Abstract: The paper outlines the leading theories and concepts in categorizing the concept of green economy. The idea of an environmental friendliness, competitive, green economy is interpreted as contributing to sustainable development and effectively use of resources. Green economy helps solving problems of the slowdown in economic growth and job losses, as well as the continued deterioration of environmental quality and ecosystem degradation. All this defines the green economy as an approach to achieving sustainable development. Economic growth measured by the size of the gross national / social product cannot continue to be used without the appearance of environmental problems. he green economy has become one of the pillars of major international and European strategies and is being considered as an approach leading to a structural transformation of the economy.The results of the Green Economy research distinguishnine strategic areas: sustainable consumption and production through responsible consumers and producers; knowledge society through information development and training; government to help adapting to new business realities; climate change and energy; sustainable transport and mobility; conservation and sustainable management of biodiversity and natural resources; public health and risk prevention with an emphasis on environmental quality; demography and migration and social inclusion; challenges in the field of sustainable development; global poverty reduction.The theme of green economy is more and more relevant for Bulgaria, it is constantly being discussed and there is an increasing awareness of the importance of this transition to a green economy, which is associated with the high price that a society has to pay. But this is the only way our generationto take care of the coming generations and thus conserve the planet's resources.
