This paper present a new methodology using machine learning designed to link project-based flows to the Sustainable Development Goals. It provide first estimates of DAC and non-DAC donors’ aid contribution for the goal and show that similar analysis can be done at the recipient level and for other type of textual database such as private sector reports; opening wide array for policy analysis.The methodology presented in this working paper uses semantic analysis of the text description of each project present in the Creditor Reporting System (CRS).
