New research conducted by non-profit organisation Jubilee Australia estimates Export Finance Australia, or E-F-A, has spent up to $1.69 billion in financing fossil fuel projects and related services over the past 11 years.
The credit agency is a commonwealth entity with an independent board.
It's self-funded with the money it spends going towards Australian export companies or their potential buyers, including overseas projects.
It's also helped finance the Ichthys [[ik-thiss]] L-N-G project off Western Australia's coast and the Wiggins Island Coal Export Terminal in Queensland.
The credit agency's mandate is to invest in sectors of national interest where there is a gap in private investment.
