Over 7,000 towns and cities in 154 countries are coming together with one mission; to use power to make change a reality.
On Saturday March 29th at 8.30pm, millions of people across the world are switching off lights for one hour - to celebrate their commitment to the planet.
An initiative that started as an hour has turned into a global movement. In Uganda, half a million trees have been planted in the world's first Earth Hour Forest in a fight against the 6000 hectares of deforestation.
In Russia, 120,000 people protested to protect the country's seas from oil pollution. They all signed a petition which led to a new law being passed defining rules for extracting and transporting hydrocarbons and requires operating companies to take increased responsibility for preventing oil spills. This action was endorsed by many celebrities who pledged to complete challenges to support the cause.
In addition, the seas in Argentina have also received protection after the levels of sea under protection was raised from 1% to 4%,meaning that today 3.4 million hectares of sea is being protected in Argentina alone.
What once started off in Sydney is 2007, it is now a global event with many cities, individuals and companies getting in involved and The Cavendish London was no exception. Last year the 4 star deluxe hotel on Jermyn Street,renowned for its customer service switched off its lights throughout the property. LED lights were replaced with lanterns in the lobby; candles were lit for diners in Petrichor restaurant as well as the turning off of non-vital appliances such as fridges. For one hour, what is usually a bright welcoming area was turned into a dark space that you would normally find in a Harry Potter Movie.
After a successful 2013, the environmentally friendly and sustainable hotel in Mayfair is doing it again.
