Overview

As businesses and public organisations strive to take impactful climate action, it's essential to pay attention to Scope 3 emissions. These indirect emissions from your upstream and downstream activities like purchasing goods and services or the use phase of products can make up 70-90% of your carbon footprint. 

Our introductory guide outlines key considerations businesses and public bodies must bear in mind when measuring and reporting Scope 3 emissions. 

We answer key questions: 

  • What exactly are Scope 3 emissions and why do they matter? 
  • What benefits can a deep understanding of your Scope 3 emissions and reductions bring? 
  • How can you start to collect your Scope 3 data effectively? And what steps should you take to improve your data quality? 
  • How can you work with suppliers and other partners to improve your Scope 3 footprint, contribute towards your sustainability goals and measure progress?
