CO2 Performance Ladder

Climate change is one of the biggest challenges of the coming decades, including for companies. On the basis of our social function as a multidisciplinary engineering firm, we implement sustainable entrepreneurship practices in various ways.

In addition to many one-off initiatives, we are committed to reducing our CO2 emissions through a variety of actions, both in our projects and in our business operations. The CO2 Performance Ladder is also the appropriate instrument for mapping our emissions inventory and working with clients on CO2 reduction.

What is the CO2 Performance Ladder?

The CO2 Performance Ladder is an initiative of the Stichting Klimaatvriendelijk Aanbesteden & ondernemen (Foundation for Climate Neutral Procurement and Enterprise), which was created to encourage companies to act in a CO2 conscious manner, primarily in the areas of energy conservation, efficient use of materials and use of renewable energy.

The CO2 Performance Ladder is a CO2 management system that comprises five levels. Up to and including level 3, an organization works on the emissions within its own organization (and all projects). From levels 4 and 5 onwards, CO2 emissions in the chain and sector are also included.

In 2022, SBE achieved level 3 on the ladder. We aim to move to level 4 on the CO2 Performance Ladder in 2025.

The requirements for the CO2 Performance Ladder are divided into 4 perspectives:

Perspective A: insight
Determining energy flows and the CO2 footprint

Emissions over the past few years were mapped and translated into a CO2 footprint to gain insight into our CO2 emissions. These reports include our various energy flows and consumption within our office buildings.

To date, we have not had any projects with a CO2 award advantage.

Perspective B: reduction
Developing ambitious targets for CO2 reduction

SBE has set the following targets to reduce CO2 emissions, based on the CO2 emissions inventory:

*By switching to renewable energy in the Sint-Niklaas office, we aim to achieve a 50% reduction in scope 2 emissions in 2025 compared to 2021. However, we expect an increase in electricity consumption in the coming years because the share of electric cars in our fleet will only increase. The consumption (in kWh) of our employees who charge at home is considered gray electricity, which will greatly increase scope 2 emissions.

We are taking the following measures to achieve these goals.

  • For example, we have 458 solar panels on the roof of the office in Sint-Niklaas to generate renewable energy.
  • We are becoming more sustainable through electrification of our company vehicle fleet and installation of charging stations
  • We encourage and facilitate home office whenever possible
  • We are committed to CO2 reductions in our projects by providing services and tools that prioritize sustainability (e.g. SPIRIT and ECI calculations). In terms of residual power, we are switching to green power for offices under our own management.

More information on this topic is available in the document “plan of approach, incl. reduction goals”.

Perspective C: transparency:
Structural communication about our CO2 policy

We make our CO2 efforts visible and accessible both internally and externally. This ensures that not only our own employees but also other companies, clients, partners and suppliers have an accurate picture of our ambitions.

We create support and awareness of CO2 emissions through our internal communication channels. We highlight our efforts and goals at least twice a year.

Wherever possible, we draw attention to sustainability and CO2 awareness through this website and our social media channels.

Perspective D: participation:
Participation in sector initiatives on CO2 reduction

O2he sector initiatives in which SBE participates are explained in more detail in the document Overview of Initiatives, which is also available on SBE’s SKAO page.

Sustainability documents

As part of our compliance with the CO2 Performance Ladder and in the context of transparent communication regarding our sustainability efforts, we publish various sustainability documents on our website. Here you can find our carbon footprint, emission reduction goals, and energy management action plans, among other information

Independent review

Each CO2 Performance Ladder certified institution is audited annually by an independent and accredited certifying body.

As a certified organization, SBE can therefore guarantee that we are using an operational CO2 management system for our organization and our projects that is also reviewed annually in terms of ambitions, reduction and continuous improvement.

  • Is the CO2 Performance Ladder already in use in Belgium?

    A pilot phase is currently underway in Belgium with the CO2 Performance Ladder in 24 tenders. Chances are therefore very high that the CO2 Performance Ladder will also become a fixed value in Belgian construction tenders. 
  • Why do you use the CO2 Performance Ladder instead of other sustainability initiatives?

    We prefer the CO2 Performance ladder because it contains several interfaces with other sustainability initiatives such as the SDGs, ISO 50001 (energy management), Duurzaam GWW. The CO2 Performance Ladder is also a widely used tool in tenders in the Netherlands so it can be of great added value to our Dutch department due to the CO2-related award advantage on the award price of acquired assignments.
