Sustainability Cover Letter: What Editors Actually Need to See

The official Sustainability pages describe the MDPI submission workflow and list section scopes, but they do not prescribe a specific cover-letter format.

What the journal model does imply is clear:

• the manuscript should connect to sustainability in a substantive way, not just mention the word
• the editor needs section routing information immediately
• the letter should reduce friction in a very high-volume editorial workflow

That means section selection and scope clarity matter more here than at almost any other MDPI journal, precisely because the scope is so wide.

At triage, the academic editor is usually asking:

• does this paper have a real sustainability dimension, or does it just use the word in the title?
• does it fit the section the author selected?
• does the submission look complete enough to send to reviewers without administrative delays?
• is the contribution clear enough to justify review at a broad-scope journal?

A cover letter that answers these questions in the first few sentences clears triage fastest.

According to the official MDPI instructions and section structure, the letter does not have to be ornate. It has to reduce routing ambiguity. In practice, that means a better Sustainability letter does three concrete things early:

• names the section or subject lane explicitly
• explains the actual sustainability problem the manuscript addresses
• shows that the paper contains a substantive result rather than a generic policy or management discussion

That matters because Sustainability handles an unusually broad submission mix. Editors are not trying to decode whether a paper is really about resource systems, environmental assessment, education, planning, energy transition, or corporate sustainability after reading three paragraphs of generic framing. They want the answer immediately.

The practical implication is simple: the first paragraph should do section routing work, not just persuasion work.

Editors actually slow down when the letter never commits to one lane. We see this pattern when authors use the word "sustainability" repeatedly but never say whether the paper is an energy-systems study, a waste-management paper, a life-cycle assessment, or a social-sustainability analysis.

What actually happens at triage is a scope-and-section check before a novelty debate. In our review work, the strongest letters tell the editor exactly where the paper belongs and what concrete sustainability conclusion the data support. The weakest letters sound interchangeable with dozens of other broad-scope submissions.

This is where technically solid papers create avoidable friction. If the manuscript has a real result but the letter stays generic, the editor has to infer the fit alone. That is the wrong place to create work in a high-volume journal.

• never naming the target section in a journal with dozens of possible sections
• using generic sustainability rhetoric without stating a specific finding
• submitting a paper from another discipline and adding the word "sustainable" to the title
• making the letter too long for a high-volume MDPI editorial workflow
• failing to state which dimension of sustainability (environmental, social, economic) the paper addresses

These mistakes slow triage or trigger desk rejection.

Before polishing the letter further, confirm the journal fit. Sustainability is broad but still requires a genuine sustainability dimension, papers that belong in a disciplinary journal and have only a superficial sustainability framing will struggle regardless of letter quality. Check the journal's own author guidelines and browse recent papers in your target section to verify alignment.

The strongest Sustainability cover letters are short, section-specific, and sustainability-focused. They tell the editor where to route the paper and what the sustainability finding is.

So the useful takeaway is this: name your section, state the sustainability result, and keep the letter operationally clean. A Sustainability cover letter framing check is the fastest way to pressure-test whether your framing already does that before submission.

• Generic prestige language. "We are submitting to Sustainability because of its high impact factor" tells the editor nothing about fit. Name the specific reason.

• Repeating the abstract. The cover letter should explain why here, not what we did. The editor will read the abstract separately.

• Missing required declarations. Check Sustainability's author guidelines for specific disclosure requirements. Missing these can trigger an immediate desk return.

• Overselling the findings. Editors are experts. Claims like "major" or "paradigm-shifting" without supporting evidence in the paper undermine credibility.
