Carbon Accounting for the Telecom Sector in India

India's telecom sector has become a critical focus for carbon accounting and ESG compliance. With Jio, Airtel, Vodafone Idea, and BSNL all ranking within SEBI's top 1000 listed companies, these organizations must now meet stringent carbon disclosure requirements under BRSR (Business Responsibility and Sustainability Reporting). The sector's carbon footprint is substantial - and growing - making accurate emission accounting essential for regulatory compliance and stakeholder trust.

Understanding Indian Telecom Emissions Context

Major Players and Regulatory Scope

India's telecom giants operate under intense regulatory scrutiny. Jio (Reliance), Airtel, Vodafone Idea, and BSNL collectively serve over 1 billion subscribers across the country. Because these companies rank in SEBI's top 1000 listed entities, they must comply with BRSR requirements, which mandate comprehensive carbon disclosure starting from financial year 2022-23 onwards.

The scale of India's telecom infrastructure is staggering. With over 700,000 active telecom towers dotting the landscape, the sector consumes enormous quantities of electricity and fuel. Understanding the emissions from this infrastructure is fundamental to carbon accounting in the telecom space.

Why Telecom Towers Are Emission Hotspots

Telecom towers are among the most electricity-intensive assets in India's telecommunications network. Each tower requires 24/7 power supply to maintain network availability and service quality. In a country where grid electricity carries a carbon intensity of approximately 0.820 kg CO2e per kilowatt-hour, the cumulative emissions from 700,000+ towers represent a significant portion of the sector's total carbon footprint.

The challenge is compounded by India's unreliable power supply in many regions. Backup power generation through diesel generators has traditionally been a standard practice at telecom towers, creating a dual emission problem.

Key Emission Sources in Indian Telecom

Scope 2 Emissions: Tower Electricity Consumption

Scope 2 emissions from electricity consumption dominate Indian telecom companies' carbon footprints. With India's grid carbon intensity at 0.820 kg CO2e/kWh, every kilowatt-hour drawn from the grid translates directly into carbon liability. Across 700,000+ towers, this multiplies rapidly.

Energy consumption at towers includes:

• Power systems and air conditioning
• Network equipment (base transceiver stations, routers, switches)
• Lighting and security systems
• Cooling infrastructure for sensitive equipment

Calculating Scope 2 emissions requires precise electricity consumption data from each tower - a challenge that many Indian telecom operators are only now beginning to address systematically.

Scope 1 Emissions: Diesel Generator Operations

Diesel generators remain a major Scope 1 emission source across Indian telecom towers. Backup power systems ensure continuous network availability during grid failures, which are common in many regions. However, diesel consumption at towers generates substantial CO2 emissions, often exceeding Scope 2 contributions in certain geographies.

The diesel dependency problem includes:

• Peak load shifting to generator operation during grid demand hours
• Weather-related power outages requiring extended generator runtime
• Aging tower infrastructure with inefficient generator sets
• Lack of standardized fuel consumption tracking across tower networks

Data Centre Electricity and Network Operations

Modern telecom networks depend heavily on data centres for call processing, billing, and content delivery. These facilities consume vast amounts of electricity and represent a growing Scope 2 emission source. Additionally, network equipment supply chains and e-waste management create significant Scope 3 emissions that Indian telecom companies are increasingly required to disclose.

BRSR Requirements for Indian Telecom Companies

Energy Intensity and Subscriber Metrics

BRSR requires Indian telecom companies to disclose energy intensity metrics, typically measured as energy consumption per subscriber. This standardized metric allows investors and regulators to compare emissions performance across operators.

Key BRSR disclosures include:

• Total energy consumption (MJ or kWh) per subscriber
• Percentage of renewable energy in total consumption
• Tower fuel consumption (diesel, renewable alternatives)
• Data centre energy efficiency metrics

Understanding What is BRSR Reporting? is essential for compliance officers tasked with gathering and validating these metrics.

Tower Fuel Consumption Disclosure

BRSR specifically mandates disclosure of fuel consumption at telecom towers. This requirement recognizes the sector's unique operational structure and the outsized emissions impact of backup power systems. Companies must report both:

• Total diesel consumption (in liters or units of energy)
• Percentage of towers using renewable backup power

Accurate tower-level tracking systems have become critical compliance infrastructure for Indian telecom operators.

Tower Greening Initiatives

Solar-Powered Tower Deployment

Indian telecom companies are increasingly deploying solar panels at remote towers to reduce diesel dependency. Solar-powered towers significantly lower both Scope 1 and Scope 2 emissions, particularly in high-sunlight regions. However, solar adoption faces challenges including:

• High upfront capital costs
• Land availability constraints
• Maintenance requirements in dusty environments
• Weather-dependent power generation reliability

Airtel and Jio have both announced ambitious solar tower targets, with thousands of solar installations already operational across their networks.

Battery Storage and Lithium-Ion Replacement

Advanced battery systems, particularly lithium-ion solutions, are replacing traditional diesel generators at tower sites. These systems store solar energy or grid electricity for use during outages, eliminating diesel generator runtime.

TRAI (Telecom Regulatory Authority of India) sustainability guidelines increasingly encourage battery-backed tower architectures. The benefits include:

• Reduced Scope 1 emissions from eliminated diesel use
• Improved power reliability
• Lower long-term operational costs
• Alignment with India's renewable energy targets

Understanding Scope 1 2 3 Emissions for Indian Businesses helps operators categorize these initiatives for accurate reporting.

Network Equipment Supply Chain and E-Waste

Scope 3 Emissions Growing in Importance

BRSR is increasingly scrutinizing Scope 3 emissions from telecom supply chains. Network equipment manufacturing, transportation, and end-of-life e-waste management create substantial upstream and downstream emissions.

Indian telecom companies must now track:

• Equipment supplier emissions (embodied carbon)
• Transportation emissions for hardware imports
• E-waste management and recycling processes
• Refurbished equipment reuse programs

This Scope 3 focus reflects global recognition that telecom equipment supply chains can rival operational emissions in magnitude.

Telecom Carbon Accounting in Practice

Implementing carbon accounting across a network of 700,000+ towers requires sophisticated systems and processes. Many Indian telecom operators are now deploying:

• Tower-level IoT sensors for real-time energy monitoring
• Cloud-based carbon accounting platforms
• Automated emissions reporting dashboards
• Third-party audit and verification processes

Greenio and similar platforms are helping Indian telecom operators consolidate tower-level data, calculate emissions accurately, and generate BRSR-compliant disclosures at scale.
