BS 8901 is the British Standard which has been developed specifically for the events industry. It defines the requirements for a sustainability event management system. It is the precursor and model on which ISO 20121 is based. Once ISO 20121 is launched globally, it is anticipated that the BS8901 will be upgraded to mirror the ISO 20121. In Australia, if the ISO 20121 is accepted, an identical Australian Standard will be established and therefore events in Australia complying with the standard will be achieving both Australian Standards and ISO compliance.
