Macquarie Capital has expanded its Green Investment Group (GIG) operation into North America, giving global reach to the business that started life in the UK as the world’s first green bank.

Extending its activities across the Atlantic confirms the ambition to establish GIG as a “global, pioneering green investment platform”, said Macquarie Capital.

The Australian finance house acquired GIG – formerly known as the Green Investment Bank and set up in 2012 to spur British low-carbon investment, notably in offshore wind – in a $3bn deal when it was privatised by the UK government in mid-2017.
