The new NDC also stresses the importance of an equitable and just transition, with particular emphasis on gender equality and social inclusion, children and youth, and people with disabilities.
- UNDP, in collaboration with UNICEF, UNFPA, and the Resident Coordinator’s Office (RCO) has played a pivotal role in offering both technical and financial assistance throughout the NDC process, helping strengthen national capacities and fostering inclusive stakeholder engagement.
