He spent a decade as a renewables executive. This week on Zero, Bloomberg Green Executive Editor Aaron Rutkoff talks to Senior Reporter Akshat Rathi about his new in-depth profile of Al Jaber explor...

Mar 16, 2023•30 min•Ep 31•Transcript available on Metacast If you’ve got the technology that can change the world, are you the best person to implement it? Investors pay careful attention to the CEO of any company, but in climate tech, they deserve special scrutiny – much of the science has never been brought to scale and they are competing against the status quo, massive trillion-dollar industries. It takes business acumen to launch a profitable business and the stakes are high, so some investors prefer a seasoned entrepreneur to a scientist. Bloomberg...
Mar 09, 2023•29 min•Ep 30•Transcript available on Metacast Since the Human Development Index was established in 1990, it has trended gradually upward, as people’s health, wealth and opportunities have improved. But in 2019, it went into a decline then made worse by the COVID-19 pandemic and the fallout from the war in Ukraine. The impacts of these events on reversing human progress could be dwarfed by climate change, says Achim Steiner, head of the United Nations Development Programme. However, the solutions to the climate problem also offer the potenti...

Instead, it’s become a protracted war with impacts felt far and wide — disrupting food systems, supply chains, geopolitics and the global economy. Europe’s most remarkable response to the war isn’t to do with sending in tanks or billions of dollars in aid to Ukraine. Instead, it’s been the surprising speed with which it has ditched Russian fossil fuels and strangled the source of funding for Russia’s war machine. In...

Nov 22, 2022•31 min•Ep 16•Transcript available on Metacast Lewis Pugh has swum across seas and in between melting sea ice, but the hardest part of his work is what comes after – contributing to negotiations to protect those same bodies from development. And he’s been successful: In 2016 he got the Russians to sign a pact to create a marine protected area in the Ross Sea – one of the few healthy seas left, and the size of Britain, France, Germany, Italy put together. A negotiation should be an exploration, not a battle, he tells Akshat Rathi. Pugh also t...
