Lights out this weekend! If we organized and each took part in small climate actions the effects could be massive. That’s the sentiment behind Earth Hour — a movement to catalyze global climate action. It might seem silly but the movement has seen some major wins over the years:
💡 In 2007, 2.2 million people turned off their lights for one hour to show Australia’s government that people were concerned about climate change. (That number jumped to 50 million the following year!)
🌊 In 2013, Earth Hour helped lead to the creation of Argentina’s largest marine protected area, the 3.4 million hectare Banco Namuncurá (Burdwood Bank), tripling the area of protected waters in the country.
🪸 In 2018, Earth Hour helped inspire public pressure that led to 5 million sq km of its Exclusive Economic Zone in the South Pacific being classified as a Managed Marine Area – helping preserve vital marine ecosystems for present and future generations.
Earth Hour is Saturday, March 23rd, 2024.

Climate risk is reshaping the real‑estate and construction sectors, forcing a new focus on environmental sustainability in construction. With 2025 marked as the second‑hottest year on record, the carbon footprint of construction is becoming a core business concern. Investors are reassessing portfolios based on resilience, while developers integrate whole life carbon assessment and lifecycle assessment to quantify performance beyond operational efficiency. The demand for low carbon construction materials and eco‑design for buildings is accelerating as decarbonising the built environment becomes a financial imperative.
A proposed 93‑mile hydrogen backbone linking Humber industry to Nottinghamshire could transform supply chains for steel, chemical, and brick production. By cutting dependence on fossil gas, it offers a credible path to low embodied carbon materials. Reductions in embodied carbon in materials will support net zero whole life carbon targets, enabling clients to make procurement choices grounded in life cycle cost and verified by environmental product declarations (EPDs).
The circular economy in construction is moving from concept to contract. Decommissioned wind‑turbine blades are being reused as structural elements in public‑realm projects, signalling genuine end‑of‑life reuse in construction. This form of circular construction strategy supports resource efficiency in construction, substituting waste for raw inputs, and aligns with sustainable material specification standards seen in BREEAM and BREEAM v7 frameworks.
The UK’s narrow planting window threatens both long‑term timber supply and its role in sustainable building design. Without decisive afforestation, claims of net zero carbon buildings and carbon neutral construction may weaken. Provenance data and building lifecycle performance verification are now central to credible sustainable building practices.
The industry faces a decisive test: integrate whole life carbon principles, apply life cycle thinking in construction, and commit to sustainable design that secures resilience under hotter baselines. Those aligning green construction and low carbon design with robust stress testing and sustainable urban development metrics will define the next generation of energy‑efficient buildings and green building materials. The market is already pricing in readiness for a fully sustainable construction future.
