A net positive carbon impact

Getting the proportions right

In 2017 ROCKWOOL sold building insulation products that in their lifetime will save globally the equivalent of the annual carbon emissions of Denmark, Norway and Sweden together. Our sold technical insulation products save even more in their lifetime - equivalent to Germany’s annual carbon emissions.

Getting the proportions right 

Through our insulation products we have truly significant positive impact on the climate change:  

  • Our building insulation sold in 2017 will save 850 terawatt-hours of heating energy during its lifetime and as a result save 190 million tonnes of CO2 emissions. This is equivalent to 80 times the carbon emitted in its production.
  • Our technical insulation sold in 2017 will save more than 5,000 terawatt-hours heating energy during its lifetime and as a result save 1.1 billion tonnes of CO2 emissions. This is equivalent to 4000 times the carbon emitted in its production.

We are committed going forward to minimizing our own carbon emissions in production and maximizing the saved energy and carbon through the use of our products. 

How is the saving calculated?

To assess the energy and carbon savings from the usage of sold ROCKWOOL building and technical insulation products, there is a need for a robust and transparent calculation methodology. Therefore, ROCKWOOL asked Ecofys, a Navigant Company, to develop a methodology and calculate the energy and CO2 emission savings of its building and technical insulation. Ecofys developed the methodology independently of ROCKWOOL and has validated that the 2017 savings were calculated by ROCKWOOL in accordance with the methodology..
