Sustainability, ESG and human rights roles have multiplied over the past few years, and demand shows little sign of settling as regulatory obligations such as the CSRD and incoming due-diligence rules push these functions further into the mainstream. Yet many employers report the same quiet frustration: healthy application numbers, disappointing shortlists.
When high response rates keep producing weak candidates, the problem is often rooted in the job advert. This is the first and most public statement of what a role actually is, and small ambiguities in wording translate into large mismatches in who applies. Below are four common reasons sustainability adverts pull in the wrong people, and what to change.
1. Your advert describes an aspiration, not a job
Sustainability adverts are unusually prone to mission language. Phrases like “passionate about building a greener future” or “help us drive meaningful change” describe a worldview, not a role. They tell a candidate almost nothing about what the work involves on a Monday morning, which frameworks they will apply, or what they will be accountable for delivering. The people most excited by that language are often those who share the values but have yet to develop the craft. Meanwhile, experienced practitioners scan for substance, find little, and move on to a posting that respects their time.
The fix: Lead with concrete responsibilities and deliverables. Name the frameworks and standards the role will work with, the outputs it owns, and the teams it will work alongside. Aspiration can stay, but it belongs in a supporting line, not as the substance of the advert.
2. You have asked for a unicorn
Sustainability is a broad field, and it is tempting to write a specification that covers all of it. A single advert may ask for environmental science, carbon accounting, human rights due diligence, legal interpretation, data analytics and board-level communication, all at depth. Very few people hold that combination, and the ones who genuinely do are rarely on the market. The candidates who apply anyway tend to be generalists who are confident across everything and expert in nothing, precisely because a specialist reads the same list and assumes the role has no real focus.
The fix: Decide what the role is actually for and define its core discipline. Separate genuine must-haves from useful nice-to-haves, and be explicit about which is which. A focused specification signals that the work has depth, which is exactly what serious specialists are looking for.
3. The role signals no real mandate
Capable sustainability professionals have learned to read between the lines, and the advert reveals more about a role’s influence than employers realise. A position that reports into communications, sits several layers below the leadership team, or is framed entirely around reporting outputs rather than decisions, reads as symbolic. The strongest operators, who want the authority to change how an organisation actually behaves, quietly screen themselves out. What remains is a pool weighted toward people drawn to the title rather than the mandate, which is the opposite of what most employers intend.
The fix: Be honest and specific about where the role sits. State the reporting line, the decisions it can influence, any budget it holds, and how its success will be measured. If the mandate is genuinely limited, say so plainly rather than dressing it up, so the people who apply are the ones suited to the role as it really is.
4. You are screening for passion over proof
Because sustainability is values-driven work, adverts often place enthusiasm at the very top of the requirements. "A genuine passion for sustainability" as the headline criterion sends a clear signal about what will be assessed, and it invites a flood of career-switchers and rebadged CVs from people who have added the language of the field without the substance. Passion matters, but it is necessary rather than sufficient, and it is also the easiest thing in the world to claim. When it dominates the advert, the harder-to-fake evidence of capability gets crowded out.
The fix: Specify the demonstrable capabilities the role requires and the evidence you will look for, such as having led a Scope 3 data-collection programme or run a supplier due-diligence process. Naming the proof you expect does two things at once: it attracts people who can point to it, and it gently discourages those who cannot.
The common thread
A good sustainability advert does two jobs at the same time: it draws the right people in and quietly filters the wrong ones out. 'Good' does not necessarily mean reams of detail; it's about writing more precisely, trading aspiration for specifics, breadth for focus, and passion for proof.
The reward is a shorter but stronger shortlist, and far less time spent screening out mismatches you invited in. In a field where the right hire can shape how an organisation meets its obligations and commitments, the quality of the advert should never be underestimated.
