The UAE joined countries all over the world in marking Earth Hour on Saturday evening by switching off thousands of lights.
Between 8.30pm and 9.30pm, thousands of homes, businesses and government departments switched off their lights to raise awareness of the planet's environmental degradation.
The Roads and Transport Authority, RTA switched off 1,433 street lights across the UAE, while landmarks across the Emirates went dark for one hour.
In Abu Dhabi, the Sheikh Zayed Grand Mosque was one of the major land marks that turned its lights off, while in Dubai, the Burj Khalifa, the world's tallest building was also plunged into darkness.
Emirates Global Aluminium said it had saved over 70,000 kilowatt hours of electricity in the past year through weekly observance of Earth Hour.
Carrefour UAE also participated by switching off 50 per cent of light in its 28 stores nationwide.

Speaking before the switch-off, Laila Mostafa Abdullatif, director-general of EWS-WWF said this year's Earth Hour was especially important due to it coinciding with the Year of Sheikh Zayed. “Earth Hour highlights the power of each individual, and what we can achieve if we do it together. With 2018 being the Year of Sheikh Zayed, we invite everyone to join the movement, honour our Founding Father’s vision, and help us make a difference. The late Sheikh Zayed bin Sultan Al Nahyan was a visionary in terms of sustainable development. He understood the power of the human spirit and united our nation”.
