The joint UNDP-UN Environment National Adaptation Plan Global Support Programme (NAP-GSP), funded by the Global Environment Facility (GEF), assists least developed and developing countries to identify technical, institutional and financial needs to integrate climate change adaptation into medium and long-term national planning and financing. 

The programme supports the process to formulate and implement National Adaptation Plans (NAPs) under the UN Framework Convention on Climate Change (UNFCCC). In doing so, the NAP-GSP works with development partners to implement the Nationally Determined Contributions and promotes ambitious climate action in alignment with the Sustainable Development Goals. 

The NAPs process was established under the Cancun Adaptation Framework (2010) in order to prepare countries for addressing climate risk in the medium term. The main objectives of the NAPs are to reduce vulnerability to climate change, and to mainstream climate change adaptation in all levels of planning.  The NAPs are not a one-off investment. The process is intended to be continuous, progressive and iterative. NAPs require building a stronger evidence base, improving skills and capacity and adopting learning by doing approaches. NAPs need to be country-driven, gender-sensitive, participatory and use transparent approaches.
UNDP and UN Environment have been supporting developing countries on NAPs through the NAP-GSP since 2013, through a portfolio of initiatives in partnership with development partners.
The main areas of work are:
1) Assisting countries to think through what it means to integrate climate into planning and budgeting and develop a plan of action that specifies what needs to be done and resources required.
2) Providing in-country and virtual support on stocktaking of capacity gaps and needs as well as of ongoing adaptation plans and activities to identify entry points for NAP support. UNDP and UN Environment - together wth programme partners - training on  the NAP process for multi-stakeholder groups; economics of adaptation; and understanding climate information in the context of development planning
3) Assisting countries to integrate vulnerable sectors, thematic areas, sub-national approaches and legal issues into adaptation planning and budgeting by supporting sectoral and cross-sectoral stock-taking, assessments and application of appropriate tools and guidelines.
