Fig. 1: Feasible solutions (areas below the equivalence curves) if the weak sustainability (WS) and a-growth (AG) paradigms are applied for combinations of future technologies (θ) and preferences (η), where θ = 1 depicts current technology and η = 1 depicts the current preference for consumption.
From: Environmental sustainability is not worth pursuing unless it is achieved for ethical reasons
WS (yellow) is never feasible, so it is not shown. For AG (blue), the only feasible equivalence curve refers to σ = 1 (the most certain scenario); there are no feasible equivalence curves for σ = 2, 3, and 4.
