Why pre-screen environmental economics consultants before the interview
A valuation of something with no market price is only as good as its method and its assumptions, and both are easy to choose in a direction that suits whoever commissioned the work. Consultants worth hiring state the discount rate, the transfer assumptions and the range around a central estimate, and have produced a number a client did not want. A short screen asks for that range.
What actually matters when screening Environmental Economics Consultant candidates
- 01
Method and rigour
Check command of non-market valuation: contingent valuation, choice experiments, hedonic pricing, benefit transfer, plus discounting choices and Green Book or ENCA appraisal conventions they applied.
- 02
Real casework
Probe named appraisal work: flood scheme business cases, carbon shadow pricing, water company PR periods, biodiversity net gain assessments. Ask project scale, client, and how findings were used.
- 03
Interpretation and judgement
Test how they handle uncertainty: sensitivity analysis, Monte Carlo ranges, optimism bias uplifts, and distributional effects when benefit-cost ratios sit near one.
- 04
Reporting and testimony
Assess written and oral delivery: technical annexes, non-technical summaries, defending assumptions to regulators, planning inspectors, or Defra and Environment Agency reviewers.
Pre-screening questions to ask Environmental Economics Consultant candidates
12 questions grouped by what they test. Ask the same set in every screen and score answers on a consistent scale, or send them as an async video screen and compare answers side by side.
Analyses that landed
3 questions01Can you give an example where you advised on a policy change and it was adopted?
Listen forA specific policy or decision that changed, with what the analysis showed and who acted on it.
Reports delivered with no decision attached, or influence claimed with no example to point at.
02Can you describe your experience with cost-benefit analysis on environmental projects?
Listen forAppraisals they authored, with the discount rate stated and its effect on the conclusion acknowledged.
Discount rate chosen without justification, or its effect on the result never tested.
03What is your experience with impact assessment from an economic perspective?
Listen forEconomic chapters they wrote within a formal assessment, with the consenting regime named specifically.
Contribution limited to compiling other people's figures, or no formal assessment they worked on.
Method and assumptions
4 questions04Can you discuss your experience with non-market valuation techniques?
Listen forTechniques applied with their known biases acknowledged, and the survey or revealed data described.
Techniques named without application, or known biases in stated preference work not mentioned.
05How do you assess the economic value of ecosystem services?
Listen forServices valued selectively where the evidence supports it, rather than every service given a number.
Comprehensive valuations produced for everything, or double counting between services not addressed.
06How do you approach life cycle cost analysis on environmental projects?
Listen forWhole-life costs including maintenance and decommissioning, with the time horizon justified explicitly.
Analysis stopping at capital cost, or a time horizon chosen because it flatters the result.
07Can you give an example of using statistical analysis to support your consultancy work?
Listen forMethods matched to the data available, with the limitations of observational evidence acknowledged clearly.
Causal claims from observational data, or statistical significance treated as economic importance.
Uncertainty carried
2 questions08How do you handle uncertainty and variability in environmental economic modelling?
Listen forSensitivity analysis run on the parameters that matter, with the range reported alongside the central figure.
Single point estimates reported, or sensitivity analysis run but left out of the summary.
09What methods do you use to evaluate the economic impact of environmental regulation?
Listen forCosts and benefits both estimated, with distributional effects across sectors and groups considered.
Only compliance costs estimated, or distributional effects treated as outside the analysis.
Holding a position
3 questions10Describe a time when you argued for environmental considerations in a commercially driven project.
Listen forA position held with evidence when it was commercially unwelcome, with what they conceded stated.
Findings softened under client pressure, or no analysis that produced an unwelcome result.
11How do you communicate complex economic concepts to varied audiences?
Listen forFindings expressed as decisions and trade-offs, with the uncertainty retained in the executive summary.
Caveats dropped for senior audiences, or explanations built on economic terminology.
12How do you engage communities and reflect their economic interests in your work?
Listen forLocal economic effects assessed directly with affected groups rather than inferred from regional statistics.
Local impacts inferred from aggregate data, or affected communities never consulted.
How to score responses
Score every candidate on the same four criteria immediately after the screen. At this stage you are shortlisting for panel interviews, not making the final call.
Method and rigour
35%5Names the exact valuation method per study, defends discount rates and welfare weights, and knows where benefit transfer breaks down.
Real casework
25%5Cites specific commissions with budgets, data sources, and decisions the appraisal shaped, including work that was challenged or revised.
Interpretation and judgement
25%5Separates robust results from fragile ones, quantifies uncertainty explicitly, and states plainly when evidence cannot support a recommendation.
Reporting and testimony
15%5Produces appraisals that survive peer review, explains discounting to lay audiences, and holds position under cross-examination without overclaiming.
A valuation with no market price is only as good as its assumptions, which are easy to choose. A one-way video screen asks for the range.

Process basics
How long should a pre-screening round for this role take?
Fifteen minutes across eight to ten questions, answered async. Enough to establish analyses that changed decisions, test their valuation method, and check how they handle uncertainty.
How much does policy experience matter?
Considerably. An analysis that never reaches a decision-maker changes nothing, and knowing what a policy team can actually use shapes how the work is framed from the start.
Evaluating answers
What is the strongest signal when screening this role?
A range rather than a point estimate. Consultants doing rigorous work state uncertainty as a matter of habit. Anyone quoting a single confident figure for a non-market value is overstating.
How do I judge their independence?
Ask about a result a client did not want. Real answers describe delivering it with the evidence. Anyone whose analyses always supported the commissioning position is a professional risk.
