A smog-choked province in eastern Pakistan has issued a rare plea for cross-border collaboration with India, as major cities in both countries endure severe air pollution that risks the health of millions.
Officials in Punjab, Pakistan's most populous province of 127 million people, have drafted a letter to the Indian government to open a dialogue on the issue, Punjabi Secretary for Environment and Climate Change Raja Jahangir Anwar said.
"We need climate diplomacy, as a regional and global issue," Anwar told CNN, just days after Punjab's megacity of Lahore, roughly 15 miles from the Indian border, saw its highest-ever levels of air pollution.
"We are suffering in Lahore in a way due to the eastern wind corridor coming from India," he said. "We are not blaming anyone, it's a natural phenomenon."
India and Pakistan have for decades navigated fraught and at times hostile relations, but as the issue of toxic air worsens, the neighbors are being forced to confront their shared responsibility – and fate – when it comes to the climate.

Wildfires destroying homes in the Midlands and Shropshire crews moving between fire and flood show why sustainable construction must now treat climate resilience as a core design requirement. Sustainable building design, low carbon design and eco-design for buildings need to account for overheating, fire risk, drainage capacity, defensible space and durable fabric performance.
Whole life carbon, embodied carbon and life cycle cost are becoming inseparable from safety, insurability and asset value, making whole life carbon assessment and lifecycle assessment essential tools for developers, councils and investors.
Karachi’s mangrove loss reinforces the construction value of green infrastructure and nature-based flood protection. Tidal creeks, mangrove belts and resilient coastal landscapes can reduce erosion, store carbon and protect communities, supporting environmental sustainability in construction without relying solely on hard engineering. For sustainable urban development, green construction and eco-friendly construction must prioritise site planning, biodiversity and building lifecycle performance alongside energy-efficient buildings and net zero carbon buildings.
Plans for a wind-turbine recycling facility in the Scottish Highlands point to a more mature circular economy in construction. Renewable infrastructure must address end-of-life reuse in construction, resource efficiency in construction and the embodied carbon in materials, especially composite blades and complex low carbon construction materials. The shift supports circular construction strategies, low embodied carbon materials and net zero whole life carbon targets, aligning with BREEAM, BREEAM v7 and wider expectations for environmental product declarations (EPDs). The strongest signal for decarbonising the built environment is clear: sustainable building practices must measure the carbon footprint of construction across design, use, maintenance and decommissioning.
