The minute
- Singapore-based Climate Impact X (CIX), launched in 2021 by DBS, Singapore Exchange (SGX), Standard Chartered and Temasek, will combine with London-based Carbonplace, founded by banks including CIBC, Itaú Unibanco, National Australia Bank and NatWest
- Integration is expected to complete in Q1 2027, with both brands maintained during the transition; Oi-Yee Choo becomes CEO and Scott Eaton President
- The combined platform promises to cover the full carbon credit transaction lifecycle, from portfolio strategy to project sourcing, multi-registry access, settlement, custody and retirement
Why it matters: Joining Singapore’s carbon services ecosystem with London’s institutional capital is a bet on “robust, trusted” infrastructure that works for both voluntary and compliance markets, across different time zones at once. The fact that banks from different continents (Asian, European and Latin American, with Itaú Unibanco among Carbonplace’s founders) are behind these platforms shows major financial institutions now treat carbon market infrastructure as a long-term strategic bet, not a side experiment.
Who is in the combined shareholder group
The merger brings together a roster that goes well beyond the original founding banks. The combined shareholder group now includes BBVA, BNP Paribas, CIBC, DBS Bank, GenZero, Mizuho Financial Group, National Australia Bank, NatWest Group, SGX Group, Standard Chartered, Sumitomo Mitsui Banking Corporation (SMBC) and UBS. Several of these, including UBS, BNP Paribas, BBVA and SMBC, joined Carbonplace as founding banks in 2022, a year after its initial launch.
The presence of Mizuho and SMBC (Japan), BBVA (Spain), BNP Paribas (France) and Itaú Unibanco (Brazil) alongside Australian, British, Canadian and Singaporean institutions means the merged entity starts with bank relationships spanning every major carbon-trading time zone.
What each side actually brings to the table
CIX and Carbonplace were built to solve different parts of the same problem, which is why the merger creates a single pipeline rather than a redundant overlap.
CIX operates exchange infrastructure for carbon credits and renewable energy certificates (RECs), plus a growing suite of related environmental products. Its stack leverages satellite monitoring, machine learning and blockchain to verify the transparency, integrity and quality of credits before they reach the marketplace. In practical terms, CIX covers procurement, trading and price discovery.
Carbonplace, on the other hand, built multi-registry infrastructure and a direct ownership model with bank-grade settlement. It provides carbon portfolio management for corporate buyers and carbon inventory management for project developers, connecting both sides through a global transactions network. As Scott Eaton put it in the merger announcement: “A trade is only as good as the infrastructure that completes it, knowing a credit has genuinely changed hands, can be held securely and retired with a clear audit trail.”
Once integrated, a participant could source credits through CIX’s exchange, settle the transaction through Carbonplace’s registry-connected rails, hold the credits in custody under a verified ownership record, and retire them with a full audit trail, all within one combined platform.
The Brazil connection
Itaú Unibanco’s role as a Carbonplace founder is worth watching in the context of Brazil’s evolving carbon market. Brazil established its regulated emissions trading system, the SBCE (Sistema Brasileiro de Comércio de Emissões), through legislation signed in late 2024. The system is still in its implementation phase, with regulators defining which sectors fall under mandatory caps and how offsets will interact with compliance obligations.
For Brazilian operators, the merger matters because Carbonplace’s multi-registry access could eventually provide a bridge between credits generated under Brazil’s domestic framework and international buyers accessing the platform through London or Singapore. Having a major Brazilian bank embedded in the platform’s governance, not just as a client, gives the merged entity a direct channel into Latin America’s largest carbon market as its rules take shape.
The common mistake this merger tries to fix
The most frequent failure in voluntary carbon transactions is not fraud (though that gets the headlines). It is fragmentation. A buyer finds credits on one platform, verifies them against a registry hosted elsewhere, settles payment through a third channel, and retires the credit by manually submitting paperwork to yet another system. Each handoff introduces delay, reconciliation errors and the risk that the same credit is counted twice before retirement is confirmed.
Claire O’Neill, Board Chairperson of CIX, framed the merger around exactly this gap: the combined company will offer “common market infrastructure that simplifies access to a fragmented carbon market” alongside “trusted access to a full suite of environmental product solutions.”
Coverage of the deal by CarbonCredits.com frames the same point from the market side: carbon trading is still split across regions and platforms, which limits liquidity and price transparency, and a merger between an Asian exchange and a European settlement network is a step toward the connected marketplace that institutional buyers and sellers need to scale. via CarbonCredits.com
What is still unresolved
The merger announcement leaves several questions open. First, how the two technology stacks will be unified (CIX’s blockchain-based verification alongside Carbonplace’s bank-grade settlement layer) has not been detailed beyond a Q1 2027 target. Second, whether the merged platform will seek formal recognition under compliance schemes (such as the EU’s Carbon Border Adjustment Mechanism or Singapore’s carbon tax framework) or remain focused on voluntary markets will determine its long-term scale. Third, the interaction between Carbonplace’s direct ownership model (where the buyer holds the credit, not an intermediary) and CIX’s exchange-traded model (where credits may change hands multiple times before retirement) still needs a unified legal and operational framework.
The shareholder group has the capital and the geographic reach. Whether the integration delivers a genuinely unified pipeline, or two platforms sharing a logo, depends on the technical and regulatory work that happens between now and early 2027.
