Why get certified

Three business reasons to act now.

The Belgian market is structuring itself around certification. Companies that move now build an advantage that will be very hard to close later.

Win more public contracts, without cutting your prices.

The CO₂ Performance Ladder is an award criterion in Belgian public tenders. Certified companies benefit from a fictitious discount that improves their ranking, without touching their margins.

Access contracts from large private groups.

Carmeuse, Wanty and Eloy have reached Step 3 and prefer subcontractors engaged in the same approach. Without certification, you gradually fall off their radar.

Turn your CO₂ data into a financial lever.

Certification forces you to measure. Tapio helps you understand what that data means for your costs, your risks and your revenue.

What the CO₂PL is

A CO₂ management system with 3 certifiable steps.

The CO₂ Performance Ladder is both a carbon reduction tool and an award criterion in public tenders. It is a progressive certification built step by step, at the pace of your organisation's maturity.

The effort is not all at once: each step lays the foundation for the next. It is a continuous improvement journey, not a box to tick. Handbook 4.0 has been in force since January 2025.

The 4 assessment axes

Each step is audited annually against these four axes.

Insight

Quantify your energy consumption and emissions (scopes 1, 2 and 3), identify the most emitting activities, and analyse the associated value chains.

Reduction

Develop a climate transition plan with short and medium-term targets, and demonstrate that those targets are actually being met.

Transparency

Communicate internally and externally on your CO₂ policy, targets, progress and results. A portion is published on the official CO₂ Performance Ladder website.

Participation

Analyse your knowledge and partnership needs, and actively collaborate with organisations in your value chain to amplify collective impact.
