About Litter Intelligence

We cannot improve what we do not measure. Litter Intelligence is a long-term programme that collects litter data, provides powerful insights about the problem, and inspires widespread action for solutions. Led by New Zealand charity Sustainable Coastlines, the programme works in close collaboration with the Ministry for the Environment, Department of Conservation and Statistics New Zealand.
