The new CO₂ Performance Ladder 4.0: On the road to zero emissions

Climate change demands concrete action. Companies and public authorities are seeking effective ways to reduce their CO₂ emissions. In the Netherlands, the CO₂ Performance Ladder has become the leading sustainability tool for organisations serious about CO₂ reduction. With the launch of version 4.0, the standard has been further refined and aligned more closely with international climate goals, such as the Paris Agreement and the Corporate Sustainability Reporting Directive (CSRD).

The CO₂ Performance Ladder was first developed in 2009 as a tool to help companies and public bodies systematically reduce their CO₂ emissions. Since then, it has grown into a leading sustainability instrument in the Netherlands, with over 8,000 certified organisations and more than 350 contracting authorities using it as an award criterion in procurement.

What makes the CO₂ Performance Ladder unique is its dual role: it functions both as a management system and a procurement tool. As a management system, it provides a structured approach for reducing CO₂ emissions within the organisation and across the supply chain. As a procurement instrument, it gives certified organisations a competitive edge in tenders, as many public authorities award advantages for certification on the Ladder. The CO₂ Performance Ladder offers practical guidance and obliges certified companies to be transparent and continuously improve their CO₂ performance. Research has shown that certified organisations reduce their emissions twice as fast as non-certified ones, underlining the practical effectiveness of the tool.

Version 4.0 of the CO₂ Performance Ladder introduces several significant changes compared to the previous version. The most notable new feature is the mandatory climate transition plan for organisations aiming for certification at the higher levels. This plan acts as a strategic roadmap, outlining how organisations will reach net zero emissions by 2050 at the latest. It includes concrete interim targets for CO₂ reduction, specific measures to achieve these goals, collaborative initiatives across the value chain, and obligations for monitoring and reporting to ensure continuous evaluation and improvement. This requirement encourages organisations to look beyond their own operations and adopt a holistic approach to reducing emissions across their entire chain.

For organisations beginning their journey with the CO₂ Performance Ladder, the process starts with a baseline measurement of current CO₂ emissions. This typically includes Scope 1 (direct emissions), Scope 2 (indirect emissions from energy use), and relevant Scope 3 emissions (other indirect emissions within the value chain). Based on this analysis, organisations can determine which step is feasible and which measures will have the greatest impact.

An important consideration during implementation is involving the entire organisation. Whereas sustainability was once often the responsibility of a single individual, version 4.0 highlights the importance of broad support and engagement across all departments. This can be achieved by appointing key individuals responsible for rolling out sustainability measures within their own teams or areas.

When developing the climate transition plan, it is wise to consider both short-term actions (such as improving energy efficiency) and long-term solutions (such as process innovation). The plan should be realistic, yet ambitious enough to contribute meaningfully to climate goals. Many organisations find it useful to collaborate with peers in their sector or join existing sector-wide initiatives.

The Ladder not only encourages organisations to reduce their own CO₂ emissions but also to actively engage suppliers and partners in the process. This is essential, as a large share of emissions falls outside an organisation’s direct control but can still have a significant impact. By working with value chain partners and establishing joint reduction initiatives, organisations can achieve greater overall reductions.
