The Sustainability Committee consists of three (3) Directors.

The Sustainability Committee meets regularly to review the strategic direction and priorities of Antin’s Sustainability strategy, monitoring sustainability progress at all levels of the organisation and formulating recommendations on relevant sustainabilityrelated matters. More specifically, the Committee is responsible for overseeing the implementation of Antin’s Responsible Investment Policy, thereby ensuring that sustainability issues are properly integrated in investment processes and actively managed at the portfolio company level throughout the holding period.
