The performance of the UN Environment Programme (UNEP) over the first twelve months of the biennium 2010‐2011 is captured in this report. The report summarizes UNEP’s progress towards the results planned in the UNEP Medium‐Term Strategy (2010‐2013) and the Programme of Work for the biennium 2010‐2011. This period of performance monitoring (January‐December 2010) continued to be a phase of transformational change for UNEP as the organization began implementing a results‐based Medium‐Term Strategy and Programme of Work. UNEP’s programme performance monitoring is a key step in this transformational change within the organization. It enables progress to be monitored against the results planned for the biennium. It also enables management to know where corrective action is necessary and who is accountable for taking action.
