Photos by @jameswhitlowdelano Interesting pushback to the Heat Island Effect/urban deforestation post using an argument similar to what a Malaysian logging conglomerate might use. Apologies to those who draw offense when facts & evidence get in the way of a good narrative. Image #1: Heat Island Effect: In the midday sun in Tokyo on this July day it is 45.7 C (114.3 F). The Heat Island Effect in Tokyo is exacerbated by urban deforestation. Seijo is in Tokyo's Setagaya Ku (Ward), which has suffered a 34.7% tree cover loss since 2013, according to a University of Tokyo, Department of Natural Environmental Studies research paper, intensifying the heat island effect in urban Tokyo. In "leafy" districts, like Seijo, few trees exceed 3 - 4 meters in height because few houses stand long enough for the trees to reach mature height or the trees are assiduously pruned to avoid shedding leaves, seeds or fruit on neighbors' properties. When a house in Tokyo is demolished, rarely lasting longer than 25 years, the entire property is razed, including removing all trees or shrubs, leaving bare ground. Seijo, Setagaya-Ku, Tokyo, Japan Image# 2: On a treeless street, parallel to this one, in the direct sun, just steps away from this shaded street in Tokyo's Seijo neighborhood, the sun drove the temperature up to 45.7 C (114.3 F). Treelined streets like this one are so rare in Tokyo's Setagayu Ku (Ward), that Seijo is famous for these "sakura" cherry trees. Despite being a blistering 37.5C (99.5 F) under the tree canopy, the temperature drops by 8.1 C (14.6 F) compared to its parallel asphalt neighbor exposed to the punishing rays of the sun. Image#3: When older residential structures, which rarely last more than 25 years in Tokyo, are razed, the property is wiped clean of all trees or shrubs that shaded the ground. Image# 4: The Sengawa (Sen River), which separates Seijo from Soshigaya in Setagaya Ku (ward) in Tokyo, is sealed in concrete. If rivers are not reduced, like this one, to a concrete trough, they are walled or leveed as part of massive flood control projects in this densely-populated, typhoon-prone country. #climatechange #heatislandeffect

A new development in sustainable construction comes as Swedish low-carbon cement is used for the first time in the UK at a warehouse base in Surrey. This marks a significant step in reducing carbon emissions in construction materials, alongside other innovations in low carbon solutions spreading across Europe.

Global technology company Microsoft is innovating its data centers with water-efficient cooling systems. This sustainable approach reduces water usage, aligning with broader green building principles and contributing to more eco-focused urban infrastructure.

Efforts to enhance fuel sustainability are gaining momentum with British Airways' parent company, International Airlines Group, investing in a company focusing on creating aviation fuel from waste tyres. This initiative supports the circular economy by turning waste into valuable resources, a key element in sustainable construction for reducing waste and energy use.

The UK Green Building Council has released a report on trends driving sustainable transformation in the built environment. Highlighting the importance of renewable energy sources, energy efficiency, and innovative building materials, the focus is on reducing the carbon footprint of urban structures and enhancing energy resilience, setting the stage for future sustainable urban development.

Moreover, new training initiatives are underway with Persimmon Homes establishing a facility to train builders on modern construction technologies. The aim is to up-skill workers in the latest sustainable practices, enhancing the overall sustainability of housing projects and contributing to a reduction in carbon emissions in the building sector.

Australia is also advancing in sustainable building practices by investing A$2 billion to support the green aluminum industry. This signals a significant governmental commitment to cleaner production methods and aligns with global trends towards sustainability in heavy industries impacting construction supply chains.
