Sharing economy platforms transform traditional production and consumption systems in cities around the world. While the sharing economy aims to increase the resilience of different economic systems, its actual economic, social, and environmental effects remain under-researched. During the pandemic of Covid-19, economic and environmental crises, and growing uncertainty, it becomes essential to promote sustainable and promising forms of shared (distributed) resources. Ways to benefit from the sharing economy's advantages, despite the significant number of Russian and foreign publications, are still poorly understood. At present, it is crucial to explore the roles, perspectives, and effects of both resource owners and users and Russian interaction platforms. Let us look at this sharing economy's development aspect on the example of the Moscow real estate market, taking into account the environmental impact of the large-scale housing renovation program. There have been identified some digital environmental IT platforms aimed at improving the efficiency of transfer and use of information resources (the main principle of sharing - to improve the efficiency of resources and information, in this case - environmental) on the environmental situation in Moscow and the region to inform the public about the opportunities and the primary environmental risks in housing purchase or construction. © The Authors, published by EDP Sciences, 2020.
