2 European average, based on an independent ISO-compliant life-cycle assessment for Europe (EU 27+3). CO₂e emissions reduction differs by country, mainly as a result of variations in end-of-life schemes (recycling, incineration, landfilling rates) and energy sources. Based on currently available country-specific extensions of the Europe LCA, CO₂e emissions reductions are up to 90% for Germany, up to 64% for France, up to 54% for Italy, up to 41% for Spain, and up to 72% for Austria.
