'Net zero’ was a buzzword in the sustainability world in 2021, but big questions remain about what this term really means. In this episode of ESG Insider, we'll hear how the Science Based Targets initiative, or SBTi, is defining net zero in its newly released corporate standard. And to understand the challenges the financial sector faces in defining and achieving net zero targets, we talk to Curtis Ravenel, who is senior adviser to Mark Carney — the former Bank of England Governor who now acts as U.N. special envoy on climate finance.  We'll also hear from Jeanne Martin, senior campaign manager at U.K.-based investor activist group ShareAction, about where European banks stand and why they need to make significant progress toward their net zero goals by 2030.   To learn more about the extent to which big corporations in multiple sectors are setting net zero targets, read an analysis by S&P Global Market Intelligence:  https://www.spglobal.com/marketintelligence/en/news-insights/latest-news-headlines/path-to-net-zero-stakeholders-demand-action-on-ambitions-as-pledges-swell-67951124 Photo credit: Getty Images
