In the world of corporate sustainability, Scope 3 emissions frequently account for a significant portion of a company’s total carbon footprint. These emissions, originating from sources not directly controlled by the organization but existing throughout its value chain, often represent the most challenging aspect of greenhouse gas (GHG) emissions reporting.

Despite their complexity and the time-intensive effort required to calculate them, understanding and managing Scope 3 emissions is essential for organizations who want to reduce their overall climate impact.

In this article, we will explore the challenges faced when measuring and reporting Scope 3 emissions and discuss potential solutions to them. These are the hurdles you’ll likely encounter when calculating your company’s GHG emissions, so it’s best to be prepared for what lies ahead.

CO2 Footprint Calculation Main Challenges and How to Overcome Them

1. Data Availability and Quality

One of the most significant challenges is the lack of access to reliable data across a company’s value chain. Scope 3 emissions involve upstream and downstream activities, making it difficult to gather consistent, accurate data from third parties, suppliers, or clients.

Solution: Companies can improve data availability by establishing strong relationships with their suppliers. Companies can require their suppliers to provide emissions data as part of their contracts, ensuring that this information is consistently tracked.

Many companies struggle to obtain accurate emissions data from suppliers or other third parties. In these cases, companies often resort to using industry averages or estimates to fill in the gaps. While this approach can help move the process forward, it’s crucial to transparently communicate where estimated or average data has been used in the GHG report.

2. Complexity of the Value Chain

Another challenge is the sheer complexity of mapping and understanding the entire value chain. For large organizations with multi-tier suppliers, keeping track of all the processes and their corresponding emissions is a daunting task.

Solution: Simplify your approach by focusing on key emissions categories. A step-by-step approach helps manage this complexity, where companies first map their value chain and identify emission hotspots. By narrowing the focus to major contributors, businesses can prioritize areas with the most significant impact.

If the purpose of conducting a GHG inventory is to find out the largest impact categories, smaller impact categories, especially those that are extremely complex to map, can be left out of the inventory. For instance, if a company is in manufacturing, minor emissions from office supplies like paper, pens, or coffee can be excluded from the inventory in the initial inventories. Of course, documenting this in the GHG report is required to ensure clarity and transparency.

3. Inconsistent Reporting from Suppliers

Inconsistencies in the way suppliers measure and report their own emissions can introduce errors and make Scope 3 calculations unreliable.

Solution: Encourage suppliers to use standardized methodologies, such as the GHG Protocol and EPD and offer guidance on emissions reporting. Creating a system to audit or verify supplier data can also help ensure that the information received is trustworthy.

4. Lack of Internal Expertise

Not all organizations have the in-house skills or knowledge required to carry out a detailed Scope 3 emissions inventory.

Solution: Assign internal responsibilities and invest in building internal expertise over time. Alternatively, when possible, consider engaging external experts to help guide the process. This ensures that the methodology chosen fits your organization’s specific needs and avoids potential mistakes during data collection or calculation.

5. Boundaries and Scope Definition

Companies may struggle with defining the appropriate scope for their Scope 3 inventory. Deciding which categories to include and where to draw boundaries within a complex value chain can be tricky.

Solution: Use a step-by-step approach to clearly define the boundaries at the beginning of the process. This includes setting goal(s) for conducting the GHG inventory, determining which emissions categories are most relevant, what is the timeline for the whole process etc. It is also recommended that businesses document the decision-making process to maintain consistency across future assessments.

Additional Tips

Structured Data Collection

A well-organized data collection process is key to overcoming Scope 3 measurement challenges. Ensure that data collection systems are designed to capture the most accurate information possible, and that responsibilities for gathering this data are clearly assigned within the organization.

If not all the data required for mapping Scope 3 emissions is being tracked today, the first GHG inventory will provide valuable experience and insight into what additional data is needed. Based on this, the company can adjust its data collection model to ensure a more automated and streamlined data gathering process in the following years.

Collaborating with Suppliers

Strong communication with suppliers is essential. Companies can encourage their suppliers to measure and share their emissions data, and even offer guidance or training if necessary. Larger organizations could also consider rewarding suppliers that meet specific sustainability standards.

Additionally, a criterion could be introduced where transparent sustainability information related to the specific product and supplier is required when procuring materials/components or selecting partners. This measure encourages suppliers to focus on their company’s sustainability and motivates them to act responsibly.

Flexibility in Methodology

The GHG Protocol provides a solid framework, but businesses must adapt it to their needs. Flexibility is crucial, especially when faced with missing data or complex supply chains. In such cases, companies may need to use proxies or estimates, but they must remain transparent about their methodologies in the GHG report.
