How much forest has Luxembourg lost?
Since 2001, the area within 10 km of Luxembourg has lost about 658 hectares of forest (about 920 football pitches): 5.4% of the forest it had in 2000. Most of it was lost to logging, so much of it can grow back. About 118 hectares (18%) was deforestation: forest cleared for good for farms, mines or towns.

Comparing satellite maps from 2000 and 2020, the forest around Luxembourg grew from about 13,600 hectares to 13,900 hectares, a net gain of about 313 hectares (+2.3%). New forest grew on about 523 hectares, while 210 hectares were lost.
These 2000 and 2020 maps, from the University of Maryland, count any land with trees taller than 5 m as forest, including plantations and orchards. Forest that was cut or burned and had grown back by 2020 counts in both years, so the loss here is smaller than the yearly figures.
These figures cover everything within 10 km of the city center, a wider area than the report above, because forest is usually lost at a city's edges.

How many more trees does Luxembourg need?
Luxembourg has already reached its tree-cover target, so no additional trees are needed to close the gap.
How are Luxembourg's air quality and tree cover measured?
Air quality is measured by ground monitoring stations near Ville Haute Luxembourg, via OpenAQ; the 7-day trend is the Open-Meteo / CAMS model's estimate. Tree cover is measured from Sentinel-2 L2A (ESA Copernicus) via Earth Search satellite imagery at 10 m detail across a 2 km radius around Ville Haute Luxembourg; the tree count is an estimate derived from that cover.
