How we work
Four steps, one set of numbers.
The same team measures, sets the target, stays for the cuts and writes the report. Nothing is handed over a wall.
A footprint your auditor will sign.
We collect a year of energy, fuel, travel and purchasing data and turn it into a Scope 1, 2 and 3 footprint, with every figure traced to its source.
You getBaseline report and data room
A date and a slope you can defend.
We model three pathways against your growth plan and agree one science-based target the board, the bank and your largest customer will all accept.
You getNet zero pathway and board paper
The cuts, in the order that pays.
A costed list of projects ranked by tonnes per pound. We stay on site with your operations team until the first third of the cut is delivered.
You getCosted reduction plan, delivered with you
One set of numbers for everyone who asks.
The annual disclosure, the customer questionnaires and the impact report all come from the same checked dataset, ready for assurance.

In their words
Clients who can show their working.
01 of 05They rebuilt our footprint from the vans up. For the first time the board and the depot managers were looking at the same number.
Other firms gave us a target. Overstory gave us the order to do things in and what each step would cost.
Our first report passed assurance without a single restatement. I did not think that was possible in year one.
They told us not to buy two sites. That advice has already paid for the next ten years of their fees.
The power contract was explained to us in one page. We signed it knowing exactly what we were exposed to.

01of 08Still unsure?Send us your last energy bill and a headcount. We reply with a rough footprint inside two working days.Ask a consultantQuestions
What clients ask before the first call.
- With a baseline call. In 40 minutes we work out which data you already hold, usually energy bills, fuel cards and purchase ledgers, and what a first footprint would take. Most companies have 70 percent of what they need.
- Six to nine weeks for a single-country business, a little longer with many sites. The time goes on collecting data, not on calculating.
- A first footprint starts at £14,000 and a full net zero strategy at £22,000. Every proposal has a fixed price and a list of what you receive.
- We prepare targets to the science-based standard and manage the submission. Sixty-two of our clients hold a validated target today.
- No. About half our clients start without one. We work with finance and operations and leave you with a data model one person can run.
- No. We have no stake in what you buy. If removals belong in your plan we help you specify and tender them.

- We stay for the first year on a light retainer: quarterly reviews against the pathway and help when a lever turns out harder than modelled.
