Ahead of London International Shipping Week 2021, a six-part S&P Global Platts podcast series looks into the pricing of alternative marine fuels for the global shipping industry. In each episode of Marine Fuels of the Future, Platts editors investigate the current state of the major fuel alternatives, as the shipping sector seeks to reduce its greenhouse gas emissions ahead of stringent caps in 2030 and 2050. In episode two, we look at biofuels – a diverse energy source derived from vegetable oils and waste matter, rather than from traditional hydrocarbons.
