Climate change is real and it is caused to a significant extent by human activity.

Any sort of political correctness needs to be swept out of the way

The Prime Minister seems now to be basing his re-election campaign on this plot line. He is saying to the Australian people, look out, the baddies behind you - hiss, boo and whatever you do, don't vote Labor. This political parody of pantomime is looking and sounding desperate.

My guiding principle is that prosperity can be shared. We can create wealth together. The global economy is not a zero-sum game.

We encourage China to engage as a good global citizen and we are clear-eyed about where differences do lie.

We are constantly being told that we've never been wealthier. And many of us are. On average we all are. But that's just the problem.. no one is average.

If we change the way the electricity sector operates, we can bring down our levels of carbon pollution, and continue the crucial task of tackling climate change. Putting a price on carbon would do this.
