CO2 Module

What is the CO2- Module?

With the growing global requirements for the sustainability of building materials, the CSC has further developed its certification system.

Following the introduction of the new highest certification level “Platinum” and the publication of a so-called “R-module” for the use of concrete with recycled aggregates, the CSC has now introduced an additional CO₂ module.

The aim is thus to create further transparency with regard to the greenhouse gas (GHG) emissions associated with concrete production. CO₂-optimized concretes are divided into four classes – with a reduction in GHG emissions [kg CO₂ equivalents per m³ of concrete] of 30, 40, 50 and 60 % compared with a regional reference value. In order to obtain certification, the concrete plant must fulfill various other requirements in addition to the CO₂ reduction in comparison to the reference value.

For example, the concrete plant must also have at least a CSC certificate of the silver certification level. Since the major share of greenhouse gas emissions is attributable to cement production, the concrete manufacturer must also demonstrate coverage of its cement product chain of at least 75% CSC-certified cement. Other requirements include proof that the concrete plant monitors the greenhouse gas emissions of its core processes and the existence of a documented system of factory production control (quality management).
