Carbon Footprint studies for Lindab´s products
The construction industry is increasingly demanding access to information about products’ carbon emissions during their lifetime, referred to as the Carbon Footprint. Buildings account for 36 percent of the EU’s total greenhouse gas emissions. Building materials constitute a part of this. To reduce a building’s impact on the climate, it is important to be able to manage and to know the material’s carbon footprint.
Lindab is working to develop Carbon Footprint studies for a large proportion of the Group’s products. The studies, which include the products’ impact on the environment, are presented notably in environmental product declarations and other product information. The calculations are performed by an external party, WSP, and are made from “cradle to grave”, i.e. from the extraction of raw materials until the product leaves Lindab’s factories. In 2011, all of Lindab’s product groups will be covered by Carbon Footprint studies.
So far, outcomes from the studies have shown positive results for Lindab’s products and the materials used. The material accounts for much of the Carbon Footprint, i.e. the production of steel. Manufacturing, transportation
and packaging materials comprise less than 10 percent of the products’ total Carbon Footprint.
CARBON FOOTPRINT STUDIES
Based on calculations according to Carbon Footprint studies, the GWP
(Global Warming Potential) for a standard home is 6.36 tonnes. This
value is based on the approximate consumption of materials for steel
components in a detached house measuring 130 m2 with a ventilation
system, frame, roof and roof drainage from Lindab. This can be compared
with a return flight between Sweden and Thailand, resulting in
emissions of 1.5 tonnes per person. A house built using Lindab’s products
therefore roughlycorresponds to a vacation for a family of four.
