Preparing for a climate positive 2032 Olympics

According to University of Queensland researchers, a requirement for the 2032 Brisbane Olympic and Paralympic Games is to be climate positive, representing an opportunity for the state to be bold and leave the city with a valuable legacy.

Dr Tony Heynen and Prabhakaran Vanaraja Ambeth from the School of Chemical Engineering have assessed different combinations of measures to help Brisbane meet its climate positive contractual obligation to the International Olympic Committee.

“It is an exciting time and while international eyes will be on us, we can harness the momentum of the Games and grasp this climate commitment as an opportunity,” Heynen said.

The two main levers that can be used for climate positivity are emissions reduction and carbon offsets.

Using ecological, social and economic criteria, the researchers assessed three different combinations of the levers for Brisbane.

“The higher the reliance on carbon offsets, the poorer the sustainability outcome for the Games, even if the offsets are massive tree plantations in Queensland.

“While the most sustainable scenario of investment in things like mass transport systems and renewable energy to cut emissions is expensive, they will leave greater benefits for future generations,” Heynen said.

The methodology developed by the researchers to assess and track the planning and delivery of a climate positive mega-event can be adapted for other places and events in the future.

“Paris is doing some really innovative and ambitious things around sustainability for this year’s Summer Olympics.

“Los Angeles will learn from and build on that experience for 2028 but Brisbane is the first city to have the climate positive requirement written into its host contract.

“Brisbane will have to deliver the event under the International Olympic Committee’s new norm focus on sustainability,” Heynen said.

The Olympics also needs to fit the region and deliver legacy benefits, beyond new stadiums. According to Heynen, to do this, the private sector should be more engaged and community awareness of the commitment and benefits it can offer should be boosted.
