Now the people who helped us feel betrayed by our net-zero conversion. Kel wrote on Facebook this week that he had been “lied to and let down”. Not only have we failed to dance with the people that brung us (although admittedly it would take a lot of rums for me to dance with Kel), we have been seduced by the siren song of cheap, green politics.

Net-zero emissions can only be achieved in one of two ways. Either the government taxes, punishes or just simply bans people from doing high-carbon-emitting things, or people just start reducing their carbon footprint without any compulsion. If it is the latter, why does the government need to do anything? If it is more likely the former, as night follows day, net-zero emissions will mean more red tape and more taxes.

That has certainly been the experience overseas. Britain is trying to get to net zero and to do so it is banning cars, heaters and it even wants to regulate meat eating. According to the UK Treasury this week, to reach net zero, Britain will need a carbon price of $295 per tonne – 10 times the size of Julia Gillard’s carbon tax.

How has the party of small government signed up to support big government? The best answer you get is that it is better for us to be in control of the move towards more and more intrusion into people’s lives. These people are Fabian greenies; they have surrendered to the idea socialism is inevitable but it will be better if we move towards it slowly.

Is the point of the Liberal and National parties to deliver Labor and Greens policies but just at a slower pace?

Now some argue everything will be fine because new industries will be invented that will replace the jobs of today. Many Australians used to be employed in the wool industry, they say, and now they are employed in mining and other industries.

But the mining industry did not emerge from Canberra. We didn’t tax sheep to invent the Jameson cell, and we didn’t ban blade shears to invent mechanical ones.

A Liberal-National Party government should strive for more jobs, not just different jobs. A net-zero emissions target will mean net-zero economic development for our nation.

This will leave Australia poorer and with fewer opportunities than we should have. We remain a nation with untapped water, agricultural and mineral resources. But a net-zero emissions target puts a shallow ceiling over our heads, limiting the reach of our grasp.

We must smash through this artificial boundary because the growth of our nation helps the battlers in small towns who just want a better future for their families. While I am disappointed at the decision of my party room to adopt a net-zero emissions target, I will stay in the room because when you leave after losing an argument, the only people that win are those you oppose.

Australia is about to have a long lesson in the school of hard knocks. We can already see the calamity that is net zero in Europe, where they can’t keep their lights on, they have lines at petrol stations and even food supplies are under stress. I wish we didn’t have to suffer this experience before we regain common sense, but I will continue the fight to have us graduate from this punishing school as fast as possible.

About a year after the election I met Paul at the Grand Hotel in Clermont one night. Paul had a job driving trucks loaded with pipes for the Adani mine. He was struggling to find work beforehand. He praised Adani and loved his job. If the greenies had their way, he would probably be on the dole.

There are not many people left in Canberra fighting for the blue-collar workers of Australia. I will keep fighting for Paul and the many others who just want a job and to see their country prosper.
