The EMG fosters ongoing dialogue on environmental issues at the highest levels within the UN system. At the technical level, it primarily operates through time-bound Issue Management Groups (IMGs) and Consultative Processes, each dedicated to specific environmental topics. 

These interagency working groups promote the exchange of knowledge and information among UN entities, developing strategic, unified approaches, system-wide mappings, gap analyses, joint statements, and implementation tools and guidance. 

This way, the EMG enhances coherence in the UN's support for Member States, optimize resource use, and strengthen the integration of environmental sustainability into the UN's policies, programs, and management practices.
