Description

Technical Field

[0001] The present invention relates to the technical field of energy conservation and emission reduction, and in particular to a carbon footprint analysis method and system for fuel heater products based on life cycle assessment. Background Art

[0002] As global warming becomes increasingly serious, governments and businesses around the world are recognizing the importance of carbon emissions control and are actively promoting the implementation of relevant emission reduction measures. Against this backdrop, various industries are taking action to reduce the carbon footprint of their products and services throughout their lifecycles, thereby achieving more sustainable development goals.

[0003] In the industrial and agricultural sectors, the demand for heating large spaces continues to grow with socioeconomic development. Fuel-fired heaters, due to their efficient heating capacity and flexible operation, are widely used in construction sites, warehousing and logistics, agricultural planting, and animal husbandry. As a primary heating device, fuel-fired heaters produce large amounts of carbon dioxide and other greenhouse gases during combustion, which has a significant impact on the environment. However, the current market lacks systematic assessment methods and tools for the carbon emissions of fuel-fired heaters, especially in carbon footprint analysis across different stages of the product life cycle.

[0004] Existing carbon footprint analysis methods usually focus on a specific stage, such as the production process or the use stage, but fail to fully cover the entire life cycle of the product. This method leads to inaccurate estimates of carbon emissions and cannot provide a sufficient scientific basis for low-carbon optimization of products. In addition, the manufacturing process of fuel heaters involves the use of a variety of raw materials (such as plastics, metals, etc.), and the production and processing of these materials also generate a large amount of carbon emissions. However, the industry currently does not fully consider these implicit carbon emissions, which affects the accurate estimation of the overall carbon footprint of the product.

[0005] On the other hand, fuel heaters generate a significant portion of their lifecycle carbon emissions during transportation and use. Fuel consumption during the use phase, in particular, directly determines the device's total carbon emissions. However, existing technologies fail to provide effective methods for optimizing carbon emissions during use, resulting in high carbon emissions during product design and use.

[0006] Therefore, developing a carbon footprint analysis method and system for fuel heaters based on life cycle assessment, covering all life cycle stages, including raw material acquisition, manufacturing, transportation, use, and final disposal, is of great practical significance. This will not only help industry companies more accurately quantify and manage their products' carbon emissions, but also provide a scientific basis for low-carbon optimization in product design, production, and use, thereby promoting the green development of the heating equipment industry and contributing to the country's "dual carbon" goals.
