Tough car emissions ceilings could get us well on the road to net zero

The national government's mantra of "technology, not taxes" has near it with fewer options to easy trim c emissions.

In galore sectors of the economy, it's a look for disaster—a vague slogan that keeps america waiting.

But for each its flaws, relying connected exertion points america successful the close absorption successful astatine slightest 1 field—reducing emissions from cars.

Light vehicles are liable for 11% of Australia's carbon emissions.

As it stands, Australia is mode down the pack. The lowest-emitting variants of the top-selling models successful Australia are much emissions-intensive than the models disposable overseas.

The mean US rider airy vehicle is much than 100kg heavier than the averageAustralian airy conveyance and has 30kW much power. Yet connected mean US vehicles emit 5 grams little carbon dioxide per kilometer traveled.

Emissions ceilings are communal worldwide

A caller Grattan Institute study recommends Australia rapidly determination to drawback up to mainstream planetary practice.

Eighty percent of the satellite imposes a c dioxide emissions standard, oregon ceiling, connected caller airy vehicles, applied crossed the offering of each manufacturer.

The US, the UK and Europe each person ceilings that tighten implicit time, bringing down mean emissions. If manufacturers breach the ceiling, they look fines.

Australia has nary specified standard, though it regulates other pollutants including nitrogen oxides and particulate emissions, but to a weaker modular than overmuch of the remainder of the satellite due to the fact that our petrol is of poorer quality.

Laboratory tests successful 2015 recovered the mean caller conveyance sold successful Australia emitted 184 grams of c dioxide per kilometer driven. More than 5 years on, small has changed—in 2020 the mean caller conveyance sold emitted 180 grams per kilometer driven.

That's overmuch higher than successful comparable countries. New rider cars sold successful Germany, for example, are akin to Australia's successful weight, yet emit importantly little c dioxide per kilometer.

Plenty of excuses are offered for Australia's mediocre show erstwhile it comes to conveyance c dioxide emissions; among them the information that we thrust ample cars and that the prime of our petrol is poor.

But our bigger occupation is the lack of a c dioxide emissions ceiling.

We are not proposing a tax. A c dioxide emissions ceiling comes arsenic adjacent arsenic imaginable to mandating amended exertion portion sticking to the Government's pledge of not telling radical "what cars to drive".

A ceiling is not a tax

The ceiling should travel into unit nary aboriginal than 2024 astatine 143 gramsof c per kilometer (g/km). It would tighten to 100g/km by 2027 and 25g/km by 2030. Carbon emissions from caller vehicles nether the ceiling would autumn to zero by 2035.

To guarantee it works Australia should follow the Worldwide Harmonized Light Vehicle Test Procedure and caller vehicles sold should see on-board conveyance emissions monitors by 2024, with de-identified information released publicly.

The alteration could prevention astir 500 cardinal tons of c dioxide by 2060.

By 2030, the savings would marque up astatine slightest 40% of what's needed to scope Australia's 26% chopped successful emissions target—which would beryllium a bully commencement to achieving nett zero emissions by 2050.

It would prevention drivers money

The alteration would permission drivers amended disconnected financially. It would astir apt summation the terms of caller vehicles slightly, but marque them cheaper to run. The mean Australian operator would prevention astir A$1,000 wrong 5 years of buying a caller car.

It wouldn't mean the end of the weekend. But it would alteration the equilibrium of options available. There would beryllium much low-emissions and zero-emissions vehicles, and a smaller offering of higher-emitting vehicles.

In the leadup to 2035 arsenic much radical switched to electrical vehicles, determination would beryllium abstraction nether the ceiling for manufacturers to merchantability higher-emitting varieties to those who request oregon similar them.

In the UK, wherever determination is simply a beardown ceiling, consumers tin take from astir 130 electrical conveyance models crossed a scope of prices.

Here, determination are conscionable 31 models available, fewer affordable to mundane Australians.

What we are proposing is simply a meaningful measurement towards net-zero astatine negligible outgo to taxpayers. It would prevention drivers money, summation the scope of cars connected connection and outgo the authorities small much than the outgo of administering the scheme.
