The 2012-2013 biennium completed the implementation of the first Medium-Term Strategy of UNEP for the period 2010-2013. For the first time in the history of the organization, results-based management principles were fully applied throughout the programme cycle, from planning to monitoring and evaluating our implementation. UNEP’s performance against Expected Accomplishments in the Programme of Work for the biennium 2012-2013 shows: - 64 per cent achieved on schedule; - 85 per cent of indicator targets that were achieved were over-exceeded; - 30 per cent partially achieved with work still underway in some cases. Financial (and human) resources are not always available at the beginning of the biennium as funds are mobilized during the biennium in which results are to be achieved, sometimes affecting the pace of the organization’s delivery and expenditure rates; - 6 per cent not achieved, owing to indicators that were not possible to measure and were substituted with alternative performance measurements.
