The Greens are revealing parts of their alternative budget - set to cost about $8 billion over four years.
It's calling for a Ministry of Green Works, a Government agency supporting sustainable infrastructure - including regional forestry.
The party estimates it would create 40,000 jobs.
Co-leader Chlöe Swarbrick won't release more details - but says their costed independent budget will be released in about two weeks.
"In about a fortnight's time, we'll be unveiling our Green budget, which will show people how we can have an economy that reduces the cost of living, improves quality of life and also reduces climate-changing emissions."
