Suzlon Group, one of India’s largest wind energy solutions provider, announced that its Made-in-India wind turbine model S144 has achieved the lowest product carbon footprint (PCF) of just 6.17 gCO₂ per kilowatt-hour of electricity generated. This certification measures the entire lifecycle impact—covering “cradle-to-grave” emissions.
Independent Global Validation
The milestone was independently verified by Indian Register Quality Systems (IRQS), a reputed certification and testing body with over 30 years of expertise. The assessment adhered to globally recognised standards, including:
*ISO/IEC 17029:2019 (Validation and verification principles)
*ISO 14067:2018 (Carbon footprint requirements)
*ISO 14021:2016 + Amd 1:2021 (Environmental claims and labelling)
Additionally, TÜV SÜD Poland, a 150-year-old global certification organisation, validated the S144 turbine as a low-carbon footprint wind solution under ISO 14067 and ISO 14021 standards.
Sustainability Through Design and Sourcing
Suzlon attributes this achievement to integrated sustainability measures across design, manufacturing, and sourcing. Key initiatives include:
*Reducing steel usage by 2.5 times through advanced engineering
*Using recycled steel and scrap extensively
*Sourcing 83.25% of components locally from Tier-1 Indian suppliers, minimising logistics emissions
As reported by thehindubusinessline.com, further, the company adopted green steel, with emissions below 2.2 tCO₂e per ton of production, and powered its manufacturing processes with renewable energy.
Extended Lifespan and Circularity Goals
By optimising the lifecycle, Suzlon has extended the S144’s lifespan to 25 years, enhancing long-term performance and sustainability. JP Chalasani, Chief Executive Officer, Suzlon Group, stated, “The S144’s independently verified lowest carbon footprint reflects our commitment to responsible design, sourcing, and manufacturing. With this achievement, we prove that world-class clean energy can be designed and built sustainably in India. Our next step is to move from lowest-carbon manufacturing to true circularity, setting new benchmarks for the renewable energy industry.”
