INTEGRITY

WHAT IS INTEGRITY IN THE CONTEXT OF CARBON CREDITS?

Integrity is the confidence that a carbon credit represents a genuine, additional, and permanent climate outcome – one that reflects real emission reductions or removals, is accurately quantified, and would not have happened without the project. A high-integrity credit can be trusted to deliver the climate impact it claims.  

WHY DOES INTEGRITY MATTER IN THE VOLUNTARY CARBON MARKET?

Integrity is the foundation on which the credibility of the entire voluntary carbon market rests. Every credit represents a promise that a tonne of CO₂ has genuinely been avoided, reduced, or removed. When that promise doesn’t hold up – because a project wasn’t truly additional, over-credited its impact, or reversed after issuance – it undermines trust in the market as a whole and exposes buyers to reputational, financial, and regulatory risk. As corporate climate commitments come under growing scrutiny, integrity has become the deciding factor between credits that genuinely support net-zero pathways and credits that expose companies to accusations of greenwashing. For serious buyers, integrity isn’t a nice-to-have – it’s the license to operate in the market. 

KEY ELEMENTS OF CARBON CREDIT INTEGRITY 

  • Additionality
  • Permanence
  • Robust baseline setting
  • Accurate carbon accounting
  • Leakage prevention
  • Independent validation and verification
  • Transparent monitoring
  • No double counting
  • Social and environmental safeguards
  • Clear and credible claims

These reflect the core dimensions we look at when weighing a project’s carbon integrity – Additionality, Carbon Accounting, Permanence, Leakage and Co-Benefits – together with the partner reliability and safeguard checks that sit alongside them. 

HOW IS INTEGRITY ASSESSED? 

Integrity is assessed by working systematically through the core components of a project – Additionality, Carbon Accounting, Permanence, Leakage and Co-Benefits – and testing the evidence behind each one. For additionality, this means examining whether the project would have happened anyway: what alternative scenarios were considered, whether there are genuine financial or regulatory barriers to the project happening without carbon finance, and whether similar activities are already common practice in the region. Carbon accounting is reviewed for how conservatively the baseline, biomass, and carbon pools were quantified, and whether monitoring and reporting are robust and transparent. Permanence is assessed against the reversal risks relevant to that project type and geography – fire, drought, pests and disease, storms, flooding, sea-level rise, and anthropogenic risks such as encroachment or insecure land tenure – together with whether monitoring commitments extend meaningfully beyond the crediting period. Leakage is checked by looking at whether activities might simply displace emissions to a neighbouring area or the wider market. Co-benefits are reviewed for both ecological outcomes, such as biodiversity impact and monitoring, and social outcomes, such as community livelihoods and contribution to the UN Sustainable Development Goals. Alongside these, we at FORLIANCE also assess the project partner – financial health, governance and ownership transparency, and track record and whether safeguards such as Free, Prior and Informed Consent (FPIC), grievance mechanisms, and stakeholder engagement are genuinely in place, drawing on independent third-party ratings where relevant. 

INTEGRITY RISKS IN CARBON CREDIT PROJECTS 

Integrity risks show up differently depending on where you look. Additionality risk arises when a project’s baseline assumes more deforestation, harvesting, or degradation than is actually plausible – for example when comparable land nearby shows lower pressure than the baseline claims, or when similar conservation activities are already common practice in the area without carbon finance. Carbon accounting risk arises when baselines or biomass estimates are modelled optimistically rather than conservatively. Permanence risk covers both natural hazards – fire, drought, pests and disease, storms, flooding, sea-level rise and human-driven risks such as encroachment, conflict, or insecure land tenure and carbon rights, especially where monitoring doesn’t extend far enough beyond the crediting period. Leakage risk arises when project activities shift deforestation pressure to a neighbouring area rather than genuinely avoiding it. Safeguard risk includes inadequate Free, Prior and Informed Consent (FPIC), missing or ineffective grievance mechanisms, and insufficient stakeholder engagement. Because these risks are interconnected, a credible assessment needs to examine them together, not in isolation. 

HOW COMPANIES CAN IDENTIFY HIGH-INTEGRITY CREDITS 

Identifying high-integrity credits means looking past the certificate and into the evidence: how additionality is demonstrated (alternative scenarios, barrier analysis, financial additionality, common-practice checks), how conservative the carbon accounting is, how the specific permanence risks for that project type and geography are managed and buffered, whether leakage has been assessed, and whether safeguards – FPIC, grievance mechanisms, stakeholder engagement – are genuinely documented rather than just claimed. In practice, this means reviewing project design documents, monitoring reports, geospatial data, and financial models. Independent ratings from agencies such as Sylvera or BeZero, where available, offer an outside view worth weighing alongside a project’s own documentation. It takes real time, data access, and cross-disciplinary expertise – which is why many buyers choose to work with an experienced sourcing partner rather than build this capability from scratch. 
At FORLIANCE, this is the standard we hold every project and every partner to before it becomes part of our portfolio. 

FAQS ABOUT CARBON CREDIT INTEGRITY

What makes a carbon credit high integrity?

A high-integrity carbon credit is one where every link in the chain holds up: the emission reduction or removal is real and would not have happened without the project (additionality), it is quantified conservatively and accurately (carbon accounting), it will last (permanence), it doesn’t simply shift the problem elsewhere (no leakage), and it is backed by credible safeguards, transparent monitoring, and clear claims. High integrity means a buyer can rely on the credit to represent the climate outcome it claims, without hidden risks or overstated impact. 

Can a certified carbon credit still have integrity risks?

Yes. Certification confirms that a project follows an approved methodology and has passed a defined set of checks, but it doesn’t eliminate every integrity risk. Additionality assumptions can weaken as circumstances change, a baseline can later prove too generous once monitoring data comes in, and permanence events such as fire, pests, or encroachment can put stored carbon at risk after credits have already been issued. This is why credible due diligence looks at the underlying evidence itself, not just the certificate. 

How can companies assess carbon credit integrity?

Companies can assess integrity by examining the same components a rigorous due diligence process looks at: additionality (alternatives, barriers, common practice, financial additionality), carbon accounting (baseline quality, biomass modelling, reference region), permanence (reversal risk by hazard type and monitoring beyond the crediting period), leakage, and social and environmental safeguards, alongside the reliability of the project partner itself – financial health, governance, and track record. In practice this requires access to detailed project documentation and cross-disciplinary expertise in forestry, geospatial analysis, and finance – which is why many companies choose to work with an experienced sourcing partner rather than build this capability in-house. 

What is the difference between carbon credit quality and integrity?

Integrity and quality are related but distinct concepts. Integrity refers to whether a credit's core climate claim is real, in other words, whether one tCO2e claimed as reduced or removed is truly equivalent to one tCO2e of actual climate benefit; and that the reduction or removal is real and that the reduction or removal is real, additional, accurately accounted for, and durable. Quality is a broader concept that builds on that integrity foundation and also considers factors such as co-benefits (biodiversity, community livelihoods, SDG contributions), project design and governance strength, delivery reliability, and overall value to the buyer. In short: integrity is the non-negotiable baseline a credit must meet - does 1 tCO2e claimed equal 1 tCO2e in reality -, while quality describes how well a project performs across additional dimensions once that threshold is secured.
