India’s aspiration to enhance its maritime strength is evident along its extensive 7,500-kilometre coastline. Formerly basic trade gateways, ports have transformed into bustling centers of economic activity, facilitating India’s industrial growth, exports, and global competitiveness. The pressing concern now is how to sustain this growth without jeopardizing fragile coastal ecosystems and exacerbating climate change.
Recognizing the urgency, India is embracing green growth as the key to sustainable development. Ports, crucial for handling 95% of the country’s external trade volume, have witnessed a significant surge in cargo over the past decade, reflecting increased manufacturing and global supply chain integration. However, this growth has also brought challenges such as air pollution, water contamination, and carbon emissions, particularly in proximity to sensitive coastal environments and densely populated cities.
A notable shift is underway with the enactment of the Indian Ports Act, 2025, replacing the outdated Ports Act of 1908. This legislative change embeds environmental safeguards into the governance structure, making sustainability a fundamental requirement rather than an optional consideration. Long-term planning now aligns port expansion with climate responsibility, exemplified by the Maritime India Vision 2030 and the Harit Sagar Green Port Guidelines, which establish clear sustainability objectives.
The vision for 2030 mandates ports to reduce carbon emissions per cargo ton by 30%, transition a significant portion of equipment to electric power, and source over 60% of energy from renewable sources. These targets are set to progress further by 2047, emphasizing the continuous nature of the green transition. Ports are also adopting cleaner operational practices, such as shore-to-ship power systems to minimize air pollution and electrified equipment to enhance safety and efficiency.
Efforts are underway to address water management and biodiversity conservation, focusing on wastewater recycling, reduced discharge, and beneficial reuse of dredged materials. Initiatives like mangrove restoration and increased green cover aim to mitigate carbon emissions, safeguard shorelines from climate-induced risks, and enhance resilience against storms and erosion. These sustainability measures not only benefit the environment but also positively impact local communities affected by port activities.
