A carbon footprint is the total amount of greenhouse gas emissions caused directly and indirectly by an individual, organisation, event, or product, measured in carbon dioxide equivalents (CO2e). Understanding your carbon footprint matters because it provides the foundation for meaningful climate action, helps you meet growing regulatory requirements like CSRD, and addresses stakeholder expectations.
What exactly is a carbon footprint and why does it matter?
A carbon footprint represents the total greenhouse gas emissions generated by your activities, whether you’re an individual, business, event organiser, or product manufacturer. Think of it as your climate impact translated into a single number, measured in CO2 equivalents because carbon dioxide is the most common greenhouse gas we emit.
The concept goes beyond just carbon dioxide itself. Your footprint includes methane from waste, nitrous oxide from agriculture, and several other greenhouse gases, all converted into CO2 equivalents so we can compare apples to apples.
Why should you care about measuring your carbon footprint?
- Regulatory compliance is becoming unavoidable – Regulations like CSRD now require many European companies to measure and report their emissions, with penalties for non-compliance and expanding coverage each year
- Stakeholder pressure is intensifying – Your clients, investors, and partners expect credible, transparent answers backed by data, often making it a prerequisite for contracts and investment decisions
- You can’t reduce what you don’t measure – Without establishing a baseline, you have no way to track progress or set meaningful targets that demonstrate genuine improvement over time
- It reveals your biggest opportunities – Measurement shows where to focus resources for maximum impact, often identifying cost-saving opportunities alongside emissions reductions
Understanding your carbon footprint provides the foundation for everything that follows in your sustainability journey, from setting science-based targets to implementing reduction strategies that actually move the needle. Whether driven by compliance obligations, stakeholder demands, or genuine commitment to climate action, accurate measurement transforms sustainability from aspiration into actionable strategy, enabling you to make informed decisions about where to invest resources and how to communicate progress credibly.
How is a carbon footprint actually measured?
Carbon footprint measurement follows a structured methodology built around three emission scopes defined by the GHG Protocol:
- Scope 1: Direct emissions from sources you own or control – This includes fuel burned in company vehicles, emissions from manufacturing processes, or natural gas used in office heating, representing your most visible and controllable emissions
- Scope 2: Indirect emissions from purchased energy – These cover emissions from the electricity, heat, or cooling you purchase, with calculations varying based on whether you use location-based or market-based accounting methods
- Scope 3: All other indirect emissions in your value chain – This typically represents the largest portion and includes purchased goods and services, business travel, employee commuting, transportation and distribution, waste disposal, and the use of your products by customers
Each scope presents distinct measurement challenges and requires different data collection approaches. Scope 1 is the most straightforward to measure because you have direct control and visibility over your own operations. Scope 2 requires coordination with energy suppliers to obtain accurate consumption data and understanding of emission factors for your electricity grid. Scope 3 is where things get complicated, often requiring data collection from suppliers or estimation based on spend when specific data isn’t available, yet it frequently accounts for 70-90% of total emissions. Together, these three scopes create a comprehensive picture of your climate impact across the entire value chain, ensuring no significant emissions sources remain hidden from view.
What tools and approaches can you use to calculate your carbon footprint?
Your options for carbon footprint calculation range from basic online calculators to comprehensive carbon accounting software and specialised consultants. The right approach depends on your company size, complexity, and goals:
- Basic carbon calculators for quick estimates – These provide rough footprint assessments based on limited inputs like energy bills and travel data, useful for initial awareness but insufficient for regulatory reporting or strategic decision-making
- Carbon accounting software for systematic tracking – These platforms offer automated data collection, emission factor databases, and reporting aligned with frameworks like CDP, enabling consistent year-on-year tracking and scalable measurement
- Sustainability consultants for complex situations – Specialists become necessary when operations are complex, when tackling challenging Scope 3 emissions, or when preparing for external verification and assurance processes
- Hybrid approaches combining tools and expertise – Many organisations use software for routine data management whilst engaging consultants for methodology development or target-setting through SBTI, balancing efficiency with expert guidance
The difference between a basic footprint estimate and comprehensive carbon accounting is significant. Simple estimates give you a general idea, but serious reduction strategies, regulatory compliance, or stakeholder reporting require detailed, defensible calculations with clear documentation. As your sustainability maturity grows, you’ll likely progress from simple calculators to more sophisticated tools, potentially combining software platforms for data management with consultant expertise for strategic guidance and verification. This evolution reflects the increasing sophistication of your climate action, ensuring your measurement approach keeps pace with your ambitions and stakeholder requirements.
