The product of carbon footprint calculation and carbon labeling does great help to both producers and consumers. For example, producers can look for possible carbon reduction space from each stage of the product life cycle, while consumers can choose to buy environmentally friendly products based on the carbon labeling of products, and understand the impact of daily consumption behavior on the environment. In order to meet the current industrial needs of ceiling fans, this study takes an AC ceiling fan as a baseline to conduct an inventory and analysis of the carbon footprint of ceiling fan products, understand the greenhouse gas emissions of each stage of the product life cycle, so as to know the reduction of the product's carbon footprint. Not only had to find the key factor of decrease carbon but also refined the design and development of ceiling fan products.
