Implementation as of 2016 is described as "Localizing the SDGs" to highlight the role of local institutions and local actors. Regional efforts included agreements like the Baltic 2030 Action Plan. Some remain pessimistic about the potential for achieving the SDGs, especially because of estimates of the cost of achieving all 17 and how far away the world currently is on key goals. However, progress had been reported by 2018. According to a study published in Nature fewer African children under the age of 5 are suffering from stunting and wasting. Key to making the SDGs successful is to make the data on the 17 goals available and understandable. To track progress towards the goals and see where the world currently stands the University of Oxford publishes the SDG-Tracker.
