GreenMetrics - About Us

Our approach

We focus on financial materiality.

Where carbon exposure affects real business decisions, we support those decisions with proportionate, defensible analysis.

Where it does not, we advise clients to wait deliberately, with confidence.

Carbon is treated as an input to:

cost management
investment decisions
financing and insurance discussions
customer and market access

Not as a separate initiative.

The Team

Warwick Russell

Founder

Chartered Accountant and CFO

Warwick advises owner-led and mid-market businesses across New Zealand and Australia.

GreenMetrics was established after repeatedly seeing carbon exposure influence:

investment outcomes
operating costs
commercial risk

while being treated as something else entirely.

Lyall Watson

Sustainability CFO

Chartered Accountant and CFO

Leads ISO-aligned carbon measurement and reporting for GreenMetrics clients. Ensures work remains technically robust, proportionate, and decision-ready.

Independence

GreenMetrics operates independently.

Advice is provided without financial interest in financing, technology platforms, or implementation outcomes.

This ensures recommendations remain aligned to the client's commercial interests — not product or funding pathways.

Frequently asked questions

Do we need to do anything on sustainability right now?

For some businesses, acting now reduces risk, protects margin, or preserves options. For others, the right answer is to wait deliberately and with confidence.

The risk is not the delay itself.

It is a delay without understanding whether it is financially neutral or quietly costly.

Is this just ESG, or is it compliance in another form?

No.

We do not start with ESG frameworks, reporting templates, or certification pathways.

We start with commercial exposure:

where costs are already moving
where customers, banks, or insurers are starting to ask questions
where capital, asset, or operating decisions may be affected

If compliance or reporting becomes necessary, it is treated as an input to decisions — not the objective.

Do we need carbon accounting before we can make decisions?

Often, no.

Carbon accounting is useful when a decision depends on it — for example:

a bank or insurer requests
a customer or export requirement
a capital investment comparison
a board-level risk discussion

Starting with full carbon accounting too early often leads to unnecessary cost, rework, or numbers that do not stand up later.

What is the first piece of work you usually do?

A Carbon & ROI Decision Review.

This is a short, CFO-grade decision brief that clarifies:

where carbon exposure is financially material
what matters now versus later
what can be deferred safely
where early action changes the financial outcome

It is not a maturity assessment, scorecard, or net-zero plan.

What if the conclusion is “do nothing for now”?

That can be a sound outcome.

In many cases, the most valuable result is confidence that:

no immediate action is required, and
the business is not quietly accumulating risk

Knowing when not to act preserves management focus, capital, and optionality.
