsets can appear superficial. This is especially risky for companies making public environmental claims.

Companies with easily reducible emissions should also prioritise operational changes first. For example, switching energy providers or reducing travel may deliver more meaningful impact than purchasing credits.

Using carbon credits without a clear emissions strategy can create confusion and weaken credibility. Basically, it’s worse than doing nothing at all.

Why Carbon Credits Over Other Sustainability Approaches?

Carbon credits differ from other sustainability actions because they compensate for emissions rather than eliminate them. Measures like improving efficiency, electrifying operations or redesigning supply chains directly reduce emissions at source.

These approaches often require more time and investment, but they provide longer-term impact. Carbon credits offer flexibility, particularly during transition periods. And this is why many businesses combine both strategies.

Some companies also invest directly in sustainability projects instead of purchasing credits. This can provide greater transparency and alignment with business goals, but it typically requires more resources and involvement.

So, Why Are Businesses Paying Attention Now?

Interest in carbon credits is growing as sustainability expectations increase, and it’s likely that this trend will continue in the same trajectory. Investors are demanding emissions reporting, customers are prioritising environmentally responsible brands and regulators are tightening disclosure requirements.

At the same time, businesses are under pressure to act quickly. Carbon credits offer a faster way to demonstrate progress, particularly while operational changes are still underway.

However, scrutiny is also increasing. Stakeholders now expect companies to explain how credits are used, what projects are supported and how emissions are being reduced overall.

Carbon credits allow businesses to offset emissions by funding projects that reduce or remove carbon elsewhere. They can play a useful role in sustainability strategies, particularly for unavoidable emissions and transitional periods.

But, most importantly, they’re not a complete solution by any means. Credits don’t eliminate emissions, and their impact depends on project quality and transparency. Businesses that rely on them without reducing emissions risk reputational and strategic challenges.

The most effective approach in this sphere is a balanced one. Measure emissions, reduce them where possible and use carbon credits to address what remains. When used thoughtfully, carbon credits can support meaningful progress rather than simply offsetting it.
