Three stages of corporate Scope 3 reporting & primary data collection

Three stages of corporate Scope 3 reporting & primary data collectionMeasuring and reducing Scope 3 emissions (GHG emissions associated with the value chain) has become a key area of environmental reporting for most companies. With a surge in the setting of ambitious science-based and net-zero targets, and the increased pressure from investors, regulators and customers, prioritising Scope 3 emissions has never been as important.

Greenstone recently held a webinar on Scope 3 reporting. This article presents a practical case study on how companies are approaching the Scope 3 reporting journey and the common three stages we are seeing the vast majority of our clients, across all industries and all sizes of organisations, go through when it comes to Scope 3 reporting.


Stage one

When a company has been initially measuring and reporting carbon emissions with a focus on accurate Scope 1 and 2 emissions.

For Scope 3 in this stage, generally, people are only focusing on the core Scope 3 categories, or the ones that are straightforward and within their control. This would typically be waste from locations, sites or offices, business travel, and maybe some parts of category three for fuel and energy-related activities.


Stage two

This stage is where we are seeing the wider Scope 3 picture starting to come together, but still in a high-level way. This is when the emissions-screening process would take place and would be where a company still relies on spend data to start assessing wider Scope 3 categories but using this to understand where the material impact areas are.

From here, the number of Scope 3 categories starts to grow. Typically, this starts with purchased goods and services and capital goods.


Stage three

This is the stage where the focus really switches onto the quality of data and the reliance on spending data reduces as companies reach out to suppliers to get more accurate primary data. From here, the categories being tracked, continue to increase.

Although it's likely at this stage that a company will be aiming to track all categories that are relevant to them, it depends on the industry, which will determine which categories will be relevant. For example, a company that creates products and sells products will need to be much more focused on these categories from the outset. Similarly, companies that have material investments or franchises will look to engage in those categories earlier in their reporting.



How Greenstone’s ESG solutions can help support the Scope 3 reporting journey

Greenstone’s suite of sustainability, supply chain and investor ESG software solutions provide an integrated approach to addressing the challenge of Scope 3 emissions calculation and reporting. Providing a central hub for the collection and aggregation of Scope 3 data across all 15 Scope 3 categories, Greenstone’s solutions support businesses on their Scope 3 reporting journey, whether they are just starting out or they have been reporting in this area for years.

In Stage one and Stage two outlined above, our clients are mainly using our ESG software platform (Greenstone Enterprise) to coherently streamline data from within their operations across Scope 3.

In Stage three, as we start to get a combination of primary data from suppliers or investments, we then transition into using Greenstone’s other solutions as well. This is where our clients are using SupplierPortal and InvestorPortal to collect primary data from their suppliers and portfolio companies and automate the collection of data for an accurate Scope 3 emissions inventory.

SupplierPortal and InvestorPortal GHG wizards can be used to collect primary carbon data from external organisations. The GHG emissions wizards are a dedicated Scope 3 functionality in those two solutions, that can be used by companies to push out requests to suppliers or investments to collect primary Scope 3 data.
