The article considers the role of public-private partnership in the development of the «green» economy. The author reveals the concept of «green» economy, justifies the importance of introducing «green» technologies that allow to move from a wasteful economic model to an environmentally friendly one. The main idea of the concept of «green» growth, which implies sustainable development without irreversible destruction of natural resources, is reflected. The author highlights the main directions of development of the «green» economy, which are widespread in most countries, including Russia. The expediency of using the mechanism of public-private partnership in the transition to the «green» economy model is justified. The problems of implementing environmental projects are highlighted, primarily due to insufficient financial resources, both from the state and private business. It was revealed that cooperation between the state and the private sector forms an effective mechanism for attracting investment aimed at ensuring «green» economic growth. It is noted that when implementing PPP projects aimed at «green» economic growth, three main sectors receive the greatest development: energy based on renewable sources; water supply and sanitation (Sewerage); solid waste management. These areas receive preferential financial support for projects around the world from the world Bank structures, as well as state support in Russia. The author analyzes PPP projects in these sectors funded by the world Bank and identifies priority areas. The features of similar PPP projects implemented in these three regions in Russia are considered. It is revealed that such projects have not yet become widespread, and those that are being implemented are aimed more at the reconstruction of previously created objects than at creating modern and more environmentally friendly ones.
