The impact of climate change to biosphere and the human civilization living therein are widely discussed as is the need to reduce the consumption of energy and materials – measured in footprints. Despite of that the means on how to reduce footprints and the difficulties going along with that are lesser discussed.The assessment of CO2 Footprints during all phases of its production and existence (Life Cycle Assessment) is embedded in the legally required of non-financial reporting for companies. This talk is intended to provide background on non-financial reporting and how that relates to footprints and risks. Of course reporting is not l´art pour l´art. It is intended to reduce the impact of an activity – Ecodesign and it impacts the value of companies. The intent is to discuss in more detail how reporting is done, how (CO2-) Footprints are derived, ways to reduce footprints and how the related activities influence the value of companies.
