STS Aviation Services Ltd | United Kingdom
Carbon Reduction Plan
Our approach to measuring, managing and reducing greenhouse gas emissions across the UK operations of STS Aviation Services Ltd.
1. Commitment to achieving Net Zero
STS Aviation Services Ltd is committed to achieving net zero greenhouse gas emissions from its UK operations before 2040 .
This Carbon Reduction Plan applies only to the UK operations of STS Aviation Services Ltd. It does not represent the emissions, targets or commitments of the wider STS Aviation Group or any other group company.
We will continue to measure, manage and reduce emissions associated with our UK facilities, transport, workforce, procurement and supply chain. This Plan will be reviewed at least annually and updated to reflect progress, improved emissions data and changes to the UK business.
2. Baseline emissions footprint
Baseline year: 2024
The 2024 baseline emissions figures were taken from the statutory Streamlined Energy and Carbon Reporting disclosure for STS Aviation Services Ltd’s UK operations.
The calculations used:
- the 2019 HM Government Environmental Reporting Guidelines;
- the GHG Protocol Corporate Standard; and
- the applicable 2024 UK Government greenhouse gas conversion factors.
Additional details relating to the baseline calculation
The 2024 baseline includes reported Scope 1 and Scope 2 emissions. Scope 3 emissions were not separately reported for the 2024 baseline period.
The first complete Scope 3 assessment undertaken for the relevant reporting boundary will be used to establish a Scope 3 baseline. The assessment will be developed using the applicable GHG Protocol methodology and the reporting requirements relevant to Carbon Reduction Plans under PPN 006.
The Scope 1 and Scope 2 figures below are presented as rounded figures. The total reported emissions figure of 1,453 tCO₂e is retained from the underlying statutory disclosure.
Baseline year emissions
| Emissions source | Total tCO₂e |
|---|---|
| Scope 1 | 848 |
| Scope 2 | 606 |
| Scope 3 | Not separately reported |
| Total reported emissions | 1,453 |
3. Current emissions reporting
Reporting year: 2025
| Emissions source | Total tCO₂e |
|---|---|
| Scope 1 | 581 |
| Scope 2 | 490 |
| Scope 3 | Not separately reported |
| Total reported emissions | 1,071 |
Reported emissions reduced from 1,453 tCO₂e in 2024 to 1,071 tCO₂e in 2025.
This represents a reported reduction of 382 tCO₂e, or approximately 26.3% against the 2024 reported baseline.
Reported emissions and indicative 2030 projection
Figures below are taken from the supplied draft. Actual figures cover reported Scope 1 and Scope 2 emissions only. Scope 3 has not been separately reported.
The 2030 figure is a draft projection, not a measured result or independently verified forecast. The before-2040 net-zero objective is a proposed commitment requiring management confirmation.
4. Emissions reduction targets
STS Aviation Services Ltd has adopted the following emissions-reduction targets for its UK operations:
- Complete an initial Scope 3 emissions assessment using a documented and appropriate methodology.
- Establish a Scope 3 baseline using the first complete reporting period for which reliable data is available.
- Continue to reduce Scope 1 and Scope 2 emissions through energy-efficiency measures, lower-carbon transport options and improved facilities management.
- Reduce reported emissions to approximately 907 tCO₂e by 2030, subject to improved emissions data and the effectiveness of planned initiatives.
- Achieve net zero greenhouse gas emissions from UK operations before 2040.
- Review progress against these targets at least annually.
The projection of approximately 907 tCO₂e by 2030 represents an indicative reduction of approximately 37.5% against the 2024 reported baseline.
The 2030 projection is based on the reduction in reported emissions between 2024 and 2025 and assumes a gradual reduction pathway towards the company’s objective of achieving net zero before 2040.
5. Completed carbon-reduction initiatives
The following environmental management measures and projects have been completed or implemented within the UK operations covered by this Plan:
- LED lighting has been installed at nearly all company locations.
- PIR sensors have been installed in toilets and offices to reduce unnecessary energy consumption.
- An employee Octopus EV salary-sacrifice scheme has been introduced.
- A Cycle2Work scheme is available to encourage lower-carbon commuting.
- Waste is segregated to support recycling, reuse and recovery and to help prevent avoidable waste from being sent to landfill.
- At the Birmingham Airport site, electricity is purchased through Birmingham Airport, which has installed a major solar-panel installation.
- STS Engine Services has achieved Green Business Certification.
Project-specific emissions savings have not been separately quantified. The 2024–2025 reduction has therefore not been allocated between the individual initiatives listed above.
6. Future carbon-reduction initiatives
STS Aviation Services Ltd intends to investigate and implement further measures for its UK operations, subject to operational, technical and commercial feasibility, including:
- Investigating the introduction of electric vans.
- Reviewing the installation of solar panels at UK company facilities.
- Considering electric-vehicle charging points in UK company car parks.
- Continuing energy-efficiency measures, including LED lighting and PIR sensors.
- Increasing participation in Cycle2Work and EV salary-sacrifice schemes.
- Improving waste segregation, recycling and recovery rates to reduce waste sent to landfill.
- Improving the quality and coverage of Scope 3 emissions data.
7. Emissions calculation methodology
Current reported emissions are based on statutory SECR reporting for STS Aviation Services Ltd’s UK operations.
Future Carbon Reduction Plan reporting will seek to:
- maintain Scope 1 and Scope 2 emissions records;
- identify and assess relevant Scope 3 categories;
- use activity-based or spend-based data where appropriate;
- document assumptions and data limitations;
- apply relevant UK Government conversion factors;
- use the GHG Protocol Corporate Standard and relevant Scope 3 guidance; and
- review data quality and completeness annually.
Where reliable primary data is not available, reasonable estimates may be used and will be clearly identified in the relevant annual update.
8. Governance and sign-off
Responsibility for this Carbon Reduction Plan rests with Simon Morton — Managing Director UK.
Progress will be reviewed:
- at least annually by senior management;
- following material organisational or operational changes;
- when improved emissions data becomes available; and
- where required to support public-sector contract delivery.
Following approval, the final plan will be published at a stable URL and linked prominently from the company website homepage.
Management declaration and sign-off
Status: Awaiting confirmation. This draft identifies Simon Morton, Managing Director UK, as the proposed approver. Formal approval by the appropriate board or equivalent management body, the approval date and sign-off have not yet been confirmed for publication.
Once approval is evidenced, this section must be replaced with the final declaration, name, job title and actual approval date in accordance with the applicable reporting standard.
