Last year was the hottest year in NASA’s temperature record, GISTEMP. Overall, the 2023 temperature anomaly was 1.17 C (2.1 F) – meaning temperatures last this year were that much higher than the 1951-1980 average.
NASA’s record calculates temperature anomalies, rather than absolute temperatures, to account for imprecision in measurements worldwide. Our record is calculated from millions of measurements from thousands of weather stations, ships and ocean buoys, and Antarctic research stations.
While it would be great to have the same exact thermometer all over the world processing the data in the same exact way, we don’t. Instead we focus on how much warmer or colder the temperatures are in each place based on their own scales.
Plus, since we’re comparing temperatures all around the globe, it wouldn’t make sense to compare temperatures in sunny Bermuda to the cold of Greenland and average them together. Instead, we compare the change in temperatures in Bermuda to the change in temperatures in Greenland, which allows us to track how temperatures are changing worldwide.
NASA’s record is one of many kept by other organizations in the U.S. and globally. @NOAA also found that 2023 was the hottest on record. Despite small differences in data collection and processing, these global records all agree: Earth is warming at an unprecedented rate.

Efforts to decarbonise the built environment are accelerating as UK firms drive forward sustainable construction strategies anchored in measurable environmental performance. Premier Foods’ £2.1 million solar installation at its South Yorkshire bakery exemplifies how low carbon design and renewable energy integration can reshape industrial operations. Generating 20 per cent of the facility’s power, the 2.2 MW system underscores a shift toward net zero carbon buildings, where life cycle cost and whole life carbon assessment increasingly determine investment decisions. This kind of eco-design for buildings reflects a practical model for reducing the carbon footprint of construction while improving resilience within corporate net zero whole life carbon pathways.
The UK government’s newly issued Carbon Budget and Growth Delivery Plan reinforces national intent to achieve environmental sustainability in construction, yet trade leaders warn that barriers to private investment persist. Without financial frameworks that recognise embodied carbon and reward low carbon construction materials, British contractors risk losing competitiveness in the global green construction race. Reforming procurement to include lifecycle assessment metrics, including embodied carbon in materials and energy-efficient buildings performance, could unlock faster adoption of circular construction strategies and accelerate progress toward carbon neutral construction targets.
Policy friction is visible across the regions. The decision by the Scottish Environment Protection Agency to postpone its landfill ban until 2028 highlights persistent challenges in applying circular economy principles to the waste-intensive construction sector. Stronger regulation that promotes end-of-life reuse in construction and low-impact construction could address both waste reduction and resource efficiency in construction. Embedding life cycle thinking in construction will ensure that sustainable building practices align with environmental product declarations (EPDs) and support a functioning circular economy in construction.
At the global level, construction’s share of energy-related emissions remains a defining challenge for climate policy. The UNFCCC has confirmed that current pledges fall short of keeping temperature rises below 1.5ºC, making decarbonising the built environment a pressing priority. Sustainable building design and sustainable urban development must extend beyond design rhetoric into measurable performance standards such as BREEAM and BREEAM v7 certification, which quantify building lifecycle performance and encourage renewable building materials. These tools convert sustainable design goals into verifiable environmental impact of construction outcomes, improving the credibility of sustainability reporting worldwide.
Recent research suggests UK organisations are leading Europe in sustainable architecture and sustainable material specification, though disconnects persist between strategic ambition and practical implementation. Bridging this credibility gap demands a greater emphasis on whole life carbon, embodied carbon metrics, and transparent lifecycle assessment to guide next-generation eco-friendly construction. As firms adopt green building materials and invest in green infrastructure, the sector edges closer to a future defined by low carbon building solutions and genuine carbon footprint reduction—a necessary foundation for a resilient, resource-efficient, and truly sustainable construction economy.
