Suzlon Group's Made in India wind turbine model, S144, has recorded the lowest Product Carbon Footprint (PCF) of just 6.17 gCO₂ per kilowatt-hour (kWh) of electricity generated in the Cradle to Grave boundary. It has been verified by Indian Register Quality Systems (IRQS) in line with international standards, including ISO/IEC 17029:2019 for validation and verification principles, ISO 14067:2018 for product carbon footprint requirements and ISO 14021:2016 + Amd 1:2021 for environmental labels and self-declared environmental claims.
The S144’s lowest carbon footprint is the result of several integrated sustainability measures undertaken across its design, optimisation of resources for manufacturing, local sourcing, use of green steel and renewable energy. The company has redesigned the turbine to cut steel use by ~2.5 times, incorporating recycled steel and scrap, while sourcing 83.25 percent of components locally from tier-I Indian suppliers. The use of low-carbon steel (<2.2 t CO₂e/t of production) and renewable energy in manufacturing has further reduced emissions drastically. Additionally, Suzlon has been able to enhance the product lifecycle to 25 years, delivering long-term performance and advancing India’s clean energy goals.
Speaking in this regard, JP Chalasani, Chief Executive Officer, Suzlon Group, said, “True sustainability leadership means embedding sustainability into organisational process, product level and across the value chain—not treating it as an add-on. At Suzlon, this has been our philosophy for over 30 years. The S144’s independently verified lowest carbon footprint reflects this commitment, showing how responsible design, sourcing and manufacturing can deliver real impact. With the S144, we prove that world-class clean energy can be designed and built sustainably in India. Our next step is to move from the lowest-carbon manufacturing to true circularity, setting new benchmarks for the renewable energy industry.”
