  • Attendee List Scam

    The American Chemical Society does not sell email lists of members or meeting registrants. Distribution or other use of the list without ACS’ express authorization is strictly prohibited. Third party “pirate” companies reach out to delegates and exhibitors offering to sell these lists often with the primary objective of obtaining credit card information. ACS is aware that these solicitations occur but has no affiliation with these companies. Please email the Meetings Team with any questions or concerns.

Attending Sessions

  • Recording Policy

    No Image Capturing or Recording Please 

    The capturing of images, sounds, or stream, downloading, or rebroadcasting of technical session (oral or poster) speakers or presentations is strictly prohibited within the ACS meeting platform.

  • ACS Meeting Attendee Conduct Policy

    American Chemical Society (ACS) convenes events and meetings that are welcoming, respectful, inclusive, and collaborative. ACS's Meeting Attendee Conduct Policy applies to all ACS-sponsored events, as well as affiliated events connected with an ACS meeting or event, whether in public or private facilities.

    All ACS Meeting Attendees Must Comply with the ACS Volunteer/Meeting Attendee Conduct Policy. It provides:

    One of the key strengths of the ACS has been the enduring and varied contributions made by its thousands of dedicated volunteers. 

    Another unassailable strength of the ACS is its outstanding meetings program. ACS meetings are among the most respected scientific meetings in the world. ACS meetings offer scientific professionals a legitimate platform to present, publish, discuss, and exhibit the most exciting research discoveries and technologies in chemistry and its related disciplines. Furthermore, ACS meetings facilitate networking opportunities, career development, and placement, and provide organizations with opportunities to exhibit products and services to targeted audiences. 

    The Society’s Congressional Charter explicitly lists among its objectives “the improvement of the qualifications and usefulness of chemists through high standards of professional ethics, education, and attainments....” The ACS expects its volunteers and meeting attendees to display the highest qualities of personal and professional integrity in all aspects of their ACS related activities. Indeed, every chemical professional has obligations to the public, to volunteer and staff colleagues, and to science. 

    Accordingly, and to foster a positive environment built upon a foundation of trust, respect, open communications, and ethical behavior, the ACS Board of Directors has issued this Conduct Policy. It applies to ACS Volunteers, i.e., it applies to individuals conducting the business and affairs of the ACS without compensation for that conduct. It also applies to attendees at ACS meetings. Volunteers and meeting attendees should at all times abide by this Conduct Policy. Specifically: 

    1. Volunteers should understand and support ACS’s vision and mission. 
    2. Volunteers and national meeting attendees should contribute to a collegial, inclusive, positive, and respectful environment for their fellow volunteers and attendees, as well as for other stakeholders, including national meeting vendors and ACS staff. 
    3. Volunteers and meeting attendees must avoid taking any inappropriate actions based on race, gender, age, religion, ethnicity, nationality, sexual orientation, gender expression, gender identity, marital status, political affiliation, presence of disabilities, or educational background. They should show consistent respect to colleagues, regardless of the level of their formal education and whether they are from industry, government or academia, or other scientific and engineering disciplines. 
    4. Volunteers and meeting attendees should interact with others in a cooperative and respectful manner. Volunteers and meeting attendees should refrain from using insulting, harassing, or otherwise offensive language in their ACS interactions. Disruptive, harassing, or inappropriate behavior toward other volunteers, stakeholders, or staff is unacceptable. Personal boundaries set by others must be observed. Harassment of any kind, including but not limited to unwelcome sexual advances, requests for sexual favors, and other verbal or physical harassment will not be tolerated. 
    5. Volunteers must obey all applicable laws and regulations of the relevant government authorities while acting on behalf of the ACS. Likewise, meeting attendees must obey all applicable laws and regulations of the relevant government authorities while attending ACS meetings. Volunteers and meeting attendees alike should also ensure that they comply with all applicable safety guidelines relating to public chemistry demonstrations. 
    6. Volunteers and meeting attendees should only use ACS’s trademarks, insignia, name, logos, and other intellectual property in compliance with ACS regulations and directives as may be issued from time to time. 
    7. Violations of this Conduct Policy should be reported promptly to the ACS Secretary and General Counsel or to the Chair of the ACS Board of Directors. In cases of alleged persistent and/or serious violations of this Conduct Policy, the Board shall review the evidence and shall take such actions as may be appropriate, including but not limited to requiring volunteers to leave their volunteer position(s); precluding volunteers from serving in Society volunteer roles in the future; requiring meeting attendees to leave the meeting; and precluding meeting attendees from attending future ACS meetings. ACS, through its Board of Directors, reserves the right to pursue additional measures as it may determine are appropriate. 


  • Technical sessions, either oral or poster

    1. Their presentation is the original work of the presenter and any contributors who have been involved in such research or preparation have been appropriately identified. 
    2. Any third-party quotations or figures have been appropriately noted, and in the case of illustrations in particular, permission for their use has been obtained.     
    3. All institutional approvals and protocols have been obtained and followed in conjunction with the research and the preparation of the presentation. Similarly, any related requirements of relevant research funding agencies have been followed.  Any funding agencies providing support for the underlying research have been identified.
    4. Any unusual hazards inherent in the chemicals, equipment or procedures used in the underlying research as described in the presentation are clearly identified.

  • Statement on Diversity, Equity,  Inclusion And Respect

    Statement on Diversity, Equity,  Inclusion And Respect

    The American Chemical Society aspires to be a diverse, equitable, inclusive and respectful community of highly skilled chemical professionals.

    We encourage inclusivity and oppose discrimination in scientific learning and practice based on - but not limited to - race, religion, country or ethnic origin, citizenship, language, political opinion, sex, gender identity and expression, sexual orientation, disability, age, and economic class in academic, industrial, and government workplaces. The Society believes that an enduring commitment to diversity enables excellence, innovation, and transformative action in current and future generations of chemical professionals.

    As a global scientific society, we affirm the international principles that the responsible practice of science, free from discrimination in all of its forms, is fundamental to scientific advancement and human wellbeing, as outlined by the International Council for Science’s (ICSU) Statute 51.

    We also affirm our commitment to a scientific environment that facilitates the execution and communication of scientific work with integrity, fairness, and transparency at all organizational levels. This extends to our general scientific endeavors—including our professional interactions and engagement with other scientists, trainees, and the general public. We recognize that harm to our profession, our scientific credibility, individual wellbeing, and society at large is caused by not doing so.

    To this end, the Society will implement the principles of diversity, inclusivity, and equity within ACS leadership and membership to build a community across the chemical enterprise. We are committed to quantifying and monitoring our diversity.
