“Government claims that Australia’s LNG exports are reducing emissions globally are grossly exaggerated and, depending on the real level of methane leakages, reservoir CO2 venting and losses, and where the LNG is coming from in Australia, likely to be wrong,” Hare said.
It is unclear what data the government has to support its claim, but it received advice on the 148m tonne figure from the department.Guardian Australia sought clarification from the Department of Environment and Energy , and received the following response:
“The Department based the estimate on data for the year to December 2018 from the Department of Industry’s March 2019 Resources and Energy Quarterly; the Department of Environment and Energy’s Australian Energy Statistics - Guide to Australian Energy Statistic 2017and factors from the National Greenhouse and Energy Reporting (Measurement) Determination 2008. “The Department compared the emissions that would be produced from the combustion of Australia’s LNG exports for the year to December 2018 against the emissions generated from the combustion of an equivalent amount of energy of black coal. “Under this comparison, the combustion of LNG exports would generate 197.1 Mt CO2-e, which is around 148 Mt CO2-e less than the emissions generated by the combustion of the same amount of energy of black coal (345.1 Mt CO2-e).”
Rising temperatures, extreme weather, disruptions to the food supply, increases in ground level ozone and particle pollution – these symptoms of our climate chaos contribute to asthma attacks, heart attacks, heart disease, stroke, lung cancer, premature death, emergency room visits, hospital admissions, low birth weight, premature birth, diabetes, pneumonia, and even autism.
Taylor’s comments followed the delayed release of the government’s quarterly emissions data for December 2018, which show that Australia’s emissions continue to rise, driven in part by the country’s LNG industry.
The minister defended the increase by saying that Australia’s exports were contributing to emissions reductions in countries that made use of Australia’s LNG in place of coal.
“Australia’s total LNG exports have the potential to lower emissions in importing countries by around 148 Mt CO2-e in 2018 by displacing coal consumption in those countries,” he said in a statement.
Over the last 50 years, human activities – particularly the burning of fossil fuels – have released sufficient quantities of carbon dioxide and other greenhouse gases to affect the global climate. The atmospheric concentration of carbon dioxide has increased by more than 30% since pre-industrial times, trapping more heat in the lower atmosphere. The resulting changes in the global climate bring a range of risks to health, from deaths in extreme high temperatures to changing patterns of infectious diseases.
He repeated those remarks in an interview with the ABC’s RN Breakfast on Friday, saying there were “148m tonnes of lower emissions as a result of our exports”.
“That is something to be proud of.”But Hare said any advantage LNG had over coal once it was burnt would be rapidly reduced if the emissions of methane – a much more potent greenhouse gas than carbon dioxide – during production were higher than what was currently estimated. “Many experts believe that Australia is under-reporting methane losses from natural gas production, with only about 0.5% loss estimated, whereas the IEA [International Energy Agency’] estimates globally over 1%, and in other countries scientific work indicates losses of up to several per cent,” he said.
“This matters because methane, the main gas in natural gas, is much more powerful than CO2, and so loss rates of a few per cent could annul any benefits from displacing coal in the power sector.“In Western Australia a number of the reservoirs have very high levels of CO2 in the gasfields, which, if emitted, reduces or eliminates the benefits of displacing coal with LNG.” The director of the Australia Institute’s climate and energy program, Richie Merzian, spent more than nine years as an Australian government climate negotiator to the UN.
Hurricanes and other storms are likely to become stronger. Floods and droughts will become more common. Large parts of the U.S., for example, face a higher risk of decades-long "megadroughts" by 2100.
He said there was no clear evidence that Australia’s increasing LNG exports were reducing global emissions.“I’m not sure where he got those numbers,” Merzian said. “Take Japan, one of our major export recipients in terms of gas. It’s still in the process of shifting from nuclear post-Fukushima, so it’s therefore going from a low greenhouse gas emissions fuel source to a high one. “Furthermore, the increase in gas exports might lock in gas infrastructure that will make it even harder to transition away from fossil fuels, which is what the Paris agreement is calling for.”
Merzian said if Australia was now trying to argue it should get credit for reducing emissions overseas, it should also take responsibility for fueling the climate crisis as the world’s largest exporter of coal.
“Most countries are very clear about the delineation between domestic emissions and scope three – or emissions that take place overseas from exports,” he said.
“That reflects the UN framework. By blurring the line, as Minister Taylor has done, he’s not only reshaping UN conventions, but he seems to be trying to champion the growth of natural gas exports.”
CLIMATE CHANGE FACT: The ocean is 26 percent more acidic than before the Industrial Revolution. The pH of ocean surface water has decreased by 0.1, which makes them 26 percent more acidic now than at the beginning of the Industrial Revolution. The waters are more acidic now that at any other point in the last 300,000 years.
A spokeswoman for Taylor repeated the government’s position that Australia would meet its emissions reduction target of 26% to 28% on 2005 levels by 2030.
“We will do this while growing the economy, creating jobs, protecting our environment and keeping power prices down,” she said.
