Auckland Council wants to charge households a climate levy, so it can increase the amount of buses, ferries, cycling and walking options in the city.
The council is proposing a $1 billion climate action package in its annual budget for 2022/23.
The package would be funded by a Climate Action Targeted Rate (CATR) that will raise around $574 million over 10 years, ringfenced for direct climate action.
Funds raised would be leveraged to seek a further $471m through central government co-funding and other sources.
Auckland Council declared a climate emergency in 2019, had committed an extra $15m a year to climate action, but was not doing enough, Auckland mayor Goff said.
"A recent progress report on our Climate Action Plan states that Auckland's emissions are not remotely tracking in line with our target to reduce emissions by 50 per cent by 2030."
The planned funding includes a more than half-billion-dollar boost to deliver new and frequent bus services across the region.
"This would mean 170,000 more Aucklanders - 10 percent of the population - not previously well served by public transport would live within 500 metres of a frequent bus route.
"Encouraging a shift to public transport is the most effective way of reducing transport emissions, which make up more than 40 per cent of our city's emissions profile," Goff said.
For a median-value home worth $1.18 million, the levy will be about $1.10 a week, he said.
"While nobody relishes the idea of paying more rates, we've heard clearly from Aucklanders that they want us to do more on climate change and to improve our public transport system. We must be able to say to future generations that we used every tool in the toolbox to tackle the climate crisis."
The Climate Action Targeted Rate is to deliver:
170,000 more Aucklanders living within 500m of a frequent bus route
$122 million to accelerate decarbonisation of the ferry fleet, which accounts for 21 per cent of Auckland's emissions from public transport
$228 million for walking and cycling
$13.3 million for urban ngahere, māra kai (food gardens) and tiny forests
New frequent bus services in Manukau, Manurewa-Papakura, Maungakiekie-Tāmaki, Waitākere, Whau, Albert-Eden-Puketāpapa, Rodney, Albany, Ōrākei, and Franklin wards and service level improvements throughout Auckland
An additional 66 low-emissions buses for Tāmaki Makaurau
An additional 18km of safe cycle facilities
Up to 35km of walking connectivity improvements
14,800 native mature trees with a focus on areas with the most heat vulnerability and lowest canopy cover (mainly in south Auckland).
