ICVCM Approves GCC Standard And Sets Tougher Conditions For Carbon Credit Integrity

ICVCM approved the Global Carbon Council Standard as CCP-Eligible, opening the door for eligible GCC methodologies to seek CCP labels.
Verra’s VCS renewable energy methodology gained conditional CCP approval, but only for projects that pass stricter additionality and financial viability tests.
ART TREES HFLD and Removals crediting levels require remedial action, leaving 58.4 million issued HFLD credits ineligible for CCP labels.

The Integrity Council for the Voluntary Carbon Market has issued a new round of assessment decisions that sharpen the line between eligible carbon credits and credits still facing integrity concerns.

The latest decisions cover carbon crediting programs and methodologies across renewable energy, forest protection, mangrove restoration, and methane abatement. Together, they push the voluntary carbon market toward stricter rules on additionality, baselines, uncertainty, and safeguard oversight.

The Global Carbon Council’s ICVCM Standard v2 has been approved as CCP-Eligible. Verra’s VCS renewable energy methodology has gained conditional approval. Isometric’s mangrove restoration protocol has also been approved. However, ART TREES v2.0 HFLD and Removals crediting levels must complete remedial actions before they can qualify.

Annette Nazareth, Chair of the Integrity Council, said: “This latest batch of decisions continues to demonstrate our commitment to independent, technical and thorough assessment of programs and methodologies for adherence to our high integrity CCP Assessment Framework. The difficult decisions we have taken to date are charting a path towards increased methodological rigour, as demonstrated by the approval of a new generation of more robust renewable energy methodologies.”

Global Carbon Council Gains CCP Eligibility

The Global Carbon Council, established in Qatar in 2016 by the Gulf Organisation for Research and Development, has secured CCP-Eligible status for its Standard on ICVCM Eligibility of Projects and Issuances v1.1.

The approval applies to projects that register under GCC 2.0 and follow the ICVCM eligibility standard, or later versions. GCC also added tighter rules on confidential information, non-permanence risk assessment, crediting period renewals, uncertainty, and safeguard procedures.

The decision does not mean all GCC credits automatically receive the CCP label. It allows GCC methodologies to enter ICVCM’s two-tick assessment process. Only credits issued under CCP-Approved methodologies and the relevant GCC standard will be able to carry the label.

Dr. Yousef Alhorr, Founding Chairman of the Global Carbon Council, said: “We welcome this landmark recognition from the ICVCM, which affirms the GCC Program’s standing as a high-integrity carbon crediting program on the international stage. We stand ready to deliver high-integrity carbon credits that are recognised and traded across international carbon markets, driving meaningful progress toward global climate goals.

For project owners and stakeholders, this approval provides access to a broader pool of high-quality buyers, stronger demand, and enduring market value for the credits they generate. We are proud to have reached this milestone and remain committed to advancing a transparent, efficient, and high-integrity voluntary carbon market that drives transformative climate action at scale.”

Verra Renewables Approved With Conditions

ICVCM also conditionally approved VCS VMR0017 v1.0, a Verra methodology for grid-connected renewable electricity generation. It covers wind, solar, geothermal, small-scale hydro, wave, and tidal power. Projects can also include battery energy storage and pumped storage under specified conditions.

The approval follows ICVCM’s July 2024 decision that several renewable energy methodologies failed to meet CCP criteria. At the time, the Council called for stronger approaches to additionality.

VMR0017 now meets the relevant criteria if projects use Verra’s updated additionality tool. A benchmark analysis must show that carbon credit revenue decisively improves project economics and meets or exceeds the financial viability benchmark.

ICVCM will not approve historical issuances for CCP labels. Still, the Council said strong market interest remains in high-integrity renewable energy projects and a large expected pipeline.

ART TREES Faces Remedial Action

ICVCM found that the ART TREES v2.0 HFLD Crediting Level does not currently meet the criteria for CCP Approval. HFLD activities cover areas with high forest cover and historically low deforestation.

The Governing Board has required ART to complete significant remedial actions. These include requiring participants to provide evidence that historical emissions significantly underestimate likely future emissions. Validation and verification bodies must then assess whether that evidence supports a threat of increased emissions in the first crediting period.

The decision is material for the market. Around 58.4 million credits have already been issued under the v2.0 HFLD Crediting Level. None are eligible for CCP labels.

ART TREES v2.0 Removals Crediting Level also failed to meet the current criteria. ICVCM has set remedial actions for that crediting level as well. No credits have yet been issued under the removals level.

For both categories, ICVCM must review whether the remedial actions have been implemented before any approval can be granted.

Mangroves And Methane Move Forward

ICVCM approved Isometric’s Mangrove Restoration Protocol v1.0. The methodology supports the recovery of degraded or lost mangrove ecosystems, with benefits for carbon storage and ecological function.

ICVCM cited the rigour of the methodology’s additionality test and dynamic baseline. Isometric published the protocol in December 2025. The company has three signed projects, with potential to issue up to 2 million carbon removal credits by 2030.

ICVCM also conditionally approved versions 6 to 8 of VCS ACM0008, which covers methane abatement from coal mines. The approval applies only to Ventilation Air Methane and Coal Mine Methane activities.

Projects must apply Verra’s updated baseline and additionality tool. Where a benchmark analysis is used, projects must show that carbon credit revenue decisively improves the economics of the abatement activity.

Projects have issued about 6.44 million credits under the approved methodology versions. However, ICVCM said the approval conditions mean few will likely qualify for CCP labels.

What Executives Should Take Away

For buyers, investors, and project developers, the latest ICVCM decisions raise the cost of weak claims. Eligibility now depends on stronger evidence, not program reputation alone.

The message is clear for corporate climate strategies. Credits tied to renewable energy, nature, and methane abatement may still play a role, but only where the underlying methodologies can survive tougher scrutiny.

For voluntary carbon markets, this is a governance reset. The CCP label is becoming a narrower filter for quality, and that could reshape demand, pricing, and procurement standards across global climate finance.
