The sustainable development issues have become one of the mainstream trends (possibly, the central topic) of the current international discourse in the field of social sciences and political journalism. Only COVID-19 pandemic could challenge its relevance. In this aspect, the situation in the Latin American or Iberian countries shows no difference from the world context. The consensus reached in 2015 as the Paris Agreement on Climate Change and the Sustainable Development Goals to be achieved by the year 2030 set by the United Nations General Assembly, became the pivotal moment in the public perception of the sustainable development subject. However, several inconsistencies remaining both in the interpretation of said goals and the definition of the sustainable development conception, prevent the world community from making concurrent decisions on joint steps and actions intended to overcome the defects of the unsustainable development. The author of this paper offers an improved (in his opinion) version of the sustainable development conception based on the comprehensive approach both to the determination and results of the economy, society and contemporary State development. © 2020.
