This study explores the spillover effects of an environmental education program on non-participants, particularly focusing on the bi-directional transmission of pro-environmental behaviors between children and parents. Through a randomized experiment with 1,545 child-parent pairs in Patna, India, we examine how participation in the program affects environmental knowledge, efficacy, and behaviors. Our design divides student-parent pairs into control, child-only, parent-only, and child+parent participation groups, allowing us to analyze both the direct impact of participating in the program and its indirect spillovers within families.

Experimental Design

Experimental Design
The intervention is the environmental education curriculum designed to promote sustainable behaviors.
In the experimental design, the 1,545 child-parent pairs (a total of 3,090 participants) are divided into four groups: a control group with no exposure to the curriculum, a child-only group (T1) in which only the child participates in the course, a parent-only group (T2) in which only the parent participates in the course, and a joint child-parent group (T3) in which the parent and child participate together in the course. We measure the effect of the course on the direct participants and their familial counterparts. Having a control group and a joint participation group (T3) allows us to effectively delineate the minimum and maximum impact on the household and isolate the effects of the intervention on both direct participants and their familial counterparts.
