價值11.6萬億美元的全球基礎設施行業正在努力建設將為子孫後代提供住房和交通的建築、結構和資產。但是，許多構成建築環境的項目——包括建築、供水和電力係統、道路和橋梁以及交通係統——並沒有按照世界淨零目標進行建設。據麥肯錫估計，建築行業直接或間接造成了全球40%的燃料燃燒產生的二氧化碳排放和25%的溫室氣體排放。1 1。《行動呼籲:抓住建築行業的脫碳機遇》，麥肯錫，2021年7月14日。在本期《聲音》雜誌中，領導者們就如何最好地脫碳我們的建築環境和建立一個可持續的未來提出了自己的觀點。實現淨零排放將是困難的。我們的研究表明，在2050年之前，全世界每年需要投資9.2萬億美元，才能在建築環境中實現淨零排放。然而，這樣做將圍繞綠色商業建築創造許多令人興奮的機會。考慮到這一點，麥肯錫和全球基礎設施投資者協會(GIIA)討論了脫碳的途徑:了解和繪製各行業的排放源，並描述投資組合經理如何提供必要的細節和透明度，以衡量淨零目標的實際進展。 Voices on Infrastructure: Decarbonizing the built environment Indeed, measuring progress, communicating it well, and predicting risk are all critical to success. Gordon Reid and Mark Williams from Scottish Water, Scotland’s national public water and wastewater service, share their insights on how achievable net-zero emissions goals are and how effective high-level strategy can be when it’s communicated properly. And Tariq Taherbhai of global insurer Aon grapples with the question of how to account for project risk effectively, from assessing the risks posed by suppliers and subcontractors to dealing with volatile climatic events in large construction projects. Decarbonizing our built environment will also require the industry to embrace greener construction methods and materials. An article from McKinsey’s Zak Cutler, Taylor Dayton, Matthew Grant, Shu’aib Mahomed, and Jemilat Ojetayo offers a perspective on the importance of reducing embodied emissions—that is, the emissions associated with construction. And we share a summarized overview of a recent report on achieving net-zero emissions in the steel industry, written in collaboration by McKinsey and the Energy Transition Commission. To round out the issue, the fifth and final article in the series by senior adviser Richard Westney and McKinsey’s Capital Excellence team illustrates how doing good demands doing better when it comes to delivering net-zero capital projects. In this case, doing better means establishing a new framework for procurement, engineering, and construction. The article also includes an interview with Greg Lawton, cofounder and CEO of project-delivery company Nodes & Links. We hope you find this issue of Voices insightful as it relates to your own ongoing conversations about how to decarbonize buildings at every scale.
