From London to Singapore and Sydney, cities around the world dim their lights to mark Earth Hour
- Asia had kicked off the event after night fell with the skylines of metropolises from Singapore to Hong Kong going dark, as did landmarks including the Sydney Opera House
- In Paris, the three stages of the Eiffel Tour progressively went dark but there were few people to watch, with the whole country under a 7pm Covid-19 curfew

Cities around the world were turning off their lights on Saturday for Earth Hour, with this year’s event highlighting the link between the destruction of nature and increasing outbreaks of diseases such as Covid-19.
In London, the Houses of Parliament, London Eye Ferris wheel, Shard skyscraper and neon signs of Piccadilly Circus were among the landmarks flicking the switches.
“It’s fantastic news that parliament once again is taking part in Earth Hour, joining landmarks across the country and the world to raise awareness of climate change,” said Lindsay Hoyle, Speaker of the House of Commons.
“It shows our commitment to improving sustainability … and that we’re playing our part in reducing energy consumption,” he said.

In Paris, the three stages of the Eiffel Tour progressively went dark but there were few people to watch with the whole country under a 7pm Covid-19 curfew.
