"We know, despite what you tell your investors, that there is strong evidence that your toxic waste damages the environment and that accidents/spills are common," she said. Loading "We know that you have no solution to dispose safely of your waste products. "We demand you be truthful about your own emissions and that you find solutions immediately to reduce your carbon and methane footprint.

"We demand a just transition for workers to provide them ethical employment that doesn't damage the planet." Protesters chanted while holding placards outside the building before falling to the ground. Some activists then stood in the middle of the street multiple times and were forced off the road by police. Brisbane water engineer Dr Anne Gardiner said the practice of coal seam gas mining that had boomed in the last 15 years had to stop. "Santos claim they can capture most of the fugitive methane emissions from their CSG operations – but experts tell us that this is not the case," she said.

"Methane is a super polluter, up to 86 times more potent than CO2." Loading Dr Gardiner said Santos was not mitigating the effects of methane. "Santos knows full well that they can’t capture all the emissions that they're flaring, that they’re undertaking is just burning off methane from the pumping and compression stations," she said. "It’s not dealing with the ethane that is seeping out of the ground everywhere we go.

"Santos knows that they’re pulling up water latent with organic waste and latent with salt and they’re dumping it back in river systems. "Santos knows that what they’re doing is draining away surface creeks and putting the water into major river systems, polluted water." However, a Santos spokeswoman said the company respected the right of people to protest peacefully. More than 100 activists were protesting outside of the Santos building on Tuesday.

"The International Energy Agency’s 2018 World Energy Outlook Sustainable Development Scenario recognises this can only happen with growth in natural gas demand and investment in more supply out to 2040." The spokeswoman said Santos had been working to develop Australia's natural gas, which was "a fuel for the future providing cleaner energy to improve the lives of people in Australia and Asia". "Asia accounts for half of the world’s 50 billion tonnes of annual greenhouse gas emissions so increasing LNG sales to Asia is where we can have the biggest global impact on emissions reduction," she said. "For every tonne of carbon dioxide emitted during production in Australia, our LNG saves between 3 and 10 tonnes of emissions when it is used for power generation, instead of coal, in Asia."

She said Santos would continue to develop natural gas as a "vital climate solution". About three hours later, a man climbed onto the King George Square bus station for half an hour before he was arrested. Earlier on Tuesday, one man was dangling from the Story Bridge for about four hours in support of the movement while police and firefighters worked to cut three protesters from a barrel and a wooden construction stuck to the road in Brisbane's CBD. Extinction Rebellion, which is demanding 100 per cent renewable energy, giving nature legal rights and the sharing of science, will hold protests every day in the city this week. Queensland police said 29 people between the ages of 19 and 75 were arrested on Tuesday.
