Abstract
Climate change poses an urgent and existential threat to the wine sector. However, it is not easy for wineries and farmers to take action to reduce carbon emission comparing to adaptation. How can we encourage these actions? Farmers often seek information before take action, which influences their current risk perceptions of extreme weather condition or moral norms. Regarding the information, a positive approach focusing on empowering farmers to take action to address climate change is generally more successful at engaging people and minimizing defensive reactions. We therefore evaluate the impact of the “Leadership by Examples” flyer on the climate change-related information-gathering behavior of wineries in Japan. Leadership by example arises when individuals make sequential decisions, and the choice made by the first mover (the leader) influences the contributions of others (Jack and Recalde 2015; Gachter and Renner, 2018). We conduct a block randomized controlled trial for almost all wineries in Japan to evaluate the impact of the information provision on information seeking behavior: the control group receives normal climate related information and the treatment group receives the information with “Leadership by Examples” flyer. We further evaluate the impact on the wineries willingness to perform life cycle assessment (LCA). LCA allows wineries to understand their climate footprint, pinpoints opportunities for climate change mitigation, and tracks the impacts of emissions reductions over time. The heterogeneous treatment effects are also analyzed.

Experimental Details

Interventions

Intervention(s)
Our treatment is a flyer introducing a pioneering winery that engages in climate change mitigation. It is “Totto winery” in Tottori, Japan. One page of the flyer presents that Totto winery switched its electricity source to renewable energy and published the sustainability report. In addition, the flyer contains basic information regarding the winery. This treatment is based on the idea of “Leadership by example” as in Jack and Recalde (2015).

Primary Outcomes

Primary Outcomes (end points)
Our primary outcomes include: the number of registrations to the webinars, registration to the webinar 1 or 2, the number of participation in the webinars, participation to the webinar 1 or 2, application to be a subject of a life cycle assessment, and the number of days that a winery has been subscribing to the email newsletters from PRIMAFF since the experiment has begun.

Experimental Design

Experimental Design
380 wineries are randomized into two groups. We randomize the treatment at the level of the winery. Randomization is implemented by stratification. We stratify our sample wineries based on three variables: (1) a dummy variable indicating the treatment by postal mail, (2) a dummy variable indicating the response to our survey in March 2022, and (3) the region of the winery (zip code).
See Pre-Analysis Plan for more detail.
