Individual and corporate responsibility is the basis for sustainable development of society and the world. Environmental responsibility of business entities is a prerequisite for the survival of people, which is why it is an important aspect of corporate responsibility. The purpose of the paper is to determine the content of corporate and social responsibility of business entities in the field of environmental protection in terms of its interaction with the state on the basis of public-private partnership. The general scientific method of comparison made it possible to compare the Ukrainian legislative base on environmental protection with the legal framework of regulation and practice in foreign countries. Through the structural and functional analysis, it was possible to consider the features of the interaction between the state and business structures and between other institutions the activities of which are related to environmental protection. The analysis revealed the necessity to consider and include elements of environmental and social responsibility of business in the mechanisms of public-private partnership. The study shows that public-private partnership is an imperative element in the composition of social responsibility. The author proposes a definition of environmental responsibility that encompasses three factors: legal, economic and social. In the future, this research area will be of interest as a comparison of the legislative support of the types of responsibility for foreign and international standards in the context of implementing the relevant standards in the Ukrainian legislative framework and their implementation on practice.
