The Subsidiary Body for Implementation (SBI), at its eighteenth session, invited Croatia to submit, by 30 September 2003, inventories of anthropogenic emissions by sources and removals by sinks of all greenhouse gases not covered by the Montreal Protocol, by year, including data from 1990 or an earlier year to the latest inventory year available. The SBI also invited Croatia to submit projections of its greenhouse gas emissions consistent with inventory data. The secretariat has received a submission in response to the invitation above. In accordance with the procedure for miscellaneous documents, the submission is attached and reproduced in the language in which it was received and without formal editing. In this document only the executive summary of the inventory report and the full report of the projections are included. The full submission, including the full text of the inventory report and the projections report, is available at http://unfccc.int/resource/docs/natc/cronc1add.pdf
