For years, organizations focused strictly on Scope 1 and 2 emissions—the power they consumed and the fuel they burned. But as global mandates like the CSRD and SEC disclosure rules come online, the spotlight has violently shifted to Scope 3.

Scope 3 encompasses all indirect emissions that occur in the value chain of the reporting company. This includes upstream operations like purchased goods and downstream operations like the use of sold products. For many organizations, this accounts for up to 70% of their total footprint.

The primary hurdle is data collection. Engaging a complex, multi-tiered global supply chain requires more than just sending out a spreadsheet. It requires a structured, easily implementable framework that vendors can realistically adhere to.
