This research is based on Kollmuss and Agyeman's mode, and aims to determine if the prerequisites for pro-environmental behaviour, such as the collection of used batteries at school, are ethical, cognitive and environmental. A questionnaire/opinionnaire was given to 102, 14-17-year-olds to gather data on: (1) their current recycling habits, (2) their environmental values, (3) their level of knowledge about the harmful effect of used batteries on the environment, (4) their attitude towards collecting used batteries, (5) their attachment to the neighbourhood, (6) their perceived behavioural control and finally (7) their intention to act. The number of used batteries brought by each school child was recorded over a four-month period. Results show that young people's behaviour of collecting used batteries can be predicted by ethical (pro-environmental values), affective (neighbourhood attachment) and cognitive (perceived behavioural control) variables (R[superscript 2] = 0.38; p greater than 0.01).
