Greening of the operations of the ports and the vessels by 2030/2047, one of the main goals of the Ministry of Ports, Shipping and Waterways, has been included in the Harit Sagar Guidelines. This also includes the target of harnessing  60% energy from renewables by 2030. According to the environmental regulations of the International Maritime Organization (IMO), ships are to be constructed with an immediate reduction in greenhouse gas (GHG) emissions of 15%, then 20% by 2020, and 30% by 2025. Adopting renewable energy (RE) in ports would also contribute towards achieving the non-fossil fuel energy capacity of 500 GW by 2030 with 50% contribution from RE. This is in accordance with our honourable Prime Minister’s announcement at the COP26.

Port activities are broadly bifurcated into operations of port and the movement and anchoring of ships. The power requirements of the two types of activities are met by the bunker oil a hydrocarbon emitting carbon dioxide.
