“I was my own boss. I could sell churpi [yak cheese] if I needed any money. Now I have to ask my husband for literally everything. It’s like yak calves asking their mothers for milk,” Tashi Lhamo tells CNN with a sigh.
The Tashis belong to a semi-nomadic ethnic group known as the Brokpa and like so many other Bokpa, were once yak pastoralists. The couple owned over 200 yaks in their ancestral village, Lubrang. In those years, they would spend the summer months on the move, leading their yaks between mountain pastures. In the winter they would return to their village, their yaks grazing in nearby fields.
The Brokpa traditionally earn their livelihood by selling yak products: milk, cheese, fur and meat. They also farm in their villages. But over the past few decades, climate change has significantly affected Brokpa pastoralists, forcing many to give up yak rearing.

Digitalisation and decarbonisation are integrating at pace across sustainable construction. At Scotland’s Monklands project, digital workflows enable whole life carbon assessment and precision tracking of embodied carbon, cutting life cycle cost through predictive design and optimised offsite fabrication. The Durham initiative applying automated site assessment tools has accelerated approvals while reducing the carbon footprint of construction, aligning data efficiency with environmental sustainability in construction.
In Liverpool, biophilic eco-design for buildings demonstrates how sustainable building design is contributing to low carbon design and improved occupant wellbeing through living architecture that enhances green infrastructure. Government policy now links affordability with sustainability. Early measures from the Burnham administration suggest a commitment to decarbonising the built environment and net zero carbon buildings through incentives rooted in life cycle thinking in construction.
Regulatory pressure is mounting as agencies introduce more robust frameworks for carbon footprint reduction, reinforcing accountability across the industry. Material innovation remains central to progress. Enzyme‑based recycling and a £125 million facility for chemical reuse in Darlington indicate that circular economy in construction and circular construction strategies are moving into mainstream infrastructure.
These advances in low embodied carbon materials, renewable building materials, and green building products signal a shift towards carbon neutral construction supported by verifiable environmental product declarations (EPDs). Across digital tools, biomimetic systems, and progressive material science, sustainable building practices are redefining building lifecycle performance, embedding whole life carbon accountability into every stage. Efficiency, resilience, and ecology are converging to deliver net zero whole life carbon outcomes consistent with BREEAM v7 principles, confirming that sustainable design is now integral to construction’s economic and environmental logic.
Whole Life Carbon is a platform for the entire construction industry—both in the UK and internationally. We track the latest publications, debates, and events related to whole life guidance and sustainability. If you have any enquiries or opinions to share, please do
