Blended fuel powers 15-hour Boeing Dreamliner 787-9 flight between LA and Melbourne, reducing carbon emissions by 7%

A Qantas plane powered partly by mustard seeds has become the world’s first biofuel flight between Australia and the United States, after landing in Melbourne on Tuesday.

As more media outlets use automated algorithms to write news stories, are journalists doomed?

Help us to move these issues up the public agenda and challenge governments to do more

Australia’s fragile environment is under attack. Environmental protections have been dramatically eroded and funding slashed. The threat to climate change so dominates debate that other pressing and immediate environmental dangers struggle for attention. Few Australians know that our country has one of the worst records for species loss, with even the koala threatened; that microplastic pollution is so prevalent it can be found in the sediments of our river estuaries and nearby ocean floors; or that land clearing rates are just as severe as the notorious deforestation of the Brazilian Amazon.

The nation is losing the political will to protect our pristine places – and biodiversity is suffering

What if the Franklin river hadn’t been saved?

Stopping the Gordon-below-Franklin dam was one of the Australian environment movement’s great victories: in the late 1970s, the state-owned Hydro-Electric Commission wanted to flood one of three last temperate rainforests in the southern hemisphere to create a power station.
