Official Launch of the Macao International Carbon Emission Exchange (MEX) Trading Platform

Official Launch of the Macao International Carbon Emission Exchange (MEX) Trading Platform

On October 10, 2025, the new-generation green asset trading platform developed by the Macao International Carbon Emission Exchange (MEX) was fully launched.

Since its pilot operation following MEX's inauguration, the platform has undergone multiple rounds of technical refinement and market adaptation. Verified through systematic trial operation and technical iterations, it has successfully entered a new phase of large-scale operation. The platform enables end-to-end digital closed-loop trading of diverse environmental products such as carbon credits and green power certificates, with leading daily processing capacity and response time control. Its trading efficiency is significantly higher than that of traditional OTC markets, providing an "efficient, credible, safe and controllable" digital solution for the high-quality development of global carbon markets.

Adhering to the core design concept of "full-scenario service and full-link efficiency", the platform builds a functional closed loop to address industry pain points.

In terms of trading scenarios, it covers the contract market, retail market, and auction market. The contract market supports continuous bidding for standardized carbon credit contracts, meeting the large-volume and high-frequency trading needs of institutional investors; the retail market provides 24/7 uninterrupted services to lower the threshold for small-volume transactions; the auction market allows bidding for carbon credits and green energy certificates based on orders, supporting multiple bidding methods. In terms of fund settlement, smart contracts automatically trigger clearing and settlement, enabling real-time T+0 fund crediting and supporting automatic settlement in multiple currencies including RMB, Hong Kong dollars, and US dollars, further improving fund circulation efficiency and settlement accuracy. During the pilot phase, the platform has completed over 1 million tons of carbon credit transactions, covering multiple emission reduction fields such as wind power, hydropower, and biomass energy.

The official launch of the platform will build a bridge for the circulation of green assets between China and the world, further open up channels for international carbon asset circulation, and facilitate the process of global carbon market integration.

Notably, the newly launched trading platform will operate in synergy with MEX's previously initiated "Carbon Trading BlockChain" program, the first initiative focusing on high-quality carbon credits. This forms a dual-track development pattern of traditional trading platforms and Web3 carbon infrastructure. This layout not only enhances trading efficiency and transparency but also realizes the traceability authentication and credible circulation of carbon assets through blockchain technology, constructing a new "on-chain + off-chain" integrated ecological system for global carbon markets. The coordinated development of the two types of platforms will jointly inject innovative momentum and technological support into achieving the emission reduction goals of the Paris Agreement and promoting global green and low-carbon transition.
