Abstract: With global warming becoming a hot spot of social attention,carbon footprint becomes a new research method and quickly gets the attention of academia.However,there are few researches on the indirect emissions besides electric power and heat consumption in the list of carbon footprint.Equipment investment accounts for about 55% of the total investment of new coal chemical industry projects,but the indirect CO₂ emissions caused by equipment depreciation has not been taken into consideration.Taken new coal chemical products as examples,the influences of fixed assets depreciation on carbon footprint of new coal chemical products were discussed.It was put forward that the depreciation of fixed assets was an important source of new coal chemical products carbon footprint,and should be attached great importance in future research.
