The future of one of Labor's signature climate policies - updating the safeguard mechanism to deal with industrial greenhouse gas emissions - hangs in the balance. The government held off pushing it through parliament this week while negotiations continued with the Greens and key independent senator David Pocock over a potential deal to strengthen it.

The design of the policy is not the Greens' responsibility, but what happens next is largely up to its party room - with the Coalition opposed, the government can't get its legislation through without their support. The minor party is divided. Its 15 members will meet through the weekend ahead of a potential decision by Monday. It could go either way. Given the party operates on a consensus model that allows time to find common ground, it could also remain unresolved into next week.
