Communicating resourcefully: a natural field experiment on environmental framing and cognitive dissonance in going paperless

In a large-scale natural field experiment comprising 38,654 customers of a renewable energy supplier in the United Kingdom, we randomize environmental information and dissonance-inducing messaging to promote an active switch from paper to online billing. We find that environmental information and imagery is ineffective in inducing behavior change. Interestingly, the dissonance-inducing messaging weakly improves uptake by 1.2 percentage points among our main sample but backfires among a subsample of individuals with doctoral educations, decreasing uptake by 6.2 percentage points relative to a control group. Contrary to the majority of the literature on gender and environmental behavior, females in our sample are less likely to switch to paperless billing.
