Make your research freely available to readers around the world
What is Open Access?
Open access is one of the core elements of open science, making research articles openly and freely available to anyone who seeks to access, read, and build upon it. This is typically facilitated by article publishing fees, which in most cases are paid for by an author’s research grant, a research funder, or through an institutional open access agreement.
Open access research articles published in ACS journals are subject to the same rigorous peer review and high publishing standards as all our content.
There are two common paths to make your articles available in open access: the ‘gold’ and ‘green’ routes.
How can I publish open access with ACS?
ACS publishes a family of fully open access journals containing 100% free-to-read articles, and more than 60 Transformative Journals which offer authors the choice to publish open access.
We provide multiple ways you can make your research articles available via open access:
- With support from your institution or research funder through a Transformative Agreement;
- CC BY and CC BY-NC-ND open access options for authors who are not currently covered by an ACS transformative agreement, including those publishing using grant or personal funds;
- Deposition of the version of record in selected national and funder open access repositories after a 12-month embargo period.
Selected articles may also be made free to read for a limited time underneath the ACS Editors’ Choice program.

What’s the difference between Gold and Green open access?
Gold open access involves making the final published article (the ‘version of record’) immediately available online, with no charges for readers, upon payment of an article publishing charge (APC).
Green open access involves archiving a version of the manuscript (usually the version prior to any peer review or typesetting) in an institutional or subject repository. This often happens after a set amount of time from when the article is published in a journal (an ‘embargo period’). Authors who publish a Gold open access article can also choose to archive the version of record in a repository immediately upon publication.
There are other differences between Green and Gold OA:
|Gold OA||Green OA|
|Published in:||Fully open access or transformative journal||Subscription or transformative journal|
|Embargo:||None||12 months after first publication in a journal|
|Creative Commons License:||CC BY or CC BY-NC-ND||None required|
|Publishing Fees:||APC paid by an author, research funder, or institution (often under a ‘Transformative Agreement’)||No fee|
How can I make an existing ACS article open access?
Whether you need to meet a funder mandate, or you want to make your previously-published research articles more widely available, ACS Author Choice gives you the option to apply an open access license to your research article. Find out more.
