How much carbon dioxide do parks and individual trees in cities absorb, and how much do they release? To answer this question, researchers at the Technical University of Munich (TUM) have developed a high-resolution CO₂ biogenic flux model. Their findings show that, on average, around 2% of Munich's annual urban emissions are compensated by vegetation. Urban trees have the greatest impact, whereas grassy areas are often net sources of CO₂.
