The activist organisation recently released an eight-page report which found that all of Australia’s big four banks were great financiers of Australia’s biggest export industry.

But Greenpeace discovered that ANZ was ahead of its peers by providing nearly $A1.6 billion of total coal-related finance over the past five years.

Specifically for coal mining projects, the bank lent $727 million over this timeframe, with National Australia Bank taking second place in the report with $633 million of finance.

Yet the Commonwealth Bank was the biggest lender for crucial coal port developments, providing $440 million, and ANZ was in second place with $309 million.

NAB did not provide any lending in this area, according to the report.
