Global sea level saw a big jump from 2022 to 2023 due in part to a switch between La Niña and El Niño conditions. A mild La Niña from 2021 to 2022 resulted in a lower-than-expected rise in sea level. A strong El Niño in 2023 helped boost the average amount of rise in sea surface height.
Seasonal or periodic climate phenomena can affect global average sea level from year to year. But the underlying trend for more than three decades has been increasing ocean heights as a direct response to global warming due to the excessive heat trapped by greenhouse gases in Earth’s atmosphere.
With more than 30 years of satellite observations, the data show that global average sea level has risen about 4 inches (9.4 centimeters) since 1993 and the rate of increase has more than doubled.

Video Description:
In the center is an animated graph of Global Sea Level Rise from 1993 to 2023. On the X-axis are months January to December. The Y-axis goes from 0 centimeters to 10 centimeters.
0-0:07: As the years tick by at the top of the graph, lines of different shades of blue are added to the graph. Each new line appears above the last one graphed. The lines all have a similar smooth shape, with a slight bump around October.
0:08-0:10: The lines that were graphed all rotate together to form one single line. The line is jagged and trends upward. The months on the x-axis are swapped for the years 1990-2025. The y-axis remains the same.
Efforts to decarbonise the built environment are advancing rapidly as sustainable construction moves from aspiration to measurable action. In London, AHMM’s approved retrofit of Singer Studios in Shoreditch highlights the shift from demolition to adaptive reuse, placing embodied carbon and whole life carbon assessment at the centre of decision‑making. The approach prioritises retaining existing materials and structure to mitigate the carbon footprint of construction while demonstrating that sustainable building design can coexist with architectural quality. The project reinforces industry awareness of the need to quantify whole life carbon and deliver low carbon design consistent with the UK’s commitment to net zero whole life carbon standards.
Water resilience has emerged as a core element of sustainable urban development. ACO Technologies has issued new planning guidance urging local authorities to integrate green infrastructure and sustainable drainage systems into their urban frameworks. The recommendation aligns with broader principles of environmental sustainability in construction, promoting circular economy thinking and life cycle cost analysis of infrastructure. Embedding resource efficiency in construction through sustainable building practices reduces operational carbon while strengthening resilience against intensifying weather extremes across the UK.
At the policy level, the Science Based Targets initiative has begun consulting on guidelines that link land‑use emissions with construction‑related activity. This development points to increasing recognition of the environmental impact of construction on biodiversity and soil health and calls for life cycle thinking in construction that extends beyond the boundary of the site itself. Integrating lifecycle assessment and environmental product declarations (EPDs) into regulatory frameworks is becoming essential for evaluating embodied carbon in materials and reinforcing accountability in sustainable design certification, including future updates such as BREEAM v7.
Technological innovation continues to redefine what sustainable construction can achieve. Carbon Clean’s project in India—converting captured CO₂ into methanol—illustrates the potential for circular economy in construction and the pathway towards low carbon building materials. Similar processes could transform waste emissions into ingredients for green building materials and renewable building products. Such eco‑friendly construction methods exemplify low‑impact construction and carbon neutral construction principles, reducing the embodied carbon of concrete, cement and aggregates while fostering a market for low embodied carbon materials.
Corporate sustainability strategies are evolving alongside these technical shifts. KPMG’s recent ESG findings show that major firms in the built environment sector are increasingly adopting sustainability metrics, linking whole life carbon performance to long‑term business value. Digital tools such as AI are being applied to model building lifecycle performance and optimise life cycle cost outcomes, but genuine transformation depends on transparent whole life carbon assessment and sustainable material specification. The UK government’s revised procurement framework, emphasising social value, may drive greater uptake of eco‑design for buildings and reinforce the transition toward net zero carbon buildings. Whether through regulation or innovation, the success of sustainable architecture will hinge on maintaining measurable progress toward reducing the carbon footprint of construction and embedding a culture of continuous improvement across the lifecycle of every building.
