How to promote green travel effectively: a study of niche information interventions based on meta-analysis

Green travel is an effective way of conserving energy and reducing emissions. It is the result of consumers’ behavioral choices, and consumer behavior is largely influenced by external information. The question of whether and how the consumer uptake of intervention information affects consumer green travel behavior has yet to be systematically studied. Based on 22 English-language publications from 1977–2022, meta-analysis was used to quantify the effects of niche information intervention strategies on green travel behavior and to explore the relevant factors that influence the effect of interventions. The results indicated that niche information interventions had a positive effect on green travel behavior. Other factors such as information type, the test sample, intervention duration, intervention frequency and intervention timing are considered to affect the intervention effect through subgroup analysis. The optimal intervention modes were identified as follows: the information type of coupling at least three kinds of information, the non-student sample, an intervention duration of less than one month, an intervention frequency of once only, and the intervention timing of coupled antecedent and consequence interventions.
