The United Nations Committee for Development Policy has analyzed VNRs since 2017. Among other findings, it noted that very few VNRs describe adequate strategies for implementing Leave No One Behind (LNOB), a principle which is central to the 2030 Agenda. While most countries acknowledge it, VNRs often remain vague on how to implement LNOB in practice. Similarly, inequalities are often mentioned, but not addressed in detail. This VNR Lab will present these and related findings, highlight examples of emerging good practice, and discuss how they can be used for mutual learning for implementing the 2030 Agenda.
