Procurement, on-site generation and the arithmetic behind a date. We read the contracts you already hold line by line — tariffs, certificates, power purchase agreements — and say plainly which of them change the emissions figure and which only change the paperwork. A certificate bought after the fact is not the same claim as a contract that brought new capacity onto the grid, and the plan says which you have.
On-site options are costed against the same yardstick: what they actually displace, metered at the site rather than apportioned from a group total. The result is a supply plan you can put in front of a finance director and an assurer on the same afternoon.
Which sites count, and which contracts count for them. A group-level average will always look tidier than eleven sites metered one at a time, and it will always hide the sites moving the wrong way. We meter site by site, read each one monthly, and keep the ones that got worse in the same table as the ones that improved.
Eleven sites, metered one at a time. A group average would have hidden the two that moved the wrong way, and those were the two worth knowing about.
Eight to twelve weeks from the first data pull you receive the supply plan, the costed on-site options and a net-zero date with every step of its arithmetic attached.
The date is the least interesting part of it. What survives scrutiny a year later is the working underneath, and that is handed over in a form you can re-run yourself.
What you receive
Every figure arrives like this one: the factor it used, where that factor came from, and whether the number was measured or modelled.
Metered
Read off a meter, not estimated.
Factor
The published source, with its date.
Uncertainty
How far the figure could move.

Page counts are from the last engagement of this size. If a figure in any of them cannot be traced back to the line it came from, it does not leave the building.
