Singapore-headquartered global carbon market solutions provider Climate Impact X (CIX) has appointed Oi-Yee Choo as its chief executive officer, effective October 21, when she will take over from interim CEO Mark Glossoti, who will now return to his role as chief operating officer.
Choo is a seasoned business leader with 25 years of experience in financial markets. She has built and led high-performing businesses across sectors, with a proven track record in fintech, innovation and capital markets.
She was most recently CEO of ADDX, a blockchain-based private capital markets exchange in Singapore licensed and regulated by the Monetary Authority of Singapore. Under her leadership since 2020, ADDX strengthened its partnerships with global blue-chip companies and grew its platform to surpass US$1 billion in tokenized securities, one of the largest worldwide. Prior to ADDX, Choo spent over 20 years in investment banking, leading major capital markets transactions for clients across Asia, Europe and the US. She has held leadership roles at Citigroup, Morgan Stanley, Nomura and UBS.
CIX also announced that Claire O'Neill, a member of its board since 2022, will assume the role of board chair, effective November 1. This transition marks a strategic shift from the rotational chairperson system previously in place. O’Neill takes over from Bill Winters, group chief executive of Standard Chartered and the current board chair.
She brings a wealth of experience spanning over three decades in both the private and public sectors. A former UK minister and today a global expert on sustainability and decarbonization, her expertise in policy, international business development, and her extensive global network, the company says, will continue to play a pivotal role in shaping its strategic direction.
O'Neill was a UK member of parliament from 2010 and minister of state for energy and clean growth from 2017, where she played a key role in the acceleration of the country’s decarbonization strategies. She left politics in 2020 to join the World Business Council for Sustainable Development.
The appointments represent a natural evolution for the company, it states, offering a balanced leadership that combines regional expertise with a truly global outlook. As CEO, Choo will also be appointed to the CIX board as a director when she assumes her new role.
“Choo brings a track record of success in leadership roles, strong commercial acumen and exceptional experience in scaling high-performing businesses,” Winters says. “Her fresh perspective, combined with a deep understanding of fostering robust ecosystems, will be instrumental as CIX enters its next phase of growth.
“Collectively, Choo, O'Neill and the CIX leadership team offer highly complementary expertise and skills, which will no doubt amplify the capabilities that already exist within the company.”
