Indicator
Circular Business activities are revenue-generating activities, that contribute to the circular economy through one or more R-strategies. Core circular business activities generate at least 70% of the total business revenue. The port area is defined as the geographical territory managed by the Port Management Body.
This indicator is relative, expressed as a share comparing the area occupied by core circular business activities to the total port area.
How to measure its value
Circular business activities can be identified by the relevant NACE-codes (Bel-first), linked to the R-strategies. The port managing body can be asked to check for missing or wrong data.
Suveys can be conducted with the businesses that conduct core circular activities.
Notes
The hierarchy of R-strategies and their contribution to the circular economy are currently not considered. Occupied area can be measured by full plot size or estimated proportionally to circular activities, though this approach may involve inaccuracies.
