The inaugural Barwon South West Climate Alliance is a proposed partnership between ten councils and four land management agencies to work towards preventing and mitigating the impacts of climate change in the region.

Benefits advertised include 'climate leadership, cost savings, greenhouse gas emissions reduction, access to grant funding, advocacy at regional, state and national levels and access to regional climate risk data.'

There are eight established regional climate or greenhouse alliances across Victoria and this would be the first for the south-west.

Warrnambool City Council is auspicing the alliance, and Moyne Shire, Glenelg Shire, Southern Grampians Shire City of Greater Geelong, Golden Plains Shire, Borough of Queenscliff, Colac Otway Shire and Surf Coast Shire have been invited to join.

Warrnambool City Council Mayor Vicki Jellie said it was important to provide a unified voice for climate change in the region.

"It's important that we work together to establish something like this," Cr Jellie said.

"By doing it all together we can share knowledge across councils, sectors and the region.

"Through this we can coordinate a range of mutual benefits on climate projects across the region.

"It benefits everyone if we're all in it."

It would be self-funded with membership proposed at $15,000 a year for councils and $10,000 for other organisations.

Corangamite Shire Council said it would be interested in joining the next stage of the alliance formation.

"I think we need to be involved in the next stage to ensure that this potential alliance will be worthwhile and useful to us," Cr Geraldine Conheady said.

"This proposed alliance has the potential to be very useful and supportive way of working with other councils and organisations on projects.

"I think this is logical and prudent."

Moyne Shire Council Mayor Daniel Meade said the council will formally decide on its membership at its September meeting.

Corangamite and Glenelg Hopkins Catchment Management Authorities, Barwon Water and Wannon Water and the Department of Environment, Land, Water and Planning are also part of the proposed alliance.

The objectives of the BSWCA align with the state government's long-term vision and approach to climate, including targets to reduce emissions by 28-33 per cent by 2025 and 45-50 per cent by 2030.
