BUILDINGS & CLIMATE:DECARBONIZATION AND RESILIENCE BUILDINGS AND CLIMATE : DECARBONIZATION AND RESILIENCE 2In March 2024, representatives of 70 countries gathered in Paris to sign the “Chaillot” Declaration (named after the stately building where the signature took place). The aim was to spur fresh progress toward the decarbonization and climate resilience of buildings, promoting a fast, fair and efficient transition. The global declaration calls for action in the fields of urban planning, construction and retrofitting. It invites all stakeholders to cooperate, exchange best practices and share data.Buildings have a huge impact on the environment. Multiple sources charge the building sector with accounting for over one-third of global energy demand and related CO2 emissions. Moreover, demand for construction materials is expected to balloon as urbanization reaches new heights – more than half the global population already lives in urban areas and the figure is rising. Construction, demolition and renovation projects generate billions of tons of waste annually, a significant proportion of which ends up in landfill. Climate change has an important impact on buildings. Buildings are exposed to climate-related hazards (heatwaves, rising sea level, INTRODUCTION– A GLOBAL CHALLENGE stronger winds, heavy rains, etc.) to a greater extent than any other asset class. And these hazards are set to become more intense as a result of climate change. A building’s sustainability therefore increasingly affects its regulatory compliance, financing, cost of construction and operations, value and insurance premiums.Beyond regulatory requirements, operational cost reductions and improved asset value, managing sustainability is the right thing to do.

By 2060, the global footprint of buildings is set to double, with more than 230 billion m² in new constructions!According to the International Energy Agency (IEA), if the sector fails to take significant steps to improve sustainability, CO2 emissions from buildings could increase by 50% by 2050.56% of the world’s population currently lives in urban areas 3At Bureau Veritas, we believe that mutual trust within the industry will be a key ingredient in successful climate change transition and adaptation. This paper presents what we have learned with our clients, our vision of the way forward and the role we intend to play within the industry.BUILDINGS AND CLIMATE : DECARBONIZATION AND RESILIENCE BUILDINGS AND CLIMATE : DECARBONIZATION AND RESILIENCE 4Sustainability
