People in urban areas are at higher risk during heat waves, but NASA data shows how parks and green spaces are cooler than the surrounding areas. This image shows how asphalt and concrete trap heat. The purple and red areas are surfaces that are hotter than 130℉ (54℃). Yellow areas are slightly cooler but still very hot. Some roads and sidewalks got so hot that a few seconds of skin contact could result in second degree burns. This image shows mid-day conditions in Phoenix, AZ on June 19, 2024. It was measured by a NASA instrument called ECOSTRESS, which is aboard the @iss. Data from Landsat and Sentinel-2 helped improve the resolution so that differences can be seen across a smaller area. Information like this can help people and communities plan ways to stay safer in the heat. Image Descriptions: 1: Text reads “Urban Heat Seen From Space” in white at the center of the image with a yellow, red, and purple bar underneath. In the background is a map of urban heat risk in Phoenix. 2: A map of the Phoenix area, where asphalt and concrete surfaces are outlined in yellow, red, or purple lines depending on the surface temperature. Purple represents the hottest. The left side of the image is mostly purple and the right side is mostly red. Several park areas and green spaces have yellow (cooler) surface temperatures. A key at the bottom of the image correlates color to surface temperature and thermal burn risk. 3: The same map of the Phoenix area, but zoomed in over Encanto to highlight areas around green spaces, which are mostly yellow. #Earth #NASA #Climate #Data #Heat #Science

Climate resilience and adaptation have become critical in the UK, with the Climate Change Committee highlighting underinvestment in infrastructure and limited progress on whole life carbon reduction. The urgency shapes the path forward for sustainable construction, pushing the sector to integrate whole life carbon assessment, embodied carbon reduction, and life cycle cost optimisation into robust infrastructure and sustainable building design. A national focus on environmental sustainability in construction is essential for future economic stability and long-term environmental outcomes.

Major initiatives reflect this shift. Morgan Sindall Construction is leading regeneration of Bideford waterfront, expected to incorporate circular economy strategies. Policy proposals such as expanding the Boiler Upgrade Scheme offer incentives for low carbon building upgrades, aiming to reduce both operational carbon and the embodied carbon in materials across the built environment. These moves demonstrate the construction industry’s growing commitment to net zero whole life carbon targets and sustainable urban development.

Guidance for carbon reduction has advanced, with the Voluntary Carbon Markets Integrity Initiative introducing frameworks to better manage corporate Scope 3 emissions and support more credible whole life carbon and lifecycle assessment strategies. This is vital for large firms shaping the carbon footprint of construction, encouraging broader adoption of circular economy in construction and sustainable material specification across portfolios.

Digital innovation is increasingly essential. Vodafone’s partnership with UK National Parks uses real-time data to inform resource efficiency in construction, providing new tools for building lifecycle performance and supporting environmental impact reduction. These technologies empower stakeholders to manage the carbon footprint and environmental sustainability in construction, aligning project delivery with net zero carbon buildings and circular construction strategies.

Scrutiny on environmental claims is intensifying. A recent ruling by the UK Advertising Standards Authority against misleading compostability claims highlights the need for accurate environmental product declarations (EPDs) and transparency in green building materials. Developers and clients now require trustworthy information about the environmental impact of construction and end-of-life reuse in construction to achieve genuine eco-friendly construction and sustainable building practices.

The landscape for construction is rapidly evolving. Stakeholders are under pressure to decarbonise the built environment by adopting lifecycle thinking in construction, prioritising low embodied carbon materials, and supporting net zero carbon goals. A combination of strong policy, innovative frameworks, and technology-driven solutions offers unprecedented opportunities for sustainable construction worldwide, ensuring the sector stays ahead in the transition to carbon neutral construction and green infrastructure.
