The Sustainable Development Report 2020 features the SDG Index and Dashboards, the first and widely used tool to assess country performance on the UN Agenda 2030 and the Sustainable Development Goals. The report shows that all countries need to strengthen the resilience of their health systems and prevention programs. Some countries have outperformed others in containing the Covid-19 pandemic, yet all remain at serious risk. The report frames the implementation of the SDGs in terms of six broad transformations. The authors examine country performance on the SDGs for 193 countries using a wide array of indicators, and calculate future trajectories, presenting a number of best practices to achieve the historic Agenda 2030. The views expressed in this report do not reflect the views of any organizations, agency or programme of the United Nations. This title is available as Open Access on Cambridge Core.
