Emissions Reduction Plan: Details of scrap-and-replace scheme revealed

Got your eye on a secondhand Prius on TradeMe? Good news. You might be eligible for $10,000 to snap it up.

More detail has emerged about the Government's scrap-and-replace scheme for old gas guzzlers, including who is eligible, but questions remain over whether the electricity grid will cope if everyone tries to charge their car at the same time on a cold night.

Families and individuals eligible will have to earn less than the median household income - around $85,000 - vehicles in line for the scrap heap will need to be eight years or older, and you'll get about $10,000 to trade in your car.

You can use that to buy a zero- or low-emissions vehicle like a hybrid or an e-bike - these can be second-hand.

Not everyone's onboard though. ACT said Kiwis should instead get a $1000 tax refund from the Emissions Trading Scheme - which will fund this plan.

"We think solving climate change is simple," said ACT's climate change spokesperson Simon Court. 

The simple suggestion? That MPs simply spend less time in Wellington - because less travel to the capital means fewer emissions.

"Would you put your money in your bums where your mouths are?"

Climate Change Minister James Shaw said ACT's "proposing climate change policies so that they can pretend they're not climate deniers while also pretending that they are".

It's not the clean car scheme that's got on the goat of the National Party - but the $678 million allocated to help industry decarbonise.

"The amount of money that's being spent on corporate welfare, our view is very clearly that the taxpayer shouldn't be subsidising big corporates to make emissions reductions," said leader Christopher Luxon. 

Deputy Prime Minister Grant Robertson said "it's an interesting day in the house when the National Party opposes profit". 

While the Government is working to win over the Parliament on its plan to reduce emissions, it's already got the support of energy sector experts who say New Zealand is well-placed to meet renewable energy demand. 

Newshub's been told power company Transpower got more than 10 connection requests from large scale solar projects in the last month.

"The problem really comes when the entire electricity network is really stressed, so that'd be a really cold evening in the middle of winter," said energy sector consultant John Hancock.

That can be solved by staggering the times that people charge their cars, which can also act as batteries while they're hooked up to the grid and could feed back at peak times like when people are cooking dinner.

"We've got to increase the uptake of smart charging technologies at people's houses so we're charging cars outside of our peak demand areas," said Energy and Resources Minister Megan Wood. 

Convenience and lower cost, a carrot the Government hopes will get those fond of their fossil-fuelled cars over the line.
