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.

Resource use and environmental impacts are important factors relating to the sustainability of beef production in Australia. This study used life cycle assessment to investigate impacts from grass-finished beef production in eastern Australia to the farm gate, reporting impacts per kilogram of liveweight (LW) produced. Mean fossil fuel energy demand was found to vary from 5.6 to 8.4 MJ/kg LW, mean estimated fresh water consumption from 117.9 to 332.4 L/kg LW and crop land occupation from 0.3 to 6.4 m2/kg LW. Mean greenhouse gas emissions ranged from 10.6 to 12.4 kg CO2-e/kg LW (excluding land use and direct land-use change emissions) and were not significantly different (P > 0.05) for export or domestic market classes. Enteric methane was the largest contributor to greenhouse gas emissions, and multiple linear regression analysis revealed that weaning rate and average daily gain explained 80% of the variability in supply chain greenhouse gas emissions. Fresh water consumption was found to vary significantly among individual farms depending on climate, farm water supply efficiency and the use of irrigation. The impact of water use was measured using the stress-weighted water use indicator, and ranged from 8.4 to 104.2 L H2O-e/kg LW. The stress-weighted water use was influenced more by regional water stress than the volume of fresh water consumption. Land occupation was assessed with disaggregation of crop land, arable pasture land and non-arable land, which revealed that the majority of beef production utilised non-arable land that is unsuitable for most alternative food production systems.
