A Greens backbencher in the ACT's parliament will push for the territory government to sign an international fossil fuel non-proliferation treaty.
If the ACT government agrees to sign the treaty, it would be the highest level of government in the world to do so.
Internationally, only six city- and municipal-level governments have signed the treaty, including the cities of Los Angeles, Barcelona and Vancouver.
The treaty, based on the idea of the nuclear non-proliferation treaty, calls for an end to new fossil fuel exploration and expansion, the phasing out of existing production and the development of equitable transition plans.
ACT Greens backbencher Jo Clay will lodge the motion on the floor next week.
"I'm proud to be the first in Australia to table a motion in relation to this fossil fuel treaty, and that we now have a chance to lead the world in becoming the highest level of government to support the call," Ms Clay said.
"Just like declaring a climate emergency, declaring our support for a fossil fuel non-proliferation treaty is empowering, demonstrating how even small jurisdictions can lead by joining with other cities, states and nations to speak with one clear voice."
As part of the motion, the government would send a letter to urge the federal government to also endorse the treaty, along with other states and territories.
Federal Greens leader Adam Bandt has thrown his support behind the motion and said the Greens would push the federal government to do the same.
"Fifty years ago the existential threat posed by nuclear weapons brought the world together behind a nuclear weapons treaty. Today the greatest threat to our existence is climate change," he said.
"This treaty on fossil fuels would seek to ensure that no worker is left behind by ensuring countries implement measures like investing in guaranteed re-training."
