As transport is some 30 per cent of emissions and, of that the heavy transport that we rely on to produce and deliver our food etc., cannot become electric, and hydrogen fuel cells are little way off yet, so that leaves cars that will have to make up the huge balance in reductions.

Can we all have electric cars by 2030 charging from our home solar panels? Doubt it.

Also ships and planes cannot be electric so personal travel will need to be reduced drastically.

Electric power generation is another some 30 per cent of emissions and we only have eight years to get all the renewables and the grid ready, not only for power but green hydrogen generation.

Agriculture, that feeds us, is another big emitter so are we all going to be vegetarian with a sprinkling of kangaroo?

It is going to be a lot of meat for us to eat to reduce the ruminant population by 2030 and that does not account for the feral ruminants like camels and buffalo which cannot be culled in electric helicopters.

And that is not to mention fertiliser that is needed to grow the food for an ever-increasing population, as called by some to ease the labour shortage, with some even wanting a higher floor reduction in emissions.

I am waiting to see the plan for the Australia, and the world, but whatever they are it is going to be a big shock to the system as we are hooked on cheap energy that has given us untold freedom.
