The issue of reducing greenhouse gases is of concern to the international community, as the possibility of an environmental catastrophe in the next ten years is becoming more and more real. Therefore, the search for effective tools to regulate, control and monitor private sector activities is a pressing issue. The use of restrictions is ineffective and contributes to slowing down economic development. From this perspective, the importance of the study lies in the qualitative means of building a public-private partnership to address greenhouse gas issues. The importance of the article is due to the need to find mutually beneficial compromises between the state and the private sector to achieve global strategic goals. The article aims to study the environmental and economic feasibility of building an effective model of private-public relations in the area of greenhouse gas emissions reduction. Control over the private sector should be enshrined at the national level, and specialized decentralized public authorities should be established to monitor the activities of the corporate sector. The article focuses on the current environmental situation in European countries and Ukraine and outlines the most efficient model of interaction between private and public relations to overcome negative environmental consequences. The main tasks are to find optimal solutions for the functioning of the private sector and possible government intervention while minimizing negative economic consequences. The research methodology involves disclosing the theoretical and methodological foundations of publicprivate partnerships, conducting statistical analysis of environmental threats, and determining the most appropriate model of public-private partnerships. The results of the study can improve the interaction of public administration with the private sector, as well as create the most effective model of their interaction under internal socio-economic and geopolitical circumstances.
