At the turn of the millennium, the UN launched its Global Compact, an ambitious endeavour to encourage companies around the world to adopt socially and environmentally sustainable policies. One of the first names on the team sheet was technology giant Lenovo. Ever since, as the company has ballooned in size, it has released a comprehensive annual Environmental, Social and Governance (ESG) report to hold itself publicly accountable against its sustainability targets. Mary Jacques leads the company's efforts in this area as Executive Director, Global ESG and Regulatory Compliance. Her career with Lenovo stretches almost as far back as that original compact, and in every role her focus has been sustainabilty and the environment. It was the same in roles at MIT and IBM before that, and in academia where she studied environmental science. In this episode we discuss Lenovo's progress to date, the challenges that remain, and the lessons we can all learn to continue to advance the sustainabilty cause.
