Zsombor Barta, the head of sustainability and legacy at Budapest 2024, cited the fact that the River Danube will be at the heart of the Games should the city be successful with its bid as a key example of how they can achieve their sustainability aims.

Budapest 2024 claim infrastructure and applications such as "cutting-edge water purification technologies" are "common themes" which run throughout their bid.

They also insist water efficiency "features prominently" in a number of construction projects which would be built if Budapest is chosen as the 2024 Olympics and Paralympics host city.

Budapest 2024 point to a recent survey, which revealed the water quality at Lágymányosi Bay, the proposed venue for the swimming section of the triathlon event, and Maty Stream in Szeged, which would hold canoe sprint competitions, was excellent.

The high quality of drinking water in Budapest has become a main theme of Budapest 2024’s waste and resource management plan, they claim.

Geothermal cooling and heating solutions from the River Danube, the longest river in the European Union region, are also being explored as part of their efforts to secure the hosting rights for the Games.

Bid Committees are often keen to stress the sustainability benefits of their particular candidacy in order to appeal to the International Olympic Committee (IOC) and its President Thomas Bach.

"The Olympic Games in 2024 in Budapest, with the River Danube at its heart, would help us to spread the sustainability message as widely as possible," Barta said.

"We need to encourage bold new ways to innovate the use of our world’s most precious resources."

Budapest recently held the 2016 Water Summit, co-organised by the World Water Council and the United Nations, which gathered scientists and academics, as well as a delegation from the Bid Committee.

The Summit, held under the theme of "Water Connects", took place from November 28 to 30.

"We are in the unique position of being a Central European hub," Barta added.

"Thought leaders from around the world gather here to share their ideas at forums like the Budapest Water Summit, the outputs of which are adopted by the UN Sustainable Development Summit.

"We are extraordinarily lucky to have access to this concentration of expertise which is helping us to formulate inspirational yet practical sustainability plans for the Budapest 2024 Olympic Games bid."

Bid officials revealed earlier this year that athletes competing at the Budapest 2024 Summer Olympics and Paralympics would travel to many events via boats along the River Danube.

Los Angeles and Paris are also bidding for the 2024 Olympics and Paralympics, with Rome’s effort currently suspended.

The IOC will elect its chosen host city at its Session in Lima on September 13.
