The CO₂ Performance Ladder is an instrument that helps organizations reduce their carbon emissions in the organization, in projects and in the business sector. With a certificate on the Ladder, organizations can receive an award advantage for their registration on tenders. The instrument is used as both a CO2 management system as well as a procurement tool. Organizations that obtain a certificate on the Ladder will experience this as an investment that is immediately returned in terms of low energy costs, material savings and innovations. The Ladder’s main objective is to stimulate organizations to gain insights in their CO2 emissions, and to continuously seek opportunities to cut back these emissions in the organization and consequently within projects. The CO2 Performance Ladder was originally developed by the Dutch railway concern ProRail in 2009. Since 2011 the system is owned and managed by the Foundation for Climate Friendly Procurement and Business (SKAO).
