NHS Net Zero roadmap · April 2027 milestone · 41 weeks

Staff-travel carbon, measured — not estimated.

Ozomark turns real staff journeys into audit-ready NHS Scope 3 carbon — every leg classified on the employee's phone, so the raw GPS never leaves it.

The roadmap

The NHS clock is already running.

A measured baseline takes a year of real journeys. Start late and you reach the gate empty-handed.

Countdown to 1 April 2027

41 weeks

Until measured Scope 3 travel data is the NHS standard. A baseline can't be backdated.

  1. April 2027

    No Carbon Reduction Plan, no bid.

    Your CRP must cover all of Scope 1, 2 and 3 — staff travel included.

    April 2027: No Carbon Reduction Plan, no bid.

  2. April 2028

    Per-product footprinting begins.

    Your travel data has to already exist — you can't collect a year of it overnight.

    April 2028: Per-product footprinting begins.

  3. Hard gate

    No measured progress, no new NHS contracts.

    This is the gate. Suppliers qualify only on evidenced, year-on-year progress.

    From 2030: No measured progress, no new NHS contracts.

A baseline takes a year of real journeys — so the slow part starts today. Ozomark is built for every milestone: measured now, ready for what's next.

The gap

Surveys guess. Ozomark measures.

Surveys and commute apps rest on self-report. Ozomark measures the real journey on the phone.

How it works

Three steps. No surveys, no mileage forms, no spreadsheets.

Employees download the app, journeys classify themselves on the device, and your CRP — Scope 1, 2 and 3 — generates itself.

  1. Step 01

    Employees download the app

    Share a join link. Staff install the app once and opt in. Setup takes minutes, needs no hardware, and asks nothing of them again.

  2. Step 02

    Journeys auto-classify on the device

    Journeys are captured and classified into transport modes on each phone — raw GPS never leaves the device. No daily prompts, no logging, no forms.

  3. Step 03

    Your CRP generates itself

    Your dashboard shows organisation-wide travel emissions in tCO₂e covering Scope 1, 2 and 3. Export a board-ready Carbon Reduction Plan summary, ready for assurance.

The engine

Open the spine. Meet the engine.

Reconstructed on the device from 20+ motion signals and the UK's transport network — sealed before a coordinate ever leaves.

  1. Evidence-accumulation scoringEvery signal votes — the strongest case wins.
  2. 20+ signals per legSpeed, bearing, altitude, accuracy — all fused.
  3. 12 transport modesWalk to tube, bus to ferry — told apart.
  4. Infrastructure-awareEvery UK stop and rail line, bundled and offline.
  5. Rail-track snappingKnows which line you rode, not just that it was rail.
  6. Underground reconstructionRebuilds the journey where the signal dies.
  7. Cold-start recoveryRecovers the start before tracking woke up.
  8. Complete-timeline guaranteeNo blank spots — every metre accounted for.
