Environmental awareness and sustainable practices in the apparel industry continue to be at the forefront of conversation, with many companies investing in these areas. That’s exactly what adidas did with a floating tennis court and new apparel line, but the company didn’t do it alone.

The brand recently teamed up with environmental organization Parley for the Oceans to create a recycled-plastic tennis court that floats within Australia’s Great Barrier Reef marine park. The launch coincided with the Australian Open tennis tournament that took place in Melbourne from Jan. 9-30. The floating court was created to promote adidas’ latest range of apparel, which incorporates recycled plastic.

The range of clothing is the recent collaboration between the brands, whose previously launched collection Adidas x Parley features high-end sportswear that uses Parley Ocean Plastic as a replacement for virgin plastic. The new collection builds on adidas’ initiative to remove plastics from its apparel.

The apparel debuted on the floating tennis court, which was placed in the Great Barrier Reef to draw attention to the wider issue of plastic waste. Before you worry too much about the environmental impact, note that adidas worked with the Great Barrier Reef Marine Park Authority to assemble the floating tennis court on one of the marine authority’s barges.

“The new adidas tennis apparel collection, that [was] worn by players during the Australian Open in Melbourne, has been inspired by the beauty of the Great Barrier Reef and consists of products from one of our sustainability innovators, Made with Parley Ocean Plastic,” an Adidas spokesperson said in the press release.

To mark the launch, swimmer Ian Thorpe, canoeist Jess Fox, and rugby league player Nathan Cleary, along with model Steph Claire Smith, played a game of mixed doubles on the court, where adidas again demonstrated its environmental awareness by stating that all tennis balls were retrieved from the ocean.

“We’re committed to help end plastic waste and, by 2024, we’ll replace virgin polyester in our products with recycled polyester wherever possible,” said Shannon Morgan, Pacific senior director of brand at adidas. “To achieve these goals, we foster open-source partnerships and put a high value on collaboration over competition to create sustainable solutions that go beyond our own business and influence.”
