Driving Green Finance Innovation in Hong Kong: Xeptagon Completes Three Climate FinTech POCs
• Published 8:00 AM EDT, THU Oct 09, 2025
As Hong Kong continues its journey to become a global hub for Green and Sustainable Finance, Xeptagon has successfully completed three Proofs of Concept (POCs) under the Green FinTech initiative sponsored by the Financial Services and the Treasury Bureau (FSTB) and administered by Cyberport Hong Kong.
The three projects — focusing on Carbon Credit Management, Real-Time Carbon Trading, and CBAM Supply Chain Transparency — highlight how digital innovation can accelerate carbon neutrality, enhance regulatory alignment, and strengthen Hong Kong's position as a leader in sustainable finance.
These initiatives were sponsored by Schneider Electric, Tessellation Group, and ThinkESG Limited, bringing together world-class expertise in energy management, sustainability strategy, and ESG advisory.
Xeptagon presented these POCs during Hong Kong Green FinTech Week at Cyberport, where they received strong interest from regulators, investors, and financial institutions for their potential to power future carbon markets.
Recognition and Impact
Xeptagon was selected as a finalist in the 2025 HKMA Green FinTech Competition under Theme #3: Carbon Market Analytics and Technology, organised by the Hong Kong Monetary Authority in partnership with KPMG.
This recognition places Xeptagon among the leading Green FinTech innovators driving carbon market and sustainability data infrastructure in Hong Kong. The company is also featured on the Hong Kong Green FinTech Map, highlighting its role in developing regulatory-aligned, technology-driven platforms for global carbon markets.
As part of its ongoing engagement, Xeptagon is preparing for a Landmark pilot carbon transaction, which will be showcased at Hong Kong FinTech Week (HKFTW) 2025 to demonstrate how tokenised credits can be traded transparently through blockchain-connected registries and exchanges.

From the issuance to certification to transfer and all the way to retirement.
The platform is integrated with blockchain technology to ensure data integrity, all data are immutable and transparent and at the same time aligns with UNDP, World Bank & UNFCCC Standards. By automating MRV process and the seamless connection with online exchanges, the project provided a simplified way to carbon credit management and at the same time reduced operational risks.
2. Real-Time Carbon Trading System
The Real-Time Carbon Trading System provides a digital carbon exchange and marketplace, with seamless registry connectivity to support real time carbon credits trading and settlements. The system consists features of spot trading, auctions and OTC transactions along with advanced trading mechanisms such as Limit & Market Orders with stop losses. Through blockchain backed data records, the system brings immutability, transparency and ensures regulatory compliances, resolving the current challenges of fragmented and inefficiency.
This initiative allows large organizations to launch and participate in the carbon market in an easy and secured way. It also paves a way for Hong Kong in becoming the carbon exchange hub in Asia and even around the world, providing enterprises and organizations with reliable and quick access to different variety of high quality credits through a digital automated process.
3. CBAM Supply Chain Transparency System
With the EU Carbon Boarder Adjustment Mechanism (CBAM) coming into full effect by the end of 2025, manufactures who are exporting to Europe are required to measure, verify and report their carbon emissions of their products throughout the supply chain.
The CBAM Supply Chain Transparency System POC brings a blockchain based system that could be used to assist manufactures to maintain continuous visibility across their supply chain. Integrated with Schneider Electric’s emission estimation system, the system brings accurate scope 1, 2 and 3 emission data, allowing organizations to meet the compliance and at the same time keeping the data confidential.
By offering an automated solution for emission tracking & management, MRV and reporting, this POC supports sustainable manufacturing and transparent supply chain, helping organizations in operating responsibly and competitively towards carbon neutrality and ESG excellence.
