Cynthia Shih is the climate change activist and Director of Knowledge at mckinsey.org who’s helping to redefine what recycling means for the 21st century. But you might also know her as touring and recording artist Vienna Teng. Cynthia longed to be making more of a direct, positive impact on the planet, so she ditched the tour bus to tackle a dual Master’s degree, because she’s convinced there’s more than one way to fight climate change. It doesn’t just come from the world of business or from people taking to the streets or from songwriting. Cynthia talks about how being a musician and a management consultant gives her a unique perspective on the world’s problems, the pros and cons of feeling like an outsider and why her colleagues call her the “Cynthia-sizer”.
