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)?
