Sustainability Leadership Council

GBTA’s Sustainability Leadership Council (SLC) is set up as an advisory body to the GBTA Foundation. It actively guides and shapes the Foundation’s efforts to build a greener future for business travel. Council members bring deep sustainability experience and are nominated by their company to serve a one-year calendar term. They help guide GBTA’s efforts, define priority areas for collaborative and global action, raise the bar for the business travel industry overall, and identify significant contributions the sector can make to climate action and corporate responsibility.
