Cost-effectiveness analysis of a program promoting a vegan diet

Abstract

This report analyzes Challenge 22, a program run by the Israeli charity Animals Now, that promotes veganism and reduction in meat consumption. The cost-effectiveness of the program is evaluated based on a 2019 survey study of Israeli participants. The study found that every 1 ILS donated to the program corresponds to a reduction in meat consumption of 1 to 12 portions per participant over 7 months. While the study suggests that these dietary changes could persist for longer periods, the analysis is subject to limitations. These include a lack of causal evidence, the generalizability of findings from Israeli participants to the program’s entire reach, and the reliance on self-reported data. Despite these limitations, the report highlights Challenge 22 as an exceptional program in Israeli philanthropy in terms of transparency, measurement, and evidence for positive impact. – AI-generated abstract.
