Shemara Wikramanayake

Shemara Wikramanayake joined Sydney-based Macquarie in 1987 and spent the next three decades climbing her way to the role of managing director and CEO of the sprawling financial services firm. She's now facing plunging profits as the firm's once booming commodities trading unit faltered. The firm also earned less from selling green energy assets. Still, Wikramanayake remains upbeat about the transition to renewable energy.
