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.
