Due to COVID-2019 related orders International Conference on Sustainability and Climate Change cities was successfully held online on May 22, 2020. The conference is devoted to new technologies that enable sustainable development and climate change.

There were 3 major sections of the scientific track of the conference:

- Sustainable energy

- Technologies for sustainable development

- Ecosystem development

- Regional aspects of sustainable development

This volume of IOP Conference Series: Earth and Environmental Science (EES) is a compilation of the accepted papers in ICSCC 2020 and represents contributions that were presented in the conference.

On behalf of the organization committee I would like to thank all of the conference sponsors, partners and volunteers who made conference possible.

Looking forward to meeting you during ICSCC 2021.

On behalf of organizing and program committees of the ICSCC 2020

Igor Balk, ICSCC 2020 co-chair.

All papers published in this volume of IOP Conference Series: Earth and Environmental Science have been peer reviewed through processes administered by the proceedings Editors. Reviews were conducted by expert referees to the professional and scientific standards expected of a proceedings journal published by IOP Publishing.

Today, Russia has the second highest value of GDP energy intensity in the world. Among many factors that determine this indicator, special mention can be made of low use efficiency of the fuel and energy resources. This leads to a decreased competitiveness of the national economy. The aim of this paper is to identify practical challenges that serve as a barrier to the reduction of specific energy consumption and to respond with optimal solutions at the level of a territorial entity of Russia (the Sverdlovsk region). The analysis of the fuel and energy balances and the gross regional product between 2015 and 2018 enabled us to identify the changes in the pattern of fuel and energy resources consumption in individual sectors of economy, as well as influencing factors. Special attention is given to the dynamics of average specific energy consumption indicators and to the status of communal infrastructure in the housing and community amenities sector. The study revealed that reduction of technical and commercial losses due to modernization of communal systems and implementation of energy-saving technologies can be achieved through efficient management via further development of public private partnership.

A necessary condition for a successful transition to a circular or closed economy is the creation of sufficient capacity for sorting and recycling of production and consumption waste. According to experts, annually more than 10 million tons of tires go out of use in the world, only in Russia every 4–5 years the increase in used tires will be about 2 million tons, which creates serious environmental and economic problems. This research is aimed at solving the problem of recycling accumulated and formed waste tires. The article provides a comparative analysis of tire recycling methods, proves the choice of pyrolysis method and estimates the environmental and economic efficiency of the project of a plant for processing used tires by pyrolysis.

We have considered the problem concerning the substantiation of sustainable development indicators and the improvement of the standard of living of the population in Russian regions. To quantify the standard of living of the population, we have used a common indicator such as the Human Development Index. The authors present an approach to managing the region in the form of optimization problems aimed at improving the standard of living of the region's population by increasing the probability of its classification as a region with a higher standard of living. The optimization problem is solved based on the identified relationship between the standard of living of the region's population and its socioeconomic indicators.

In this paper, the approaches to forecasting of passenger flows for new lines of the city railway are analyzed. The article analyzes the experience gained in designing of Moscow central diameters, in the modeling and analysis of their integration with the Moscow Metro and ground urban passenger transport. The main attention is paid to how modern telecommunication technologies make it possible to measure various movements of mobile subscribers, who are passengers, quite accurately. It is the development of telecommunication technologies that is changing the approaches to solving transport problems. What used to be seen as a goal for most transport tasks and was a forecasting goal has now become raw data and can be accurately measured. The article considers what the analysis of transport flows in a modern city now looks like.

Emissions of heavy metals into the environment lead to their accumulation in living organisms. This article presents the data on the accumulation of heavy metals in the fungi fruit in urban ecotopes of cities in the Western part of the Central Black Earth region. The features of accumulation of heavy metals by macromycetes of different taxonomic affiliation and ecological specialization under multi-level anthropogenic burden are studied. It was noted that MAC of Cadmium (Cd) in edible fungi can be in large excess over 88 times, lead (Pb) – 87 times, copper (Cu) – 6.8 times, zink (Zn) – 6.1 times. The accumulation of heavy metals by macromycetes can be determined by the degree of soil pollution, the bioavailability of heavy metals, as well as environmental specialization of fungi. The highest concentrations of heavy metals were recorded in the fruit bodies of soil and litter saprophytes. Cantharellus cibarius (L.), Murrill, Agaricus melleus (Vahl), Agaricus equestris L. were universal accumulators of Cd, Zn and Cu. Leccinum scabrum (Bull.) Gray, Kuehneromyces mutabilis (Schaeff.) Singer & A.H. Sm., Myxocollybia velutipes (Curtis) Singer are defined as selective Cd accumulators.

Some approaches to evaluating energy-efficient initiative budgeting projects are presented on the example of Yamalo-Nenets Autonomous district, the region of the Arctic zone of the Russian Federation. Formulas and an algorithm for evaluating the effectiveness of budgeting initiative project implementation to improve the energy efficiency of housing and communal complex are developed. An evaluation approach for energy efficiency of street lighting systems is proposed based on basic and optional criteria.

The article presents the concept of sustainable development of the Arctic zone of the Russian Federation through the sustainable development of the Northern Sea Route. A concept has been developed for the effective development of the Northern Sea Route and Arctic projects, and mechanisms are envisaged for their sustainable financing. The Russian programmes for the development of the Arctic region, the Transport Strategy of the Russian Federation, the Sustainable Development Goals of the United Nations, projects of state corporations were considered. The approach of sustainable development of the Northern Sea Route for sustainable development of the Arctic zone of the Russian Federation is proposed.

The abstract presents a critical review of the existing approaches to the assessment of the sustainability of the region that defines the development level of the social and economic system. The authors conducted the assessment of sustainability of the biggest region of Kazakhstan, Almaty oblast. The city of Almaty is a city of republican status and is not administratively part of Almaty oblast. The findings showed that in terms of dynamics the development of Almaty oblast as such is characterised as very close to being a sustainable one. Regardless of the fact that environmental and economic subsystems have shown stable growth, the social subsystem has features of instability.

Academic mobility is an important indicator of a country's competitiveness in innovations and research. Innovations play an important role for sustainable development as defined by UN 2030 goals. In this research we have studied how academic mobility is correlated with national economies.

Lockdowns imposed on population around the world due to COVID-19 provided unique opportunity to study impact of humankind of the environment. In this paper we discuss the magnitude of the anthropogenic impact on climate change, and in particular on-air pollution, since these two phenomena are interconnected. We used daily data on air pollution in several large cities, where serious restrictive measures were introduced in the context of a pandemic for a large number of citizens. The study period includes several months of 2020, including the moment of quarantine introduction, as well as the same period of 2019. Thus, we will check whether the impact of human activities on climate change is significant.
