Cleaner Environmental Systems follows the path developed in Journal of Cleaner Production on the application of sustainability assessment tools including life cycle assessment, energy, exergy, techno-economic analyses and so on. These are rapidly growing reference tools to systematically examine the sustainability aspects of products, services or processes. The life cycle sustainability perspective involves the assessment of environmental/social/economic dimensions throughout the production systems, from the extraction of raw materials, through the production of goods, to the use of those goods and the management of the resulting waste. Life cycle sustainability assessment can support informed decisions, ecodesign and improvement actions to enhance sustainability, without burden shifting.Cleaner Environmental Systems aims to address a series of related topics and will include methodological advances in the environmental and sustainability assessment of processes and products from a holistic perspective. Subject areas include but not limited to: • Carbon footprint • Dematerialization and decarbonization • Ecodesign • Eco-efficiency • Environmental product declaration • Input-output analysis • Life Cycle Assessment • Life Cycle Costing • Life Cycle Management • Life Cycle Sustainability Assessment • Product Environmental Footprint • Product-oriented environmental policy • Water footprint • Techno-economic analysis • Circular Economy • Industrial Ecology • Urban Metabolism • Energy, Exergy Analysis • Industrial Symbiosis • Material Flow Analysis • Sustainable Energy Systems • Net ZeroWe encourage those interested in organizing a special issue or a virtual special issue within the scope of the journal to fill out this form and contact the editors-in-chief for more information.
