In order to support States Parties in better understanding and adhering to the ATT’s reporting requirements – as well as inform key stakeholders of current challenges to and trends in ATT reporting – the Stimson Center has created reporting factsheets that provide insights into ATT reporting obligations, the current status of reporting, and challenges that hinder States Parties’ reporting efforts. Each factsheet is intended to serve as an informative resource for States, the ATT Secretariat, the CSP Presidents, the Working Group on Transparency and Reporting, and non-government stakeholders to strengthen ATT reporting and support effective treaty implementation.
