Fig. 4: Global mean surface air temperature responses to future food consumption GHG emissions for mitigation strategies and under a high-population projection.

Population projections were taken from the SSP3 Regional Rivalry population growth scenario. The scenarios include: (1) current dietary consumption patterns continued through to the end of the century ('no mitigation'); (2) a 50% decrease in retail-level food waste ('reduce retail food waste by 50%'); (3) a 50% decrease in consumer-level food waste ('reduce consumer food waste by 50%'); (4) full decarbonization of food production by the year 2050 ('decarbonization of food production'); (5) all people adopt a healthy diet as prescribed by the Harvard Medical School ('global conversion to healthy diet'); (6) technologically feasible production practice improvements are employed globally ('maximum production improvements'); and (7) all mitigation methods are employed simultaneously ('all mitigation methods'). The shading represents 95% confidence intervals based on 190 ensemble members and the lines represent the means of these ensemble members.
