Tendering: Reliable CO₂ Data

An accurate CO₂ calculation starts with reliable data. But where do you get it?
Below, discover the most important sources for CO₂ emissions per product and how to use them effectively in tenders.

1. Government Databases

The Belgian government provides tools that help calculate the environmental impact of construction materials.

TOTEM – This is the official Belgian tool for the environmental performance of construction materials, including CO₂ emissions per unit. TOTEM helps you compare materials based on their impact, allowing you to make more sustainable choices.

2. Supplier Data

Many suppliers provide product-specific CO₂ data, such as:

  • CO₂ emissions during the production and transport of construction materials.
  • Information about recycled or renewable materials.
  • Environmental impact reports and certifications.


By requesting this data from your supplier, you obtain realistic figures that can be directly applied in your tender calculations.

3. Commercial Databases and Research Companies

Some specialized companies manage extensive databases with CO₂ data and offer in-depth analyses, such as:

EPD (Environmental Product Declarations)

Standardized documents that record the environmental impact of construction products.

LCA (Life Cycle Assessment)

A complete analysis of a product’s CO₂ emissions, from raw material extraction to end of life.

Commercial databases and studies provide additional insights and accurate data to help you create strong CO₂ calculations for tenders.
