The emerging Green Megatrend is expanding with relevant impacts in all the fields of the economy, confirming the requirement to consider sustainability as an essential complement of traditional business strategies. Existing strategic models and economic frameworks are required to take into account the growing implications for companies, for stakeholders and for the forces affecting competition. One particular model, the Balanced Scorecard, appears to be a good candidate to use in the management of sustainability strategy, thanks to its appropriateness, flexibility and the support coming from the evolution of information technology. The integration of sustainability in the BSC leads to three main models, from both theory and real cases. The appropriateness of these models has been evaluated along seven attributes and has been concluded bearing in mind the viewpoint of the particular target. The conclusions suggest that the best solutions consist of an integration of the sustainability strategy using traditional BSC model, and that the introduction of variants in the standard BSC may result in less effective models. This is additional evidence that the original BSC evolved with the capacity to support any dimension of a strategy, without the necessity to introduce new perspectives or structural changes in the original model. The same has happened in the past for the quality and information technology megatrends. Adopting any customized or hybridized BSC model will only represents improvements f rom the point of view of the communication but are sub-optimal solutions.
