Carbon Emissions 碳排放
As discussed in Chapter 4: Integrative Process, Planning, and Assessments, greenhouse gas (GHG) emissions (also known as carbon emissions) are gases that trap solar energy (heat) in Earth’s atmosphere and prevent that heat from bouncing back into space. This is called the greenhouse effect, which is where greenhouse gases (GHGs) get their name.
正如第 4 章《整合流程、规划与评估》所述，温室气体（GHG）排放（也称为碳排放）是一类会在地球大气中截留太阳能（热量）、阻止热量反射回太空的气体。这一现象被称为温室效应，温室气体也因此得名。
Burning fossil fuels produces GHG emissions. While there are several types of GHG, carbon dioxide (CO?) is the main contributor to present-day climate change, which is why GHG emissions are also called carbon emissions.
燃烧化石燃料会产生温室气体排放。尽管温室气体包含多种类型，但二氧化碳（CO?）是当前气候变化的主要驱动因素，因此温室气体排放也被称为碳排放。
Green Building Strategies 绿色建筑策略
Green building strategies encourage building decarbonization, the process of reducing or eliminating GHG emissions from buildings. Decarbonization spans multiple areas of green building. For example, reducing transportation-related emissions was discussed in Chapter 5: Location and Transportation. Reducing embodied carbon emissions associated with building materials and construction will be discussed in Chapter 9: Materials and Resources.
绿色建筑策略推动建筑脱碳，即减少或消除建筑温室气体排放的过程。脱碳贯穿绿色建筑的多个领域，例如第 5 章《选址与交通》讨论了减少交通相关排放；第 9 章《材料与资源》将讨论降低建筑材料与施工相关的隐含碳排放。
This current chapter focuses specifically on a building’s operational carbon emissions from its energy use. As with other green building concepts, this requires projects to follow an integrative process. The project team needs to balance energy-related goals with ensuring the project’s energy-related systems can support occupants’ health, protect the project’s durability, and keep it safe and habitable even when the power goes out.
本章重点讨论建筑因能源使用产生的运营碳排放。与其他绿色建筑理念一致，这要求项目遵循整合设计流程。项目团队需平衡能源相关目标，同时确保建筑能源系统可保障使用者健康、保护建筑耐久性，并在断电时仍能维持安全宜居的环境。
