Using the data from the World Value Survey, this paper uses a comparative lens to assess environmental philanthropy by focusing on four predominantly Chinese societies - mainland China, Taiwan, Hong Kong, and Singapore, which contributes to the debate on whether culture can sufficiently explain cross-regional variation in civic engagement, particularly in the domain of environmental philanthropy. We find that residents in mainland China shared similar environmental concerns and beliefs with people from the other regions, but they are least likely to volunteer, donate, and demonstrate for these causes. After accounting for personal characteristics, the sizeable interregional gaps on pro-environmental behaviors remain. These findings are consistent with the argument that structural differences, particularly the developing nature of civil society in mainland China, hinders environmental civic engagement.
