Secretary for Financial Services & the Treasury Christopher Hui today welcomed the signing of a Memorandum of Understanding (MoU) among Hong Kong Exchanges & Clearing (HKEX), the Guangzhou Emissions Exchange, Shenzhen Green Exchange and Macao International Carbon Emission Exchange.

The MoU aims to further promote knowledge exchange and sharing, and strengthen collaboration in the development of carbon markets and the green finance ecosystem in the Guangdong-Hong Kong-Macao Greater Bay Area (GBA).

Mr Hui said the Government attaches great importance to carbon markets in the GBA and actively promotes co-operation with them.

“As the first quadripartite agreement among the carbon exchanges within the GBA, this MoU marks new heights in the orderly and healthy collaborative development of the GBA's carbon markets.”

The 2025 Policy Address proposed deepening pilot co-operation with the GBA carbon market, jointly building a regional carbon market ecosystem.

Mr Hui said the signing of the MoU among HKEX and several GBA carbon exchanges fully demonstrates the determination of the Government and HKEX in the continuous active promotion of co-operation and joint development with Mainland carbon markets through various means, consolidating Hong Kong's position as a leading sustainable finance centre in the region.

Core Climate, HKEX's international carbon trading platform, is the only voluntary carbon credit trading platform in the world offering settlement in Hong Kong dollars and Renminbi.

In addition to deepening co-operation with the GBA carbon market, the 2025 Policy Address also announced that the Government will work with relevant Mainland regulatory departments and authorities to study issues surrounding the country's participation in the international carbon market.

The Government and HKEX will continue to work closely with relevant stakeholders to jointly enhance the carbon market ecosystem.
