The issue of the future legal regulation of environmental protection during the negotiations on the with- drawal of the United Kingdom from the European Union was one of the most controversial. As is well known, the regulation of environmental protection and climate change, as well as the policy of the EU Member States in this area, belong to the so-called joint competence of the EU and the Member States. The EU, through well-developed environmental legislation, is currently regulating such areas of public relations as nature, bio- diversity, waste and waste recycling, and so on. Environmental quality, clean air and water, healthy flora and fauna in modern conditions can only be ensured through cross-border cooperation, and EU legal standards promote the development of new technologies and businesses. Investors in companies involved in renewable energy and clean technologies, as well as waste and recycling, have faced some difficulties in reviewing EU national legislation during the transition period. The formation of new standards, despite the preservation of certain union rules, is gradual. As a result, Britain’s withdrawal from the EU has inevitably affected to some extent all aspects of its environmental policy, as well as the quality of life of Britons. Undoubtedly, the United Kingdom will continue to pursue trade relations with the European Union but may want to lower radical national environmental standards, which in turn will give the country a competitive advantage over the EU. This article examines the legal and political considerations behind Brexit in light of the United Kingdom’s international commitments to the environment, including climate change. The authors argue that deregulation pressure calls into question the realization of the British dream of a «greener» state after Brexit.

The article is devoted to the analysis of public law mediation in the settlement of international conflicts. Using the example of the armed confrontation on the territory of the Republic of Cyprus that took place in 1974, the authors analyze the role of international intermediaries (mediators) in resolving the armed conflict and overcoming its consequences. The causes of the Cyprus armed conflict are studied, and the conditions under which public law mediation is expedient are analyzed. At the same time, the conditions for providing mediation services in the settlement of such conflicts are evaluated. In the conditions of the armed aggression of the Russian Federation against Ukraine, the study of the role of mediation in international law plays a positive role, taking into account the aspiration of some UN member states to play a positive peaceful conciliatory role in the cessation of military aggression by the aggressor state.             Along with the abovementioned, the positive features of public-law mediation are noted and the consequences of using this institute of mediation procedure in armed conflicts are described. The criteria for evaluating the effectiveness of public legal mediation are expressed. It also describes the conditions under which the guarantor states assumed international obligations regarding the settlement of the Cyprus crisis.             The conclusions indicate attempts to settle it, which, unfortunately, did not find the support of the population of this island state. Along with this, it is noted that the subjects of public-legal mediation act as mediators not only in the solution, but also in the possible introduction of peaceful measures that will mitigate the international conflict. As an example, Turkey's participation in unblocking the work of Ukrainian seaports for the purpose of exporting food products by sea transport during the armed aggression of the Russian Federation against Ukraine in 2022 is given.

The article examines the issue of formation and development of cooperation between the member states of the European Union in the field of cultural property protection. It has been established that over the past several decades there has been a tendency to strengthen the role of culture, including for regional organizations, which is clearly visible in the activities of such an integration association as the European Union, where culture is used as a kind of catalyst for the development and strengthening of dialogue between states. At the same time, the European cultural heritage is a very important part of the common cultural space both for the EU institutions and for the citizens of the member states; and the fact that half of the monuments of the world’s historical heritage are concentrated on the territory of Europe, illustrates the depth and volume of the cultural layer that needs to be preserved, which requires the EU to carry out concerted actions in the field of protection of cultural values. The author draws attention to the fact that the first contractual documents did not provide for a system of norms regarding the cultural sphere, but despite the lack of relevant competences, the EU was forced to deal with cultural issues already at the first stage of its integration. The 1974 recommendation on the protection of the architectural and natural heritage (75/65/EEC) was almost the first document that declared an interest in the protection of cultural values. Later, in the eighties and nineties of the XX century. it is possible to notice the introduction of norms that partially regulate the movement of goods in the field of culture, the growth of society’s activity in the cultural sector, and since the 2000s, systematic measures aimed at the development and support of European culture, which is already considered as the main tool for implementing the EU’s external interaction, have been observed . The last decade is associated with the intensive development of the idea of intercultural dialogue as one of the main paradigms of a single European policy aimed at consolidating the common cultural space in Europe. It was concluded that the formation and development of the unified cultural policy of the EU, including the cooperation of the member states in the field of protection of cultural values, did not have a linear character, and this process is still ongoing. In particular, significant efforts are being made to combat the smuggling of cultural values and the return of cultural values.

The article improves the mechanism of management of investment activities of economic entities on the basis of coordination of the interests of all participants in the investment process through the use of adequate management instruments. It is found out that the management of investment activity is a complex, multilevel process that involves managerial decisions not only at the level of economic entities – investors and participants in investment activities, but also at the State and region levels. It is noted that the enterprise management system should be flexible and respond in time to changes in the modern economic system. An important aspect in the implementation of investment activity should be the process of both attracting and using investment resources, which in the future will ensure an increase in the value of the enterprise. An improved mechanism of management of investment activity of enterprise is proposed, which includes: consistency and method of management; a sequence of processes and stages, appropriate procedures and instruments; a set of institutional and organizational structures and a complex of forms and methods used by them; a sequence of application of various methods. The practical implementation of such a mechanism is possible by aligning the interests of all participants in the investment process through the use of adequate management instruments. It is concluded that the improvement of the efficiency of management of investment activity of enterprise can be achieved only after taking into account all the factors affecting its level both macro and meso (that is, on the part of the State, region and industry sector), and also at the micro level (on the part of the enterprise itself). Only the combination of efforts both by the State and by individual enterprises at different levels will allow the Ukrainian economy to overcome a number of existing problems and attract the necessary amount of funds for economic development and profitable activities of economic entities. Activation of investment processes in Ukraine is possible under the conditions of development of appropriate mechanisms of management of investment attractiveness of economic entities.
