STL (NSE: STLTECH), a global provider of connectivity solutions for AI-ready digital infrastructure, has announced major steps towards reducing its carbon emissions by shifting key manufacturing operations in India to renewable energy and adopting green hydrogen in its glass manufacturing process.
STL has moved the electricity supply for all four of its manufacturing plants in Chhatrapati Sambhaji Nagar (Aurangabad), Maharashtra, to 100% green power generated from wind and solar sources. The transition has been enabled through the Maharashtra State Electricity Distribution Company Limited (MSEDCL).
The company expects the move to reduce market-based Scope 2 emissions from its optical fibre and optical fibre cable manufacturing plants by around 65%. The shift forms part of STL’s wider strategy to reduce emissions from its operations and progress towards its Net Zero targets.
STL has also introduced 100% green hydrogen into its glass manufacturing operations. Glass manufacturing is one of the energy-intensive stages in optical fibre production and has traditionally depended on conventionally produced hydrogen and oxygen. The use of green hydrogen is expected to reduce emissions from this difficult-to-abate part of the production process.
The company’s sustainability programme also covers its products. STL has developed a portfolio of Eco-labelled Certified Optical Products, supported by Life Cycle Assessment to measure their environmental impact. One example is STL’s G.657.A2 optical fibre, which is widely used in data centre and telecommunications networks. The carbon footprint of the fibre has been reduced from 4.7 kg CO₂e per fibre kilometre to 0.9 kg CO₂e per fibre kilometre, representing an approximately 80% reduction.
STL has also updated its corporate mobility policy to encourage employees to adopt lower-emission vehicles. Under its company car policy, employees choosing electric and hybrid vehicles will receive dedicated incentives and higher eligibility limits. The move is aimed at reducing the company’s Scope 3 operational emissions.
Rahul Puri, CEO, ONB, STL, said the company’s decarbonisation efforts cover its manufacturing operations, products and employee mobility. “Decarbonization at STL is a set of connected decisions, from the power that runs our plants to the materials that go into every kilometre of fibre we make, to the policies we make for our employees. By combining renewable energy, Green Hydrogen and Eco-labelled-led product innovation, we are making measurable progress towards building a greener and environmentally-friendly manufacturing ecosystem,” Mr Puri said.
STL provides connectivity solutions for AI-ready infrastructure, FTTx, rural, enterprise and data centre networks. The company operates manufacturing facilities across North America, Europe and Asia and serves customers in more than 100 countries. Its customers include data centre and cloud companies, telecom operators, internet service providers and large enterprises. STL’s business strategy is focused on customer needs, research and development and sustainability.
