The Role of Carbon Certificates in Supply Chain Procurement

3 min readJanuary 28, 2026

Supply chain transparency is the buzzword of 2026. Big companies have wrung the efficiency out of their own operations; now they are looking at you.

Scope 3 Audits

You are part of someone else's Scope 3 emissions. When Woolworths, Coles, BHP, or Telstra report their carbon footprint, they estimate supplier emissions.

Primary Data vs Secondary Data

  • Secondary Data (Bad): They guess your emissions based on how much they spent with you (Spend-based method). This is usually inaccurate and high.
  • Primary Data (Good): You give them your actual certificate. This reduces their reported risk and makes you a lower-risk partner.
