Parker Fitzgerald: Optimising the Risk and Return of Climate Change

By Parker Fitzgerald

Mitigating climate change is not just an environmental responsibility – it is also an economic necessity.

Governments globally are making concerted efforts to mitigate the impact of climate change.

Delivering this commitment will be a significant undertaking.

Private finance must be mobilised – and banks will be called on to enable and safeguard this transition.
