Abstract: Based on the general principles of international standards and the standard system of carbon emission accounting based on products, and the production practice of low-emission prebaked anode petroleum coke in domestic refining and chemical enterprises, the life cycle assessment template of this product was established, the circular reference relationship was established, the energy consumption and carbon emission inventory of each link were analyzed, and the carbon footprint from cradle to gate was calculated and quantified to be 380.1 kgCO₂e/t.. Based on the carbon emission accounting of this product, the principles and guidelines of life cycle carbon emission assessment and the exploration and research of quantitative methodology are completed.

Key words: carbon footprint, prebaked anode, petroleum coke, life cycle
