Carbon Footprint of Product (CFP) means the life cycle greenhouse gas (GHG) emissions of goods and services. CFP is different with organization GHG emissions inventory and reporting based on ISO 14064-1, which is one of the approaches for understanding the GHG emissions across the product’s entire supply chain. Analyzing and understanding these emissions, and where they come from, is necessary in order to reduce the GHG emissions. A product’s lifecycle includes raw materials capturing, product manufacturing, transporting to next manufacturing, distribution/retail, consumer use and disposal/recycling. If a product is not a final product, it is classified as a B2B (business-to-business) goods, consistent with the ‘cradle to gate’ approach described in ISO 14040. A final product is classified as a B2C (business-to-consumer) good, which is consistent with the ‘cradle to grave’ approach described in ISO 14040. For steel industry, most of the products are not supply to end users; therefore, the most are the B2B goods. For China Steel Corporation, all of the products are B2B goods. Reducing the CFP of China Steel Corporation’s products can help the supply chain reducing the greenhouse gas emission in life cycle. Moreover, CFP is a part of life cycle assessment (LCA). We care all the environmental issues, not only climate change. We will keep developing and producing steel products with LCA thinking.
