Australia and the world are fast running out of time to limit negative impacts of climate change to spans of multiple generations rather than millennia

 

The United Nations website is very clear about what has been agreed at an international level concerning the global response required to limit the Earth’s global warming to an average 1.5°C, thereby limiting the negative impacts of climate change in intensity and time span – hopefully to spans of multiple generations rather than millennia.

The Paris Agreement is a legally binding international treaty on climate change. It was adopted by 196 Parties at the UN Climate Change Conference (COP21) in Paris, France, on 12 December 2015. It entered into force on 4 November 2016.

Its overarching goal is to hold “the increase in the global average temperature to well below 2°C above pre-industrial levels” and pursue efforts “to limit the temperature increase to 1.5°C above pre-industrial levels.”

Australia is a party to the 2015 Paris Agreement, effective 4 November 2016.

However, in recent years, world leaders have stressed the need to limit global warming to 1.5°C by the end of this century.

That’s because the UN’s Intergovernmental Panel on Climate Change indicates that crossing the 1.5°C threshold risks unleashing far more severe climate change impacts, including more frequent and severe droughts, heatwaves and rainfall.

To limit global warming to 1.5°C, greenhouse gas emissions must peak before 2025 at the latest and decline 43% by 2030.

All those nations which entered into the Paris Agreement agreed to participate in the global attempt to reduce the world’s greenhouse gas emission by establishing firm undertakings in Nationally Determined Contributions (NDCs).

In their NDCs, countries communicate actions they will take to reduce their greenhouse gas emissions in order to reach the goals of the Paris Agreement. Countries also communicate in their NDCs actions they will take to build resilience to adapt to the impacts of climate change.

Australia submitted its first NDC to the United Nations Framework Convention on Climate Change (UNFCC) in 2015 and updated that version of the NDC in 2022. This update commits Australia to reducing its emissions to 43% below 2005 levels by 2030. It should be noted that in 2005 Australia’s total national greenhouse gas emissions of 559.1 million tonnes of carbon equivalent gases (MT CO²-e) was already 102.2% of its 1990 annual total of 515.9 MT CO²-e.

It could be said that even now our national reduction of greenhouse gas emissions is sluggish at best.

"For the year to June [2023], according to the preliminary numbers from the government’s latest national greenhouse gas inventory, emissions were 4.1 million tonnes above those for the corresponding period the previous year." [The Saturday Paper, 08.09.23]

 

In the year to December 2015 Australia’s “annual unadjusted” greenhouse gas emissions stood at 529.2 MT CO²-e. An artificially constructed figure because per government policy it excluded emissions from from land use, land use change and forestry. These excluded emissions would have possibly added more than 1.0 MT CO²-e bringing the national annual total to over 30 MT CO²-e in 2015.

By year to December 2022 Australia’s “actual annual” greenhouse gas emissions were recorded as 463.9 MT CO²-e. A figure arrived at by an alleged fall in emissions from land use, land use change and forestry of est. -13.6 MT CO²-e due to professed reductions in land clearing and native forest harvesting, increases in plantations and native vegetation, and improvements in soil carbon. NOTE: By year to December 2022 each person in Australia was estimated to be responsible for 17.8 tonnes CO²-e of that year’s greenhouse gas emissions total.

What Australian governments and industries has effected was a paltry national greenhouse gas emissions change of est.

-65.3 MT CO²-e spread over eight years – an average of 8.1. Or est. -95.2 MT CO²-e spread over 17 years – an average of 5.6 MT CO²-e per annum. And that change was to a significant degree on the back of the adoption of rooftop renewable energy by the general population which in the year to December 2022 was contributing to an electricity sector emissions reduction of 5.5 MT CO²-e, according to the Dept. of Climate Change, Energy, the Environment and Water.

Either way, leaving Australia with an urgent need to reduce greenhouse gas emissions by at least the promised -240.4 MT CO²-e within the next seven years. That’s roughly 34.3 MT CO²-e emissions we have to cease releasing into the air, waterways and oceans each and every year until 2030 to even have a chance at surviving as a nation and a functioning society beyond that year.

Creative accounting using offsets, hiding behind green washing propaganda, pushing hard decisions further down the track into the future, just won’t work. We need to immediately tighten polluting emissions regulations & abatement requirements, begin phasing out current unabated fossils greenhouse gas and, from this point in time where we stand right now, we must refuse all new or expanded proposals for fossil fuel extraction and use.

Australian industry and corporations both foreign and domestic are laughing in our faces and, federal & state governments appear all but frozen into inaction by the magnitude of the climate crisis before us. There will be no heroes coming down from the mountains to save us, no ships arriving to sail us all to as yet undiscovered safety, no divine miracles falling from the skies.

Australia’s estimated resident population stood at 26,268,359 men, women and children in December 2022 according to the Australian Bureau of Statistics. 

An estimated 21,461,249 of the resident population in 2022 were individuals 15 years of age and older.

By default theirs is the burden of stopping that 240.4 MT CO²-e of additional pollution entering earth’s atmosphere over Australia by 2030. That’s an extra 11.2 tonnes CO²-e per person averaging 1.6 tonne of carbon equivalent a year.

So how do we each attempt to shoulder this terrible burden? 

"Key finding 4: global emissions are not in line with modelled global mitigation pathways consistent with the temperature goal of the Paris Agreement, and there is a rapidly narrowing window to raise ambition and implement existing commitments in order to limit warming to 1.5 °C above pre-industrial levels."

Postscript:

Stocktaking our personal emissions level and, looking at ways of reducing that average per head of population average green house gas emission excessive budget of 17.8 tonnes CO²-e, may be something we can all attempt. 

For example: 

• the average vehicle in Australia is estimated to travel 12,100 km per year or 33.2 km per day, which represents around 2.1 tonne CO²-e annually; 

• while the average household across all power supply types is estimated to consume 5,818.6kw/h of electricity each year, which can be as high as 3 tonne CO²-e annually depending on the mix of supply types per household; and

• imported food or imported ingredients have food transport kilometres attached, which in Australia's case means food importation from the European Union represents est. 1.3 MT CO²-e annually or approx. 50 kg CO²-e per capita. A serve of deli sausage from Denmark travels est. 25,000 food kilometres to reach the supermarket counter. 

Time to get cracking and shame the devils who brought us to this catastrophic pass - even if the task appears impossible and we merely so many cursed children of a condemned Sisyphus.
