Why Scope 3 pressure is landing on small businesses next
Large corporations report on Scope 3 emissions across their supply chain. That reporting flows downhill: their suppliers, most of them SMEs, are being asked for data they have never collected before.
The reporting cascade
Under frameworks like the EU CSRD and California's SB 253, large companies must now disclose Scope 3 emissions across their value chain. Scope 3 covers everything a company does not directly own: purchased goods and services, business travel, distribution, and the end use of products sold.
For a large buyer, the fastest way to close that data gap is to ask suppliers. Small and mid-sized businesses that sell into those supply chains are now being handed questionnaires, sustainability scorecards, and RFP prerequisites that assume basic ESG infrastructure they do not have.
What this means in practice
- Losing tenders because a checkbox on emissions data was left blank.
- Being deprioritized in supplier reviews without a clear reason.
- Rushing to answer questionnaires without a shared internal understanding.
A calmer starting point
A structured self-assessment gives an SME a shared internal picture before the next buyer request arrives. Knowing where the business already meets a standard, where it partially does, and where it does not, turns a scramble into a plan.
That is the practical case for a framework like RBP: not to satisfy any single reporting regime, but to build the internal language and evidence base that makes every future buyer conversation faster.
