The research is conducted in Pakistan's context, while future studies need to be conducted in other emerging economies to investigate the linkage between CSR, firm reputation and performance.Originality/valueAccording to the researcher's best knowledge, very few studies have been conducted regarding the relationship between environmental awareness, green practices, firm reputation and performance in emerging economies like Pakistan.
