Corporate
27 Jan 2026

Hong Kong Exchanges and Clearing Limited (HKEX) is pleased to announce today (Tuesday) it has signed a Memorandum of Understanding (MOU) with B3, Brazil’s stock exchange operator, to promote sustainable finance and the development of carbon markets in their respective regions.

The MOU underscores HKEX’s commitment to supporting the global transition to a low-carbon economy, and extends the Group’s sustainability partnerships to South America, a region of significant importance to global climate solutions.

Under the agreement, HKEX and B3 will work together to advance carbon market development and explore opportunities in commodities in Hong Kong and Brazil, and will establish regular communication channels to deepen collaboration. The two exchanges will also explore potential for cross listings of equities in HKEX and B3, while identifying new carbon and ESG product opportunities across Asia and South America.

HKEX Chief Sustainability Officer, Paul Chow, said: “We are delighted to enter into this MOU with B3, a global leader among financial market infrastructure groups. This partnership builds on the foundation we’ve established through our carbon marketplace, Core Climate, and underscores HKEX’s ongoing commitment to advancing sustainable finance across regions globally. We look forward to working closely with B3 to support the continued development of international carbon standards, encourage innovation and drive meaningful progress towards a low-carbon economy through cross-border collaboration.”

B3 Director of International Business Development for Asia and Oceania, Sérgio Gullo, said: “Cooperating with HKEX strengthens B3’s position as a driving force in the transition to a sustainable economy, while opening new opportunities for the Brazilian market in the international arena. Expanding our international presence positions us within the global sustainable finance market and enables companies to access ESG products. B3 remains committed to fostering an innovative, transparent, and sustainable business environment, contributing to the development of solutions that combine economic growth with environmental responsibility.”

HKEX is committed to expanding its sustainable finance footprint and helping to develop transparent, inclusive, and globally connected carbon markets. By deepening ties with B3 and expanding its sustainable finance initiatives, HKEX is further positioning itself as a connector of markets, fostering innovation and cross-border collaboration to build a more resilient and inclusive financial ecosystem.
