India's Harit Sagar guidelines target 30% port carbon cut by 2030

India outlined a green maritime agenda anchored by the Indian Ports Act, 2025 and Harit Sagar Green Port Guidelines, targeting a 30% reduction in carbon emissions per ton of cargo by 2030. Compliance will become a prerequisite for participation in India's maritime trade, making ESG reporting an operational necessity for the sector.

India outlined a sweeping agenda to integrate sustainability into maritime operations, managing pressures from cargo volumes that reached 855 million tonnes in FY 2024-25 while meeting its Intended Nationally Determined Contributions. The plan is driven by Maritime India Vision 2030 and reinforced by the newly enacted Indian Ports Act, 2025, which replaces the colonial-era 1908 Act and institutionalizes greener operations. The Harit Sagar Green Port Guidelines, launched in 2023, set quantifiable targets including a 30% cut in carbon emissions per ton of cargo by 2030.

The roadmap affects port operators, vessel operators, shipbuilders, logistics providers and finance institutions across India's maritime ecosystem. Guidelines mandate renewable energy share exceeding 60% by 2030 and 90% by 2047, phased shore-to-ship power for all EXIM vessels by 2025, electrifying over 50% of material-handling equipment by 2030, and expanded LNG bunkering. New Mangalore Port has achieved 100% solar power integration, while Kandla, Paradip and Tuticorin are identified for development as Green Hydrogen hubs supporting the National Green Hydrogen Mission.

Maritime businesses should prepare for Harit Sagar compliance becoming a prerequisite for participation in India's maritime trade, transforming ESG reporting from voluntary to a core operational necessity. Operators should monitor the 2030 and 2047 emission and renewable-energy targets, the shore-to-ship power mandate, and equipment electrification deadlines. The roadmap accelerates demand for green vessels, low-emission technologies and sustainable port infrastructure, while unlocking access to dedicated green finance instruments aligned with IMO targets.
