Some remaining questions concerning the report - What volume of the report is planned? - How many pages are reserved for HMs and POPs chapter? - Will country-oriented information from MSC-E be included into national/regional assessments? - Who is responsible for section 3.4 (present pollution in relation to environmental targets)?
