Abstract. Climate change has become a threat to sustainable development for all developing countries, and measures to mitigate and adapt to this phenomenon must become a priority in national policies. Therefore, the Republic of Moldova is directly affected by Climate Change, being more vulnerable to adverse effects. As a result, Climate Change presents a serious danger for the achievement of the Millennium Development Goals, which the Republic of Moldova has assumed. At the same time, Climate Change can generate opportunities for the transformation of the economy, providing greater sustainability and thus paving the way to reducing poverty and achieving the Millennium Development Goals. Excessive consumption of natural resources of the growth generation emissions of greenhouse gases, causing in the last century the warming of the Earth and the disruption, finally, of the global climate system. These problems put the scientific community in front of the dilemma of finding the compromise between economic development and its effects on climate change. Finding this compromise will mean the sustainable development of mankind. Studies show that the impact of global warming is directly proportional to the standard of living of the population, and it affects the inhabitants of poor countries the most, which, in fact, have polluted the least. The problem of Climate Change can only be solved with synergistic efforts of all the states of the world, that is why the Framework Convention of the United Nations Organization on Climate Change (CONUSC) was created. This study was developed within the State Program 20.80009.0807.22 "Development of the mechanism for formation of the circular economy in the Republic of Moldova” funded from the state budget through the National Agency for Research and Development of the Republic of Moldova.
