Australia’s net zero targets don’t add up

The Climate Change Authority has warned that Australia must cut emissions by 75% by 2035 to limit global warming to 1.5 degrees.

“We need to seize this once-in-a-generation opportunity to ensure Australia’s rapid and orderly transition as the world transforms to avert the worst impacts of climate change”, Newly appointed head of the Climate Change Authority Matt Kean said via a press release.

“This requires a major reorganisation of supply chains, production systems, industrial zones, energy sources, public and private finance, infrastructure and workforces”.

The Conversation published the below chart showing how Australia could fantastically lower its emissions to net zero:

The above chart is chock full of delusion.

“Preventing emissions from buildings requires, among other things, getting off gas and making them more efficient. Reducing emissions from transport means encouraging uptake of diverse solutions such as electric vehicles, trains and cycling”, The Conversation writes.

Annual Co2 emissions

Leaving aside the basic facts that Australia could cut all of its emissions and it wouldn’t make a dent in global terms, how is achieving net zero even remotely possible when the nation’s population is officially projected to grow by 50% in only 39 years?

Those extra 13.5 million people that are projected to arrive in Australia will require dwellings, cars, infrastructure, consumer goods, food, energy, etc, which will necessarily add to Australia’s carbon budget.

Accommodating those extra 13.5 million people will require around 6 million new homes to be built, accounting for demolitions, alongside massive amounts of new infrastructure and commercial buildings.

All of these things require energy and resources, which means more carbon.

For example, it was estimated that building construction, operation, and maintenance alone account for around one-quarter of Australia’s greenhouse gas emissions.

Researchers from Western Sydney University also showed that construction alone accounts for around 15% of global carbon emissions, whereas building operations contribute 27% of emissions:

Yet, the gaslighters at the Climate Institute and the net zero evangelists still claim that Australia can magically reach net zero by fantastically lowering emissions while magically sequestering carbon into land. It is pure fantasy.

How is buying a two-tonne Tesla Model Y with a 770 kilogram lithium-ion battery “green” and “net zero”? Similarly, how is building a concrete apartment with lifts and modern appliances “net zero”? I could go on and on.

The simplest way for Australia to mitigate carbon emissions is simply to stop growing its population like a science experiment via extreme levels of immigration.

Yet, the net zero evangelists ignore this simple truth and continue to spout the lie that Australia can grow indefinitely, enjoy modern lifestyles, and magically reduce the nation’s emissions to net zero.

It is a giant con job.
