Product Carbon Footprint (PCF)
There are three main Product Carbon Footprint standards that are or will be applied worldwide: PAS 2050, GHG Protocol and ISO 14067.PAS 2050 has been developed by the British Standards (BSI) and came into effect in October 2008. PAS 2050 has already been applied by many companies worldwide and was revised in 2011.
The GHG Protocol product standard was developed by the WRI/WBCSD and launched after testing by 60 companies in 2010.
ISO/TS 14067 is released in 2013.
All three standards provide requirements and guidelines on the decisions to be made when conducting a carbon footprint study. Decisions involve LCA issues, like goal and scope definition, data collection strategies, and reporting. Moreover, these standards provide requirements on specific issues relevant for carbon footprints, including land-use change, carbon uptake, biogenic carbon emissions, soil carbon change, and green electricity.
All three standards build on existing life cycle assessment methods established through ISO 14040 and ISO 14044.
