QLD mine won't go ahead: Greens leader

Greens Leader Richard Di Natale believes the proposed Carmichael coal mine will not go ahead - not because of a Federal Court ruling but because the market no longer supports coal.

The Queensland government insists the project will go ahead despite the Federal Court last week ordering the mine's approval be set aside, when a legal loophole in Environment Minister Greg Hunt's decision was discovered.

But Senator Di Natale told ABC's Insiders program the project won't go ahead.

"This has now become a mainstream economic view, that coal is an industry that belongs in the last century."
