Solomon Islands as a whole
89.8% of the Solomon Islands was forested as of 2024, against a 30% benchmark. That already clears the benchmark — the city reports above show where cover is still thin locally. Source: World Bank (FAO).

How does Airleaf measure air quality in the Solomon Islands?
Each city's reading is the US EPA air quality index, from ground monitoring stations where one has reported recently nearby, and from the CAMS atmospheric model elsewhere; each city's report says which. Tree cover is measured over the same 2 km radius in every city, so the cities compare like for like.
