STL (NSE: STLTECH) said it advanced its decarbonisation and Net-Zero ambitions by moving all four manufacturing plants in Chhatrapati Sambhaji Nagar (Aurangabad), Maharashtra, to 100% Green Power generated from wind and solar through Maharashtra State Electricity Distribution Company Limited (MSEDCL). The transition is expected to reduce market-based Scope 2 emissions by about 65% across its optical fibre and optical fibre cable plants. STL also began using 100% Green Hydrogen in glass manufacturing, an energy-intensive stage of optical fibre production, and offers a range of Eco-labelled Certified Optical Products supported by life cycle assessment. Its G.657.A2 optical fibre, used extensively in data centre and telecom networks, now has a carbon footprint of 0.9 kilograms of CO2e per fibre kilometre, down 80% from 4.7 kilograms. The company also updated its corporate mobility policy with dedicated incentives and higher limits for employees choosing electric and hybrid vehicles, aiming to reduce its Scope 3 operational carbon footprint and advance its broader ESG goals.
