High above Earth, a cutting-edge satellite is zooming around the planet 15 times a day. It is hunting for leaks of methane — an invisible, super-polluting gas that is dramatically warming the planet. Its measurements are precise enough to plot heatmaps of the biggest offenders, lighting up all the places they are venting the gas into the atmosphere at a staggering rate, unbeknownst to regulators. MethaneSAT’s early findings are that the oil and gas industry is belching the gas at a rate three to five times higher on average than what the Environmental Protection Agency has estimated, and way beyond the rate the industry itself agreed to in 2023. “This is just very, very revealing — for the first time, to see this kind of observation,” said Ritesh Gautam, lead senior scientist on MethaneSAT. “The images we started to see were just extraordinary in terms of the overall precision of the data.” Tap the link in bio for more. 📸 : Julian Quinones/CNN/MethaneSAT

Global investment in sustainable construction is accelerating, with a near $2 trillion pipeline of clean industrial projects reshaping the environmental sustainability in construction. Decarbonising the built environment now centres on reducing embodied carbon and whole life carbon across cement and steel production. Institutional capital is driving innovation toward low carbon construction materials and renewable building materials, allowing low carbon design principles to progress from concept to large-scale implementation. Green construction methods are expanding through eco-friendly construction strategies that prioritise life cycle thinking in construction, resource efficiency in construction, and circular construction strategies designed to reduce the carbon footprint of construction.

Cities are positioning sustainable urban development as a core element of climate resilience planning. Global municipalities are seeking more than $105 billion in funding for green infrastructure and nature-based solutions that deliver measurable improvements in building lifecycle performance. These initiatives increasingly require whole life carbon assessment and lifecycle assessment frameworks to align with net zero carbon buildings targets. The uptake of environmental product declarations (EPDs), BREEAM and the forthcoming BREEAM V7 standards reflects a clear commitment to evidence-based sustainable building practices and eco-design for buildings that meet low-impact construction and circular economy in construction goals.

The skills shortage threatens this progress. The UK faces a deficit of at least 14,000 trade apprentices within the green construction sector, limiting capacity for sustainable building design and life cycle cost optimisation. This talent gap risks slowing the transition to net zero whole life carbon operations and undermines cost control on major projects. Expansion of training in sustainable material specification, carbon footprint reduction, and end-of-life reuse in construction is essential to secure both project delivery and compliance with evolving embodied carbon in materials benchmarks.

Global climate policy fragmentation is adding pressure. Divergent national commitments create uncertainty for carbon neutral construction investors while the EU’s focus on low embodied carbon materials and comprehensive lifecycle frameworks strengthens its position as a leader in sustainable architecture and circular economy policy. The convergence of technology, governance, and skill development defines the next decade for sustainable design. Those integrating whole life carbon principles and rigorous life cycle thinking into procurement and project management will define the future of energy-efficient buildings and ensure the long-term competitiveness of the green building products sector.
