U tekstu autor ukazuje na nekoliko pitanja koja povezuju problematiku ustava s zaštitom okoliša. Je li je problematika okoliša i njegove zaštite sama po sebi razumljivi i \u27\u27prirodni\u27\u27 topos ustava? Zašto su i na koji način \u27\u27pozelenili\u27\u27 suvremeni ustavi i s kojim su se ustavnim i drugim pravnim problemima suočili njihovi tvorci? Koju je ulogu imalo prožimanja međunarodnog i nacionalnog ustavnog prava u tome greeningu i s kojim posljedicama? Zašto je potrebno harmonizirati vrednote ustava i okoliša? U tom kontekstu autora posebno zanima na koji je način ova problematika riješena u kontekstu suvremeng hrvatskog i europskog ustavnog prava.In this paper, the author points out a few questions which link the problem areas of the constitution with environmental protection. Is the problem area of the environment and its protection in itself an understandable and ‘natural’ topos of the constitution? Why and in what way have modern constitutions ‘become green’ and what constitutional and other legal problems have their creators faced? What role has the penetration of international and national constitutional law in this greening had and with what consequences? Why is it necessary to harmonise the values of the constitution and the environment? In this context, the author is especially interested in what way this problem area is resolved in the context of modern Croatian and European constitutional law
