本研究旨在透過問卷調查之方式，探討在不動產生命週期中實現碳中和的可行性和優先次序，並提出相關的減碳政策，以因應全世界氣候變遷的議題，促進台灣不動產業的可持續發展。根據問卷調查顯示，不同群體對於不動產生命週期碳中和的共識較高。不動產業者、建商業者、代銷業者和專家學者等都認為原料生產和建造過程是重要的減碳項目，並以其中之砂石和木材等原料的生產以及材料運輸和建造方式被認為是最重要的影響因素。此外，代銷業者對於銷售階段中"樣品屋"碳排放的重要性有相當高的關注，值得我國政府未來強化規範。依據本研究結果，在不動產生命週期中實施減碳政策的優先次序上，應優先考慮改善原料生產過程，鼓勵使用環保和可再生材料，強化原料供應鏈的碳監測和管理。而在建造過程階段之政策，則建議促進本地原料生產，減少長距離運輸所帶來的碳排放，並推動節能建築設計和施工標準，同時強化建築工地的碳監測和管理，包括減少施工廢棄物和碳排放。另外，針對銷售使用的樣品屋，則應推廣應用數位科技技術，如VR看房，以提供具節能和環保特點的展示房屋方式。透過本研究的結果，政府將能夠瞭解不動產業界和社會大眾對於減碳策略的看法，並能夠根據各群體的共識和差異性來制定相關政策。這將有助於提高政策的接受度和執行效果，推動永續發展的不動產業，並為實現低碳社會的目標做出貢獻。

This study explores the feasibility and prioritization of achieving carbon neutrality across the real estate life cycle through a questionnaire-based investigation, aiming to propose relevant carbon reduction policies to address global climate change and promote the sustainable development of Taiwan’s real estate industry. The survey results reveal a high level of consensus among different stakeholder groups on the importance of carbon neutrality in the real estate life cycle. Industry practitioners, developers, brokers, and academics identified raw material production and the construction process as critical areas for carbon reduction, with sand and timber production, material transportation, and construction methods being deemed the most influential factors. Additionally, brokers expressed significant concern over the carbon emissions associated with "model homes" during the promotion stage, suggesting that stricter regulations on this area are necessary. The study recommends prioritizing the improvement of raw material production processes by encouraging the use of eco-friendly and renewable materials and strengthening carbon monitoring and management within the supply chain. For the construction phase, policies should promote the use of locally sourced materials to reduce carbon emissions from long-distance transportation and advocate for energy-efficient building designs and construction standards while enhancing carbon monitoring and waste management at construction sites. Regarding model homes in the sales stage, the adoption of digital technologies such as virtual reality (VR) tours is proposed to provide energy-efficient and environmentally friendly alternatives for property showcasing. The findings of this study offer valuable insights for policymakers to understand the perspectives of the real estate industry and the public on carbon reduction strategies, enabling the formulation of policies that align with the consensus and variations among stakeholder groups. Such an approach could enhance the acceptance and effectiveness of policies, advance the sustainable development of the real estate sector, and contribute to achieving the goal of a low-carbon society.
