Resumen
The economic sciences have evolved and include new disciplines of analysis. While in 2014, Professor Jeffrey Sachs published his book The Age of Sustainable Development, the United Nations prepared an ambitious agreement for the sustainable development, which implies the imposing of measures on countryís actions in order to achieve this. In 2015, the Sustainable Development Goals were approved and the Vatican published the Papal encyclical, Laudato Si, which establishes life preserving guidelines and recommendations for ethical conduct. In parallel, Paris played host to the XXI COP21 United Nations Climate Change Conference, in which agreements were reached on reducing the emission of polluting gases, undoubtedly implying a rethinking of uncontestable issues such as economic growth which has dominated the agendas of the past decades.
