Indonesians Fight Climate Change With Tiny Islands
29 Jul
Summary
- Concrete production significantly contributes to climate change.
- Its use is expected to double, necessitating cleaner alternatives.
- Four Indonesians from a small, vanishing island are developing solutions.

Concrete accounts for a substantial portion of global construction materials, with its usage predicted to double in the coming years. This increase is partly driven by the need to address climate change, despite concrete production being a significant contributor to greenhouse gas emissions.
The industry is actively working on developing cleaner production methods and more sustainable concrete alternatives. However, innovative solutions might emerge from unconventional sources.
Four individuals from a small, disappearing island in Indonesia are at the forefront of developing new approaches. Their work offers a glimmer of hope for mitigating the environmental impact of concrete and addressing the challenges posed by climate change.
