Nautilus Labs closed $34 million in funding from investors including the Microsoft Climate Innovation Fund. The company plans to use its funding to improve shipping industry efficiency with its software. Nautilus CEO Matt Heider joined Cheddar News to talk about how it tackles the carbon emissions in the global supply chain. "We've seen on 10-day voyages saving $60,000 worth of fuel just by managing speed with greater confidence around the future. The environmental impact of that is also huge," he said. "Saving that amount of fuel is a kind of taking over 1000 cars off the road this year."
