2020 Common Alerting Protocol (CAP) Implementation Workshop Report
This page compiles the Report of the 2020 CAP Implementation Workshop together with the full set of presentations delivered during the event. The workshop took place 29–30 September 2020 (preceded by a CAP Training session on 28 September) and was hosted by the International Telecommunication Union (ITU) as a virtual workshop delivered via Zoom Webinars. The workshop was co-sponsored by IAEM, IFRC, OASIS, and WMO.
The 2020 workshop convened a large global community of policy and technical experts working on the Common Alerting Protocol (CAP) and multi-hazard early warning systems. Approximately 800 participants from 126 countries joined the training and workshop sessions, representing governments, international organizations, humanitarian actors, researchers, and the private sector. The list of Speakers includes speaker biographies, portraits and links to the presentations, and the list of Participants gives name, organizational affiliation, and e-mail address of each.
Across the presentations, speakers shared experiences and emerging practices related to interoperable, people-centred alerting, including national CAP implementations and profiles (Italy, Mexico, China, India), technological approaches to alert dissemination (cell broadcast, CAP feeds, MQTT, alert hubs, open-source tools), and global coordination and standards work through ITU, WMO, OASIS and partners. Several sessions highlighted how CAP-enabled systems support timely warnings for major hazard events—including earthquakes, floods, flash floods, cyclones, landslides, mudslides, wildfires and public health emergencies—while improving accessibility, multilingual delivery, and last-mile reach.
