The Greenhouse Alliances are formal partnerships of varying numbers of councils (and other organisations) driving climate change action across 70 of Victoria's 79 municipalities. The Alliances work across their networks, communities and partners to deliver regional mitigation and adaptation programs. This includes the implementation of joint initiatives that provide economies of scale and enable projects typically beyond the reach of individual councils. Our project work is complemented by targeted advocacy, capacity building activities and regional partnerships. The alliances include:  The Greenhouse Alliances’ Executive Officers and Regional Coordinators meet bimonthly to share information and resources and contribute to expanded regional action on climate change.
