How LED Lighting Reduces Carbon Emissions: India's Energy Efficiency and Net Zero 2070 Goals

Every LED street light that replaces a sodium vapour lamp in India avoids approximately 124 kg of CO2 per year at the current grid emission factor of 0.71 kg CO2/kWh (CEA Version 21.0, December 2025). Every solar street light avoids it entirely, eliminating Scope 2 emissions at that pole permanently. With India committed to net zero by 2070 and a 45% carbon intensity reduction by 2030, with SEBI now mandating Scope 2 disclosure in BRSR reports, and with India's Carbon Credit Trading Scheme operational from 2025-26, LED and solar lighting upgrades have shifted from an energy-saving decision to a carbon compliance decision for every municipality, corporate campus, township developer, and industrial estate in India.

Replacing metal halide with LED

A 400W metal halide fitting (450W with ballast) replaced with a 150W LED saves 300W per fitting. Energy saved per year = 300W x 12 x 365 / 1000 = 1,314 kWh. CO2 saved = 1,314 x 0.71 = 933 kg CO2 per year per fitting. For a 50-fitting stadium or factory yard perimeter: 46.7 tonnes CO2 per year.

Legacy Fitting Legacy Draw (with ballast) LED Replacement Power Saved Annual Energy Saved (kWh) Annual CO2 Saved (kg)
