Climate Action Project: Brick-to-Block Transition Hub
Brick-to-Block Transition Hub (B2B-TH) is a youth-led initiative in Sreepur, Gazipur, Bangladesh, working to replace polluting brick kilns with cleaner, safer building practices. Traditional kilns burn coal and destroy fertile topsoil, harming both the environment and the health of workers.
B2B-TH introduces Compressed Stabilized Earth Blocks — a low-emission, unfired alternative — and trains kiln workers in this sustainable technology. The project centers both environmental restoration and worker wellbeing, offering hands-on training and a pathway to safer livelihoods.
The team will produce sample blocks, gather impact data, and build momentum toward a permanent hub for green construction. By combining climate action with care for frontline communities, B2B-TH is laying the foundation for a more just and sustainable future.
