India has announced significant reductions in Goods and Services Tax (GST) rates across renewable energy technologies, waste management services, biodegradable products, and green transportation as part of a comprehensive strategy to accelerate the country's transition to sustainable energy and support its Net Zero 2070 commitment.

Renewable Energy Tax Reforms

The government has reduced GST rates from 12% to 5% on a wide range of solar and wind energy devices. This reduction covers solar cookers, bio-gas plants, solar power-based devices, solar power generators, wind mills, Wind Operated Electricity Generators (WOEG), waste-to-energy plants and devices, solar lanterns, solar lamps, ocean waves and tidal waves energy devices and plants, and photovoltaic cells, whether or not assembled in modules or made up into panels.

The Ministry of New and Renewable Energy is currently operating a Production Linked Incentive Scheme for High Efficiency Solar PV Modules with an outlay of INR 24,000 crore. This scheme aims to build large-scale factories in India to produce high-efficiency solar panels, which will increase clean energy production, reduce dependence on imports, and help meet India's renewable energy goals.

India's solar energy capacity has demonstrated remarkable growth, increasing more than 42 times from 2.82 GW in 2014 to 119.54 GW as of July 31, 2025. The GST reduction is expected to directly decrease capital costs of solar panels, PV cells, wind turbines, and related devices, enhancing the viability of solar and wind projects and leading to lower tariffs for end consumers.

Waste Management and Pollution Control Initiatives

GST on services provided by Common Effluent Treatment Plants (CETPs) has been reduced from 12% to 5%. As of August 4, 2025, there are 222 Common Effluent Treatment Plants operating across India, with 53 CETPs designed to achieve Zero Liquid Discharge (ZLD) located in various states. The tax reduction on CETPs is intended to motivate industries to use centralized waste treatment methods, resulting in a pollution-free environment and supporting sustainable development in industrial areas.

This measure will assist municipal corporations in implementing clean energy solutions for managing waste and creating green jobs in areas like waste segregation, plant operations, and maintenance.

Biodegradable Materials and Plastic Alternatives

The government has implemented a substantial GST reduction on biodegradable bags, cutting rates from 18% to 5%. This reduction makes biodegradable bags more affordable, encouraging consumers and retailers to move away from single-use plastics and helping to decrease plastic pollution. The measure supports India's adherence to the Plastic Waste Management Rules, 2022, and reinforces the ban on single-use plastics.

It is expected to promote investment in research and development and the expansion of bio-polymers, starch-based, and compostable materials. The quicker adoption of biodegradable bags is anticipated to lower plastic leakage into rivers, soil, and marine environments.

Green Transportation and Mobility Solutions

GST rates on buses with a seating capacity of 10 or more persons have been reduced from 28% to 18%. This lower tax rate will reduce the upfront cost of buses and minibuses, spurring demand from fleet operators, corporates, schools, tour operators, and state transport undertakings. The reduction encourages the shift from private vehicles to shared and public transport, reducing congestion and pollution while promoting fleet expansion and modernization.

Commercial goods vehicles, including trucks and delivery vans, have also received GST reductions from 28% to 18%. Trucks carry 65% to 70% of goods traffic in India, serving as the backbone of the country's supply chain. The GST rate cuts will encourage fleet expansion and modernization, phasing out older vehicles and leading to lower pollution and emissions.

Climate Goals and Environmental Impact

These reforms align with national initiatives, including Viksit Bharat 2047 and the LiFE movement, which support India's Net Zero 2070 ambition and strengthen adherence to the Paris Agreement by making green alternatives more affordable and accessible to consumers and industries. India announced its target to achieve Net Zero by 2070 at the 26th Conference of Parties to the UNFCCC in November 2021.

India's strategy rests on four pillars: minimal historical emissions, rising energy needs, pursuit of low-carbon development, and building climate resilience. The country has progressively continued decoupling economic growth from greenhouse gas emissions, with the emission intensity of India's gross domestic product reducing by 36% between 2005 and 2020.

The GST cuts are expected to bolster domestic manufacturing by supporting India's solar cell and module manufacturing ecosystem under PLI schemes, making domestic products more competitive against imports. This will make solar pumps more affordable, reducing irrigation costs and providing support to farmers while creating employment opportunities in the green technology sector.
