Development of a Board Game as a Learning Tool to Promote Household Actions Toward Net-Zero Carbon Emissions

Addressing climate change requires increased individual awareness and behavioral change. This study aims to encourage lifestyle transformation by illustrating how everyday behaviors influence CO2 emissions and future outcomes. To this end, a board game was developed to help players learn about the potential CO2 reduction effects of their daily choices. Through gameplay, participants recognize the impacts of various CO2-reducing actions and the significance of their cumulative effects. A workshop involving approximately 170 elementary and junior high school students confirmed behavioral changes among participants, demonstrating the effectiveness of the game.
