- A research team counted trees across Bunia city neighborhoods.
- They measured tree diameter, height and wood density carefully.
- The team did not cut any trees in plots.

- On average one tree stores a lot of carbon.
- Some species store much more carbon than others.
- Eucalyptus and mango are the top carbon trees.
- Cities can protect and plant trees to help climate.
