Moss absorbs more carbon dioxide (CO2) per unit area than trees due to its dense, low-growing structure, which maximizes surface area for photosynthesis.

Unlike trees, moss doesn’t require soil, thriving on rocks, walls, or rooftops, making it ideal for urban environments where soil is scarce.

Its ability to retain water also helps regulate humidity and cool cities by reducing the urban heat island effect through evaporative cooling.

Moss can lower local temperatures by several degrees, improving air quality and reducing energy use for cooling buildings.

Removing moss, often seen as an aesthetic nuisance, disrupts these ecological benefits. It sequesters CO2 efficiently, with some species capturing up to 10 times more per square meter than trees.

Moss also supports biodiversity, providing habitats for microorganisms and small insects. In cities, it filters pollutants, improving air quality.

Preserving moss in urban planning—on green roofs, walls, or pavements—enhances sustainability without high maintenance.

Instead of removal, we should integrate moss into urban ecosystems to combat climate change, reduce heat, and promote biodiversity.

Encouraging its growth aligns with greener, cooler, and more resilient cities.
