Global dairy giant Nestle has withdrawn from the Dairy Methane Action Alliance, prompting speculation.

This follows other companies backing out of climate initiatives, with the Net Zero Banking Alliance confirming it was set to shut down earlier in the week.

Agribusiness expert Dr Jacqueline Rowarth says it's likely the Alliance didn't move fast enough for Nestle, and they're taking their support elsewhere.

"The Alliance has not worked as well as they thought - and remember, Nestle's done some really good work around the world with regenerative agriculture, with cropping... so they're putting their money where they're actually getting action."
