33. Is ESG investing good for biodiversity? (Ken Pucker)
06/05/23 • 46 min
ESG is the latest buzzword in business & biodiversity circles, but it’s not actually new - only newly popular. And it’s one among many terms and acronyms in this field, which may be familiar but are often poorly understood - ESG stands for “environmental, social and governance” investing criteria. Understanding concepts like ESG is consequential because their success relies largely on convincing the general public of their value and their virtue. As we discuss in this episode, however, they are not necessarily all that they’re made out to be.
To elucidate this topic with me is Ken Pucker. Ken is a professor at the Fletcher School at Tufts University and Advisory Director at the Boston-based Financial Services firm, Berkshire Partners. He was previously Chief Operating Officer of the outdoor footwear and apparel company, Timberland, one of the first companies to take an interest in sustainable production. He has written extensively on ESG and related issues in Harvard Business Review among other publications.

32. When should we question environmental orthodoxy? (Russell Galt)
There is a tendency in societies to adhere to conventional wisdom. We resist challenges to consensus views, and may even dismiss those who do challenge them as conspiracy theorists... which they sometimes are. But perhaps we take that idea too far sometimes. Perhaps we underestimate the importance of having the freedom to challenge orthodoxy. We live in an age in which more people than ever before are lucky enough to inhabit free societies, but recently it has become “conventional” to take issue with some of these hard-earned freedoms - albeit often with good intentions. Even people who don’t follow the news cycle must be familiar with the concepts of cancel culture and de-platforming. In this episode we discuss the notion of questioning orthodoxy, with a focus on the environment and especially conservation.
My guest is Russell Galt, Head of Policy and Science at Earthwatch Europe, and previously Senior Programme Coordinator of IUCN’s work on urban conservation and Young Champions of the Earth Coordinator with the United Nations Environment Programme. Russell recently complete a Master of Business Administration at the University of Edinburgh, to complement his earlier studies in ecology.

34. Is there still hope for the world’s corals? (Mike Emslie)
Historically, the oceans have received too little attention in discussions about the environment and biodiversity. On the topic of biodiversity loss in particular, however, one marine system has attracted almost as much attention as the rainforests: coral reefs. Coral reefs have even been described as the rainforests of the sea, thanks to their remarkably high levels of biodiversity. Recently, United Nations agencies have been voicing the alarming prediction that the world could lose as much as 99% of its corals within decades, if there is a 2 degree centigrade increase in average global temperature. Meanwhile, however, on the world’s largest reef system, the Great Barrier Reef, a 2021 survey had more positive news. It found that hard coral cover, which is used as a proxy for the health of coral reefs, is at its highest levels since the 1980s. That’s despite global temperatures already having risen by one degree over the past century. So, is the public being misled by messages of doom and gloom? Or are these seemingly contradictory messages somehow reconcilable?
With me to answer this central question about corals is Mike Emslie. Mike is head of the Great Barrier Reef Monitoring Programme and senior researcher at the Australian Institute for Marine Science (AIMS).
