There isn't much green in the Sahara Desert, but after an unusual influx of rain, the color can be seen from space creeping into parts of one of the driest places in the world. Satellites recently captured plant life blooming in parts of the typically arid southern Sahara after storms moved there when they shouldn't. It has also caused catastrophic flooding. And scientists say a world warming due to fossil fuel pollution is making both more likely. Rainfall north of the equator in Africa typically increases from July through September as the West African Monsoon kicks into gear. But since at least mid-July, this zone has shifted farther north than it typically should, sending storms into the southern Sahara, including portions of Niger, Chad, Sudan and even as far north as Libya, according to data from NOAA's Climate Prediction Center. As a result, these portions of the Sahara Desert are anywhere from twice as wet to more than six times wetter than they should be. Read more at the link in our bio. 📷: CIRA/RAMMB

Regulatory momentum across the built environment is tightening as governments and industry bodies align around robust frameworks for decarbonising construction. The EU’s reform of carbon market controls aims to maintain strong carbon price signals to advance whole life carbon reduction, while ISO’s new standard on net‑zero transition plans gives investors and contractors a consistent structure for measuring life cycle cost and performance. The Science Based Targets initiative is establishing clearer boundaries between verifiable net zero carbon buildings and unsubstantiated claims, driving greater transparency in embodied carbon reporting and lifecycle assessment within construction supply chains.

Engineering progress is translating policy ambition into practice. Plans for a large‑scale direct air capture plant on Teesside highlight a new model of carbon neutral construction industry in the UK, pairing heavy engineering expertise with circular economy principles. Expansion of natural fibre insulation and low embodied carbon materials into mainstream housing retrofits demonstrates eco‑design for buildings moving beyond pilot projects. Sustainable construction now depends on accurate whole life carbon assessment and the specification of renewable building materials validated through environmental product declarations (EPDs).

Climate resilience is reshaping valuation and insurance models as climate‑driven subsidence data sharpen awareness of the environmental impact of construction. Developers are applying sustainable building design and low carbon design strategies to manage soil instability and resource efficiency in construction projects. The focus on whole life carbon and embodied carbon in materials signals a maturing market where green construction and sustainable building practices are metrics of competitiveness, not aspiration. Standards such as BREEAM v7 reinforce this shift toward lifecycle performance, end‑of‑life reuse in construction and circular construction strategies that define the next phase of environmental sustainability in construction.
