The Rio Open, presented by Claro, is committed to reducing the environmental impact of the Tour.

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

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

“The figures prove that it is possible to organize a major sporting event with an increasingly lower impact on the environment and at the same time generate significant economic results for the city and the community,” said Marcia Casz, general manager of the Rio Open, presented by Claro.

The Rio Open Green program 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 activities and fan travel. All emissions are offset by UN-certified carbon credits generated by the production of renewable energy at the Jirau hydroelectric power plant.

With approximately 40 percent of fans traveling to the Rio Open from other states, the focus is on helping fans understand their carbon footprint. An interactive carbon calculator is part of the ticket purchasing process, allowing fans to specify their mode of transport, understand the impact of their trips and even choose low-impact travel options such as cycling or public transport.

By 2025, only 30.8 percent of waste generated by the event was sent to landfills, thanks to Rio Green Project’s waste management strategy. A number of initiatives have been taken, with a focus on reuse and recycling, reducing single-use plastics and supporting responsible disposal.

The Rio Open presented by Claro is a great 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 recognizes its unique platform and responsibility to lead the way in sustainability.
