Abstract

The paper considers the causes and consequences of climate change on planet Earth. Including global warming and the need to switch to alternative energy sources, as well as the decarbonization of various industries. It is shown that the main causes of global warming are human activities and the use of fossil fuels as energy carriers. The reduction of greenhouse gas emissions is closely related to the problems of changing the structure of the energy sector in almost all countries of the world. Listed are international organizations that deal with climate problems and monitor changes in temperature and the content of greenhouse gases in the atmosphere of the planet. The work of these organizations based on UN climate conferences in the period 1992 to 2022 to develop solutions aimed at the decarbonization of the main industries and, above all, energy is analyzed. It is shown that the Paris Agreement is a key element of the multilateral climate process. It is the first ever legally binding document that unites countries in the pursuit of a common goal of combating and adapting to climate change. At COP-26 in 2021, a climate package was signed, which confirmed the main goal of limiting global warming to only 1.5°C. Many promises have been made regarding the use of new technologies and renewable energy sources, improving the energy efficiency of old equipment. According to scientists' forecasts, climate changes will increase in all regions of the planet in the coming decade. Emissions of greenhouse gases as a result of human activity were and remain the main causes of global warming. However, after the start of the war in Ukraine, much of what most countries previously agreed to became unfeasible. The war changed the political and economic outlook, and global inflation escalated. The energy crisis has arrived. According to IPCC experts, 2022 has become a year of stagnation and a departure from previously chosen positions. It is shown that war can make some countries think about energy self-sufficiency and saving energy resources. These issues were discussed at the climate conference COP-27 in Egypt. Among the issues discussed at COP-27, the main one was the decarbonization of the energy system
