Carbon Trading and Sequestration: What Counts as Climate Progress?

Carbon trading concerns market instruments. Carbon sequestration concerns storage. They can work together, but buying something called “carbon” does not tell you whether an emission was prevented, CO₂ was removed from the air or an allowance changed hands.

The distinction is easiest to see in a cap-and-trade system. The European Commission explains the EU Emissions Trading System as a capped market in emission allowances. An allowance permits an emission within that system. It is not a certificate showing that the same quantity was extracted from the atmosphere.

For example, Verra defines its Verified Carbon Units in tonnes of CO₂ equivalent reduced or removed. The shared unit helps accounting, while the project information explains the kind of outcome being credited. A reduction credit should not be described as a removal credit simply because both use tonnes.

Carbon capture at a fossil-fueled industrial facility intercepts CO₂ before it reaches the atmosphere. Direct air capture starts with CO₂ already in ambient air. The Department of Energy’s definition of carbon dioxide removal explicitly distinguishes removal from fossil and industrial point-source capture.

A project can be environmentally worthwhile without every part of its activity qualifying for credits. Crediting asks a more specific question: what additional reduction or removal does the intervention produce under the applicable methodology?

Gold Standard’s guide to voluntary carbon market integrity explains additionality and baseline setting. Additionality concerns whether the credited activity or outcome would happen without the carbon finance. A baseline describes the comparison against which the improvement is calculated.

Consider two hypothetical restoration projects. One is already fully funded and committed. Another needs carbon revenue to close a funding gap. Those circumstances call for different additionality assessments. A beautiful landscape photograph cannot resolve the question.

The comparison also needs to be credible. If the forecast of what would happen without a project is exaggerated, the apparent improvement can be exaggerated too. Gold Standard identifies conservative baseline setting as central to the integrity of the result.

My practical concern is whether the explanation connects money, activity and outcome. Who does the work? What changes because the project proceeds? Which part of that change is being claimed? A proposal becomes easier to understand when those connections are visible.

“Sequestration” covers several physical processes. The DOE explanation of biological and geological sequestration describes how photosynthesis moves atmospheric carbon into vegetation, how some enters soils and how captured CO₂ can be stored underground.

For land-based businesses, these questions connect with the operational considerations in my regenerative agriculture and carbon markets consulting work. A farmer needs to understand the practice and its obligations alongside the environmental claim.

Coastal projects also belong in the wider conversation about the future of marine conservation. Carbon is one reason to care about an ecosystem. Its wildlife, water, livelihoods and resilience have value that should remain visible in the project’s story.

A direct air capture facility needs energy, materials and a destination for the CO₂. DOE’s direct air capture overview describes systems using solvents or solid sorbents to separate the gas from air. Regenerating the capture material and handling the concentrated CO₂ require further work.

The emissions associated with that work belong in the climate assessment. DOE’s life cycle assessment guidance for direct air capture with storage explains why net removal requires a view across the process, including its other environmental effects.

A product-use claim needs the same attention to the carbon’s destination. Ask whether the carbon stays stored or returns to the atmosphere during use or disposal. “Captured,” “used” and “durably stored” are useful descriptions only when the subsequent steps are explained.

The Integrity Council’s Core Carbon Principles address issues including transparent records, independent assessment, additionality, permanence, quantification and avoiding double counting. They provide a useful framework for understanding the evidence a crediting system needs.

Leakage adds another question: did the intervention cause emissions to increase, or removals to decrease, somewhere outside the project boundary? The GHG Protocol’s guidance on credited reductions and removals includes this displacement effect among the issues that crediting must address.

For example, a hypothetical land project might reduce an activity within its own boundary while that activity expands elsewhere because of the intervention. A project assessment needs to consider that connection. A map drawn around the project does not draw a boundary around the atmosphere.

Environmental specialists, data providers and project operators each contribute different evidence. My environmental services consulting work focuses on helping organizations explain those capabilities and the decisions they support.

The IPCC’s comparison of removal approaches identifies different storage timescales and risk profiles. Carbon in vegetation and soils has different vulnerabilities from carbon stored in suitable geological formations. The distinction matters when assessing how a removal contributes over time.

A storage claim should explain the monitoring period and what happens if carbon is released again. The Integrity Council’s permanence principle calls for measures to address reversal risk and compensate for reversals where that risk exists.

I would want the project team to name the responsible party, the monitoring arrangement and the response to a loss. Those answers should survive a change in project staff or ownership. The carbon may be underground, but responsibility for it should be easy to find.

Verra’s Verified Carbon Standard overview separates project development and validation from monitoring, verification and issuance. The sequence helps explain why a planned project is not evidence that all of its expected future outcomes have already occurred.

Verra makes its issuance and retirement records publicly available. A purchase confirmation and a retirement record serve different purposes. For an intended use, the documentation should show what was delivered and the status of the specific units.

A commitment to future delivery can help a project develop, but the wording should identify it as future delivery. Compare the delivery period, conditions and evidence with the claim being made today. This keeps project ambitions and completed outcomes understandable.

The GHG Protocol’s credited-emissions guidance distinguishes purchased or retired credits from the company’s physical greenhouse gas inventory. It calls for separate reporting of credits rather than directly deducting them from reported scope 1, 2 or 3 emissions.

For a business explanation, start with the action actually taken. Did operations release less greenhouse gas? Did the company finance a project? Did it purchase and retire identified units? Describe the period, boundaries and evidence for that action. Then explain any broader claim using the relevant reporting or claims framework.

For example, a company could clearly describe a purchase and retirement of credits from a named project, while separately reporting its operational emissions and reduction efforts. That statement gives readers something concrete to inspect. A general “climate positive” label leaves the underlying activity and accounting unresolved.

Community and ecological benefits deserve the same specificity. A project may support habitat, local work or access to resources. Name the benefit and the evidence for it. A carbon figure alone does not describe every effect on the people and places involved.

DOE’s direct air capture research overview describes the work of separating a dilute gas from air and the energy and cost challenges involved. Improvements to capture materials and processes matter, alongside the practical arrangements for storage.

Research into plants, microbes and soil carbon stability also continues, as DOE’s sequestration overview explains. Better understanding can improve the assessment of changes in land management.

My view is that stronger projects will make the entire chain easier to examine: the activity, the measurements, the accounting, the delivery record and the long-term responsibilities. A new instrument or a faster dashboard is useful when it improves that understanding.

The IPCC’s removal factsheet emphasizes that removal complements deep emissions reductions. Both belong in the discussion of energy, industry and infrastructure. The work of reducing new emissions continues while removal methods develop.

If I were reviewing how a project is presented, I would begin with a short evidence brief: what happens, where it happens, when the outcome is expected, how it is assessed and who remains responsible. The supporting detail can be extensive. The explanation should still be coherent.

Then follow one claimed tonne through the story. Identify its source, the intervention, the comparison, the deductions and the destination. If a credit is involved, identify the program, the unit and its status. Missing connections become much easier to spot when the discussion follows an actual claim.

Carbon trading and sequestration can contribute to climate progress when their physical outcomes and accounting support the promise. The strongest explanation shows that connection clearly enough for another person to examine it. That is useful for customers, communities and the people doing the work.
