Just one super ship emits as much sulphur in one year as 50 million cars (it takes just 16 ships to emit as much as all of the automobiles in the world). These ships regularly idle unnecessarily outside of ports around the globe, contributing significantly to global warming and harming the health of nearby cities. This project will create a dedicated online portal that provides more than 3,000 ports around the world with access to data about ship idling and related environmental impacts. The portal will empower trade associations, governments, the shipping sector, and the general public to take action for a healthier environment.
