Table 3. Annual per person demand for red meat protein in 2020 and percent change in demand (2020 to 2050) under changes in red meat income elasticities by SSP.

SSP	Country group		Scenario for change in income elasticity trajectory
			Reference case (no change)	50% lower all countries	100% lower all countries	50% lower HIC only	100% lower HIC only
		Reference case average per person demand in 2020 (kg)	Percent change in per person demand 2020 to 2050
SSP1	All	4.6	22.3	5.1	−7.0	21.4	20.6
SSP2	All	4.6	10.1	−2.0	−11.2	9.4	8.7
SSP3	All	4.5	−2.7	−10.6	−17.1	−3.2	−3.6

Notes: Data in columns 4 to 8 are percent changes between 2020 and 2050 in each of the five scenarios listed in the second row. Demand is in protein and is summed over beef, sheep, and pork. Projected data simulated using income and population from three shared socioeconomic pathways (SSP). Average in 2020 reference case is demand from all countries in a country group divided by total population from all countries in a country group. All = all countries in the world, HIC = high-income countries, LMIC = low- and middle-income countries. SI Section 3 describes an additional scenario where red meat becomes an inferior commodity in high-income countries only, with Table SI.6 reporting the results of the additional scenario.
