> Cargo ships are a massive CO2 contributor Not really. They’re 1.6% of global emissions if I multiplied the numbers on this page out right. The table says they’re 20% of shipping emissions, and the intro says shipping is 8% of global emissions (excluding ports and warehouses). This result seems surprising until you realize that semi trucks produce 100x more CO2 per kg-mile of cargo. https://climate.mit.edu/explainers/freight-transportation https://climate.mit.edu/explainers/freight-transportation
