The huge energy requirement for industrial separations of chemical mixtures has necessitated the need for the development of energy efficient and alternative separation techniques in order to mitigate the negative environmental impacts associated with greenhouse gas emissions from fossil fuel combustions for energy generation.

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.

Following the global trend towards increased energy demand together with requirements for low greenhouse gas emissions, Adaptable Reactors for Resource- and Energy-Efficient Methane Valorisation (ADREM) focused on the development of modular reactors that can upgrade methane‐rich sources to chemicals. Herein we summarise the main findings of the project, excluding in‐depth technical analysis. The ADREM reactors include microwave technology for conversion of methane to benzene, toluene and xylenes (BTX) and ethylene; plasma for methane to ethylene; plasma dry methane reforming to syngas; and the gas solid vortex reactor (GSVR) for methane to ethylene. Two of the reactors (microwave to BTX and plasma to ethylene) have been tested at technology readiness level 5 (TRL 5). Compared to flaring, all the concepts have a clear environmental benefit, reducing significantly the direct carbon dioxide emissions. Their energy efficiency is still relatively low compared to conventional processes, and the costly and energy-demanding downstream processing should be replaced by scalable energy efficient alternatives. However, considering the changing market conditions with electrification becoming more relevant and the growing need to decrease greenhouse gas emissions, the ADREM technologies, utilising mostly electricity to achieve methane conversion, are promising candidates in the field of gas monetisation.

Buildings are responsible for a large portion of global greenhouse gas emissions. While energy efficiency features can significantly reduce the greenhouse gas emissions during a building’s operational stage, extra materials and processes associated with these features typically involve higher greenhouse gas emissions during the construction phase. In order to study this relationship, a case study of a highly energy-efficient house in rural Alaska was performed. For the purposes of this case study, a theoretical counterpart home was designed that has the same interior space, but insulation values close to the code minimum requirements. Using computer simulations, a Life Cycle Assessment (LCA) was performed for the case study home as well as its conventional counterpart. The extra greenhouse gas emissions associated with the construction of the case study home were compared to the annual savings in greenhouse gas emissions achieved thanks to the energy efficiency features, and carbon payback was calculated. The carbon payback was calculated to be just over three years, which is only a small fraction of the life of the building. The results of this study show that despite higher greenhouse gas emissions during the construction phase, highly energy-efficient homes can play an important role in addressing climate change.

Global warming, caused mainly by greenhouse gas emissions, prompted the world community to sign the Kyoto Protocol in 1997. The regulation of greenhouse gas emissions and related economic activities have ceased to be the prerogative of national authorities and become the subject of international agreements. Due to the largest air pollutants from the world's oceans are ships, the International Maritime Organization (IMO) adopted in 2003 Resolution А.962 (23): "IMO Policy and Practice on Reducing Greenhouse Gas Emissions from Ships", and determined that it is possible to achieve significant reductions in greenhouse gas emissions from ships through the adoption of technical and operational measures. This suggests that ships need to be more energy efficient, operating conditions are well thought out, and a clear methodology for assessing ships in terms of greenhouse gas emissions. The estimated energy efficiency factor of the vessel is the Energy Efficiency Design Index (EEDI), which is calculated according to a formula developed by IMO with the possibility of improving it through innovative energy efficient technologies. Since the entry into force of the IMO resolution, mainly work is underway to improve the EEDI based on existing innovative technologies in various categories. Progress does not stand still, but the list of new innovative technologies for energy efficiency categories has not expanded. The presented article is devoted to the development of innovative technology of category C, to improve the energy efficiency index of the ship structure. This technology can used on its own, as well as an additional tool to extend the capabilities of existing energy efficiency technologies. In addition, the innovative technology for reactive energy compensation allows improving the EEDI and environmental performance of already operating vessels, through their simple modernization during planned repairs. Keywords. Energy Efficiency Design Index (EEDI), innovative energy saving technologies, power factor correction
