Table 2 Overview of measures included in the sustainability scenario
From: Exploring pathways for world development within planetary boundaries
Category (policy) | Measure as implemented in the model |
|---|---|
Climate mitigation | Implementation of the 1.5 °C target of the Paris Agreement, implemented via price on GHG emissions, following SSP2-1.9 (ref. 41) |
Food-consumption change | Shift towards a healthy diet, as defined by EAT–Lancet (80% implementation in 2050 and 100% in 2100)45 |
Reduction of food waste | Reduction in food loss by consumption group (overall leading to halving food waste in 2050)46 |
Water withdrawal for energy, industry and households | Implementation of efficiency in water use in industry, the residential sector and electricity generation (leading to an overall reduction of around 20% in 2050)47 |
Water withdrawal for irrigation | Reduction in water use for irrigation to ensure environmentally and ecologically sustainable levels (leading to a reduction of around 30% in 2050)48 |
Use of N fertilizers | Increase in NUE to maximum levels by 70–80% in 2050 (compared to 50% as the baseline)49 |
