建筑环境脱碳
To meet the Paris Agreement objectives and limit global warming to 1.与工业化前水平相比减少5℃, we must halve 排放 from the built environment by 2030 and fully decarbonize it by 2050. This can only be accomplished through collaboration along the whole value chain. Our Decarbonization workstream helps companies bring about the system transformation required by developing tools, 联盟和共同语言.
所面临的挑战
The built environment is currently responsible for almost 40% of global energy and process-related CO2 排放. 实现全系统脱碳, we need to ensure each company focuses not only on its own emission reduction but also on how they can actively support an overall net-zero transition of buildings. Central to these efforts is achieving net zero for entire buildings across their full life cycle, rather than a siloed approach that detaches products in the system from one another.
商业案例
To decarbonize the building system in line with the Paris Agreement, we need a low-carbon business vision and joint action. This workstream offers a platform for multi-stakeholder collaboration that can accelerate the delivery of solutions for achieving net-zero 排放 over the lifetime of built structures. The opportunity for businesses lies in developing, disseminating and sharing solutions and best practices.
解决方案
Our Decarbonization workstream drives alignment and gathers best practices on net-zero solutions in the buildings and construction sector. We bring companies together to overcome value chain fragmentation and to engage with policymakers, 金融与公民社会. 在一起, we advocate for actions and policies supporting market transformation toward a net-zero built environment. To reduce total life-cycle 排放 of buildings, 我们制定指导方针, 指标, and a common language that can serve as a base for decision-making and collaboration.
在此背景下，我们开发了 建筑系统碳框架. The Framework is an assessment tool representing the carbon 排放 in the buildings and construction system. It helps companies understand where 排放 occur all along the value chain and how they can work together to reduce them through a whole life-cycle approach. The Framework informs all further work to help companies collaborate and to use the influence of demand-side players, 比如开发人员, investors and tenants to drive requirements for a Paris-aligned built environment.
Conduct whole life carbon assessments of your building projects
WBCSD calls on the construction industry to adopt a whole life-cycle approach to assessing greenhouse gas (GHG) 排放 from buildings. The built environment accounts for close to 40% of all energy-related GHG 排放 each year. We must halve these 排放 by 2030 to reach the climate targets of the Paris Agreement.
A key challenge for the industry on its path to net zero is that most building projects do not currently calculate and report their full carbon footprint. We need to understand the whole life carbon (WLC) impact of each building delivered by assessing 排放 throughout the life cycle, from materials manufacturing to the demolition phase. This will allow us to set clear targets and drive carbon 排放 reduction, as shown in our report “Net-zero buildings – Where do we stand?”.
为了支持这些努力, we are collecting WLC case studies from companies to create a body of evidence and foster shared learning. We call on stakeholders from across the built environment to conduct WLC assessments of their building projects and openly publish the results.
To participate in our case study collection, please send us WLC data from a building of your choice. Learn more about how to get involved by clicking on the icons below.
