Public environmental awareness (PEA) is critical to the implementation of environmental policies by governments and product strategies by companies, however, there is less literature discussing its drivers. Environmental information disclosure (EID), as a bottom-up environmental policy, promotes public environmental management. This paper takes the Pollution Information Transparency Index (PITI) as a proxy for the degree of EID and discusses its impact on PEA. Using the PITI of 113 cities and the Baidu index-based PEA for 30 provinces from 2010 to 2019, we find a significant increase in PEA with the widening of EID, and the impacts of EID get larger as the quantile increases. Moreover, the effects of EID on PEA are amplified in areas with heavy pollution, high levels of green innovation, and stringent environmental governance capacities, but are diminished in areas with rampant corruption. The findings of this paper provide recommendations for optimizing EID implementation. • With the expansion of EID, PEA has increased significantly. • The impacts of EID on PEA are amplified in areas with high pollution, green innovation, and strict governance capacities. • The impacts of EID on PEA are diminished in areas with rampant corruption.
