This report analyzes Alipay’s Ant Forest’s exponential growth and its trajectory and vision to unlock the power of individual behavior change for climate change mitigation. It explains how this green initiative (via digital functions) has managed to encourage users to engage in low-carbon activities in their daily life. It estimates that the market size for an innovation such as Alipay Ant Forest is roughly 3 times the current population of the United States, noting that up to 8.6% of emissions tied to public transportation could be avoided across seven high emission countries if similar green initiatives were to be implemented over the 2020-2030 period. This project was carried out with the support of the Sustainable Digital Finance Alliance and UNEP Inquiry.
