Impact of psychological distance on public acceptance of waste-to-energy combustion projects

Waste-to-energy (WTE) projects have attracted considerable attention due to their role in addressing waste management issues and promoting renewable energy production. However, while public acceptance of these projects remains controversial, psychological distance (PD) may be a key shaping factor in their construction. This study, grounded in the Construal Level Theory (CLT) and social distance theory of power, uses a behavioral investigation experiment to examine the role of PD in WTE facilities. The findings reveal that shorter PD is associated with higher public perception of risk and lower perception of economic benefits, fairness, and public acceptance. Additionally, a closer social distance of power tends to correspond with lower construal levels and a greater inclination to support the construction of WTE facilities, further supporting the CLT and social distance theory of power. The findings provide theoretical support and practical guidance for the sustainable development of WTE facilities, encouraging a sense of shared destiny and collaborative governance across society.
