Melissa King, chief executive of the Organising Committee, has announced that a post-event assessment found the World Cup created unavoidable emissions of 14,062 tonnes of CO2 equivalent.

The Organising Committee said it has purchased the equivalent offsets through "verified and impactful carbon offsets projects" to deliver a carbon-neutral event and create what it dubs a Sustainable Event Blueprint.

"We could not have achieved this without the contributions from ticket-buyers, the International Federation [FIBA], Australian Government, participating team delegations, our staff and volunteers," King said.

Sports Minister Anika Wells added: "The Australian Government proudly supported the FIBA Women's Basketball World Cup, which exceeded expectations.

"Being a carbon-neutral event is an outstanding achievement and the development of the Sustainable Event Blueprint will be an important legacy for future events during the Green and Gold Decade."

The sustainability programme had three focus areas - reducing environmental impacts, sourcing responsibly and inspiring and educating.

Each of these areas achieved positive results.

Ninety per cent of attendees used the train thanks to free travel provided by the New South Wales Government as part of the ticket purchase, while 12 tonnes of material was recovered from the total waste generated during the event and sent for recycling, upcycling or composting.

Event branding suppliers Twenty3 and Evans Evans included a post-event disposal solution as part of their proposal resulting in fabric banners being re-purposed in the making of new mattresses, and corflute returned to the supplier to be converted back into beads for use in new products.

More difficult items to recycle such as lanyards were recycled through Terracycle, an innovative recycling organisation offering solutions for hard-to-recycle materials.

Oganisers also report 95 per cent of food packaging was certified compostable and could be placed in the organic bin for composting.

"The Sustainable Event Blueprint, developed in collaboration with MI Global Partners, is complete and a key component of legacy for sport and future events," said Stephanie Lebeau, the Organising Committee's sustainability manager.

"It is a comprehensive piece of work providing guidance on factors for consideration when thinking about event sustainability.

"The Report and Quick Guide will be made available on the Federal Office for Sport Website, hoping they will serve as a source of knowledge and inspiration."
