This study estimates willingness to pay (WTP) for a range of different reductions in litter and illegal dumping, including:
- reductions in the proportion of places that have noticeable litter
- reductions in the amount of litter at places with noticeable litter
- reductions in the frequency with which people see illegally dumped waste, and
- reducing litter and illegal dumping to zero.
It estimates how these values vary across different types of sites, including both natural and built environments, across different types of litter and illegal dumping, and across different states. It also estimates the personal characteristics that are most correlated with WTP to reduce litter and illegal dumping.
