Description

Global warming by greenhouse gases has become the most urgent and critical environmental concern for the mankind. About half of current increases in commitment to global warming is due to carbon dioxide (CO2) and majority of this is caused by the consumption of energy from carbon-based fossil fuels. As a consequence of international studies, it has become widely recognized that the nations as a whole should take measures to drastically reduce their use of fossil fuels and change their energy dependent growth patterns to sustainable development paths which will be more reliant upon renewable energy sources rather than fossil fuels. In order to seek for an optimal development path under such environmental and energy constraints, this paper presents a world dynamics model to describe the future world development by taking into account the interaction among population, energy, production (GNP), food production, land use, etc. Consumption paths of energy and other limited resources are studied by applying logistic type learning curves. Based on this model, policy options for responding to global warming is discussed and their environmental and economic implications are examined.
