Measure the impact of your circular strategies on GHG emissions with CTI Tool v3.0’s new feature!

The GHG Impact Indicator in the new ‘Impact of the Loop’ module shows you how you can reduce your upstream GHG emissions and supports you in prioritizing circular strategies for maximal CO₂ savings.


The aim of assessing Greenhouse Gas (GHG) emission impact is to provide companies with a high-level indication of the GHG savings they may obtain by applying circular strategies. This information can be used to better understand carbon footprint benefits, evaluate trade-offs and help prioritize circular improvements.  

The information provided by the GHG Impact measurement highlights potential for improvement and is based on the company’s current material circularity performance compared to full material circularity.  


In this page you will find useful resources to get the best experience from this new module on the CTI Tool: Explanation video, sample data set in case you don’t have data for an assessment available at the moment and a sample report. 

We are using the Eco Invent database (version 3.8) to fuel the calculation (allocation cut-off by classification). The emission factors used are global averages based on a market approach where available. Factored into these values are the processes of virgin mining (linear), collection and recycling (circular) and transport. The difference in emissions between virgin-mined materials and recycled materials is determining the amount of kg CO2-equivalent that you’re saving by sourcing your materials in a circular fashion. For an overview of all data points considered, please review figure 15 on page 61 of the CTI V3.0-framework that can be downloaded here.
