The International Organization for Standardization (ISO) is working on a new standard for “Carbon Footprints of Products” for the quantification and communication of GHG emissions associated with goods and services. The standard builds largely on the existing ISO standards for life cycle assessments (ISO 14040/44) and environmental labels and declarations (ISO 14025) and is planned to be published by March 2011. In comparison to the existing LCA standards it contains further provisions for the uniform quantification of GHG emissions. The standard is currently converted into Committee Draft status, implying that the main provisions have been set and commenting is now taking place on a per country basis.
