When tour guide and wildlife photographer Gaurav Ramnarayanan set out on safari on the evening of January 24, 2024, he wasn’t looking for tigers. The 25-year-old was leading a private tour in the UNESCO World Heritage Site of Kaziranga National Park, a 430 square-kilometer wildlife reserve in India’s northeastern Assam state. While it’s home to the largest tiger population in the region, sightings are rare and the park is better known for its other wildlife. He began driving, turning a corner before stopping the car in its tracks: there was a tiger on the road. “Initially when I saw him, he looked really white and didn’t look like a normal (Bengal) tiger,” says Ramnarayanan. “I’ve seen enough tigers to realize at the first glance that this one was not regular.” His suspicions proved right when he looked at the predator through his camera lens: with strawberry-blonde stripes, the big cat was unmistakably a rare “golden” tiger. Golden tigers — also known as golden tabby tigers or strawberry tigers — are not a subspecies: they’re the result of a genetic mutation that changes the color of their fur. And while beautiful, their presence has a dark side. Read more at the link in our bio. 📸: Gaurav Ramnarayanan

The UK construction sector is entering a decisive phase of sustainable construction focused on measurable carbon reduction rather than symbolic gestures. The launch of the UK’s first commercial‑scale carbon capture and storage facilities in the East Coast Cluster, operated by pX Group, marks significant progress in decarbonising the built environment. These links between energy‑intensive industries and new CO₂ transport and storage systems are reshaping the embodied carbon profile of essential materials such as cement and steel, critical to sustainable building design and eco‑friendly construction. The integration of low embodied carbon materials forms a foundation for the adoption of whole life carbon assessment methods and lifecycle assessment strategies now demanded across the supply chain.

Concrete innovation is accelerating as “green concrete” becomes a viable element of low carbon design. Manufacturers are scaling from trials to full delivery. JCB’s move to provide a 100% biodiesel option for tracked excavators demonstrates practical progress toward net zero carbon buildings and carbon neutral construction. Effective reductions depend on verified renewable building materials and traceable biofuels, requiring stricter sustainable material specification and transparent environmental product declarations (EPDs). Verified sourcing and supply are vital to minimising the carbon footprint of construction and improving resource efficiency in construction.

Across projects, whole life carbon thinking is now inseparable from life cycle cost analysis. Intensifying climate conditions—from escalating floods to drought stress—demand resilient, energy‑efficient buildings and green infrastructure designed using eco‑design for buildings principles. Resilience and sustainability are no longer optional performance indicators but integral to building lifecycle performance and sustainable building practices. The industry response is to secure supply from emerging low carbon construction materials clusters, adopt verified fuels and plant emissions data, and embed circular construction strategies.

The momentum reflects a commitment to environmental sustainability in construction, combining circular economy in construction models with frameworks such as BREEAM V7 to achieve net zero whole life carbon outcomes. Through transparent lifecycle assessment and life cycle thinking in construction, every project can demonstrate measurable progress in carbon footprint reduction and deliver the economic and environmental returns driving the transition to sustainable urban development.
