What is a Carbon Audit?

A Carbon Audit, sometimes referred to as a carbon emissions audit or organisational carbon footprint assessment, measures the greenhouse gas emissions associated with your business activities.

It establishes your carbon footprint in tonnes of carbon dioxide equivalent (tCO₂e) and identifies where those emissions originate across Scope 1, Scope 2 and relevant Scope 3 sources.

This gives your organisation a reliable emissions baseline that can be used for carbon reduction planning, Net Zero targets, customer and tender requirements, and ongoing carbon reporting.

Our audits are completed in line with internationally recognised standards such as the Greenhouse Gas Protocol and ISO 14064, ensuring accuracy and credibility.

The measurement of greenhouse gas emissions are categorised into three scopes, defined by the GHG Protocol

Scope 1: The direct emissions you control

Scope 2: The indirect emissions from the energy you purchase

Scope 3: The broader emissions from your supply chain, travel, and waste

Why Does Your Business Need a Carbon Audit?

Whether you’re responding to client demands, bidding on new work & tenders, preparing for legislation, or simply looking to reduce costs and environmental impact, a carbon audit can help achieve any or all of these:

  • A baseline measurement to help understand your carbon footprint and for setting carbon reduction targets.
  • Credibility with clients and the market as well as with investors and stakeholders.
  • Compliance with upcoming UK and international sustainability reporting requirements.
  • Operational insights into your business that can lead to efficiency savings and reduced costs.
  • A competitive advantage in tenders and supply chain partnerships.

What Happens After a Carbon Audit?

A Carbon Audit is the starting point for understanding your emissions. From here, businesses can develop a structured Carbon Reduction Plan, implement a Net Zero strategy and use accurate data for ongoing carbon reporting and compliance.

Our Business Carbon Audit Process

Scoping & Planning

We define your reporting boundaries, select the right measurement methodology, and identify the emissions sources to be included.

Data Collection

Using our Carbon Data Request Checklist, we gather information from utility bills, travel records, waste reports, company cars & fleet logs, and other relevant sources.

Calculation & Analysis

Our team uses recognised conversion factors and standards to calculate your CO₂e emissions for each section of the three scopes.

Reporting & Recommendations

We present a clear, visual Carbon Audit Report that includes your total footprint, key emissions hotspots, and recommendations and actionable steps for reduction.

What Does a Carbon Audit Report Include?

At the end of your Carbon Audit, you will receive a clear assessment of your organisation’s greenhouse gas emissions and the information needed to understand where those emissions are generated.

Depending on the agreed scope of the audit, your Carbon Audit Report may include:

• Your total organisational carbon footprint in tCO2e
• Scope 1 emissions
• Scope 2 emissions
• Relevant Scope 3 emissions
• Organisational and operational boundaries
• Data sources and calculation methodology
• Key emissions hotspots
• Breakdown of emissions by activity or source
• Data gaps and assumptions
• Opportunities for carbon reduction
• Recommended next steps

The report can then provide the evidence base for your Carbon Reduction Plan, Net Zero strategy, sustainability reporting and future emissions comparisons.

Carbon Audits for Tenders & Procurement

Businesses are increasingly being asked to provide carbon emissions information by customers, procurement teams and supply chain partners.

A Carbon Audit establishes a credible emissions baseline that can support Carbon Reduction Plans, tender submissions, supplier questionnaires and customer sustainability requirements.

If you have been asked to provide your organisation’s carbon footprint or emissions data, we can help you understand what needs to be measured, which information you need to collect and how the results should be presented.

Frequently Asked Carbon Audit Questions

A carbon audit helps your business understand where its greenhouse gas emissions come from and provides a measurable baseline for reducing them.

Businesses may carry out a carbon audit to support carbon reduction and Net Zero targets, respond to customer or supply chain requirements, prepare for sustainability reporting, support tender and procurement requirements, or identify opportunities to reduce energy use and operating costs.

It gives you the evidence needed to make informed carbon reduction decisions rather than relying on estimates or assumptions.

A carbon footprint is the calculated total of the greenhouse gas emissions associated with your business, usually expressed as tonnes of carbon dioxide equivalent (tCO2e).

A carbon audit is the process used to identify, collect and assess the emissions data that contributes to that carbon footprint. It can also help identify where emissions occur and where opportunities exist to reduce them.

Put simply, the carbon audit is the assessment process, while the carbon footprint is one of the key results produced by that process.

Scope 1 emissions are direct greenhouse gas emissions from sources your business owns or controls, such as fuel used in company vehicles, boilers or other onsite equipment.

Scope 2 emissions are indirect emissions associated with the energy your business purchases, such as electricity and certain forms of purchased heating or cooling.

Scope 3 emissions are other indirect emissions across your value chain. These can include purchased goods and services, business travel, employee commuting, waste, transportation and distribution, and other upstream and downstream activities.

Understanding all three scopes gives your business a more complete picture of its carbon footprint.

The information required depends on the size and complexity of your organisation and the emissions being measured. Typically, we may need information including:

  • • Business locations, organisational structure and reporting boundaries
  • • Electricity, gas and other fuel consumption
  • • Company vehicle and fleet mileage or fuel use
  • • Business travel, including flights, rail, taxis and hire cars
  • • Employee commuting information
  • • Waste volumes and disposal methods
  • • Water consumption
  • • Purchased goods and services where relevant
  • • Transportation and distribution data
  • • Other information required to calculate relevant Scope 3 emissions
  • We can help identify what information is required and where reasonable estimates or recognised calculation methods can be used if complete data is not immediately available.

Most businesses should review and update their carbon footprint at least annually. Regular carbon audits allow you to compare emissions against your baseline, measure the impact of reduction initiatives and maintain current information for customers, tenders and sustainability reporting. The appropriate frequency can vary depending on your reporting requirements, business changes and carbon reduction objectives.

The time required for a carbon audit depends on the size and complexity of your organisation, the number of sites involved, the emissions being measured and how readily available your data is.

A relatively straightforward business carbon audit can often be completed within a few weeks, while larger organisations or audits involving extensive Scope 3 data may take longer.

Having energy, fuel, travel, waste and other relevant records available at the start of the process can significantly reduce the time required.

It can. A carbon audit can identify areas where your business is using more energy, fuel or resources than necessary, helping uncover opportunities to reduce both emissions and operating costs.

Potential savings might come from improving energy efficiency, reducing unnecessary travel or fuel consumption, changing operational processes, reducing waste or reviewing purchasing decisions.

Not every carbon reduction measure will produce an immediate financial saving, but a carbon audit gives you the evidence needed to prioritise the actions that can deliver the greatest environmental and commercial benefit.

Yes. Carbon and sustainability information is increasingly requested during public sector and private sector procurement, particularly where buyers assess suppliers’ environmental performance or require evidence of carbon measurement and reduction.

A carbon audit can establish a credible emissions baseline and provide the data needed to support Carbon Reduction Plans, sustainability reporting and other carbon-related tender requirements.

The exact requirements vary between procurement exercises, so businesses should always check the specific tender criteria before submitting their response.
