For the UN 2030 Agenda, the goals were defined to eventually be achieved, but so far, each country has a different level of progress in this process. However, since the beginning of 2020, the world has been threatened by the COVID-19 pandemic. The pandemic has had widespread health and economic, political, and social effects. The COVID-19 pandemic was an unexpected and unforeseeable crisis for Organisation for Economic Co-operation and Development (OECD) countries. In this chapter, we use data envelopment analysis (DEA) to discuss how the COVID-19 pandemic has affected OECD nations’ ability to realise their SDGs. © 2024 selection and editorial matter, Erman Akilli, Burak Güneş and Ahmet Gökbel.eninfo:eu-repo/semantics/closedAccessBook Part10.4324/9781003377597-232-s2.0-85174083829
