What is carbon footprint

Carbon footprint is a metric used to measure an organization’s climate impact by quantifying greenhouse gas emissions in terms of CO₂ equivalent (CO₂e).

In a business context, a company’s carbon footprint includes all emissions generated by its operations, both direct and indirect. This approach provides a comprehensive view of environmental impact and helps identify key areas for improvement.

The most widely used international framework is the GHG Protocol, which defines clear standards for carbon footprint calculation and GHG emissions reporting. It classifies emissions into three main categories—Scope 1, 2, and 3—covering both operational boundaries and the entire value chain.

Understanding your carbon footprint is not just about environmental responsibility—it is increasingly essential for risk management, stakeholder transparency, and market competitiveness.

What a corporate carbon footprint includes

A company’s carbon footprint includes all greenhouse gas emissions generated across its activities, from internal operations to the broader supply chain.

These emissions fall into two main categories:

  • Direct emissions, generated from sources owned or controlled by the company (e.g. fuel combustion in facilities or company vehicles)

  • Indirect emissions, related to purchased energy or value chain activities such as suppliers, transportation, product use, and end-of-life

To classify emissions in a structured way, the GHG Protocol defines three levels:

  • Scope 1: direct emissions from owned or controlled sources

  • Scope 2: indirect emissions from purchased energy (electricity, heat, steam)

  • Scope 3: all other indirect emissions across the value chain

In most companies, Scope 3 represents the largest share—often more than 70–80% of total emissions. For this reason, effective carbon footprint management requires an extended perspective that includes suppliers, logistics, and product lifecycle.

How to calculate a company’s carbon footprint

Carbon footprint calculation is a structured process used to quantify greenhouse gas emissions generated by an organization’s activities. It is based on international standards such as the GHG Protocol, which provides guidelines for data collection, processing, and reporting.

In addition to the GHG Protocol, companies can align with standards such as:

  • ISO 14064 (organizational emissions)

  • ISO 14067 (product carbon footprint)

These frameworks ensure consistency, traceability, and data reliability.

To obtain accurate results, the process typically includes the following steps:

1. Define organizational and operational boundaries

The first step is identifying which entities, locations, and activities are included. This ensures a clear and consistent reporting perimeter.

2. Collect activity data

Companies must gather data related to their operations, including:

  • fuel and energy consumption (Scope 1)

  • purchased electricity (Scope 2)

  • transportation, suppliers, waste, and product use (Scope 3)

Data quality is critical to ensure accurate results.

3. Apply emission factors

Collected data is converted into emissions using standardized emission factors from recognized databases such as DEFRA, ISPRA, or Ecoinvent.

4. Calculate emissions and build the GHG inventory

The result is a complete emissions dataset broken down by Scope, forming a GHG inventory used for monitoring and reporting.

5. Reporting and compliance

The final data can be used for reporting under frameworks such as CSRD, ESRS, or GRI, and for third-party verification.

A structured carbon footprint calculation allows companies not only to measure their impact, but also to track it over time and identify improvement opportunities.

Key challenges in carbon footprint calculation

Despite well-defined methodologies, carbon footprint calculation often involves significant operational complexity.

Fragmented data
Relevant information is typically spread across multiple departments, making data collection slow and unstructured.

High risk of manual errors
Excel-based processes increase the risk of inconsistencies, duplication, and inaccuracies.

Scope 3 complexity
Scope 3 is the most challenging area, requiring supply chain engagement and access to often unavailable or estimated data.

Constant updates of emission factors
Using outdated emission factors can lead to inaccurate and non-compliant results.

Audit and compliance challenges
Without a structured system, preparing for audits becomes difficult—especially with regulations like CSRD.

Why measuring carbon footprint matters

Measuring a company’s carbon footprint is not just a compliance exercise—it is a strategic lever for improving performance and competitiveness.

Better understanding of environmental impact
Carbon footprint calculation helps identify high-impact activities and inefficiencies.

Regulatory compliance
Frameworks like CSRD require transparent emissions reporting. Accurate data is essential.

Access to capital and market opportunities
Investors and partners increasingly evaluate ESG performance. A structured approach improves positioning.

Improved reputation
Transparent communication strengthens stakeholder trust and brand credibility.

Strategies to reduce carbon footprint

Once emissions are measured, companies can implement structured decarbonization strategies.

Energy efficiency
Improving energy efficiency reduces both emissions and costs.

Renewable energy adoption
Switching to renewable energy sources is one of the most effective ways to reduce Scope 2 emissions.

Supply chain optimization
Engaging suppliers is essential to address Scope 3 emissions.

Eco-design and lifecycle thinking
Redesigning products reduces emissions across their entire lifecycle.

Setting decarbonization targets
Aligning with frameworks like SBTi (Science Based Targets initiative) enables measurable and credible targets.

Risks of not measuring emissions

Companies that fail to manage their carbon footprint face multiple risks.

Regulatory risks
Evolving regulations such as CSRD and CBAM introduce stricter requirements.

Competitive risks
Companies may be excluded from supply chains or public tenders.

Reputational risks
Lack of transparency can damage stakeholder trust.

Operational and financial risks
Without visibility, inefficiencies and cost-saving opportunities remain hidden.

Measuring a company’s carbon footprint has become a critical step to understand its environmental impact, comply with regulations such as CSRD, and improve ESG performance.

More and more organizations are adopting structured approaches to carbon footprint calculation—not only to meet reporting requirements, but also to identify inefficiencies, reduce operational costs, and define effective decarbonization strategies.

However, calculating a carbon footprint can be complex: from data collection to managing Scope 1, 2, and 3 emissions, all the way to building a GHG inventory aligned with international standards such as the GHG Protocol.

In this guide, we’ll explore what carbon footprint is, how to calculate it effectively, and how to optimize the process by reducing errors, time, and operational complexity.
