Introduction (Article first published in ILM, January-February 2015 edition)
Global climate change has come more and more into focus during the last few years. A major source contributing to global climate change is the emissions of greenhouse gases such as carbon dioxide and methane into the atmosphere. As a consequence, more attention is now given to Environmental Footprints, such as Product Carbon Footprint (PCF), which has been an important factor in assessing the environmental sustainability of products. A PCF describes the sum of greenhouse gas emissions accumulated during the full life cycle of a product and is therefore a measure of the absolute climate impact of a product and its use.
