The Green Party wants all new bills to be subject to vetting for its effects on New Zealand's greenhouse gas emissions.
Co-leader James Shaw announced the new policy at a conference in Wellington today for Green parties around the Asia-Pacific region.
"National makes too many decisions based on short term goals, like trying to win the next election," he said.
The Greens have drawn up a bill titled the Climate Impact Disclosure Bill but for it to be even debated in the House it would need to be drawn from the ballot for private members' bills.
"This bill will ensure the Government at least considers the impact new laws will have on the long term, future generations, and the environment," Mr Shaw said.
