实现净零建筑——市场转型的关键行动

Foreword The consensus is that there has to be drastic actionto reduce carbon emissions by 2030 to stay within a1.5°C global warming threshold. And yet, six years out,global built environment emissions are still rising and,in many markets around the world, the policies andincentives to drive the transition to net-zero emissionsbuildings are not yet in place. So how is it possible tourgently accelerate the large-scale transition to net-zerobuildings in the next six years? We reference leading examples from around the worldthat – combined – illustrate what we believe to be theideal route to creating the enabling environment that willdrive the market transformation to a net-zero buildingstock. Whether implemented at a local or national level, the12-Step Action Plan will be most effective if executedthrough close cooperation between policymakersand industry. Driving consistency and transparency ofperformance and enabling the market to react to and, inturn, incentivize net-zero emissions outcomes through itstransactions will require policy levers. As identified in the Market Transformation ActionAgenda, there must be an enabling environment.The market must recognize and reward net-zerobuildings, governments must tax them at a lower rateand financing them must be cheaper. This will makethem more valuable as assets and therefore unlockinvestments in the transition. It's clear that actions in the built environment cannotcontinue at the current pace. We look forward toengaging in a discussion on this proposed 12-Step ActionPlan and to supporting further collaborative efforts todrive change. In this document, we identify four objectives that willhelp create this enabling environment – definition,transparency, minimum performance and incentives.While in most markets around the world these are notyet in place, there are national and local examples ofpolicies, incentives and market mechanisms that haveproven to be effective in driving change. Stephen Hill, Associate Directorand Lead Author, Arup We propose a 12-Step Action Plan to achieve theseobjectives, with interdependent actions that reinforceeach other and that any market can adopt to drivechange.

Context And in March 2024, over 60 countries backedthe Declaration de Chaillot,3committing to theimplementation of long-term sector roadmaps, makingbuilding energy codes mandatory and leading publicprocurement, among other objectives, to accelerate andprogress the decarbonization of buildings. In 2022, the building sector globally was responsible for37% of energy-related carbon emissions (or 21% of totalgreenhouse gas emissions),1of which over two-thirds werefrom the energy consumption of buildings in operation. In recognition of the importance of property sectordecarbonization in the overall fight against climatechange, at the 28th United Nations Climate ChangeConference (COP28) 28 countries joined the BuildingsBreakthrough,2aligning behind the shared goal to ensure The intent is that these commitments lead to thedevelopment of local and national industry standardsand legislation – the instruments that will drivetransformation. But progress towards this is still verylimited in most countries around the world. Globally,despite energy-efficiency improvements, overall propertysector emissions continue to rise,4so there is an urgentneed to accelerate action to drive the transition to net-zero emissions and deliver meaningful decarbonizationacross the sector. Near-zero emissionsand resilientbuildings are thenew normal by 2030. Introduction01. Purpose of this document The role of government Our intention is for collaboration between policymakersand industry to deliver the Action Plan. Experience fromaround the world highlights the key role that nationaland sub-national governments can play in driving thetransition, specifically: Recognizing the urgent need for change, this documentrecommends a cohesive set of clear and specific stepsto shift the market to deliver net-zero buildings at scale. This is consistent with, and part of, the Built EnvironmentMarket Transformation Action Agenda.5Its Intervention5 in particular specifically speaks to this need. This ispart of the broader industry objective to achieve net-zero whole life emissions and has its place alongsidework by WBCSD and others to address full life-cycledecarbonization. →Mandating the transparency of performance, whichimproves understanding and unlocks investment; →Through procurement, testing new and innovativeapproaches in the public sector; →Setting mandatory minimum energy performancestandards, ensuring all buildings are at least on ajourney to net-zero emissions.
