India’s ambition to emerge as a strong maritime power is no longer confined to long-term policy documents but is increasingly visible along its 7,500-kilometre coastline, according to an India Narrative report. Ports that once served as modest trade gateways have evolved into bustling economic hubs, handling rising cargo volumes and underpinning the country’s push for manufacturing, exports and global competitiveness.
However, as port-led growth accelerates, sustainability has moved to the centre of policymaking. With ports handling nearly 95 per cent of India’s external trade by volume, their environmental footprint has become impossible to ignore. Cargo handled at major ports has risen sharply over the past decade—from around 581 million tonnes to nearly 855 million tonnes—reflecting deeper integration with global supply chains. At the same time, ports remain significant sources of air pollution, water contamination and carbon emissions, often located close to fragile ecosystems such as mangroves, wetlands and coral reefs, as well as densely populated coastal cities.
The report notes that India is increasingly viewing green growth not as a constraint but as the only viable path to sustainable maritime development. A key inflection point has been the replacement of the colonial-era Ports Act of 1908 with the Indian Ports Act, 2025, which embeds environmental safeguards directly into maritime governance. Sustainability is now a legal requirement rather than a voluntary add-on.
This shift is reinforced by long-term planning frameworks such as the Maritime India Vision 2030, which places sustainability at the core of port-led development. The vision is supported by the Harit Sagar Green Port Guidelines, which set measurable targets for reducing the sector’s environmental impact. Under these guidelines, ports are expected to cut carbon emissions per tonne of cargo by 30 per cent by 2030, electrify a significant share of their equipment and source more than 60 per cent of their energy from renewable sources. These targets are designed to scale up further towards 2047, signalling that the green transition is a continuous process.
On the ground, ports are already adopting cleaner operational practices. Shore-to-ship power systems are enabling vessels to switch off diesel engines while docked, reducing air pollution in nearby urban areas. Electrified cranes, vehicles and cargo-handling equipment are lowering noise levels, cutting fuel costs and improving worker safety, delivering tangible benefits to local communities long affected by port-related pollution.
Water management and biodiversity protection are also gaining prominence. Ports, which consume large volumes of freshwater and generate wastewater and dredged material, are increasingly focusing on recycling wastewater, minimising discharge and reusing dredged material for construction or coastal protection. Efforts to restore mangroves and expand green cover are helping absorb carbon emissions and protect shorelines from storms and erosion, risks that are intensifying with climate change.
Together, these measures highlight how India’s ports are seeking to balance rapid growth with environmental responsibility, positioning green development as a cornerstone of the country’s maritime future.
