Abstract: Climate change has been described by scientists, environmentalists and politicians as a threat unprecedented in human experience. Emissions of greenhouse gases from human activities constitute the proximate cause. Greenhouse gas emissions are related to the efficiency developments of spatial energy systems. The study analyses the efficiency development in the global world economy. This study is a comparative analysis of energy and CO 2 emission intensity effects in world regions from the years 1971-1999. The analysed regions are Latin America, USA, Africa, the Middle East, China, the rest of Asia and Europe. The comparative analyses are based on the complete decomposition methodology, from which the authors provide the analysis of dynamic changes of energy consumption and CO 2 emission flows compared with economic performance in the larger regional economies of the world. In this article, the authors report the activity effects, the structural effects and the intensity effects in these different world regions.
