Earth Hour 2021

Earth Hour is organised by the WWF and was first held in Sydney, Australia in 2007, where individuals turned their lights off for one hour. Now millions of people worldwide take part in the global annual event which raises awareness of how our actions affect the planet.

To ensure the greatest visual impact for the global lights out event, Earth Hour is held annually in March. This is because it is around the time of the Spring and Autumn equinoxes in the northern and southern hemispheres respectively, which allows for near coincidental sunset times in both hemispheres. The objective is to raise awareness by asking people to switch off any unnecessary lights, plugs and sockets for the duration of the event. The ultimate aim is for people to take action beyond the hour, raising awareness and taking action all year round.

This year, Green Park partnered with occupier, Bayer, to turn off as much of the main building lighting as possible, with the exception of the emergency lighting, for the duration of Earth Hour on Saturday 27th March. We also turned off the lighting to the Green Park masts as a visual display of our commitment to our environment. To demonstrate our participation, we were able to capture the event in a time-lapse video and in photos.
