There are ways to leverage your coal mines to be part of your national energy system, employing the miners and leaving the coal unburnt and in the ground. You are slow down under, but you will get there like it or not.
Will get there eventually, maybe.
Zero-emissions means no camp fires...no jet engines,...
The goal is net zero CO2 not zero emissions. If you burn campfire wood from a sustainable woodlot, there is no CO2 rise because new growth for the next crop absorbs it. If a jet engine burns plant derived kerosene, same basic idea. The point is to phase out fossil fuels, whose use liberates carbon that was sequestered underground over millions of years. One good start is shifting your energy sources and economy, so you don't have to sell brown coal to China to make ends meet. Which in turn motivates China to accelerate their shift away from coal.
LOL!
In 1965 under LBJ global warming alerts were based on 11.85 billion tons of CO2
By 1979 the Charney Report had them at 19.78 Billion
The first UN IPPC findings in1990? 22.7 Billion
This year the 6th edition of the IPCC put CO2 emissions at 36 billion tons.
If anyone was serious about reducing CO2 in the last 55 years we would have a carbon tax by now.
But we do not
What we do have is the power to adapt to climate change.
As we have always had.
That will be cheaper for people 100 years from now than it would today by eliminating fossil fuels.
