In a previous study, we investigated the impact of an awareness-raising campaign on the behaviour of secondary school children in the Centre Region of France, regarding the recycling of used batteries. But, was it a question of pro-environmental behaviour or simply an environmental action? To answer this question, a three-year longitudinal study was carried out, revealing that the awareness-raising campaign had a greater impact on stabilizing the children's behaviour than on the adoption of sustainable pro-environmental behaviour.
