CEM is a grassroots association working to put rigorous data and knowledge about pollution in the hands of impacted communities to hold polluters accountable and fight for healthy air and ecosystems.
We acknowledge the Traditional Custodians of Country, in particular the Gadigal, Wangal, Dharug and Dharawal on whose lands we work. We recognise their continuing connection to land, waters and culture and their fight against ecological and cultural destruction. We pay our respect to Elders past, present and emerging.


Our Projects

Reporting the Impacts of the Waste Industry
Foul odours are again plaguing residents in Western Sydney as floods and rain cause a crisis in the waste industry and raising further concerns about the NSW’s capacity to regulate powerful companies.

Low Cost Air Pollution Monitors
We have worked with Sydney locals to deploy dozens of low costs particulate pollution monitors across Sydney.
