The Moral Hazard of Megatonnes: Why Carbon Removal Ethics Must Outlast Our Carbon Budget

The promise of carbon removal is seductive. Imagine a technology that could vacuum the atmosphere clean, allowing us to keep flying, driving, and manufacturing while the planet heals. That vision has driven billions of dollars into direct air capture, enhanced weathering, and biochar projects. But there is a quiet danger in that seduction: the moral hazard of megatonnes. When we treat carbon removal as a get-out-of-jail-free card, we risk using future removals to justify present emissions — a trade that the planet cannot afford.

This guide is written for carbon removal buyers, sustainability officers, policy advisors, and anyone who writes a net-zero plan. We are not here to dismiss carbon removal. We are here to ask the harder question: how do we deploy removals without letting them become an excuse to delay the harder work of cutting emissions at the source? The answer is not simple, but it is urgent.

Why This Topic Matters Now

The carbon removal industry is at a tipping point. In 2023, global investment in carbon dioxide removal (CDR) surpassed $2 billion for the first time, and dozens of companies have signed offtake agreements for millions of tonnes of removal credits. At the same time, global emissions continue to rise. The tension is obvious: the more we talk about future removals, the less pressure there is to cut emissions today.

This is not a hypothetical problem. In corporate net-zero pledges, many companies rely on carbon removals to offset a significant portion of their residual emissions. A recent analysis of Fortune 500 climate plans found that over 60% of companies assume removals will cover at least 20% of their 2050 targets. But the technology to deliver those removals at scale does not yet exist — and the ethics of counting on it are shaky at best.

The core issue is what philosophers call moral hazard: when the availability of a safety net encourages riskier behavior. In the climate context, moral hazard means that the promise of future carbon removal can weaken the political will and economic incentives to reduce emissions now. If a company can buy a removal credit for $200 per tonne today, why invest in expensive operational changes to cut that same tonne? The answer, we argue, is that removal credits are not interchangeable with emission reductions. They serve a different purpose: cleaning up the legacy emissions we cannot avoid, not licensing new ones.

We need to separate two distinct goals. The first is emission reduction — stopping CO2 from entering the atmosphere. The second is carbon removal — pulling CO2 back out. They are complementary, but they are not substitutes. The moral hazard arises when we blur that line. This guide will help you see the difference clearly and build a strategy that avoids the trap.

The Scale Gap

To appreciate the risk, consider the numbers. Current global emissions are about 40 gigatonnes of CO2 per year. The entire carbon removal industry, including nature-based solutions, removes less than 2 gigatonnes annually — and most of that is from forestry and soil projects with uncertain permanence. Engineered removal (direct air capture, enhanced weathering) accounts for less than 0.01 gigatonnes. Even the most optimistic projections suggest that by 2050, engineered removal might handle 5–10 gigatonnes per year. That leaves a massive gap. If we rely on removals to offset even a fraction of ongoing emissions, we are betting on a technology that is decades away from maturity.

Core Idea in Plain Language

At its simplest, the moral hazard of megatonnes works like this: the more we believe that carbon removal will save us later, the less we act now. It is the same psychology that makes people skip saving for retirement because they expect a lottery win. But the climate lottery has terrible odds.

We can break the idea into three parts. First, there is the substitution fallacy: treating a tonne of removal as equivalent to a tonne of avoided emission. They are not equivalent because removal is uncertain, delayed, and reversible. A tonne avoided today is a tonne that never needs to be removed. Second, there is the discounting trap: assuming that future removals are cheaper or easier than current reductions. History suggests that early action is almost always cheaper than late-stage cleanup. Third, there is the accounting loophole: using removal credits to meet near-term targets that should be met with direct cuts.

Consider a concrete example. A company pledges to be net-zero by 2050. In its 2030 interim target, it plans to offset 30% of its emissions with carbon removal credits. That 30% represents a real tonnage of CO2 that will be emitted and must later be removed. If the removal credits do not materialize — because the technology fails, the market collapses, or the permanence is broken — the company has effectively emitted that CO2 with no plan to recapture it. The planet does not forgive that debt.

The ethical framework we propose is simple: carbon removal should be used only for residual emissions — the emissions that remain after all technically and economically feasible reductions have been made. It should not be used to offset emissions that could be avoided today. That distinction is the cornerstone of responsible carbon removal.

Why This Distinction Matters

Without this boundary, carbon removal becomes a tool for greenwashing. It allows companies to claim climate action without changing their operations. The worst-case scenario is a world where we build a massive carbon removal infrastructure just to offset ongoing fossil fuel use — a kind of atmospheric dialysis that keeps the patient alive but never cures the disease. That is not a sustainable future.

How It Works Under the Hood

To understand how moral hazard operates in practice, we need to look at the mechanics of carbon removal markets. The key actors are buyers (companies, governments), sellers (project developers), and verifiers (standards bodies, registries). Each has incentives that can either reinforce or undermine ethical removal.

Buyers typically purchase removal credits to meet voluntary or compliance targets. The credit represents one tonne of CO2 removed and stored. But the quality of that credit depends on three factors: permanence (how long the carbon stays locked away), additionality (whether the removal would have happened anyway), and leakage (whether the removal causes emissions elsewhere). A credit that fails on any of these dimensions is not a true tonne of removal — it is an accounting fiction.

Moral hazard creeps in when buyers prioritize low cost over quality. A cheap credit from a forestry project that might burn in a wildfire is not a reliable offset. But because it is cheap, it encourages more offsetting behavior. The buyer feels good, the planet does not.

On the seller side, project developers have an incentive to overstate their permanence or understate their risks. The market does not yet have robust insurance or guarantee mechanisms. When a project fails — say, a biochar facility shuts down or a direct air capture plant underperforms — the buyer is left with worthless credits. But by that time, the emissions have already occurred.

Verifiers are supposed to police this, but standards are still evolving. The Integrity Council for the Voluntary Carbon Market (ICVCM) has set high-level principles, but implementation is uneven. Many credits on the market today do not meet the Core Carbon Principles for permanence and additionality. The result is a market where moral hazard is not just possible — it is built into the incentives.

The Role of Permanence

Permanence is the single most important factor in removal ethics. Geological storage (injected into deep rock formations) can lock carbon away for millennia. Biochar and soil carbon last decades to centuries. Forestry projects last decades — if the forest is not cut or burned. The difference matters. A removal that lasts 100 years is not a permanent solution for a climate problem that will last millennia. If we use temporary removals to offset permanent emissions, we are simply deferring the problem to future generations.

Worked Example: The Corporate Net-Zero Plan

Let us walk through a realistic scenario. A mid-sized manufacturing company, call it EcoParts Inc., has committed to net-zero by 2050. Its current emissions are 500,000 tonnes CO2 per year. The company has a plan: reduce emissions by 50% by 2030 through energy efficiency and electrification, then offset the remaining 250,000 tonnes with carbon removal credits from 2030 onward.

On paper, this looks responsible. But look closer. The 2030 reduction target is ambitious but achievable. The problem is the removal plan. EcoParts has signed an offtake agreement with a direct air capture startup for 100,000 tonnes per year starting in 2030, and plans to buy the rest on the spot market. The startup has not yet built its first commercial plant. The technology is unproven at scale. The cost per tonne is $400, which is high but within the company's budget.

Here is where moral hazard surfaces. Because EcoParts has a removal plan, it feels less urgency to push harder on reduction. It could invest in more aggressive efficiency measures or switch to low-carbon materials, but those are expensive and disruptive. The removal credits offer a cheaper path — at least on the balance sheet. But the risk is that the removal credits will not materialize. If the startup fails, EcoParts has no backup. Its 2030 target becomes a promise it cannot keep.

Even if the credits do materialize, there is a deeper ethical question: should EcoParts be using removals to offset emissions that it could avoid with existing technology? For example, it could replace its gas-fired boilers with electric heat pumps, cutting another 50,000 tonnes. That would be more expensive in the short term, but it would be permanent. Instead, the company chooses to keep the boilers and buy removals. That is a choice — and it is a choice that increases the planet's risk.

The better approach is to use removals only for the emissions that cannot be eliminated, such as process emissions from cement or chemical reactions. For EcoParts, that might be 50,000 tonnes, not 250,000. By limiting removals to truly residual emissions, the company avoids the moral hazard trap and builds a more credible plan.

What Real Companies Are Doing

Some leading companies are already adopting this stricter approach. Microsoft, for example, has committed to removing more carbon than it emits by 2030, but it has also invested heavily in reducing its own emissions. Its removal portfolio is designed to address legacy emissions and hard-to-abate sectors, not to offset ongoing operational emissions. That is a model worth following.

Edge Cases and Exceptions

The rule of using removals only for residual emissions is clear, but edge cases test its boundaries. Consider the following scenarios.

Scenario 1: The aviation sector. Airlines have few near-term options for decarbonization. Sustainable aviation fuels are limited, and electric planes are years away. Should airlines be allowed to offset their emissions with removals? The answer is yes, but with conditions. The removals must be permanent and additional, and the airline must also invest in efficiency and fuel switching. Offsets should be a bridge, not a destination.

Scenario 2: The carbon removal startup itself. A direct air capture company needs energy to run its machines. If that energy comes from fossil fuels, the net removal is less than the gross. In some cases, the net could be zero or negative. This is an edge case where the removal technology itself creates moral hazard — it consumes energy that could be used to replace fossil fuels elsewhere. The solution is to power removal facilities with zero-carbon energy and to account for the full lifecycle emissions.

Scenario 3: Nature-based removals with co-benefits. Reforestation projects can sequester carbon while also improving biodiversity and water quality. Some argue that these co-benefits justify using nature-based removals even if permanence is lower. We disagree. Co-benefits are valuable, but they should not be used to justify weak carbon accounting. If a forest is likely to burn in 30 years, it should not be counted as a permanent removal. Better to separate the carbon accounting from the co-benefits and fund both separately.

Scenario 4: Government procurement. When governments buy removal credits, they have a responsibility to set an example. If a government uses removals to meet its Nationally Determined Contribution (NDC) under the Paris Agreement, it must ensure that the removals are not double-counted and that they do not replace domestic emission reductions. The EU's Carbon Removal Certification Framework is a step in the right direction, but it is not yet fully implemented.

When Moral Hazard Is Acceptable

There is one case where moral hazard might be tolerable: when removals are used to buy time for sectors that are truly impossible to decarbonize today. For example, cement production releases CO2 from the chemical reaction itself, not just from energy use. For those process emissions, removals are the only option. But even then, the removals must be permanent and the sector must continue to research alternative materials. The moral hazard is minimized when the removal is clearly temporary and coupled with a phase-out plan.

Limits of the Approach

The ethical framework we have outlined is not perfect. It relies on honest accounting, robust verification, and a shared understanding of what counts as residual. In practice, these conditions are often absent.

First, there is the problem of additionality. Many removal projects would happen anyway, even without carbon credit revenue. For example, a reforestation project that is already funded by a government grant is not additional. If a company buys credits from that project, it is not paying for new removals — it is paying for something that was already going to happen. That is not a real offset.

Second, there is the problem of double-counting. When a removal credit is sold to a company, the same removal cannot also be counted in a country's national inventory. But in practice, many credits are counted twice — once by the buyer and once by the host country. International accounting rules are still being developed, and the risk of double-counting is high.

Third, there is the problem of non-permanence reversal. Even geological storage can leak. Biochar can be burned. Forests can be cleared. The longer the storage period, the higher the risk of reversal. Current markets do not have adequate insurance or buffer pools to cover these risks. If a reversal occurs decades later, the buyer may no longer exist, and the climate impact is permanent.

Fourth, there is the governance gap. The voluntary carbon market is largely unregulated. Standards are set by private bodies with varying rigor. There is no global authority to enforce rules or penalize bad actors. This creates a race to the bottom, where cheap, low-quality credits crowd out expensive, high-quality ones.

Finally, there is the political economy of carbon removal. If removals become cheap and abundant, they could undermine the political will to regulate emissions. Why impose a carbon tax if we can just suck the CO2 out later? This is the ultimate moral hazard: the technology itself could delay the systemic changes needed to decarbonize the economy.

What These Limits Mean for Practitioners

For buyers, the takeaway is to be skeptical. Do not assume that a removal credit is a perfect substitute for a tonne of avoided emission. Demand transparency from sellers. Look for third-party verification. And most importantly, never use removals to justify inaction on reduction. The limits of the approach mean that removals are a supplement, not a solution.

Reader FAQ

What is the difference between carbon removal and carbon offset?

A carbon offset is a broad term that includes both emission reductions (e.g., building a wind farm) and carbon removals (e.g., direct air capture). Carbon removal specifically refers to pulling CO2 out of the atmosphere. The moral hazard is worse with removals because they are often less permanent and more uncertain than reductions.

Can I trust carbon removal credits from forestry projects?

Forestry projects can be part of the solution, but they face high risks of fire, pests, and land-use change. For ethical removal, we recommend prioritizing durable storage (geological or mineralized) over biological storage. If you do buy forestry credits, ensure they have a buffer pool and a long-term management plan.

How do I know if a removal credit is high quality?

Look for credits certified under the ICVCM Core Carbon Principles or the Carbon Removal Certification Framework. Check the permanence duration (at least 1,000 years for geological storage). Verify additionality by asking whether the project would exist without credit revenue. Avoid credits that are too cheap — if it costs less than $100 per tonne, it is likely not permanent.

Should my company buy removals now or wait?

Buy now, but buy wisely. Early investment helps scale the industry and drive down costs. But do not buy removals to offset emissions you could cut today. Use removals only for your hardest-to-abate emissions, and pair them with a strong reduction plan. The best strategy is to reduce first, then remove what remains.

What happens if the removal project fails?

That depends on the contract. Some offtake agreements include penalties or replacement obligations. Many do not. Before signing, ask what happens if the project underperforms or reverses. Insist on a guarantee or a buffer pool. If the seller cannot offer that, look elsewhere.

Is there a risk that carbon removal becomes a distraction from policy?

Yes. That is the core moral hazard. To avoid it, we recommend that governments and companies set separate targets for reduction and removal. Do not allow removals to count toward reduction targets. Treat them as a parallel effort to clean up legacy emissions. This keeps the focus where it belongs: on cutting emissions at the source.

Next Steps for Ethical Carbon Removal

We have covered the theory, the mechanics, and the pitfalls. Now it is time to act. Here are five specific moves you can make today.

1. Audit your net-zero plan. Identify which emissions you are planning to offset with removals. For each tonne, ask: could this be avoided instead? If yes, change the plan. Reserve removals for truly residual emissions.
2. Diversify your removal portfolio. Do not rely on a single technology or project. Invest in a mix of direct air capture, enhanced weathering, biochar, and durable storage. Spread the risk.
3. Demand transparency. Ask your removal suppliers for full lifecycle assessments, permanence guarantees, and third-party audits. Publish your removal purchases publicly so others can verify.
4. Support stronger standards. Advocate for regulatory frameworks that require additionality, permanence, and no double-counting. The voluntary market needs rules to prevent moral hazard.
5. Talk about the trap. Share this guide with your colleagues and peers. The moral hazard of megatonnes is not widely understood. The more people who recognize it, the harder it will be for bad actors to exploit it.

Carbon removal is a necessary tool for climate restoration. But it is not a license to pollute. The ethics of removal must outlast any carbon budget because the atmosphere does not forgive shortcuts. As we scale from pilot to megatonne, let us keep the moral hazard front and center. The planet is counting on us to get this right.
