I just goggled how dirty are container ships
This is what I got
The circa 50,000 container and cargo ships around the world pump out 900 million tonnes of CO2 each year (around 3% of total global emissions). And the 15 largest ships alone emit more nitrogen oxide and sulphur oxide (both potent greenhouse gases) than all the world's cars combined.
