Procurement with the CO₂ Performance Ladder 4.0: from policy to results 

        

By using the CO₂ Performance Ladder as a Best Price-Quality Ratio (BPQR) award criterion in a tender, you encourage CO₂ reduction during the delivery of the project. From January 2027 it will be mandatory to use version 4.0 of the CO₂ Performance Ladder in procurement. In this blog you can read how…

Insight into your value chain: getting started with a value chain analysis 

        

A value chain analysis helps you determine where the most emissions in your chain occur and where the greatest reduction opportunities lie. This analysis is an important instrument within the CO₂ Performance Ladder for giving substance to ‘cross-scope’ thinking. In this blog we explain how, both within and beyond the boundaries of your own…

To prepare Amsterdam for major climactic changes the CO₂ Performance Ladder is a guiding principle in Amsterdam’s public procurement. Amsterdam and its partners show us how they work with the Ladder. Over the last 14 years, the CO₂ Performance Ladder has developed into a key Green Public Procurement (GPP) tool and the number one CO₂ management system in the Netherlands and Belgium. To support the implementation of the CO₂ Performance Ladder across Europe, our testimonials represent a selection of stories and examples from the history of the Ladder since 2009. They collect the lessons we have learned: what is needed to successfully implement the Ladder, and what benefits does it bring?
