The international standards organisation (ISO) is presently working on the new standard ISO 14067 for the CO2 footprint of products in order to quantify and publish the greenhouse gas emissions of products and services as a worldwide standard. In Vienna, Pro Carton President Roland Rex and Univ.-Prof. Dr. Wolfgang Wimmer, Technical University, Vienna, and the co-convenor of the ISO 14067 working party, Dr. Klaus Radunsky, met to discuss developments on the upcoming CO2 footprint of products. Pro Carton is convinced that the new standard will help to position cartonboard even more as a sustainable material for packaging. The CO2 footprint of products determines the total amount of greenhouse gas emissions which can be attributed to a product during its entire lifecycle. A final document is expected by the middle of 2012.
