Litter Research & Reports
Nobody Trashes Tennessee is a campaign that seeks to reduce the amount of roadside litter in the state. To better understand the nature of this problem, research was conducted to assess the amount and type of debris found along Tennessee’s roadsides.
The campaign is based on three primary litter studies; one conducted in 2006, one in 2016, and another in 2022.
In addition, our latest research phase in 2022 tested litter behavior and identified messaging that might drive behavior change.
