Carbon Footprint


Climate change has become one of the major challenges for mankind and the natural environment. Greenhouse gas (GHG) emissions released into the atmosphere in ever rapidly growing volumes are recognised to be responsible for this change. Carbon footprint quantification, analysis and reduction are key to preventing this, for example, by enhancing energy efficiency, mitigating carbon emissions by means of green energy and then compensating for remaining GHG emissions by investing in carbon offsets, with a final goal to becoming carbon neutral. During a product life cycle, energy is required to extract, transport and refine the raw materials, for manufacturing and to distribute the final product and treat the waste at the end of a its useful life.

As fossil energy carriers play the major role for energy supply, any of the above steps is associated with the generation and emission of greenhouse gases (GHG), such as carbon dioxide, methane, nitrous oxide, etc., contributing in turn to the global warming effect, which is measured as the product’s carbon footprint.

Life Cycle Assessment according to ISO 14044 (also covered in the BSI PAS2050) is the state-of-the art methodology to determine your product carbon footprint. Facilitating such a “cradle-to-grave” carbon footprint analysis of your product will disclose your real carbon footprint, reveal reduction potentials and discover negative trade-offs, i.e. the shifting of environmental burdens from one stage of the life cycle to another.
