Like so many people, he can't make the cutting-edge technology work for him just yet.

"Electric vehicles are absolutely the way to go but the reality is widespread uptake is about 10 years away," Mr Whitelaw told AAP.

But being a former Google engineer, he's managed to build a whole business around the idea that most people will have to keep driving their greenhouse-gas emitting petrol cars for some time.

He's designed an online platform called Go Neutral, where motorists can directly offset one year's worth of carbon emissions from the average car.

"People are looking for more things they can do to make a difference but they often feel stuck," Mr Whitelaw said.

"There are 20 million cars in Australia; we think it would be great if we could make one million of those cars carbon neutral."

Go Neutral customers pay $90 to offset 3.2 tonnes of carbon dioxide, which is about what the average car produces each year.

The company then buys carbon credits generated by environmental projects around Australia.

Customers are rewarded with a bright orange car bumper sticker that is designed to be highly visible to other drivers.

"Absolutely it's virtue signalling - but I don't think that's a bad thing," Mr Whitelaw said.

While the idea of carbon abatement isn't new, the market has not been very accessible for individual consumers and Mr Whitelaw hopes his company will be the first to change that.

Go Neutral only has about 900 customers so far but has already caught the eye of carbon farming firm Green Collar, which announced the acquisition of Go Neutral earlier in May.

Green Collar CEO James Schultz told AAP the sale means Go Neutral's carbon credits will be directly linked to his company's environmental projects, so customers can see exactly where their money is going.

Green Collar's projects cover about 15 million Ha, and generate roughly five million tonnes of carbon abatement each year, mostly through land regeneration and improving soil carbon and livestock management.

Mr Schultz believes the Go Neutral model will be the first in the world to offer carbon abatement for individual vehicles on a large scale.

"It has the ability to get to the scale of the solution we need ... There is no shortage of people who are really keen to take action," he said.

Green Collar has been working on carbon abatement measures with landholders for the past 10 years, using tested accounting methods to calculate how much carbon dioxide its projects absorb.

"We can put a tape measure around a tree and know how much carbon it's taking up," Mr Schultz said.

While Mr Whitelaw says government action will make the most difference on climate change, he believes there's a growing appetite for individuals to take responsibility for their own carbon emissions.

"It's all about connecting normal people with meaningful climate action," he said.
