A spread of lifebuilding elements, such as carbon, nitrogen, and oxygen in the Galactic discs is yet not well investigated. In this study, we use spectra from the UVES spectrograph (Gaia-ESO survey ) and the VUES spectograph (SPFOT-PLATO survey) and determine the carbon, nitrogen, and oxygen abundances in FGK stars using the same technique. For some of our target stars the Gaia space observatory has already presented accurate distances, thus we overview the first results of radial and vertical CNO abundance distributions in the Galactic thin and thick disc populations.
