Carbon Certification vs. Real Evidence

Carbon certification is a formal process that uses third-party auditors and methodologies to measure, verify, and validate carbon removal claims. While it is a critical tool for establishing transparency and creating a market for carbon removals, it does not guarantee genuine, real-world climate benefits. It is important to understand its function and limitations.

The role and limits of carbon certification

Certification bodies establish consistent methodologies for calculating carbon removal, ensuring that projects meet a minimum set of criteria, such as additionality (the removal would not have happened otherwise), permanence (durability of storage), and preventing leakage (emissions increasing elsewhere).

Certification involves independent third-party verification, which helps to create trust in the market by ensuring that claims are assessed by an accredited body.

For buyers, certification standardizes a carbon credit, providing a single, tradable unit (typically one tonne of CO₂) that can be used for offsetting.

The ability to sell certified carbon credits creates a financial incentive for projects, channeling investment into carbon removal activities.

What certification cannot guarantee

Greenwashing

Relying solely on certification can allow companies to purchase credits without fundamentally reducing their own emissions, a practice known as greenwashing. This can create a false sense of security and potentially hinder genuine decarbonization efforts.

Overestimation

Studies have shown that some certified projects, particularly in nature-based categories like forestry, have overestimated their actual carbon removal or emissions reduction benefits.

Permanence risks

The permanence of carbon removal from nature-based solutions is vulnerable to external threats, such as wildfires or land-use changes, which can re-release the stored carbon back into the atmosphere.

Varying quality

Not all certification standards are equally rigorous. For example, standards for engineered removals generally guarantee longer permanence than some nature-based approaches. This variability can make it difficult for buyers to distinguish high-quality credits from low-quality ones.

Why real-world evidence is more necessary than certification

While certification is a valuable part of the carbon market, robust, real-world evidence of carbon removal is what ultimately delivers climate impact.

AspectReal-World EvidenceCertification
FocusPrioritizes the actual climate outcome—the physical removal of CO₂ from the atmosphere.Focuses on compliance with a set of rules and protocols.
VerificationRelies on direct, physical measurement, often with advanced monitoring technologies (like sensors or satellites), to confirm that the carbon was actually removed.A point-in-time check that a project's design and processes conform to a methodology, which may or may not translate to the desired outcome.
IntegrityAddresses systemic issues like double-counting and fraud by using technologies like blockchain to create an immutable record of a unit of carbon removal.Vulnerable to weaknesses in methodologies and monitoring. Some standards can be more easily exploited or may contain loopholes.
TransparencyPuts a strong emphasis on transparent, verifiable data that is accessible to all stakeholders.While reports are often public, the complexity of methodologies can make it difficult for an average buyer to fully understand the climate impact.

The path forward

For the carbon removal market to achieve its full potential, it must move toward a future where certification is just one piece of a more comprehensive verification system based on real-world evidence. A strong verification framework would:

Use advanced monitoring technology: Incorporate digital and remote sensing tools to provide real-time, continuous data on removal projects.

Require robust baselines: Ensure projects are evaluated against a credible, standardized baseline that prevents the overestimation of benefits.

Develop robust liability mechanisms: Hold project operators financially responsible for any reversal of stored carbon, especially in nature-based projects.

Complement, not replace, mitigation: Position carbon removal as a crucial complement to direct emissions reduction, not a substitute for it.
