Neither the accumulation of wealth, the construction of housing or the unlimited consumption of products and resources will lift us out of a profound economic, energy and environmental crisis is which we live. The future belongs to those societies who facilitate the deployment of the entrepreneurial capacity for its citizens. Under this premise, Angel Pes and Norbert Bilbeny address the key role of the social responsibility of businesses, and from an eminently practical point of view, defend the need to promote entrepreneurial activity without neglecting the equitable distribution of the benefits of economic development as a sustainable model. They explain how to develop the requirements for a sustainable economy with numerous examples of businesses who have acknowledged the advantages that corporate responsibilities offer. To be a responsible entrepreneur is not only a choice, it is a necessity to build for the future.
