Looking at a graph of UK GHG emissions, I was quite surprised to see that they had reduced from a peak of about 650 MT/year to less than 400 MT/year, and were still in steep decline.
I wondered how Australia was doing, and it was surprisingly hard to find the data.
But this looks like a pretty good summary:

I suppose the good news is, coming from such a high base, it should be easy to achieve substantial reductions.
