Why Integrity Matters in Carbon Sourcing


As the voluntary carbon market (VCM) matures, one question matters more than ever: how do you identify carbon credits that truly deliver on their promises?

Despite media skepticism, most businesses are not stepping back from climate commitments—they’re doubling down. Alongside this momentum, multiple initiatives are raising the bar for integrity in carbon markets, helping buyers ensure that every tonne of CO₂ they purchase represents a real, measurable, and lasting climate impact.

But navigating the growing number of standards, principles, and schemes can be overwhelming. This guide breaks down what integrity really means, the benchmarks you should know, and practical steps for finding high-quality credits.

What Integrity in Carbon Markets Means

A high-integrity carbon credit should represent a genuine climate benefit:

  • Verified – Independently assessed and certified.

  • Additional – The reduction or removal wouldn’t have happened without carbon finance.

  • Permanent – Carbon stays out of the atmosphere for the long term.

  • Unique – Free from double counting under national or corporate claims.

  • Transparent – With accessible project information and methodologies.

  • Science-aligned – Contributing to credible net-zero pathways.

Put simply, integrity gives buyers confidence. It ensures carbon credits aren’t just a line item in a sustainability report but a tangible contribution to climate goals.

Why Buyers Should Care

Integrity isn’t just about technical rigor—it’s about trust, credibility, and impact.

  • Trust and confidence – Companies can credibly integrate credits into science-based climate strategies.

  • Real climate impact – Directing finance to projects that deliver genuine emissions reductions or removals.

  • Climate leadership – Demonstrating responsibility and transparency to stakeholders.

  • Risk management – Staying ahead of regulatory, reputational, and financial risks.

  • Market growth – Building confidence that enables the VCM to scale effectively.

The Emerging Integrity Benchmarks

Several frameworks now shape expectations of what high-quality credits look like:

1. Integrity Council for the Voluntary Carbon Market (ICVCM) – Core Carbon Principles (CCPs)

The CCPs define 10 principles covering environmental integrity, quantification, and governance. Credits meeting these standards are eligible for the CCP label, signifying a high bar of quality.

  • Assessments are rolling out by methodology type (e.g., forestry).

  • Only a small share of credits in today’s market are expected to earn this label—underscoring its selectivity.

2. Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA)

Launched by ICAO, CORSIA requires airlines to offset emissions above 2019 levels using only credits that meet strict criteria.

  • Credits must be high quality, additional, and transparently accounted for.

  • Corresponding Adjustments ensure no double counting under the Paris Agreement.

  • While aviation-focused, CORSIA raises expectations across the market.

3. Paris Agreement Article 6.4 Mechanism

This UN-led mechanism introduces some of the highest integrity standards yet. Credits must meet rigorous criteria for additionality, baselines, leakage, and safeguards.

  • Provides a centralized system with strong oversight.

  • Designed to give buyers full confidence that credits represent genuine climate outcomes.

Do These Standards Cover Everything?

Not entirely. Many innovative or smaller-scale projects—such as mangrove restoration or clean cooking solutions—may not yet carry CCP, CORSIA, or Article 6.4 approvals, even if they exceed key quality thresholds.

This is why relying solely on labels can lead to missed opportunities. A nuanced approach is essential.

How to Source High-Integrity Credits

Step 1: Check integrity labels

See if credits are CCP-labelled, CORSIA-eligible, or transitioning under Article 6.4.

Step 2: Use expert tools and analysis

Manually checking registries is time-consuming. Platforms like Sentinel Earth streamline the process, combining registry data with expert oversight to surface the most credible options.

Step 3: Apply a due diligence framework

Labels are a filter, not a guarantee. Buyers should:

  • Review project documents and third-party verifications.

  • Align purchases with internal climate strategies.

  • Consider co-benefits such as biodiversity or community impacts.

  • Benchmark against recognized quality frameworks.

The Road Ahead

The integrity landscape is evolving quickly. For buyers, this creates both opportunity and risk: the opportunity to invest in projects with measurable climate benefits, and the risk of being left behind if quality isn’t prioritized.

At Sentinel Earth, we help organizations cut through the complexity. From sourcing high-integrity credits to building robust due diligence processes, our goal is to bring clarity, confidence, and impact to every stage of your carbon procurement journey.
