During 2013, the UNDP-UNEP PEI built on the results of previous years in strengthening institutions through P-E mainstreaming. The PEI 2013 Annual Progress Report highlights the main achievements in 2013 reflecting a deepening of the ownership in PEI-supported countries. Such ownership is demonstrated by the increasing number of countries that are integrating P-E objectives into sector plans, policies, and monitoring and evaluation systems. This in turn has resulted in growing investments in and budget allocations for P-E objectives and climate change adaptation. The PEI efforts in 2013 reflect a growing recognition among partner countries that the P-E nexus remains a foundational element of greening economies.
