Super giant HESTA divests coal

The $52 billion super fund for healthcare workers has divested holdings in thermal coal companies under a new climate policy that commits to "net zero" emissions across the entire portfolio by 2050, according to The Age.

HESTA's updated climate plan involves reducing absolute carbon emissions across its investment portfolio by 33% within the decade and 100% by 2050, in an effort to bring its investment strategy in line with the goals of the Paris Climate Agreement.

The role of large super fund investors to limit emissions has increasingly come to the fore after the Intergovernmental Panel of Climate Change report found there would be "long-lasting or irreversible" impacts to the environment if warming exceeded 1.5 degrees.
