Figure SPM.2: Relative global development of Gross Domestic Product measured in PPP (GDP_ppp), Total Primary Energy Supply (TPES), CO₂ emissions (from fossil fuel burning, gas flaring and cement manufacturing) and Population (Pop). In addition, in dotted lines, the figure shows Income per capita (GDP_ppp/Pop), Energy Intensity (TPES/GDP_ppp), Carbon Intensity of energy supply (CO₂/TPES), and Emission Intensity of the economic production process (CO₂/GDP_ppp) for the period 1970-2004.
