The world's warming - but concern about it may be cooling.

An Ipsos survey's found numbers are falling of New Zealanders saying we're failing future generations by not acting on climate change - down nine percent since 2022.

It also found fewer Kiwis believe businesses not combating global warming, are failing staff and customers.

Managing Director Carin Hercock told Heather du Plessis-Allan it seems to be a global trend.

She says it's a post-Covid and high-inflation impact, as countries with higher inflation experience a softening in climate commitment.
