News – AU – Australia recorded six months worth of emissions more than before

The revised emissions data reflect a better understanding of the role that highly potent methane gas plays in global warming

The Australian government has recognized that it previously underestimated the country’s greenhouse gas emissions and increased the official estimate for each year recorded

Revised data in the last quarterly emissions update show that Australia pumped out the equivalent of 272 million between 2000 and 2020 t more heat scavenger than suggested in the last report three months ago

It adds about six months’ worth of emissions to the national accounts and increases emissions by 2 average of 3% per year. The full increase is likely to be greater since the report does not include data for before 2000

As Guardian Australia reported last year, the change reflects the approval of scientists that methane – a highly potent but short-lived gas that is released during gas extraction and processing – is playing a bigger role in warming the planet than before accepted

Green leader Adam Bandt said he had shown that the use of gas “cooks the planet”

“When real methane pollution is factored in, it is clear that liberal and worker-backed Narrabri and Beetaloo gas developments [in New South Wales and the Northern Territory] must be halted immediately,” he said

Annually, the report finds that national emissions fell 44% in the year through September 2020, reflecting both the continued surge in solar and wind power and the impact of Covid-19 restrictions

Emissions from power generation decreased 4% during this period, continuing a trend that began before the pandemic broke out

Falls in other parts of the economy have been rather cumbersome and will more likely be undone by emissions increases in the coming year

Transport emissions decreased by 10, 2% of the fugitive emissions from fossil fuel extraction decreased 73% and agricultural emissions decreased 25%

The first two were hit by the pandemic Agricultural emissions continued to be affected by the long-term drought, which forced farmers to significantly cut livestock and the amount of fertilizer used for crops

An independent analysis by energy expert Hugh Saddler found that much of the recent emissions cut would likely be reversed as Covid restrictions were eased and agriculture restored, he said it was because there was no meaningful national policy to reduce it pollution from traffic or agriculture give

Emissions Reduction Minister Angus Taylor said emissions are at their lowest level since 1995, confirming the data reflect both long-term structural change and temporary declines

He said traffic emissions had increased again in the last measured quarter (up to September last year)

The minister said national emissions affected by Covid were now 19% below 2005 levels and the government was on track to meet and exceed its Paris Agreement commitment – a 26-28 cut % by 2030

This contradicts the official projections published in December that the measures currently measurable would result in a 22% cut between 2005 and 2030

Tim Baxter, a senior climate council researcher, said the government could not get “no credit” for the emissions reductions shown in the latest data as it was powered by the pandemic and government-backed wind and solar projects became

“Every state and territory has a net zero emissions target and is committed to clean, affordable renewable energy,” he said. “The federal government should support this change instead of spending billions of public dollars on polluting, unnecessary gas projects”

The Morrison government is under international pressure to do more during this period, in line with the latest climate science and the goals of the Paris Agreement

Britain and the European Union have set a target of 68% and 55% reductions from 1990 levels by 2030 and 55%, respectively. New US President Joe Biden has promised to set a target for 2030 before a summit of states in late April – and heads of government on the topic of climate China is also expected to say more about its plans beforehand

Scott Morrison has announced that it will not lift the Australian target for 2030, which is well below what experts believe is necessary for the country to do its part to solve the problem

The general increase in official Australian emissions data follows the realization that methane has a “warming potential” 28 times higher than CO2, compared to an earlier estimate of 25 times The change is important because the methane emissions in it “CO2 -Equivalent ”before being included in national emissions

Baxter said this still understood the problem. A 2014 report from the Intergovernmental Panel on Climate Change found that the warming power of methane from fossil fuels is actually 30 times greater than that of CO2 The warming power of “biogenic methane” that is released from living organisms such as cows was 28 times higher

A later reassessment published in 2016 in the journal Geophysical Research Letters found it to be even bigger: 34 times higher than CO2 for “fossil methane” and 32 times higher for biogenic methane, Baxter said even this Figures are still not really representative as they do not take into account the feedback effects of greenhouse gas emissions

One of the ramifications for Australia, recognizing that it previously underestimated its emissions, is that it is increasing how much the country can put into the atmosphere while it meets its climate target

Previously, the data indicated that the country has emitted 6155 million t in 2005, the year the cuts are measured. Under the revised data, that has now jumped to 630 million Tons

Because the 2030 target is relative, it also increases the amount that can be spent to meet the target

For example, Australia would have reached 455 million three months ago on a 26% cut t in 2030

Now the land can release 4663 million Tons this year and still claiming to hit their target, despite adding more to the problem
