Australia's Clean Energy Finance Corporation (CEFC) has invested 1.7 billion U.S. dollars in various projects for the last financial year.

CEFC said on Monday that in the 12 months leading up to June 30, 1.7 billion U.S. dollars was invested across 39 clean energy projects, an increase of 147 million U.S. dollars on the previous year.

The CEFC was established by the Australian government in 2013, receiving 1.47 billion U.S. dollars every year to invest in industry sectors with the strongest potential to reduce the country's carbon emissions.

Since 2013 the CEFC has made investments exceeding 4.8 billion U.S. dollars with an estimated total project value of 14 billion U.S. dollars.

This year's investments included 10 large-scale solar projects and four wind farms, with the CEFC aiming to cut carbon dioxide equivalent emissions by 10.8 million tons per year.

"We have directly invested in more than 110 individual transactions and delivered finance for more than 5,500 smaller scale clean energy projects," CEFC chief executive Ian Learmonth said.

Learmonth said that in the past financial year the CEFC has "maintained our role as a leading investor in Australia's renewable energy sector and further extended our reach into emissions reduction activities."
