Population peaks in 2070, GDP growth is moderate, and inequality declines steadily, GDP shares of sub-Saharan Africa and South Asia rise significantly. Rapid population growth, moderate economic growth and slow technological change in the energy sector. High inequality leads to reduced trade flows, leaving many parts of the world vulnerable, and with low adaptive capacity. Rapid development of low carbon energy technologies in key GHG emitting regions leads to relatively large mitigative capacity, but in other regions development is slow, inequality high, and adaptive capacity limited.
