What it is

Scope 3 Emissions Assessment, without the jargon

Scope 3 covers indirect value-chain emissions across the 15 categories of the GHG Protocol Scope 3 Standard — from purchased goods and services, capital goods and transport upstream, to product use and end-of-life downstream. We screen all categories for relevance, then quantify material ones using spend-based, average-data or supplier-specific methods.

Why it matters

Why companies act on this

  • Scope 3 is typically the largest share of a company’s total footprint
  • SBTi and CDP both expect material Scope 3 categories to be measured and targeted
  • It exposes supplier, logistics and product-use hotspots that on-site accounting misses
