From the formality of documents generated by international agencies or the summits of Heads of Government to the drama that the environmentalists activists printed, there is agreement about the need to lower or abolish the current emission levels of carbon dioxide emissions. There is also agreement about which these emissions are generated by human activity. They are anthropogenic in nature as it is. Disagreements have begun, in terms of the causal patterns and intensities of attenuate or eliminate those emissions. These disagreements are increasing intensity as it could not be otherwise subject to the everlasting struggle for power, which in turn are necessarily biased ideologies or worldviews, of his opposing In this context, approaches to decrease emissions, are multiple. From our own limitations, together with the monographic and informative nature of this crucial problem, we will perceive that they are located on the one hand the wills who believe that this has a technological solution versus those who believe that this single is solved with a cultural change. There are those who believe that this should be resolved gradually and there are those who believe that there should be drastic and urgent efforts, and without straining the enunciation there are those who believe that this can be addressed with the mechanisms of the market, and there are those who believe that they are essential active public sustained policies. If in an attempt of understanding crossed the three choices (which reiterate not us) It seems that they are the only ones) and we characterized the three as a sort of range, or spectrum, we can perceive that there are at least theoretically mixed positions. But posts to take positions, we are inclined by the pole of cultural change, by the pole of the word, and have reservations about the ends of polarity market – active policies.Even our preference for the pole of cultural change, does not make us walk the path of the technophobia.We believe in incorporating criticism, selective and located the technological contributions.
