The #CopernicusEU Climate Change Service (C3S) has published its latest monthly Climate Bulletin, focused on key climate trends in April 2025. 📊
🌡️ The bulletin reports that April 2025 was the second warmest April on record globally, with an average surface air temperature of 14.96°C, 0.60°C above the 1991-2020 average for the month.
Furthermore, April 2025 measured 1.51°C above the pre-industrial average. In Europe, the average temperature for April was 9.38°C, 1.01°C above the 1991-2020 average.
This data visualisation, produced using C3S data, illustrates the surface air temperature anomalies for April 2025 across the Northern Hemisphere. Shades of red indicate areas with above-average temperatures, while blue tones show below-average values.
The intense warm anomalies over parts of western Asia and Scandinavia are particularly notable, as are the cooler conditions observed over Greenland and parts of the northern Atlantic Ocean.

A tightening regulatory and technical landscape is redefining sustainable construction across the UK and beyond. The Building Safety Act is reshaping project governance by requiring transparent reporting and accountability that link safety with environmental sustainability in construction. Compliance processes are driving a shift toward whole life carbon assessment, embedding sustainable building design principles at the earliest design stage and quantifying both operational and embodied carbon.
Digital systems such as the government’s waste‑tracking initiative are enabling circular economy in construction practices, mandating traceable material flows and revealing the carbon footprint of construction through verified lifecycle assessment. These data‑driven mechanisms enhance resource efficiency in construction and reinforce the wider transition to low embodied carbon materials and eco‑friendly construction.
Investment is converging on decarbonisation at scale. A new £120 million waste‑to‑hydrogen facility is designed to transform residual waste into clean fuel, supporting low carbon design and resilient net zero carbon buildings. Growth in grid‑balancing storage improves the stability of renewable‑powered operations, a prerequisite for energy‑efficient buildings and low carbon building performance across portfolios.
Governance frameworks are also advancing. The creation of a dedicated leadership structure for the Greenhouse Gas Protocol elevates global consistency in measuring whole life carbon and encourages transparent benchmarking using environmental product declarations (EPDs). This maturity strengthens sustainable building practices, fosters green construction aligned with BREEAM v7 standards, and supports decarbonising the built environment through life cycle cost and performance management.
The cumulative effect signals a transition to net zero whole life carbon imperatives governed by robust data, certified materials, and measurable outcomes. The progress may appear administrative, yet it represents the essential infrastructure of sustainable material specification, circular construction strategies, and long‑term green infrastructure supporting a truly carbon neutral construction sector.
