An awareness based approach to sustainability
The critical point in an evolving situation that leads to a new and irreversible development is called tipping point .
In our system the agents that are “ consistent and inflexible ” in their beliefs ” are the active ones and the evangelists , i . e . the green agents , but also the blinds .
In SAM4SN this notion is specialized and the sustainability tipping point ( STP ) is defined as “ a logical state variable that
becomes true when the relative number of green agents with a negative variation of individual consumption is greater than the 10 % of the total number of agents and the total number of green agents with a positive reinforcement is greater than the total number of unaware agents with a negative reinforce ”.
