| dc.description.abstract | Due to the consensus of the government and international greenhouse gas emission reductions, many companies have independently checked their own greenhouse gas emissions and planned and implemented emission reductions. Domestic enterprises mainly conduct inquiries in accordance with the guidelines for greenhouse gas inventory and registration announced by the Environmental Protection Agency based on ISO-14064-1,but there is no systematic approach to the investigation, and all the participating process operations, components and factors are considered. Defining an executable reduction method. Therefore, this study developed a system approach for ISO-14064-1 and considered a life cycle assessment for a printed circuit board factory inventory, and developed a reduction measure for major emission targets. This study applies systematic concepts and principles to analyze and define the manufacturing process in a systematic way. First, define the products produced by the manufacturing process, analyze the composition and structure of the manufacturing process, and then analyze the input, output, operating procedures and mechanism of each component, and gradually analyze the possible generation of greenhouse gas emission sources during the operation of the manufacturing process. Introduce life cycle assessment analysis, and conduct process greenhouse gas emission source survey for printed circuit board manufacturing from the acquisition, manufacture, use, recycling, and disposal of raw materials,and for a large number of greenhouse gas emission sources, specific implementation of the reduction measures, the research results show that the system method established in this study to check the proposed greenhouse gas reduction measures, can effectively reduce greenhouse gas emissions, prove that the method established in this study is correct of. | en_US |
