There's been a growing uptick in corporations ditching their green ambitions.

Volvo Cars has abandoned its ambitious target to sell only electric cars by 2030 amid a global slowdown in growth for battery-powered vehicles.

Sweden has recently scrapped their aviation tax on airline tickets in a bid to reduce prices and boost availability.

Griffith Business School associate professor Dr Rob Hales says more businesses have decided to keep their targets quiet amid accusations of green-washing.

"Green-hushing is keeping your targets and keeping the mechanisms to try and get there a bit quiet. There's been some industry studies to show that up to 25 percent of businesses are actually disclosing, in public, what their targets are."
