On March 7, organizers of the 2025 Osaka Expo officially launched the EXPO Green Challenge App. Aiming to encourage people to reduce their carbon footprint, the app allows users to earn points for eco-friendly actions.  Donating used cooking oil and carrying personal water bottles instead of buying plastic are among the actions worth points. 

But the app does more than just track users' contributions to reducing greenhouse gas emissions. Users can apply points to enter draws for prizes like tree saplings and portable solar chargers.

Gamifying Decarbonization

The Japan Association for the 2025 World Exposition has made the free smartphone app available. They aim to reach 200,000 downloads by the Expo's opening in April 2025.

A reduction in carbon emissions equivalent of approximately 57,000 tons is the overarching goal. This is the equivalent of the anticipated 28.2 million Expo visitors traveling from JR Osaka Station to the Expo venue in Yumeshima by car.
