［Objective/Significance］ As global warming continues to intensify，the conflict between people’s need for cooling and the consumption of sustainable energy is becoming increasinglyapparent. Achieving effective cooling without consuming external energy is of great significance inimproving the living environment and alleviating the energy crisis.［Analysis/Discussion/Progress］ Passive radiative cooling materials can cool themselves without consuming additional energy and areconsidered a relatively ideal method to address the issue of global warming and reduce cooling energyconsumption. According to relevant literature，cellulose acetate exhibits excellent radiative coolingperformance and is environmentally friendly，demonstrating tremendous potential in the field of green radiative cooling coatings.［Conclusion/Prospect］In the future，with in-depth research on the material structures and spectral regulation mechanisms，cellulose acetate-based radiative cooling coating materials are expected to provide more reliable solutions for the field of energy conservation and cooling.
