WESTPAC has been named the world's most sustainable corporation at the World Economic Forum in Davos.

Australia's second biggest home lender and deposit holder topped a list of 100 corporations, which also included rivals ANZ and Commonwealth Bank, plus Coles owner Wesfarmers and property developer Stockland.

The bank also beat Japanese car maker Nissan, German sportswear brand Adidas, Korean electronics maker Samsung, American beverage giant Coca-Cola and confectionary maker Nestle.

The annual Global 100 award from Canadian investment research company Corporate Knights recognises companies which reduce energy use, demonstrate impeccable safety credentials, minimise employee turnover and promote leadership diversity.

Westpac chief executive Gail Kelly, Australia's most high profile female corporate leader, said social, environmental and economic responsibility were part of the bank's culture.

"I am delighted that Westpac's sustainability performance has been rated so highly on the global stage," she said in Davos.

"It is wonderful recognition of the work of our people to help create a sustainable future and deliver long term value for our customers, employees, shareholders and the community."
