Scope 3 calculation:

Understanding your company's full Carbon Footprint

Background

For many companies, Greenhouse Gas (GHG) emissions can occur in the value chain rather than in direct operations or purchased energy. Scope 3 calculation and reporting quantifies these upstream and downstream emissions and allows you to gain insight into the climate impact of your value chain. This can then be used as a basis for target setting and decision making.

The GHG emissions of a company can be classified into three scopes:

  • Scope 1: Direct emissions from sources you own or control, such as fuel burned in boilers, vehicles or equipment.
  • Scope 2: Indirect emissions from the generation of purchased electricity, steam, heating or cooling.
  • Scope 3: All other indirect emissions that occur in the value chain, upstream and downstream.

What is Scope 3?

Scope 3 includes activities such as purchased goods and services, transportation and distribution, product use, waste disposal, and employee commuting. In total, there are 15 mutually exclusive categories (see figure below) of Scope 3 emissions which are defined in the GHG Protocol Corporate Value Chain (Scope 3) Accounting and Reporting Standard (also referred to as the Scope 3 Standard). This Scope 3 standard provides requirements and guidance for companies to calculate and publicly report a GHG emissions inventory for their Scope 3.

Why Scope 3 calculation matters

Scope 3 calculation and reporting can be a valuable tool for companies that want to understand the carbon footprint of their entire value chain, rather than just their direct emissions.

Scope 3 calculation and reporting helps companies to:

  • Strengthen data management: Set up effective data management systems for collecting, structuring and maintaining GHG data.

  • Set and track targets: Develop a baseline for setting and tracking emission reduction targets over time.

  • Identify hotspots and reduction opportunities: Identify emissions hotspots and opportunities to reduce emissions. Reducing emissions and improving sustainability performance can result in cost savings, added value and improved reputation.

  • Engage the value chain: Build stronger relationships and promote sustainability throughout the value chain by working closely with upstream suppliers and downstream stakeholders.

  • Meet reporting and regulatory expectations: Meet regulatory requirements and stay ahead of emerging sustainability trends, reporting frameworks and best practices.

The Scope 3 calculation and reporting process in practice

The process of calculating Scope 3 emissions involves several steps:

Identify which of the 15 Scope 3 categories of emissions are most relevant in the company’s value chain.

For each relevant categories, a data collection and reporting approach must be chosen. This should take into account both the feasibility and credibility of the results.

Company wide data is collected involving a range of departments such as procurement, finance, HR and sales. Where needed, suppliers and customers should be engaged to gather data on their own processes and related emissions.

Once the data has been collected, the carbon footprint of each relevant category can be calculated and reported using the defined reporting approach. Together, these results form your Scope 3 inventory.

Updating your Scope 3 emissions

Scope 3 inventories are typically updated on an annual basis, aligned with the company’s reporting cycle. Each update is an opportunity to refine data, expand coverage and adjust methods where needed. This approach allows companies to gradually increase the robustness of their Scope 3 reporting while keeping the process manageable.

Ecomatters support with Scope 3 calculation and reporting

At Ecomatters, we help companies calculate and report on their Scope 3 emissions. We support with the development of GHG inventories, data collection, the implementation and tracking of GHG reduction initiatives, as well as the development of GHG accounting and auditing systems to ensure accuracy and reliability. With over 10 years of experience we understand that every business is different. Therefore we strive to provide tailored solutions that meet the individual needs of our clients.

Due to complex reporting requirements and dependence on external data, Scope 3 calculation is often more challenging than Scope 1 and 2 reporting. Contact us to learn how we can support you.
