• New marketplace connects verified Environmental Attribute Certificate (EAC) supply with global corporate demand across multimodal transport sectors
• Platform enables forward financing of decarbonization projects, including green corridors, by unlocking future EAC transactions
• Built on the 123Carbon registry and aligned with Smart Freight Centre frameworks and ISO 22095 Book and Claim standards, reducing double counting risk and improving market integrity

Carboninsets has launched a global digital marketplace aimed at accelerating decarbonization in hard-to-abate sectors, starting with transport. The platform connects buyers and suppliers of verified Environmental Attribute Certificates across aviation, shipping, road freight, rail, and logistics hubs.

The move addresses a longstanding barrier in transport decarbonization: fragmented solutions and limited comparability across fuels, technologies, and geographies. By centralizing access to verified certificates, Carboninsets is positioning EACs as a scalable tool for companies seeking measurable emissions reductions across supply chains.

The marketplace aggregates supply from fuel producers and fleet operators, enabling real-time visibility into pricing and availability. Buyers can assess certificates based on emissions impact, feedstock, geography, and technology type, offering a level of transparency that has been largely absent in voluntary transport decarbonization markets.

Financing the Next Wave of Low-Carbon Infrastructure

Beyond spot transactions, the platform introduces a forward-looking mechanism critical for scaling climate infrastructure. Companies can commit to future EAC purchases tied to projects that are not yet operational, such as green shipping corridors or sustainable aviation fuel supply chains.

This model effectively channels corporate demand into project financing, offering developers greater certainty while allowing buyers to secure future emissions reductions aligned with long-term climate targets.

The ability to transact on both current and future supply positions the marketplace as more than a trading venue. It becomes a capital allocation tool, linking corporate climate commitments directly to infrastructure development.

Standardization and Market Integrity

All certificates listed on the platform are issued via the 123Carbon registry and independently verified by accredited auditors. The registry operates under globally recognized frameworks, including the Smart Freight Centre Market Based Measures guidance and ISO 22095 for Book and Claim systems.

This alignment addresses one of the most persistent concerns among corporate buyers and investors: credibility. Each EAC represents a quantified lifecycle emissions reduction, supported by traceable data and third-party validation. Safeguards against double counting are embedded within the registry infrastructure.

For multinational companies navigating Scope 3 emissions, particularly in logistics-heavy supply chains, these assurances are increasingly non-negotiable.

Industry Voices: Unlocking Liquidity and Scale

Maria Lacalle Muls, Head of Customer Decarbonization at Carboninsets, said: “Decarbonizing hard-to-abate sectors such as transport has been constrained by the poor comparability and the fragmentation of emission reduction solutions. Book & Claim solves this issue. The Carboninsets marketplace unlocks live access to available EACs volumes by creating a practical solution to accelerate decarbonization.

“Carboninsets has already started to onboard the 30+ issuers that have jointly issued over 500.000 EACs in the 123Carbon Registry, across all transport modalities and geographies. In a nutshell, our new marketplace enables companies to access current and future offers of EACs in the most transparent way, helping turn decarbonization commitments into immediate action”.

Jeroen van Heiningen, managing director at 123Carbon, said: “This one-of-a-kind marketplace provides issuers of the 123Carbon registry with an additional sales channel that they can manage directly from their existing inventory. It also gives them direct access to global demand beyond their existing customer base.”

What It Means for Executives and Investors

For C-suite leaders, the platform introduces a practical pathway to act on climate commitments in sectors where direct emissions reductions remain technologically or economically constrained. It offers a standardized mechanism to procure verified reductions without waiting for full operational decarbonization.

For investors, the implications extend to market structure. By improving liquidity, transparency, and standardization, the marketplace could accelerate capital flows into alternative fuels and logistics decarbonization projects. It also strengthens the case for Book and Claim as a scalable model for Scope 3 mitigation.

Global Implications

As regulatory pressure intensifies and voluntary carbon markets face scrutiny, the emergence of verified, sector-specific instruments like EACs signals a shift toward more granular and accountable climate action. Transport remains one of the most challenging sectors to decarbonize globally.

Platforms that can bridge demand, supply, and financing at scale are likely to play a defining role in how quickly that transition unfolds.
