Dubai saved 178 megawatts of electricity during Earth Hour, according to the Dubai Electricity and Water Authority (DEWA), equivalent to 74 tonnes of carbon emissions.
Millions around the world switched out unnecessary lights and electrical appliances from 20:30-21:30 to express solidarity with efforts to address climate change.
Landmarks and public buildings around Dubai also switched out their lights to mark the occasion.
"Earth Hour aims to make conservation of electricity and water a daily practice to cut carbon emissions and combat environmental challenges such as climate change, global warming, and the unprecedented reduction in biodiversity," said Saeed Mohammed Al Tayer, Managing Director and CEO of DEWA.
