From the rainforests of Central and South America to the savannas of northern Australia, the world's equatorial regions are home to thousands of unique bird species, from macaws to toucans to hummingbirds, who thrive in hot and humid environments. But as climate change accelerates, tropical regions are seeing ten times the number of dangerously hot days than they did 40 years ago, threatening the survival of some of the world's most colorful birds, new research shows. The notion that bird populations are steeply declining is not new – a 2019 study found bird populations in the US and Canada have dropped by 30% since 1970, signifying a loss of almost 3 billion birds. However, much of this loss has been attributed to more direct human impacts, such as habitat loss from farming, logging and mining, or even building collisions. The study underscores the threat extreme heat poses to birds in tropical regions and helps explain why birds are dying even in remote and protected areas, typically considered havens of biodiversity.

Sustainable construction is transitioning from concept to systemic implementation, where water management, land scarcity and resource efficiency are dictating the principles of sustainable building design. Developers across the US Mountain West are applying whole life carbon assessment and lifecycle assessment methodologies to guide construction that reflects environmental sustainability in construction practice. These models prioritise embodied carbon reduction, low carbon design and life cycle cost optimisation to enhance building lifecycle performance and ensure projects achieve measurable sustainability outcomes.

Corporate redevelopment pipelines are shifting toward net zero carbon buildings, integrating eco‑design for buildings and sustainable building practices that embed resource efficiency in construction processes. The large‑scale modernisation of major technology campuses demonstrates that sustainable architecture informed by whole life carbon and embodied carbon in materials can deliver both operational excellence and long‑term value. Strategic procurement of renewable building materials and implementation of low embodied carbon materials are reinforcing circular economy in construction models that support carbon footprint reduction and circular construction strategies.

The housing sector is adopting sustainable material specification principles, with mixed‑income and high‑performance developments achieving BREEAM and BREEAM v7 standards while addressing whole life performance. Such schemes align with life cycle thinking in construction, proving that environmental product declarations (EPDs) and low carbon building methods can achieve both affordability and environmental credibility.

Post‑disaster rebuilding efforts in Indian townships are revealing the cost-effectiveness of nature‑based planning and green infrastructure compared to reactive reconstruction. Investments in eco‑friendly construction are highlighting that resilience demands integration of circular economy principles and decarbonising the built environment.

Amid uneven global decarbonisation, supply chains are evolving to accommodate low carbon construction materials and net zero whole life carbon benchmarks. The most competitive teams are uniting green construction and sustainable urban development approaches that measure the environmental impact of construction and demonstrate continual carbon footprint of construction reduction. By embedding circular economy frameworks into the design, delivery and end‑of‑life reuse in construction, the sector is progressing toward authentic carbon neutral construction and a built environment driven by sustainability and long‑term performance.
