Cost of stopping new coal and gas projects in freefall, costings reveal

Exclusive: The revenue the federal government would lose if it stopped all new or expanded thermal coal and gas projects has dropped by 80% in 2.5 years

As the fossil fuel industry appears increasingly shaky, the cost to the federal budget of stopping all new coal and gas projects in Australia has plummeted - costing less than 20% of what it was estimated to just 2.5 years ago, according to official parliamentary costings seen by Guardian Australia.

The Greens have a policy of approving no new thermal coal or unconventional gas projects in Australia. That includes new mines, as well as expansions to existing mines.
