Consumption-based and production-based accounting of CO₂ emissions by Peters et al. (2), divided into industrialized and industrializing countries (detailed in the text). (Top) CO₂ emissions to support consumption in developed countries exceeds CO₂ emissions to support consumption in developing countries, despite the fact that more CO₂ emissions are produced within the territory of developing countries. (Middle) On a per-capita basis, there is great disparity in consumption emissions between developed and developing countries. (Bottom) Consideration of a consumption-based perspective produces less of a difference in carbon intensity of economic activity (adjusted for purchasing power parity) between developed and developing countries.
