The aim of this project was to encourage volunteers to take a more active role in the local government’s ‘Eco Village’ programme. We designed a two-arm randomised controlled trial, through which we tested longer monthly messages about environmental challenges (Treatment 1) compared to short, weekly messages that drew on behavioural insights (Treatment 2) over the course of three months. Treatment 2 led to neither significantly higher volunteer retention or more engagement when compared with Treatment 1.
