GLOBAL WARMING – PHYSICS AND GEOPOLITICS (Review) 3. Reduction of anthropogenic greenhouse gas emissions

Introduction. Despite the global pandemic, reducing the negative effects of global warming and adapting to its devastating effects remains a pressing global problem. Its solution is actively taken care of by politicians, the world's leading scientific organizations and the expert community. Problems. Political, economic, innovative, scientific, technical and social approaches and measures to reduce and/or neutralize climate change and adapt to warming are widely discussed. World organizations - IPCC, IEA, WMO, etc. are involved in solving the problems. Goal. Assess the state of the problem, present the results of research and measures and tools for their implementation to reduce greenhouse gas emissions and/or adapt to their negative impact, in particular, in the energy sector - the largest producer of emissions. The main emphasis is on improving the energy efficiency of energy end-use, in particular, disseminating the experience of operational O&M (operation and maintenance) maintenance of passive buildings "zero-energy" in their energy supply from RES, as well as economic and financial leverage to reduce greenhouse gas emissions. Materials and methods. Authoritative recent literature sources with analysis of approaches, measures and tools to reduce greenhouse gas emissions are used. Weather-dependent (climatic) maintenance of the diagnostic-demonstration passive house of the "zero-energy" type with continuous system monitoring of parameters of engineering systems and building constructions and meteorological environment is organized. Results. Experience has been gained in the development and use of innovative energy-efficient technologies for energy supply of a demonstration passive house with O&M service by means of monitoring weather indicators and adaptation measures to climate change. Conclusions. The accumulated experience in the development of innovative energy efficient energy supply technologies and adaptation measures to climate change in O&M maintenance of zero-energy ITTF building of the NAS of Ukraine can be used in energy, in particular in municipal energy, and for the development of low-carbon energy. The use of approaches related to the taxation of excessive greenhouse gas emissions, or taking into account the decarbonization of the economy of production of goods and services in export-import operations, will also help reduce global warming.
