To people interested in the environment the phrase “Indonesian coal” tells us two things really quickly.
Firstly, that it comes from an industry that’s deforesting, killing orangutans etc. The Indonesian mining sector is open cast, meaning they tear up the rainforest to get at the coal. Obviously you can’t remediate that, not that they try hard, and it pollutes, causes flooding, and destroys livelihoods as well.
Secondly, Indonesia’s coal is sub-bituminous. That’s a crappy low grade kind of coal that releases way more greenhouse gasses than high grade coal.
Edit: Shane Jones might well be trying to use racist overtones like you and @Dave said, I’m just saying calling it “Indonesian coal” isn’t inherently race whistling.
