Sustainability status

Physical and Socio-Economic Sustainability Status of the World

Building on the work of Rockstrom et al, 2009 [1], Dearing et al. [2] and Raworth [3], researchers at UOIT are proposing a new framework for sustainability that integrate physical and socio-economic indicators to demonstrate the physical limits of sustainability for the world’s largest cities.

The physical science indicators adapted from the boundaries proposed by Rockstrom et al [1] are demonstrated in Figure 1 and Table 1.

The socio-economic indicators are demonstrated in Figure 2 and Table 2, which provides approximate global social boundaries (i.e. socio-economic) estimated in relation to existing targets and global limits.
