建筑与气候：脱碳和韧性

In March 2024, representatives of 70 countriesgathered in Paris to sign the “Chaillot” Declaration(namedafter the stately building where thesignature took place). The aim was to spur freshprogress toward the decarbonization and climateresilience of buildings, promoting a fast, fair andefficient transition. The global declaration calls foraction in the fields of urban planning, constructionandretrofitting.It invites all stakeholders tocooperate, exchange best practices and sharedata. stronger winds, heavy rains, etc.) to a greaterextent than any other asset class. And thesehazards are set to become more intense as aresult of climate change. A building’s sustainabilitythereforeincreasingly affects its regulatorycompliance, financing, cost of construction andoperations, value and insurance premiums. Beyond regulatory requirements, operationalcost reductions and improved asset value,managing sustainability is the right thing todo. Buildingshave a huge impact on theenvironment.Multiple sources charge thebuilding sector with accounting for overone-third of global energy demand and related CO2emissions. Moreover, demand for constructionmaterials is expected to balloon as urbanizationreaches new heights – more than half the globalpopulation already lives in urban areas and thefigureis rising.Construction,demolition andrenovation projects generate billions of tons ofwaste annually, a significant proportion of whichends up in landfill.
