Morrison Government continues to drag its feet on national greenhouse gas emissions reduction


Renew Economy, 21 September 2020:

Morrison said, of net zero emissions:

"Well, as you know, our policy is to achieve that in the second half of this century, and I certainly will achieve that, and that’s why this week’s announcements were so important because it was about the technology we need to invest in now, which will make it a reality, particularly on the other side of 2030. The target that you’ve talked about becomes absolutely achievable. I’m interested in doing the things that make that happen. I think that is very achievable"…..

Morrison was, in fact, effectively stating that Australia would reach net zero emissions by 2100. Heck, what’s a half-century between friends?

In fact, Australia’s Paris climate agreement targets are neatly aligned with reaching net zero by 2100, whereas Labor’s old 45% by 2030 targets were aligned with net zero by 2050 (the far safer option). Unfortunately, the latest projections from the government are wildly off course, not only for net zero by 2050, but also for net zero by 2100….

If the rate of yearly emissions drops between 2020 and 2030 in Australia’s government projections continue, by my own reckoning, Australia will reach net zero emissions in the year 2300….

The Guardian, 22 September 2020:

The Morrison government’s rejection of a net zero emissions target for 2050 is at odds with the Paris agreement and more than 100 countries that have backed the goal, according to some of Australia’s most experienced climate experts..... 

countries in Paris including Australia had specifically asked the Intergovernmental Panel on Climate Change to examine what 1.5C of heating would mean, and what needed to be done to avoid it. 

The resulting report, released in 2018, found global emissions needed to effectively be cut in half by 2030 – to be 45% below 2010 levels – and to reach net zero by 2050. It found staying within 2C heating would require net zero by 2070, but the impact of that was likely to be far worse

Australia chose to stick with its existing 2030 target of a 26% to 28% cut below 2005 levels and is yet to set a date to reach net zero.....

By contrast, [Erwin] Jackson said, Australia was “confusing the market”. “On the one hand, it has signed up to an international agreement that is supposed to put it on a path to net zero emissions by no later than 2050,” he said. “On the other, it keeps talking about ‘low emissions’. We’ve moved on from a conversation about low emissions. Globally, we have recognised we need to get to zero emissions.”

BACKGROUND

Australia is almost standing still when it comes to reducing its national annual greenhouse gas emissions. At the end of 19 calendar years in 2019 federal government policy has only resulted in our annual greenhouse gas emissions falling by a trifling 18.5 metric tonnes in comparison with the annual emissions at the end of the year 2000.

Estimated National Greenhouse Gas Emissions in metric tons of carbon dioxide equivalent or MTCO2e over last 20 years - includes Land Use, Land Use Change and Forestry:

2000 - 551 Mt CO2-e
2001 - 570 Mt CO2-e
2002 - 568 Mt CO2-e
2003 - 561 Mt CO2-e
2004 - 574 Mt CO2-e
2005 - 597 Mt CO2-e 
2006 - 610 Mt CO2-e
2007 - 606 Mt CO2-e
2008 - 590 Mt CO2-e 
2009 - 584 Mt CO2-e 
2010 - 543 Mt CO2-e
2011 - 546.3 Mt CO2-e
2012 - 551.9 Mt CO2-e (total excludes Land Use, Land Use Change and Forestry)
2013 - 538.4Mt CO2-e
2014 - 535.9 Mt CO2-e 
2015 - 535.7 Mt CO2-e
2016 – 543.3 Mt CO2-e
2017 – 533.7 Mt CO2-e
2018 – 532.5 Mt CO2-e 
2019 – 532.5 Mt CO2-e (this annual total marks a difference of only -18.5 Mt CO2-e compared with the year 2000 annual total)
2020 – 528.7 Mt CO2-e (total up to 30 March)

New report by the World Meteorological Organization warns global warming 1.5℃ limit may be exceeded by 2024—and the risk is growing.


Phys Org, 9 September 2020:



The Paris climate agreement seeks to limit global warming to 1.5℃ this century. A new report by the World Meteorological Organization warns this limit may be exceeded by 2024—and the risk is growing.

This first overshoot beyond 1.5℃ would be temporary, likely aided by a major climate anomaly such as an El Niño weather pattern. However, it casts new doubt on whether Earth's climate can be permanently stabilized at 1.5℃ warming.

This finding is among those just published in a report titled United in Science. We contributed to the report, which was prepared by six leading science agencies, including the Global Carbon Project.

The report also found while greenhouse gas emissions declined slightly in 2020 due to the COVID-19 pandemic, they remained very high—which meant atmospheric carbon dioxide concentrations have continued to rise…..
