This report responds to a request from the Conference of the Parties at its twenty-fourth session to prepare, regularly update and publish before each session of the subsidiary bodies brief reports on standard costs and, if available, options for reducing the cost of activities where practicable. It should be read in conjunction with the first report in response to this request (FCCC/SBI/2019/INF.4), which was made available for consideration by the Subsidiary Body for Implementation at its fiftieth session. The first report includes an overview of standard costing practices in other parts of the United Nations system, as well as options for approaches to preparing and using standard costs for supporting decision-making in relation to new UNFCCC mandates under consideration by the governing or subsidiary bodies. This second report contains information on the costing of UNFCCC documents.
