建筑环境既处于气候挑战的中心——建筑目前仍占全球温室气体排放的约 37%——也是解决问题的关键所在。材料和施工工艺在本行业的前期碳影响中占很大比重，而在设计阶段识别出的碳减排只有在其得以延续下来时才具有关键作用
The built environment is both at the center of the climate challenge, with buildings still accounting for about 37% of global greenhouse gas emissions, and essential to its solution. Materials and construction processes represent a major share of the sector's upfront carbon impact, and carbon reductions identified during design are only pivotal if they survive
