New data confirms 2024 will be the hottest year on record and the first calendar year to exceed the Paris Agreement threshold — devastating news for the planet that comes as America chooses a president that has promised to undo its climate progress both at home and abroad.
Nearly all the world's countries pledged to strive to keep global warming under 1.5 degrees Celsius in the Paris Agreement, which scientists said would prevent cascading and worsening impacts such as droughts, heat waves and catastrophic sea level rise. They warn at that level, the human-caused climate crisis — fueled by heat-trapping fossil fuel pollution — begins to exceed the ability of humans and the natural world to adapt.
Data released Wednesday by Europe's Copernicus Climate Change Service shows 2024 is "virtually certain" to shoot above that threshold.
President-elect Donald Trump, a noted climate denier, pulled the US out of the Paris Agreement during his first term and has vowed to do it again in his second. But the new data makes it clear further delays in climate action from leading global economies will ensure even higher levels of warming are reached, and with it, ever worsening impacts.

Sustainable construction is shifting from ambition to delivery, with whole life carbon, embodied carbon and life cycle cost now shaping decisions across infrastructure, buildings and climate resilience.
The UK’s Lower Thames Crossing shows the direction of travel, as National Highways works to connect low-carbon plant with dependable hydrogen supply. JCB’s hydrogen combustion route and Toyota’s fuel cell approach point to a maturing market where low carbon design depends as much on refuelling infrastructure as machinery innovation.
Decarbonising the built environment is also moving into operational heat and data. The National Geothermal Centre’s estimate that the UK could unlock 10GW of geothermal heat by 2050 strengthens the case for renewable heat in net zero carbon buildings, provided policy, planning and finance align. In Europe, efforts to make renovation data usable by 2027 underline the importance of lifecycle assessment, building lifecycle performance and whole life carbon assessment. Retrofit programmes need verified information on fabric, energy use, sequencing and embodied carbon in materials if sustainable building design is to move beyond targets.
Climate adaptation is becoming inseparable from environmental sustainability in construction. The £249m Bridgwater Tidal Barrier reflects growing investment in green infrastructure designed for rising water levels and rising project costs. Drought-related subsidence shows that housing resilience must be treated as part of sustainable building practices, not a separate risk category. Extreme heat is already damaging construction productivity, with MSCI estimating labour losses equivalent to around 2% of global GDP.
The sector now faces linked pressures: cleaner construction sites, energy-efficient buildings, low embodied carbon materials and assets capable of withstanding a harsher climate. Copper supply constraints add further complexity to electrification, strengthening the need for resource efficiency in construction, circular economy principles and circular construction strategies. BREEAM, BREEAM v7, environmental product declarations (EPDs), sustainable material specification and eco-design for buildings are becoming practical tools for reducing the carbon footprint of construction and supporting net zero whole life carbon. Sustainability is no longer a procurement preference; it is becoming the core constraint on how construction is planned, financed, built and maintained.
Whole Life Carbon is a platform for the entire construction industry—both in the UK and internationally. We track the latest publications, debates, and events related to whole life guidance and sustainability. If you have any enquiries or opinions to share, please do
