In the context of increasing population and of its needs, of the industrial development, transport and other human activities, including those regarding domestic consumption, alongside natural phenomena and processes, all these are generators of greenhouse gas (GHG) emissions. The increase of their concentration in the atmosphere alters its physical-chemical balance, contributing, on longterm, to the climate change, as the world is really concerned nowadays about the global warming. That is why we present here the analysis of the longterm evolution of GHG worldwide, from carbon oxides, to methane, to nitrogen oxides and anthropogenic fluorinated and hydrogenated carbonated compounds. The data are taken from the EDGAR database (Emission Database for Global Atmospheric Research) given by the Joint Research Centre, which is the European Commission's in-house science service, within the efforts of the European Union to keep a close eye on the evolution of the environment and to be able to know when and how to adapt the European and national policies in order to maintain our lives in as good conditions as possible, such that the sustainable development would be accomplished.
