Brownfields, Environmental Stability and Renewable Energy: Pathways to Overcome the Imperfection of Cumulative Effect Assessment

Brownfields or objects of accumulated environmental damage are a complex object characterized by both the absorption and release of uncontrolled energy (for example, biogas or hydrothermal energy). The brownfield redevelopment process provides unique opportunities to ensure efficient energy transfer and maintain environmental stability. However, the implementation of these solutions depends on the quality of the assessment of the cumulative impact of unspent deposits, namely, the assessment of the damage caused to the environment, which, in turn, gives an understanding of how to ensure the elimination of damage to energy efficiency and environmental safety from uncontrolled carbon dioxide emissions. In this article, we consider the problems of assessing the cumulative effect of waste management activities, as a result of which abandoned deposits or objects of accumulated environmental damage appear. A cycle of measures to achieve socio-economic efficiency through the re-development of brownfields and their integration within energy-efficient systems and environmentally balanced systems is proposed, and a new concept of identifying the negative occurrence of brownfields under the influence of climate change is substantiated. Particularly, we assess the possibilities of integrating brownfields or objects of accumulated environmental damage into energy-efficient and environmentally balanced systems for goals of sustainable development.
