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.
The sustainable construction agenda is shifting from ambition to delivery as power policy, climate risk and material accountability reshape the built environment. In the UK, calls for a 2035 electrification target are intensifying scrutiny of heat pumps, solar, batteries and the infrastructure needed to move buildings away from fossil fuels. The Future Homes Standard is pushing sustainable building design beyond compliance, with energy-efficient buildings, low carbon design and net zero carbon buildings becoming central to housing delivery, roofing, flooring and building services.
Whole life carbon is now the critical measure for environmental sustainability in construction. Developers, designers and contractors are under growing pressure to use whole life carbon assessment, lifecycle assessment and life cycle cost analysis to prove building lifecycle performance, not just operational efficiency. Embodied carbon, embodied carbon in materials and the carbon footprint of construction are moving up the procurement agenda, increasing demand for low embodied carbon materials, low carbon construction materials, renewable building materials, green building products and robust environmental product declarations (EPDs).
The global energy outlook strengthens the case for low carbon building and net zero carbon strategies. Forecasts of a 4,800GW rise in renewable capacity by 2035 indicate that cleaner electricity will increasingly support eco-design for buildings, sustainable architecture and carbon footprint reduction. China’s clean-tech exports are reshaping supply chains and costs, while its emissions profile reinforces the need for credible plans to retire fossil fuels rather than rely on electrification alone.
Climate adaptation is becoming a core test of sustainable building practices. The £5m flood defence scheme at Severn Stoke reflects rising demand for green infrastructure and resilient sustainable urban development as flooding, heat and drought become more severe. Research warning that climate impacts could weaken societies’ ability to decarbonise highlights the industry’s dual challenge: decarbonising the built environment while designing assets capable of withstanding climate disruption.
Materials policy is set to become a decisive battleground. Scotland’s review of waste laws points towards stronger circular economy in construction, greater resource efficiency in construction and more rigorous end-of-life reuse in construction. Circular construction strategies, sustainable material specification and life cycle thinking in construction are becoming essential to net zero whole life carbon outcomes. Standards such as BREEAM and BREEAM v7 are likely to gain importance as clients seek clearer evidence of green construction, eco-friendly construction, low-impact construction and carbon neutral construction. Sustainable construction is no longer judged by declarations of sustainability, but by verified performance across energy, materials, resilience and the full environmental impact of construction.
