為減緩溫室效應所造成的氣候變遷，聯合國於2015通過巴黎協定，戮力控制全球升溫不超過1.5度C。為達成此目標，世界各國近年來紛紛宣示淨零碳排（碳中和）行動並推動淨零排放立法，包含美國、日本、韓國、歐盟等皆以2050淨零碳排為目標。2022年我國的國家發展委員會亦發佈「台灣2050淨零路徑及策略」，具體宣告了淨零碳排的時程，並由內政部主責「淨零建築」路徑規劃及推動，訂出2050目標為100%新建建築物及超過85%建築物為近零碳建築。
依據2021年國際能源署的報告顯示，全球溫室氣體排放，建築部門約占38%，從建築物的全生命週期碳足跡裡分析，其中建築物能源使用部分的「使用碳排」約占28%，建材製造運輸與施工的「蘊含碳排」約占10%。內政部將依據當前國際最新的建築全生命週期碳足跡評估標準建立雙軌制度分別進行納管，首先2022年建立了建築能效標示制度，將「使用碳排」納入評估，2023年將接續建立低蘊含碳建築評估制度，將「蘊含碳排」納入評估。後續將利用雙軌制度成為我國建築達到淨零的量化指標。期許我國營建產業在碳排評估的雙軌制度之下，在設計階段就做好低碳的決策，才是落實碳排減量的具體有效之策。
本年度計畫依據內政部準備推動之「低碳(低蘊含碳)」評估系統，其中之低碳循環建材與低碳工法之認定原則輔導廠商進行試辦，並評估預鑄工法之減碳效益進行分析，期能透過本案辦理評估與認證之試辦作業過程中，提供「蘊含碳排」評估系統更多的參考建議。

Abstract
In order to slow down the climate change caused by the greenhouse effect, the United Nations adopted the Paris Agreement in 2015, striving to control the global temperature rise to no more than 1.5 celsiosdegrees. In order to achieve this goal, countries around the world have announced net-zero carbon emission (carbon neutral) actions and promoted net-zero emission legislation in recent years, including the United States, Japan, South Korea, and the European Union, all of which have set the goal of net-zero carbon emission by 2050. In 2022, my country's National Development Council also released the "Taiwan 2050 Net Zero Pathway and Strategy", which specifically announced the timetable for net zero carbon emissions, and the Ministry of the Interior is responsible for the planning and promotion of the "Net Zero Building" path, setting the 2050 goal 100% new buildings and more than 85% buildings are near zero carbon buildings.
According to the report of the International Energy Agency in 2021, the construction sector accounts for about 38% of global greenhouse gas emissions. From the analysis of the carbon footprint of the entire life cycle of buildings, the "used carbon emissions" of the energy use of buildings account for about 28%. , The “contained carbon emissions” of building materials manufacturing, transportation and construction account for about 10%. The Ministry of the Interior will establish a dual-track system based on the latest international assessment standards for the full life cycle carbon footprint of buildings to manage them separately. First, a building energy efficiency rating system will be established in 2022, which will include "operation carbon emissions" in the assessment. In 2023, it will continue to establish a low-impact The carbon building assessment system incorporates " Low Embodied-carbon carbon emissions" into the assessment. In the future, the dual-track system will be used to become a quantitative indicator for my country's buildings sector to reach net zero goal. It is expected that my country's construction industry will make low-carbon decisions at the design stage under the dual-track system of carbon emission assessment, which is a concrete and effective strategy for implementing carbon emission reductions.
This year's plan is based on the "Carbon Emissions Contained" assessment system that the Ministry of the Interior is preparing to promote. Among them, the principles of low-carbon recycling building materials and low-carbon construction methods are used to guide manufacturers to carry out trial operations, and to evaluate the carbon reduction benefits of the prefabrication construction method for analysis. It is hoped that through During the trial operation process of evaluation and certification in this case, more reference suggestions for the evaluation system of " Low Embodied-carbon carbon emissions" are provided.
