The federal government could have support for its signature emissions reduction proposal if it agrees to stop opening new coal and gas projects.
The Greens have revealed the position will underpin their support to pass Labor's changes to the safeguard mechanism, which is a key part of its climate change policy and aims to cap the emissions of Australia's 215 biggest-polluting companies.
Those breaching the limit would be forced to buy carbon offset credits or trade their emissions with other companies.
