ATP Serves: How the Rio Open presented by Claro drives carbon-neutral tennis

Read how the ATP 500 event has fully offset its emissions since 2020

February 21, 2026

The Rio Open presented by Claro is going above and beyond to reduce its environmental impact on Tour.

Through the ATP 500 tournament’s environmental programme, Rio Open Green, the event achieved landmark results in 2025 and has continued to reduce emissions while also engaging in fan awareness.

Last season, the event neutralised 1,819 tonnes of CO2 equivalent (tCO2e), with 69.2 per cent of waste recycled, reused or composted. The clay-court tournament has set an example as a United Nations-certified carbon-neutral event, having fully offset its emissions since 2020.

“The figures prove that it is possible to host a major sporting event with an increasingly lower environmental impact while simultaneously generating significant economic results for the city and the community,” said Marcia Casz, General Director of the Rio Open presented by Claro.

The Rio Open Green programme is centered around three pillars: Reducing emissions, fan awareness and waste management.

In partnership with ENGIE, the tournament calculates and offsets greenhouse gas emissions associated with both event operations and fan travel. All emissions are offset through UN-certified carbon credits generated from renewable energy production at the Jirau Hydroelectric Power Plant.

With around 40 per cent of fans travelling to the Rio Open from other states, there is an emphasis on helping fans understand their carbon footprint. An interactive carbon calculator is part of the ticket purchase process, enabling fans to specify their mode of transport, understand the impact of their travel and even opt for low-impact travel options like cycling or public transport.

In 2025, only 30.8 per cent of waste generated from the event was sent to landfill sites, thanks to Rio Green Project’s waste management strategy. A number of initiatives have been put in place, with a focus on reusing and recycling, reducing single-use plastics and supporting responsible disposal.

The Rio Open presented by Claro is a prime example of tournaments, players and partners uniting through ATP Serves. As a global sport spanning more than 60 tournaments in nearly 30 countries, the ATP recognises its unique platform and responsibility to lead on sustainability.
