Personalised support for behaviour change was offered to 6,000

households using the GD6D tool developed by E3D-Environnement,

based on the findings of behavioural sciences, to help them adopt

everyday actions that reduce their waste production and increase their

contribution to sorting and recycling.

Rather than a reward system, which does not sustain changes in

behaviour (if the reward stops, the new behaviour stops too), the aim is

to identify and leverage people’s deep-rooted motivations so that the

change comes from them and settles in.
