Evaluate Carbon Accounting Specialist candidates across 4 weighted areas: technical command, deals and deliverables that closed, risk judgement, and explaining it to decision-makers. Technical command leads at 35%, so test command of the GHG Protocol Corporate Standard: Scope 2 market versus location based dual reporting, Scope 3 category selection, emission factor sources. Use the rubric to compare role-specific evidence consistently.
For technical command, look for evidence the candidate names specific Scope 3 categories they calculated, defends factor choices and activity data hierarchies, and explains recalculation triggers without hedging. For deals and deliverables that closed, look for evidence the candidate cites named disclosures with tonnes CO2e, reporting boundaries, assurance provider and specific findings they closed out.
Apply the written 1–5 anchors to every answer, record the evidence behind each rating, and use the factor weights to reach a consistent overall assessment.

What to assess and how to score it
Review the evidence signals before interviewing. Then use the anchored descriptions—not instinct alone—to choose the score that best matches each answer.
01
Evaluation factor
Technical command
35% weight
Test command of the GHG Protocol Corporate Standard: Scope 2 market versus location based dual reporting, Scope 3 category selection, emission factor sources (DEFRA, EPA, ecoinvent) and base year recalculation rules.
Evidence to listen for
Commands the instruments, models, or reporting standards the role turns on
Can build the analysis rather than only interpret someone else's
Knows the assumptions inside a model and which ones actually drive the answer
Fluent in the frameworks and disclosure regimes that apply
Five-point scoring guide
1
Poor
Cannot explain the instruments or standards they claim to work with.
2
Needs Improvement
Interprets others' analysis but cannot build or defend it.
3
Satisfactory
Solid working command; thin on unfamiliar structures or standards.
4
Very Good
Builds the analysis and knows which assumptions actually move the answer.
5
Excellent
Names specific Scope 3 categories they calculated, defends factor choices and activity data hierarchies, and explains recalculation triggers without hedging.
02
Evaluation factor
Deals and deliverables that closed
25% weight
Ask for inventories they built end to end: annual footprints signed off, CDP or CSRD submissions filed, SBTi targets validated, or limited assurance passed under ISAE 3000.
Evidence to listen for
Names transactions, filings, or reports they worked, with size, counterparties, and their own scope
Distinguishes their contribution from the deal team's
Knows what happened afterwards, including what underperformed
Can describe one that fell over and why
Five-point scoring guide
1
Poor
No completed work; describes process rather than outcomes.
2
Needs Improvement
Involved in transactions but cannot state their own scope.
3
Satisfactory
Real deliverables with adequate ownership; outcomes described loosely.
4
Very Good
Named transactions or filings with clear personal scope and honest post-mortems.
5
Excellent
Cites named disclosures with tonnes CO2e, reporting boundaries, assurance provider and specific findings they closed out.
03
Evaluation factor
Risk judgement
25% weight
Probe how they handle data gaps, spend-based proxies, supplier estimates and double counting, plus where they flag greenwashing exposure in offset or renewable energy claims.
Evidence to listen for
Distinguishes a modelled risk from a real one
States confidence and what would change their view
Comfortable disagreeing with a number that suits everybody
Knows the limits of the data behind a projection, especially over long horizons
Five-point scoring guide
1
Poor
Treats model output as truth; no sense of data limits.
2
Needs Improvement
Reports numbers without qualifying them; avoids unwelcome conclusions.
3
Satisfactory
Reasonable judgement; qualifies findings when prompted.
4
Very Good
States confidence unprompted and will hold an unpopular position on evidence.
5
Excellent
Distinguishes defensible estimation from unsupportable claims, documents uncertainty, and has pushed back on a marketing or offset claim.
04
Evaluation factor
Explaining it to decision-makers
15% weight
Judge how they brief CFOs, procurement and sustainability committees: turning inventory results into decarbonisation levers, internal carbon price inputs, or supplier engagement plans.
Evidence to listen for
Explains a technical position to an investment committee, board, or regulator so they can act on it
Writes to the standard the audience is held to
Handles challenge without either caving or digging in
Works across legal, operations, and external counterparties
Five-point scoring guide
1
Poor
Cannot communicate beyond technical peers.
2
Needs Improvement
Explanations lose the audience or oversimplify to the point of error.
3
Satisfactory
Adequate with familiar audiences; less effective under challenge.
4
Very Good
Explains clearly to committees and regulators and holds up under challenge.
5
Excellent
Translates category level emissions into ranked abatement options with cost implications, and has changed a leadership decision with that analysis.
