The “three horses of sustainability” – the IPAT equation provides a simple but powerful model for understanding the roles of population, affluence and technology, particularly from the challenge posed by the Anthropocene – how to reduce one’s personal or societal impact.
It takes an actor’s perspective, liberating the question of reducing impact from a technical to a behavioural one; i.e. “how much do I need to change to achieve sustainability?” The model helps by offering multiple pathways, through stabilizing or reducing population, affluence and/or technology or material use, helping to build trust and confidence among actors to support collective action.
