Australians signing up to Earth Hour 2019 this weekend are demanding that federal politicians act now to ensure their country gets back on track to meet its international climate change commitments, with 170,000 messages of support already sent to key parliamentarians.


This demand is strongly aligned with the release of the Global Climate Report by the United Nations yesterday as ‘another strong wake-up call’ to step up the urgency of action on climate change.


The government’s own data shows that Australia is on track to reduce greenhouse gas emissions by only 7%, despite making an international commitment to reduce emissions by 26-28% on 2005 levels by 2030.


This year, every Earth Hour sign-up by a member of the public triggers a message that is sent to key federal politicians that calls for Australia to get back on track to meet our 2005 Paris Agreement commitment. Australians are expected to send about 250,000 messages to parliamentarians.


“Australians will send a powerful message to politicians demanding urgent action on climate change because they are deeply concerned about its impact on the environment, food production and our way of life,” said WWF-Australia CEO, Dermot O’Gorman.


On Earth Hour, Australians will call for urgent action to halt biodiversity loss, which is being intensified  by climate change. Globally, species have declined by 13% per decade since 1970. In Australia, the situation is worse with iconic species such as the koala declining by 21% per decade.


“The future for koalas, the Great Barrier Reef and the Murray Darling River system is bleak unless we take steps today to address the effects of climate change, which is already having a huge impact on our beloved animals and landscapes” said Mr O’Gorman.


Businesses are also signing up to Earth Hour to demonstrate their growing commitment to supporting stronger action to prevent climate change. Some of Australia’s largest businesses including Atlassian, Coca-Cola South Pacific, and Solotel have already signed up to Earth Hour 2019.


More than a quarter of a million school children are switching off their lights today for Earth Hour Schools Day.  


“Earth Hour is now observed in over 180 countries and territories, and shown how the individual actions of millions of people can collectively make a big difference to better care for our planet,” said Mr O’Gorman.


Earth Hour is on Saturday 30 March, 8.30 pm local time. Households, businesses and iconic Australian landmarks such as the Sydney Opera House and Sydney Harbour Bridge will turn off their lights for one hour during the event.
