Malcolm Turnbull On Climate Change

During my time as Environment Minister three points about climate change became very clear to me and you will have heard me making them often. They bear repeating today.
The first is obvious: climate change is a fact, not a theory. By that I mean that whatever reservations people might have about the science, policymakers must, as Rupert Murdoch once observed, “give the planet the benefit of the doubt.”
The second point is less obvious. Given that so much of our emissions are from sources that are likely to be very hard to abate either at all or at realistic cost, the emission reduction goals we are setting ourselves for 2050 will mean in practical terms that we will need in 42 years to have a world where all or almost all of our energy comes from zero emission sources and where deforestation, currently the source of 20 per cent of global emissions, is replac
ed by a global programme of reforestation – an initiative I was proud to have pioneered while Environment Minister in the Howard Government last year.
This would mean that there would be no coal fired power stations unless the CO2 was captured and stored safely under the ground. Automobiles would be electric – a whole energy hungry world would have to undergo an industrial and technological transformation of a kind never seen before in its global scope and scale.
The third point is that there is no prospect of achieving the massive global reductions in emissions that science demands unless all of the major emitting nations both in the developed and developing world play a part. Until a few years ago that was a controversial statement, but as always the relentless logic of arithmetic has won the day. Indeed, as we saw at the US President’s first Major Economies Meeting on climate last September even if the developed world cut its emissions by 100 per cent by 2050, to achieve a global reduction to 50 per cent of 2005 levels, the developing world would need to cut its
emissions by 47 per cent.
