In 2018 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 2018 will save 900 terawatt-hours of heating energy during its lifetime and as a result save 200 million tonnes of CO2 emissions. This is equivalent to 100 times the carbon emitted in its production.
- Our building insulation saves nearly 70 times the PM emissions related to the production of ROCKWOOL insulation during the 50 years average lifetime of a building.
- Our technical insulation sold in 2018 will save 5400 terawatt-hours heating energy during its lifetime and as a result save 1.2 billion tonnes of CO2 emissions. This is equivalent to approximately 5800 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, carbon and air emission savings from the usage of sold ROCKWOOL insulation products, there is a need for a robust and transparent calculation methodology. Therefore, ROCKWOOL asked Navigant to develop a methodology and calculate the energy and CO2 emission savings of its building and technical insulation as well as the and the SO2, NOx, and particulate matter (PM) for building insulation. Ecofys developed the methodology independently of ROCKWOOL and validates that the annual savings are calculated by ROCKWOOL in accordance with the methodology.
