Navigating Scope 3 Information Requests from Customers: A Supplier’s Perspective

Scope 3 Suppliers

Scope 3 information requests. In the contemporary business landscape, the push towards achieving net-zero emissions has seen a significant shift in how companies interact with their supply chains. Larger customer businesses, driven by sustainability goals and regulatory pressures, are increasingly requiring their suppliers to disclose detailed carbon footprint data, specifically Scope 3 emissions, which pertain to indirect emissions that occur in a company’s value chain. For suppliers, particularly those servicing a vast array of customers across multiple products and services, this new demand presents both challenges and opportunities.


The Challenge of Diverse and Complex Questionnaires

One of the primary hurdles for suppliers is the sheer volume and complexity of Scope 3 information requests questionnaires being received from various customers. Each customer, in their quest for sustainability, sends out detailed and often uniquely structured questionnaires aiming to gather comprehensive data on the supplier’s carbon footprint. This diversity not only makes the process time-consuming but also imposes a significant cost burden on suppliers, who must allocate resources to complete each questionnaire to the customer’s satisfaction.

Furthermore, the underlying threat that non-compliance could lead to a severance of business relations adds a layer of pressure. Customers typically accompany these questionnaires with polite, yet firm, notices emphasizing their commitment to achieving net-zero emissions and the expectation for their suppliers to support this journey. The implication is clear: suppliers who fail to engage or provide satisfactory responses risk losing their business to competitors who are more aligned with these sustainability goals.


The Supplier’s Strategy: Getting Ahead of the Curve

For suppliers, the solution lies in proactively understanding and accounting for their carbon footprint, using the guidelines set out by the Greenhouse Gas Protocol. This involves a detailed assessment of all major products and services, identifying the direct emissions (Scope 1), indirect emissions from purchased electricity (Scope 2), and all other indirect emissions (Scope 3) that occur in the value chain.

The strategic move for suppliers is to compile this information into a standardised, product-specific report that details the carbon footprint of each significant product or service. This report should transparently outline the composition of the product’s emissions across Scopes 1, 2, and 3, the supplier’s plans for emission reduction, and critically, the timeline for achieving these reductions.


The End of the Line: A Standardized Approach

By adopting a standardized approach to reporting, suppliers can streamline the information-sharing process. Rather than responding to hundreds of unique questionnaires, a supplier can provide a comprehensive statement on the carbon footprint of their products, how these figures are calculated, and what steps are being taken to reduce emissions to zero. This not only saves time and resources but also positions the supplier as a proactive and responsible participant in the global effort to combat climate change.

Moreover, any reasonable customer should recognise the value in receiving a detailed, standardised report that aligns with the Greenhouse Gas Protocol’s accounting framework. This not only satisfies their immediate need for data but also fosters a culture of transparency and collaboration between customers and suppliers, crucial for achieving long-term sustainability goals.



As the business world moves inexorably towards a more sustainable future, the role of suppliers in this transition cannot be understated. By taking a proactive approach to carbon footprint reporting, suppliers can not only meet the demands of their diverse customer base but also contribute significantly to the global net-zero mission.

This shift towards standardized, transparent reporting is not just about compliance; it’s about leading the charge in a collective journey towards a more sustainable, low-carbon economy.
