Description

The LA (Leaf Area) describes the total amount of leaf area of all NBS in a project area.

The LA (Leaf Area) is a Key Performance Indicator of the GREENPASS® system. It expresses the sum of leaf area of NBS within project area. The Leaf Area is the operating surface of NBS and therefore decisive for climate regulation, carbon storage and air purification.
