Qatar has stressed that if it is chosen to host the 2022 FIFA World Cup it will use carbon-neutral technology to cool its stadiums.
Three state-of-the-art stadiums would be built for the event, with two existing arenas due for expansion.
Qatar 2022 chairman Sheikh Mohammed bin Hamad bin Khalifa Al-Thani said: “Our stadiums will have zero carbon cooling equipment utilising solar technology to ensure the temperature is no higher than 27 degrees Celsius, ensuring optimum playing conditions and a comfortable environment for fans.
“What we have unveiled is a world first, and as part of Qatar’s commitment to delivering an historic legacy we will share this groundbreaking technology with the rest of the world.”
FIFA’s executive committee will vote on the location of the 2018 and 2022 World Cups in December this year in Zurich.
