Whether it's South Asia Gateway Terminals or any other port hub, sustainability should be part and parcel of any clean air plan authorities formulate on the basis of the emissions inventory. Port operators should first compile their clean air strategies with specifics so the neighbouring communities, as well as port employees, are reassured that the plan will be completed within a given timeline. Progress should also be easy to track as communities will need demonstrations of good faith as the introduction of operational changes, equipment upgrades and switching to different types of fuel should take place with their support.
