Tampa in Florida is the city with the most trees, according to new research.
The Sensible City Lab at the Massachusetts Institute of Technology (MIT) has created a programme that has deduced that 36.1% of the city is covered by trees.
Singapore comes second at 29.3%, while Oslo is third with 28.8%. Central London has less than 13% tree cover.
However, as MIT has only surveyed 27 cities, the findings are not exactly conclusive. But it has made its code available here so you can help complete the picture.
