Vestas has been named the world's most sustainable company in the 18th ranking of Corporate Knights, which stressed leading green performers like the Danish wind turbine manufacturer will in future deliver more viable returns than global peers.

The ranking is based on an assessment across a range of sustainability metrics at 6,014 companies with more than $1bn in revenue. Circularity and ambitious carbon emission reduction targets were highly prevalent among high performers on the index.

“We are rapidly moving towards a future where leading sustainability performers like Vestas will drive more viable returns than their global corporate peers,” Corporate Knights chief executive Toby Heaps said.
