In response to Resolution 2/7 from the second session of the United Nations Environment Assembly (UNEA) and reaffirmed in Resolution 4/7 from its fourth session, the Global Waste Management Outlook offers an updated assessment of global waste management and an analysis of data concerning municipal solid waste management worldwide. Jointly published with the International Solid Waste Association (ISWA), the report evaluates three potential scenarios of municipal waste generation and management, examining their impacts on society, the environment, and the global economy. Furthermore, it presents potential strategies for waste reduction and enhanced management, following the waste hierarchy, to treat all waste materials as valuable resources.
