New Zealand's Parliament has given the green tick to declaring a climate emergency - but the Climate Change Minister has admitted that not everything will be completely carbon neutral within five years.
On Wednesday, Prime Minister Jacinda Ardern made good on an election campaign promise to declare the emergency.
"The public sector needs to be and will be an exemplar that sets the standard we all need to achieve by 2050".
He says that they can't yet tell how much this move will cost, as parts of the public service that have distributed ownership schemes - something that Cabinet was told when they sought advice.
That was a sentiment shared by National, whose climate change spokesman Stuart Smith told MPs that Ardern's motion was "nothing but virtue signalling". "An acknowledgement of the burden that they will carry if we do not get this right and do not take action now", Ardern told lawmakers in parliament.
New Zealand joins 32 other countries including Japan, Canada, France and Britain that have declared a climate emergency.
"It is up to us to make sure we demonstrate a plan for action, and a reason for hope".
Christiana Figueres, who was executive secretary of the United Nations Framework Convention on Climate Change through the Paris Agreement talks, said the world expected more from Australia in the lead-up to the so-called COP26 climate talks to be held in Glasgow next November.
It is a lofty goal - there are now almost 16,000 vehicles in the Government's fleet.
Government agencies will now be required to "optimise their auto fleet" by purchasing electric vehicles or hybrids, when EVs are not appropriate for the required use, such as for some military purposes.
"There are some quite wide variety of estimates, anywhere from $200 million to $500 million".
That money will also help pay for another target - phasing out coal boilers in its ministries and agencies.
National opposed the motion - leader Judith Collins did not speak in reply to the motion and left the chamber halfway through the debate.
"It is unfortunately just another collection of words of the honest policy and concerted action New Zealand must take to drive down our emissions", she said. It says climate change will have a devastating impact on New Zealand through flooding, wildfires, sea-level rise and water availability.
Act was similarly critical - "Today's climate emergency was a triumph for post-rational politics with feelings rather than facts driving the Government's response to climate change".
The declaration was supported by the Council of Trade Unions - its president Richard Wagstaff said it signalled a more urgent move to a Just Transition for people working in carbon-based industries.
Greenpeace welcomed the declaration, but challenged the government to follow through with policy and action.
