Brick kilns are a major contributor to climate change and a significant source of CO2, GHG emissions and short-lived climate pollutants, particularly atmospheric black carbon. HZZK has shown how its energy-efficient, low carbon kilns could change lives and have a real impact in addressing climate change.

Air Pollution Casts a Pall Over Booming Bangladesh Megacity

Dhaka’s air quality is among the world’s worst, due to traffic, construction, and industrial pollution. For its 20 million residents, solutions are desperately needed.  Coal-fired brick kilns, dust from roads and construction sites, industrial pollution and smog blown in from neighbouring nations join diesel and gasoline fumes from local vehicles to create a toxic atmospheric stew,

AI could help detect unregulated sources of air pollution in South Asia

A collaboration between the University of Oxford and Lahore University of Management Sciences has combined the power of artificial intelligence with remote satellite imagery to help tackle the problem of unregulated brick kilns across South Asia. These kilns are a major source of air pollution, a key contributor to climate change, and notorious for people trafficking and modern-day slavery.

CSE welcomes MoEFCC’s new notification on brick kilns

It is a welcome step from MoEFCC to reign in uncomplying brick kilns through technology roadmaps or cleaner fuel options, says CSE… The Union Ministry of Environment, Forest and Climate Change (MoEF&CC) came up with stringent standards for brick kilns after seven years of deliberation via a notification dated February 22, 2022. Brick kilns have been identified […]
