Method and system with controller for controlling lighting devices

A system comprising:

• a plurality of lighting devices;
• and
• a controller configured to control operation of the respective ones of the plurality of lighting devices;
• wherein each lighting device is configured to store data indicative of one or more natural resources usage, the data including an inventory table listing resource usage of the respective lighting device accumulated so far during the lifetime thereof;
• wherein the controller is configured to:
• obtaining the stored data for each of the lighting devices;
• determine, for each of the lighting devices, a value of at least one environmental impact of the lighting device derived from the stored data of the respective lighting device by applying a transformation function to said data indicative of the one or more natural resources usage, wherein the transformation function depends on a Life Cycle Assessment (LCA) methodology;
• and
• control operation of at least one of the plurality of lighting devices based on the value of the at least one environmental impact determined for the respective ones of the lighting devices.
