Karen Spehr and Rob Curnow are environmental psychologists and co-authors of the book Litter-ology: Understanding Littering and the Secrets to Clean Public Places. As co-directors of Community Change, they have been working on changing people’s behaviour in relation to the environment for over 20 years.

In partnership with environment protection agencies, local and state government and both large and small environment agencies in Australia, New Zealand and the United States, they have worked to reduce littering in public places and achieve changes in household water use and energy saving. They specialise in matching what people say they do with what they actually do to achieve long-term measurable change.

For their work on littering behaviour, they received an Australasian Environmental Excellency Award.

Karen and Rob live in Melbourne, Australia.
