The Bank of Thailand (BOT), the Hong Kong Monetary Authority (HKMA) and Hong Kong Exchanges and Clearing Limited (HKEX) have released the results of a proof-of-concept initiative exploring how digital currencies and tokenisation could improve cross-border carbon credit transactions. The collaboration brought together Thailand’s Project San and Hong Kong’s Project Ensemble to examine how interoperable financial infrastructure could support more efficient and transparent carbon markets. Details of the initiative were published in the official project announcement.
The project focused on the growing role of carbon markets in supporting the transition to a low-carbon economy. Carbon credit trading channels investment into projects designed to reduce greenhouse gas emissions or remove carbon from the atmosphere. However, international transactions often involve multiple intermediaries, fragmented systems and differing regulatory environments, creating operational complexity and slowing transaction processes.
Testing tokenisation for cross-border carbon trading
The proof-of-concept explored the use of tokenisation, where financial assets are represented digitally on programmable infrastructure. According to the participating authorities, the testing demonstrated that combining tokenised transactions with stronger connectivity between financial systems could reduce friction in the trading process and improve operational visibility.
The participating institutions said the approach enabled faster tracking of transaction status and improved transparency for cross-border carbon credit exchanges. These capabilities are viewed as increasingly important as governments and financial authorities seek to support sustainable finance initiatives while maintaining oversight and interoperability across jurisdictions.
The initiative also reflects wider regional efforts to modernise financial infrastructure through digital technologies. Thailand has recently expanded its broader digital public infrastructure through initiatives such as the country’s digital ID infrastructure linking government e-services, aimed at improving access and interoperability across public systems.
Supporting sustainable finance through interoperable systems
The findings highlighted the potential value of interoperable financial infrastructure capable of connecting different platforms and jurisdictions. Central banks globally are examining how digital settlement systems and tokenised assets could support new forms of financial activity, including sustainability-linked transactions and cross-border payments.
For carbon markets, interoperability is particularly significant because transactions frequently span several countries and involve multiple market participants. Fragmented infrastructure can increase processing times, reduce transparency and create additional administrative requirements. The project partners indicated that digitally connected systems may help streamline these processes while supporting clearer audit trails.
The collaboration between Thailand and Hong Kong also demonstrated the importance of coordination between central banks, financial service providers and businesses when developing future financial systems. The participating organisations stated that cooperation across sectors will be necessary to establish standards and governance frameworks that allow digital finance initiatives to scale securely.
Regional digital finance development continues
The proof-of-concept forms part of broader experimentation across Asia involving digital assets, financial infrastructure modernisation and sustainable finance. Authorities in several jurisdictions are assessing how emerging technologies can support policy objectives related to efficiency, resilience and environmental transition.
Thailand has increasingly positioned digital innovation as part of its wider economic and industrial development agenda. Alongside financial sector modernisation, the country has been investing in technical capabilities linked to advanced manufacturing, artificial intelligence and semiconductor development, including initiatives where metrology supports AI, electric vehicle and semiconductor growth.
While the project remains at the proof-of-concept stage, the published results provide insight into how tokenisation and connected digital infrastructure could contribute to future cross-border financial ecosystems. The participating authorities said the testing demonstrated how financial innovation could support both digital finance development and sustainability objectives through closer infrastructure integration and international collaboration.
