Cork components reduce the carbon footprint of flooring solutions

The cork components used in Amorim NRT®62 flooring solution, with and without a vapour barrier, have been shown to have a negative carbon balance.

Amorim NRT®62 cork components, with and without a vapor barrier, by Amorim Cork Composites, that have been especially developed for the flooring industry, make a positive contribution to lowering the carbon footprint of flooring manufacturers’ production processes. This is because Amorim NRT®62 cork-based components have a negative carbon balance. They also prevent the transmission of vibrations to the slab, thereby reducing impact noise.

Negative carbon balance

According to a life-cycle assessment conducted by the consultancy firm, EY, the carbon balance of the component Amorim NRT®62 flooring solutions without a vapour barrier is -11.8kg CO2 eq/m2, whereas the carbon balance of the component for Amorim NRT®62 flooring solutions with a vapour barrier is -10.5kg CO2 eq/m2. Since the associated carbon sequestration of the cork oak forest exceeds the CO2 emissions resulting from production, these solutions are an excellent option for flooring manufacturers who aim to strike a balance between performance and environmental sustainability.

As a 100% natural, recyclable and renewable raw material, cork helps reduce the possible environmental impacts of flooring solutions that use Amorim NRT®62 components. These differences are especially visible when we compare these products supplied by Amorim Cork Composites with other components that use raw materials solely from a synthetic source, such as polyurethane and/or polyethylene foams.


The environmental footprint study of Amorim NRT®62 flooring components was conducted by EY using a Life Cycle perspective, which considered the carbon sequestration of the cork oak forest, based on the cradle-to-gate approach. This approach contemplated the environmental impacts of all activities - from the extraction of the raw material, through production of all components up until the factory gate. The methodology of EY's studies was based on the ISO 14040/44 standards, complemented by the guidelines of the International Reference Life Cycle Data System (ILCD). Production data was provided by Amorim Cork Composites, while data on the general production processes associated with the production of raw materials, energy, transport and waste management was obtained from the ecoinvent 3.5 database.
