We know who Australia’s biggest polluters are. Every year, the government publishes data on the largest sources of scope 1 greenhouse emissions (that is, directly produced as part of the production process of a facility) and scope 2 emissions (indirectly produced). Unsurprisingly, that list — led by AGL Energy — is dominated by large coal-fired power companies and gas companies.

But the list doesn’t capture scope 3 emissions (emissions produced indirectly by a business) and it particularly doesn’t capture the scope 3 emissions from the burning of Australian thermal coal exports around the world.

Nor does it capture the impact on emissions and climate policy of a company’s actions.
