Auscoal Super has added two investment managers to its international equities portfolio.
Acadian Asset Management will manage a $97.5 million mandate that will use a low volatility strategy.
The superannuation fund will also invest about $78 million in the Colonial First State (CFS) Asian Sustainability Fund.
The CFS fund adopts a sustainable investment approach.
"Sustainable investment is growing in importance. Auscoal Super is increasingly considering environmental, social and corporate governance factors when making investment decisions," Auscoal Super chief executive Bruce Watson said.
Watson said Acadian's strategy will reduce the risk of the fund's international share portfolio without compromising returns.
Auscoal Super's international share portfolio has $975 million in funds under management.
