The Carbon behind Cargo: Big Ships

When one of the biggest ships in the world got stuck in the Suez Canal, it threw a giant wrench into international supply chains. It exacerbated shortages of everything from semiconductors to snuggies. 

Journalist Maria Gallucci explains how this overlooked sector plays an essential part in supplying – and decarbonizing – the global economy. 

Lawyer and economist Aoife O’Leary covers our decarbonization tools, including new fuels, slow steaming and kites, plus the regulations to get us there. And don't forget the memes!

Guests: Aiofe O’Leary is the CEO of Opportunity Green. Maria Gallucci is a clean energy reporter at Canary Media and contributes to Grist and IEEE Spectrum
