SECR Reporting for Automotive Companies

Automotive manufacturing is energy-intensive, particularly paint shops with their drying ovens. The sector is transitioning to EV production with changing energy profiles.

SECR Requirements for Automotive

Automotive 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 automotive 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 Automotive

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

  • Natural gas for paint ovens
  • Combustion in engine testing
  • Refrigerants for HVAC
  • Fleet fuel
  • Emergency generators

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 Automotive

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 production lines
  • Robotics and automation
  • Paint shop operations
  • Compressed air systems
  • Office energy

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

Intensity Ratios for Automotive

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 automotive companies, common intensity ratios include:

kgCO2e per vehicle produced
kgCO2e per £m revenue
tonnesCO2e per employee
kgCO2e per m² of plant

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 automotive include:

01

Heat recovery from paint ovens

02

Variable speed compressed air

03

LED lighting in plants

04

Efficient robotics

05

Building envelope improvements

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 Automotive SECR Challenges

  • Paint shop is 50-70% of energy use
  • Just-in-sequence production
  • Supplier integration
  • EV transition impacts

These challenges are common across the automotive 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

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

ESOS
EU ETS (for some suppliers)

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