The consumption of products and services is based on a model of social and economic growth which requires the production of such products and services, the attraction of consumers, and profitability both for the producer and the consumer. The demand of products and services has the following effects: a) the intensification of production processes; b) the increase in resource extraction in order to satisfy the demand; and c) the appearance of non-sustainable models. The latter creates the need to balance demand of unsustainable products and services, and social development. In addition, the consumption of products is a social reference system that influences life styles and quality of life, as well as the acquisition of value systems linked to the consumption of these products and services. This paper will discuss some aspects regarding the impact of consumption on the environment. Impact can be measured through eco-efficiency indexes, for example, by analyzing the relationship between the economic contribution of a sector and its environmental pressure. The impact of tourism as a service can be assessed through analyzing the growth of the Raw Added Value and the quantity of water or energy necessary (with the consequent pressure on the environment) in order to maintain such a value, or the quantity of waste it generates (also with the consequent environmental pressure). Other services such as transportation, energy and construction, can also generate significant pressure on the environment that can be higher than the economic results obtained.
