Consumers' Behavior and Environmental Impact of Time Use: An analysis by the waste input-output model and a consumer model

For evaluating environmental impacts of consumption, a new model will be introduced. The model consists of two components; one is the waste input-output (WIO) model and the other is an economics model describing consumer's behavior. The model deals with the time-use aspect of consumer's behavior as well as the income aspect. The rebound effects with respect to both income and time can be considered in this model. Environmental impacts of some alternative consumption technologies are evaluated by this model. We found that some typical scenarios of sustainable consumption are literally more sustainable than the current consumption pattern.
