Commitment Statement
Thornacre Engineering Ltd is committed to achieving Net Zero emissions by 2029.
Baseline & Current Footprint
Thornacre Engineering Ltd is a fully remote software engineering company with no owned or leased office premises. All staff work from home. The company has no company vehicles, gas boilers, or other Scope 1 sources, and purchases no premises-based electricity (Scope 2).
Headcount: 4 full-time, 5 part-time staff (6.5 FTE, calculated at 0.5 FTE per part-time role).
Table 1: Baseline Year (2024)
| Emission Category | Scope Details | Emissions (tCO2e) |
|---|---|---|
| Scope 1 | Direct emissions (no owned vehicles or boilers) | 0.00 |
| Scope 2 | Purchased electricity/heating (no premises) | 0.00 |
| Scope 3: Cat 4 | Upstream transport and distribution (equipment/hardware delivery) | 0.03 |
| Scope 3: Cat 5 | Waste generated in operations | 0.02 |
| Scope 3: Cat 6 | Business travel (rail and personal car; no flights) | 0.90 |
| Scope 3: Cat 7 | Employee commuting and homeworking energy (fully remote; no commuting) | 2.50 |
| Scope 3: Cat 9 | Downstream transport and distribution (no physical goods sold) | 0.00 |
| Total Emissions | 3.45 |

| Scope 2 | Purchased electricity/heating (no premises) | 0.00 |
| Scope 3: Cat 4 | Upstream transport and distribution | 0.02 |
| Scope 3: Cat 5 | Waste generated in operations | 0.02 |
| Scope 3: Cat 6 | Business travel (rail and personal car; no flights) | 0.78 |
| Scope 3: Cat 7 | Employee commuting and homeworking energy | 2.28 |
| Scope 3: Cat 9 | Downstream transport and distribution | 0.00 |
| Total Emissions | 3.10 |
Methodology notes (replace with your actual data before submission):
- Business travel: 3,000 miles/year personal car at ~0.170 kgCO2e/km, plus 4 rail trips/year at ~0.035 kgCO2e/km (assumed 200-mile average return journey). No flights.
- Homeworking energy: calculated using a DESNZ homeworking factor per FTE working hour, applied across 6.5 FTE.
- Cat 4 and Cat 5 figures are low-materiality placeholder estimates for a remote software business with minimal physical procurement and waste.
- All factors taken from the UK Government GHG Conversion Factors dataset. Confirm the exact 2024/2025 factors before publishing, as DESNZ updates these annually.
Emission Reduction Targets
Projected pathway to Net Zero by 2029, baselined against 2024:
| Year | Total Emissions (tCO2e) | % Reduction vs Baseline |
|---|---|---|
| 2024 (Baseline) | 3.45 | 0% |
| 2025 (Current) | 3.10 | 10% |
| 2026 (Target) | 2.60 | 25% |
| 2027 (Target) | 1.90 | 45% |
| 2028 (Target) | 1.00 | 71% |
| 2029 (Target) | 0.00 (Net Zero) | 100% |
Emissions pathway (tCO2e)
2024 |████████████████████████████████████ 3.45
2025 |██████████████████████████████████ 3.10

Residual emissions in 2028-2029 will be addressed through verified carbon offsetting where reduction has reached practical limits, in line with PPN 06/21 guidance on offsetting as a last resort.
Carbon Reduction Projects
Implemented:
- Fully remote operating model since inception, eliminating commuting emissions entirely.
- No company vehicles or leased premises, removing Scope 1 and Scope 2 emissions at source.
- Default to rail over car travel for business journeys where practical.
- No air travel policy for business trips.
Planned:
- 2026: Move to a renewable energy supplier requirement for any staff claiming home working energy reimbursement, and request green tariff confirmation from staff.
- 2026: Introduce a low-emission/electric vehicle preference for any business mileage claims.
- 2027: Engage a cloud hosting provider with verified renewable energy commitments for development and production infrastructure.
- 2027: Implement device refurbishment/longer hardware refresh cycles to reduce Cat 4 procurement emissions.
- 2028: Review remaining residual emissions and source verified carbon offset credits (e.g. Gold Standard or Verified Carbon Standard) to reach Net Zero by 2029.
Declaration and Sign-Off
This Carbon Reduction Plan has been completed in accordance with PPN 06/21 / WPPN 006 and associated guidance and reporting standard for Carbon Reduction Plans. Emissions have been reported and recorded in accordance with the published reporting standard for Carbon Reduction Plans and the GHG Reporting Protocol corporate standard, and the required reporting baseline year, current emissions reported above, are consistent with these guidelines.
This plan has been reviewed and signed off by the board.
