The SBSTA, at its nineteenth session, requested the secretariat, subject to the availability of resources, to organize a workshop in the second half of 2004 on emissions projections of Parties included in Annex I to the Convention, as a contribution to the preparation of their fourth national communications (FCCC/SBSTA/2003/15, para. 14 (f)). The workshop would cover methods, assumptions, indicators, key parameters of models and sensitivity analysis, and dissemination of methodologies. The SBSTA invited Parties to submit to the secretariat, by 15 May 2004, their views on the workshop. The SBSTA requested the secretariat to prepare a report on the workshop for its consideration at its twenty-first session. The secretariat has received five such submissions. In accordance with the procedure for miscellaneous documents, these submissions are reproduced in the language in which they were received and without formal editing
