The beginning of Green Marketing or Ecological Marketing started in the 1960’s, due to climate changes and a new concern for the environment. Authors such as Ottman, Hailes, and Polonsky have contributed a great deal from the theory to the market conceptualization of Green Marketing. In Colombia, there is specific research on the implementation of Ecological Marketing in large corporations that also shows the analysis of the green consumer for a given product. This article’s principle objective is to present Ecological Marketing conceptualization from case studies that allow the reader to make interpretations from facts, experiences, and perceptions related to Green Marketing in Colombia.
