Philadelphia Meeting Cancellation
Registrants and Presenters
Safety is a core value of the American Chemical Society, and as such the health and well-being of our members, community and staff are paramount. As a result, we are cancelling (terminating) the ACS Spring 2020 National Meeting & Expo scheduled for March 22-26, 2020, in Philadelphia. 

Our decision was based on several factors, including, but not limited to:

  • The Governor of the Commonwealth of Pennsylvania signed an emergency disaster declaration as a result of the COVID-19 global outbreak and several COVID-19 cases have now been reported in the greater Philadelphia area.
  • Input received from Philadelphia city officials and continued review of recommendations from the U.S. Centers for Disease Control and Prevention (CDC) and other governmental bodies.
  • Watching the rapidly expanding trajectory of the COVID-19 virus using tools such as the Johns Hopkins Center for Systems Science and Engineering COVID-19 tracking system to monitor the ever expanding outbreak of COVID-19 domestically and globally.
  • Concern from our attendees and presenters, domestic and global, about safety of travel to and mass assembly in Philadelphia.

We want to assure all registrants that we will be issuing full refunds of fees. Further information will be available on the ACS Spring 2020 National Meeting & Expo webpage.


ACS meetings are complicated in size and scope to put together. A successful meeting involves thousands of hours of dedication from our volunteer organizers and staff. Disassembling a meeting will be no less challenging, and we ask for your support and patience as we address how best to accomplish this. Please visit the ACS Spring 2020 National Meeting & Expo webpage for additional details or reach out to us at NationalMeetings@acs.org.
