The UK government has rolled out a new £100 million subsidy program supporting green roofs and vertical gardens on public buildings in London. The aim is to tackle urban heat islands, improve air quality, and reduce cooling costs in dense city areas. Pilot installations on libraries and hospitals have already reduced roof temperatures by 10–15%. Urban planners in Kolkata, Dhaka, and Kathmandu are exploring adoption of similar schemes to combat rising summer heat in South Asian cities.
The move aligns with sustainable urban design and climate resilience goals across rapidly growing metropolitan regions.
