SECR Requirements for Telecommunications

Telecom companies meeting 2 of 3 qualifying criteria. Streamlined Energy and Carbon Reporting (SECR) requires qualifying companies to disclose their UK energy use, greenhouse gas emissions, and energy efficiency measures in their annual accounts.

Understanding your specific obligations as a telecommunications business is crucial for compliance. This guide covers the emission sources, intensity ratios, and efficiency measures most relevant to your sector.

Quick Check: Use our free compliance checker to see if your company meets the SECR thresholds based on your employee count, turnover, and balance sheet.

Scope 1 Emissions in Telecommunications

Scope 1 emissions are direct emissions from sources your company owns or controls. For telecommunications companies, these typically include:

  • Diesel for backup generators at cell towers
  • Natural gas for offices
  • Fleet fuel for engineers
  • Refrigerants for cooling

These emissions are calculated by multiplying your fuel consumption by the UK Government conversion factors. You'll need to collect data from utility bills, fuel cards, and maintenance records.

Scope 2 Emissions in Telecommunications

Scope 2 emissions come from purchased electricity, heat, steam, and cooling. SECR requires you to use the location-based method (UK grid average), though you may also disclose market-based figures if you purchase green energy.

  • Electricity for mobile network infrastructure
  • Data centres and exchanges
  • Cooling systems
  • Office energy

Collect electricity consumption data from your bills or smart meters. For most telecommunications operations, electricity represents a significant portion of total emissions.

Intensity Ratios for Telecommunications

SECR requires at least one intensity ratio—a metric that normalises your emissions against business activity. This helps stakeholders understand whether emission changes reflect business growth or efficiency improvements.

For telecommunications companies, common intensity ratios include:

kgCO2e per subscriber
kgCO2e per £m revenue
kgCO2e per employee
kgCO2e per petabyte of data

Choose a ratio that best reflects your business model. For example, if you're a high-volume, low-margin operation, "per tonne of product" might be more meaningful than "per £m revenue."

Energy Efficiency Actions

SECR requires a narrative describing energy efficiency measures taken during the reporting period. Simply stating "no measures taken" is non-compliant if opportunities existed.

Typical efficiency measures for telecommunications include:

01

Free cooling for data centres

02

AI-powered network optimisation

03

Energy-efficient 5G equipment

04

Virtualisation to reduce hardware

05

Renewable energy procurement

Tip: Quantify your savings where possible. "Installed LED lighting, reducing consumption by 50,000 kWh and saving £7,000 annually" is stronger than "upgraded to LED lighting."

Common Telecommunications SECR Challenges

  • 24/7 network operation requirements
  • Legacy infrastructure efficiency
  • Rapid technology change
  • Distributed cell tower portfolio

These challenges are common across the telecommunications sector. Addressing them early in your reporting process will save time and improve accuracy. Consider engaging specialists if your operations are particularly complex.

Other Regulations to Consider

Telecommunications companies may also need to comply with additional energy and carbon regulations:

ESOS

Understanding how these frameworks interact helps streamline compliance and avoid duplication of effort.
