Scope 1, 2, 3 Emissions & Assurance

Understanding emissions categories (Scope 1, 2, 3) and the growing requirements for assurance on sustainability information are foundational to credible climate disclosure.

At a Glance

  • Scope 1: Direct emissions from owned or controlled sources.
  • Scope 2: Indirect emissions from purchased energy.
  • Scope 3: All other indirect emissions in the value chain.
  • CSRD requires limited assurance on sustainability information, potentially moving to reasonable assurance.

Key Principles

  • GHG Protocol-based categorisation
  • Scope 3 value chain emissions
  • Data quality and estimation methods
  • Limited vs. reasonable assurance
  • Assurance readiness

What Companies Should Do Now

  1. 1Review emissions data collection processes and controls.
  2. 2Improve Scope 3 data quality through supplier engagement.
  3. 3Engage with assurance providers early on readiness.
