Our plan to reduce CO₂

Colruyt Group reduced its relative greenhouse gas emissions by more than 40% compared to 2008. We are proud of what we have already achieved and remain committed to working together to make a positive difference. Find out the essence of our reduction plan, from analysis and reduction to capture.

1. Analyse

Every day, we work to minimise our impact on climate change, always with an eye on long-term results. To achieve this, we need to have a good overview of both our emissions and our approach.

We monitor our greenhouse gas emissions (such as CO2, methane and ozone) according to three scopes defined by the internationally recognised Greenhouse Gas (GHG) Protocol.

Step 1: ANALYSIS - monitoring our CO2 emissions
Scope 1

The direct emissions caused by our own building-, transport- and production-related activities.

Scope 2

The indirect emissions released when generating the energy we purchase.

Scope 3

The indirect emissions – linked to our activities – that occur in the value chain, both at our suppliers and customers. 

Colruyt Group drew up a CO2 balance sheet for the first time in 2008. The CO2 reduction projects were launched in 2011-2015. Initially, we focused on greening our electricity and reducing emissions caused by cooling and mobilityheating was added later. 

We stick to our basic principles in this

  • Avoiding emissions
  • Reducing emissions
  • Finding solutions with the smallest impact on climate change

2. Reduce

The projects and initiatives of this reduction programme have allowed us to present some great results In recent years, our greenhouse gas emissions (scope 1 and 2) have dropped in both relative and absolute terms. Faster than expected, we have managed to meet our reduction target: 40% reduction of greenhouse gas emissions by 2030, versus base year 2008 and relative to revenue. With -42,4%, this mission is a huge success. We would like to continue this trend. We are committed to setting new emission reduction targets by the end of 2022 in accordance with the criteria and methodology of the Science-Based Targets initiative (SBTi).

Step 2 - REDUCTION - reducing our CO2 emissions

Some of the things we did within our own operation and activities: scope 1 and 2


Since 2017, our food stores have been switching to cooling systems using natural refrigerants such as propane. They have less impact on global warming than the conventional variant. The switch will be completed by 2030 and will result in a significant reduction in emissions.

For chilled transport, Colruyt, Bio-Planet and OKay work with climate-friendly liquid ice containers, both for fresh produce and for frozen foods. At Collect&Go, our newly developed cool box also allows us to use fewer traditional CO2 refrigerated carts.

By 2030 90 % of our stores will be low-energy stores


Many food stores are already using heat recovery. The residual heat from cooling is used as heating and often the step towards a fossil fuel-free store is made. Heat pumps will also further reduce emissions from heating.


We are fully committed to cleaner logistics with trucks, vans and delivery trucks running on alternative fuels. Our company cars also increasingly run on greener fuels such as CNG, electricity and hydrogen. Therefore, we invest in the necessary infrastructure such as charging stations at the various sites.

Some of the things we did to help in the value chain: scope 3

We make considered choices with a view to emission reduction in the construction (materials) of the buildings and the transport of suppliers, customers and workers. Examples:

  • Store façade with a fully reusable click system;
  • Less lorry trips by switching to barge transport in Belgium;
  • More electric charging points at our store car parks;
  • Millions of less car kilometres by encouraging workers to cycle or commute to work.

With the Eco-score as lever and together with suppliers, we want to actively work towards lower CO2 emissions and a lower environmental footprint of the products in the stores.

3. Capture

In addition to reducing our emissions we will also remove the equivalent of our remaining emissions from the atmosphere through forest planting. By combining further emission reductions and capturing the remaining emissions, our group aims to achieve net zero emissions from 2030 onwards within scope 1 and 2 of the GHG Protocol.
