Peer review policy

UCL Open: Environment operates an open and transparent peer review process where readers can assess the peer reviewer reports as part of the article’s review history. Articles submitted to the journal are first posted to the preprint server to undergo open peer review before being published officially in the journal after editorial acceptance. 

Important note: all preprint articles are declared as not yet peer reviewed.

UCL Open Environment requires at least two external peer reviews of a submitted article to be made openly available online before an editorial decision for official publication in the journal can be made. As far as possible, assigned editors and invited reviewers will not possess any potential conflicts of interests to the submitted article. However, where this is not possible, in circumstances where specific and required expertise or other reasons that are deemed necessary, any decision to publish may require additional review to maintain fair review practice. The journal Editor may also decide to reject a review after considering any and all conflicts of interest and the reviewer will be informed of this decision. The Editor’s decision is final.

Who can review for UCL Open: Environment?

Reviewers are invited by the Editor based on subject expertise. In addition, as the journal operates open peer review (the names and affiliations of reviewers are published alongside their review reports), authors are also encouraged to help expedite the peer review process by inviting reviewers to review their paper openly. 

As a general guide, peer reviewers should hold expert knowledge of the specific disciplines to which your article relates. For example, it is usual for many peer reviewers to hold a doctorate (PhD/MD/MBBS or equivalent). In subjects or fields where doctorates are less common or reviewers are currently in process of completing one, we recommend these individuals provide via their ORCID profile a demonstrable public record of expertise.

If you are interested in reviewing for the journal and wish to register your interest with the journal Editors, please contact the editorial office with your details and subject expertise by emailing

Reviewers invited by authors are required to have five published records associated with their ORCID to demonstrate that reviewers are active and professional researchers. Any professional or researcher who would like to review a paper but has fewer than five published records associated with an ORCID is advised to contact the editorial office to register their interest in reviewing a paper.

Ethical obligations of reviewers

To ensure the highest quality research in UCL Press publications, reviewers are expected to uphold the following when reviewing:


  1. Provide clearly written, unbiased feedback in a timely manner on the scholarly and/or scientific merits and value of the work, together with a documented basis for the reviewer’s opinion. Judge the paper on its merits without regard to personal bias, ethnic origin, race, religion, citizenship, language, political or other opinion, gender, gender identity, sexual orientation, disability, appearance, age, or economic class, seniority, or institutional affiliation of the author(s).
  2. Thoroughly address all review criteria provided by the journal.
  3. Decline to review manuscripts for which the reviewer lacks sufficient time, is not qualified, or has a conflict of interest with any of the authors, including personal or competitive relationships.
  4. Explain and support judgments adequately so that Editors and authors may understand the basis of their comments. Any statement by a reviewer on an observation, derivation or argument that has been previously published should be accompanied by the relevant citation.
  5. Provide citations to relevant work by other scientists as appropriate.
  6. Alert the Editor to any significant similarity between the manuscript under consideration and any other published paper or manuscript submitted concurrently to another journal. Report any plagiarism or the appearance of plagiarism.
  7. Never use or disclose unpublished information, arguments or interpretations contained in a manuscript under consideration, except with the consent of the author.
  8. Never include personal criticism of the author in reviewing a manuscript.

Code of conduct

UCL Open: Environment aims to provide a safe, open, and professional environment for learning and communicating research with integrity, respect, fairness, trustworthiness, and transparency. Open debate and commenting are an important aspect of the scientific endeavour to encourage constructive criticism and high quality discussions of scientific issues that will both enhance understanding and provide new avenues of collaboration within the community.

Reviews and/or comments will be monitored to ensure that they contribute to the scholarly debate. Any reviews and/or comments that appear to be advertising, potentially libellous or legally problematic (including comments revealing any personal and/or sensitive information) will not be published. The Editors of the journal will not accept comments that are offensive, indecent or contain negative comments of a personal, racial, ethnic, sexual orientation or religious character. All comments must be written in good English; a comment may be rejected if it is deemed unintelligible. 

While we welcome open scholarly debate and discussion, we will not tolerate abusive behaviour towards our authors and reviewers via our Comment system or via social media. In extreme cases we will consider contacting the affiliated institution to report the abusive behaviour of individuals.
