Trees absorb more CO₂ than previously thought

A new study from the University of Southern California reveals that urban trees absorb significantly more CO₂ than previously thought. In Los Angeles, researchers monitored atmospheric CO₂ levels over an 18-month period using a dense network of sensors. The findings: during daylight hours, trees absorbed an average of 60 percent of CO₂ emissions — a surprisingly high number, especially in a part of the city not known for its greenery.

Measurements were taken along the city’s prevailing wind direction, with CO₂ levels clearly declining as the air moved through — a strong indicator of the trees’ carbon absorption capabilities. Lead researcher Will Berelson notes that these insights could help other cities more effectively track emissions and strategically plan urban greening initiatives.

Despite the promising results, Berelson cautions: relying solely on urban trees is not enough — emissions must still be significantly reduced.
