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

India's Climate Targets: Net Zero 2070 and 45% Intensity Reduction by 2030

India announced its net zero by 2070 target at COP26 in Glasgow in November 2021. This makes India one of over 130 countries with a net zero commitment, though India's 2070 horizon reflects both its late development stage and its position as a historically low per-capita emitter with a right to continued energy growth for its 1.4 billion people (Source: Climate Action Tracker, 2026).

India's near-term climate target is more specific and more immediately relevant to procurement and infrastructure decisions: a 45% reduction in the carbon intensity of GDP from 2005 levels by 2030, committed under India's updated Nationally Determined Contribution (NDC). India had already achieved a 36% reduction by 2020, meaning the remaining 9 percentage points of intensity reduction must be achieved in the decade to 2030. Energy efficiency in buildings, industry, and outdoor infrastructure, including street lighting, is a primary lever in this calculation (Source: cyberpeace.org, March 2025).

India's Long-Term Low Emission Development Strategy (LT-LEDS), submitted at COP27, identifies five structural levers for the net zero pathway: renewable energy scale-up, energy efficiency, green hydrogen, carbon removal, and the LiFE (Lifestyle for Environment) behavioural programme. Energy efficiency, which encompasses LED lighting, is the only lever that is simultaneously available today, cost-negative over its lifecycle, deployable without new grid infrastructure, and applicable from a 9W LED lamp to a 500-pole municipal street lighting system. The PAT scheme, UJALA programme, and BEE's Minimum Energy Performance Standards are all active components of this lever (Source: ScienceDirect, April 2025).

India's Grid Emission Factor: The Number Behind Every Carbon Calculation

The grid emission factor is the single most important number for any carbon calculation involving electricity consumption in India. It tells you how many kilograms of CO2 are emitted per kilowatt-hour of electricity consumed from the Indian grid. Every LED street light energy saving, every solar street light installation, and every corporate ESG report that claims electricity-related carbon reduction must use this number.

The authoritative source is the Central Electricity Authority (CEA), which publishes the CO2 Baseline Database for the Indian Power Sector annually. CEA Version 21.0, published December 2025, sets the provisional weighted average emission factor for FY 2024-25 at 0.710 tCO2/MWh, or 0.71 kg CO2 per kWh (Source: CEA Version 21.0, December 2025, as cited in reclimatize.in, April 2026). This is the factor to use for all Scope 2 emission calculations, CCTS compliance reporting, and SEBI BRSR sustainability disclosures for the current financial year.

This factor has been declining year on year as India adds renewable capacity: it was 0.774 a decade ago, fell to 0.727 in FY 2023-24, and is now 0.710 for FY 2024-25. The trend will continue as renewable penetration increases. This means that the carbon saving per kWh saved from LED lighting is declining over time as the grid gets cleaner, reinforcing the case for acting now: the carbon saving per LED conversion is highest today and will reduce as the grid decarbonises.

The Carbon Math: How Much CO2 Does One LED Street Light Save?

The carbon saving from replacing one street light with LED follows a straightforward formula: energy saved (kWh) multiplied by the grid emission factor (0.71 kg CO2/kWh). The energy saved depends on the legacy technology being replaced and the wattage of the LED replacement.

Replacing HPSV (High Pressure Sodium Vapour) with LED

A 250W HPSV street light with its magnetic ballast draws 290W. Replacing it with a 100W LED street light saves 190W per fitting. Running 12 hours per night, 365 nights per year:

Energy saved = 190W x 12 hrs x 365 days / 1000 = 832 kWh per year per fitting.

CO2 saved = 832 kWh x 0.71 kg CO2/kWh = 591 kg CO2 per year per fitting.

For a municipal road with 100 such fittings: 59.1 tonnes CO2 per year. Over 10 years: 591 tonnes CO2 avoided from a single 100-pole road project.

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.

National Impact: UJALA and SLNP Have Already Saved Millions of Tonnes

India's two flagship LED deployment programmes provide a striking demonstration of what happens when LED adoption reaches national scale.

UJALA scheme: LED bulbs for homes

The UJALA (Unnat Jyoti by Affordable LEDs for All) scheme, implemented by EESL, has distributed over 367 million LED bulbs at subsidised prices to Indian households. The result: annual energy savings of over 38.6 million tonnes of CO2 per year (Source: Drishti IAS, citing Ministry of Power data). This makes UJALA one of the largest demand-side energy efficiency programmes in the world by CO2 reduction impact. The LED bulbs replaced 40W to 60W incandescent and CFL bulbs with 5W to 12W LEDs across households in every Indian state.

SLNP: LED street lights for municipalities

The Street Light National Programme (SLNP), also implemented by EESL, has installed 1.34 crore LED street lights across India, replacing HPSV and metal halide street lights on municipal roads. The programme delivers annual energy savings of 9,001 million units (MU) of electricity per year and CO2 reduction of 6.2 million tonnes annually, with peak demand reduction of 1,500 MW (Source: Ministry of Power, January 2026). The financial model allows municipalities to replace lights with zero upfront capital: they pay EESL from the electricity cost savings over 7 years.

The EESL SLNP model is expanding through its smart phase, targeting 5G-integrated smart poles across 500+ Indian cities by 2030, with LED lighting as the base load component. Each city that participates in the next SLNP phase adds to the national CO2 reduction tally directly.

Solar Street Lights: The Complete Scope 2 Eliminator

An LED street light connected to the grid reduces CO2 emissions compared to HPSV or metal halide, but it still draws power from the grid and therefore still contributes some Scope 2 emissions (0.71 kg CO2 per kWh consumed). A solar street light eliminates Scope 2 emissions from that lighting point entirely. The energy source is sunlight; the only emissions are in the manufacturing of the panel, battery, and fixture (embodied carbon), not in operation.

For organisations required to report Scope 2 emissions under SEBI BRSR, the distinction matters significantly. A corporate campus with 100 grid-connected LED street lights at 50W each, running 12 hours per night, consumes 219,000 kWh per year and generates 155 tonnes of Scope 2 CO2 annually. Replacing those same 100 poles with solar street lights reduces that Scope 2 figure to zero. In a BRSR report, this appears as a 155-tonne reduction in Scope 2 greenhouse gas emissions, a measurable, auditable ESG achievement.

For corporate campus sustainability managers, ESG consultants, and township developers targeting net zero operations, solar street lights are the only outdoor lighting technology that delivers a zero Scope 2 emissions footprint from day one. Xera Tech's semi-integrated solar street lights (12W to 120W, LiFePO4 battery, BIS IS 16102 certified) are the correct specification for this application.

BEE PAT Scheme, CCTS and Carbon Credits from LED Lighting

BEE PAT scheme: energy savings for large industries

The Bureau of Energy Efficiency's Perform Achieve Trade (PAT) scheme covers energy-intensive industries in nine sectors (cement, steel, aluminium, fertilisers, paper, textiles, chlor-alkali, refineries, and petrochemicals) and sets mandatory energy consumption reduction targets. Designated Consumers (DCs) that reduce energy consumption below their targets earn Energy Saving Certificates (ESCerts) that can be traded. LED lighting upgrades in factory buildings, yards, and perimeters are among the fastest and most cost-effective ways for DCs to accumulate ESCerts because lighting energy savings are immediate, measurable, and require no process changes.

For a 1,000-worker factory replacing 100 units of 400W metal halide highbay and flood lights with 150W LED alternatives, the annual energy saving is 131,400 kWh (300W saved per fitting x 12 hrs x 365 days x 100 fittings / 1000). At 0.71 kg CO2/kWh, this generates a verifiable 93.3 tonnes of CO2 reduction per year, which contributes to the factory's PAT target compliance and potentially generates tradable ESCerts.

India's Carbon Credit Trading Scheme (CCTS)

India's Carbon Credit Trading Scheme was notified under the Energy Conservation (Amendment) Act 2022 and became operational for its first compliance cycle in 2025-26. The CCTS integrates the existing PAT scheme into a broader carbon market framework and will eventually extend to non-PAT sectors. Under CCTS, the grid emission factor from CEA (currently 0.710 kg CO2/kWh) is the prescribed multiplier for calculating the Scope 2 emission reduction from electricity efficiency projects.

LED street lighting projects in municipalities, townships, and industrial estates that generate measurable, verifiable electricity savings and the corresponding CO2 reductions may be eligible to register as carbon credit projects under CCTS's voluntary offset mechanism (the exact rules for this category are under finalisation for the 2026-27 cycle). The Carbon Credit Trading Scheme is expected to attract increasing investor interest in verified energy efficiency projects as the market matures through 2027 and 2028, making LED street light conversions potentially financeable through carbon credit revenues in addition to electricity cost savings.

SEBI BRSR and ESG Reporting: Why LED Lighting Is Now a Compliance Requirement

The Securities and Exchange Board of India (SEBI) introduced the Business Responsibility and Sustainability Reporting (BRSR) framework as a mandatory disclosure requirement for the top 1,000 listed companies by market capitalisation from FY 2022-23 onwards. BRSR requires companies to disclose, among other things, total energy consumption, renewable energy consumption, Scope 1 (direct) and Scope 2 (indirect from purchased electricity) GHG emissions, and actions taken to reduce energy consumption.

What BRSR means for outdoor lighting

Every unit of electricity consumed by a company's grid-connected facilities, including outdoor LED street lights and flood lights on corporate campuses, factory yards, and warehouses, appears as a Scope 2 emission in the BRSR report. At India's grid emission factor of 0.71 kg CO2/kWh, a corporate campus with 200 grid-connected 100W LED street lights running 12 hours per night generates 0.71 x (200 x 100 x 12 x 365 / 1000) = 62.1 tonnes of Scope 2 CO2 per year from outdoor street lighting alone.

Under BRSR, this figure is disclosed publicly. Investors, ESG rating agencies (MSCI ESG, Sustainalytics, CDP), and institutional lenders increasingly evaluate this number. Replacing these 200 grid-connected LED street lights with solar street lights reduces the disclosed Scope 2 figure by 62.1 tonnes per year, a measurable, auditable improvement. For a company with a net zero or Scope 2 reduction commitment, this is a reportable achievement in every subsequent BRSR cycle.
