Carbon Reduction Plan

Prometheus’s Carbon Reduction Plan 2026

Prometheus has worked with ClimatePartner to calculate our Corporate Carbon Footprint (CCF). The CCF for 2025 reflects the total CO² emissions released by Prometheus, within the ClimatePartner system boundaries, during the reporting period of January 2025 to December 2025.

All calculations were based on the guidelines of the Greenhouse Gas Protocol Corporate
Accounting and Reporting Standard (GHG Protocol).

Prometheus’s commitment to achieving
Net Zero

We are committed to achieving Net Zero ahead of the expectations set by our clients and our wider stakeholder community. We aim to achieve Net Zero by 2045.

Emission Scope Categories

Scope 1: Direct carbon emissions from owned or controlled sources
Scope 2: Indirect carbon emissions from consumed purchased electricity, heat or steam
Scope 3: Indirect carbon emissions from all other business activities

Baseline Emissions Footprint

Baseline emissions are a record of the greenhouse gases that have been produced in the past. Baseline emissions are the reference point against which emissions reduction can be
measured.

Current Emissions Reporting

Largest Emission Sources

Prometheus’s Corporate Carbon Footprint for 2025 is 1,037.28 tCO₂e, with emissions
predominantly in Scope 3 (866.80 tCO₂e; 83.56%), alongside a material contribution from Scope 1 emissions (156.84 tCO₂e; 15.12%) due to the use of company vehicles.
The dominant contributor is employee commuting and working from home (788.48 tCO₂e;
76.01%), reflecting the distributed nature of the workforce and the requirement for staff to travel.
Scope 1 mobile combustion (154.01 tCO₂e; 14.85%) also represents a significant source of
emissions, driven by vehicle use in service delivery.
Other contributors include fuel- and energy-related activities (41.13 tCO₂e; 3.97%), purchased goods and services (24.11 tCO₂e; 2.32%), and business travel (13.07 tCO₂e; 1.26%), each representing a relatively small proportion of total emissions.

Emissions reduction targets

Building on our first fully scoped Corporate Carbon Footprint, our focus is on implementing targeted actions aligned to our primary emission drivers and continuing to improve data quality over time.
We will target a minimum 2% year-on-year reduction in emissions initially, with a focus on
reducing emissions from employee commuting and operational vehicle use.
In support of this, Prometheus will deliver specific environmental targets for FY2027, including reducing single-occupancy commuting, increasing adoption of lower-emission vehicles, and progressing the transition of the operational fleet.

Carbon Reduction Projects

Completed and Ongoing Carbon Reduction Initiatives
The following environmental management measures and projects were implemented prior to the establishment of a fully scoped carbon baseline. While these initiatives are expected to have contributed to reducing emissions, their impact was not formally measured at the time.

• Installed PIR sensors and adjusted fan coil timers at Prometheus HQ (Fort Dunlop)
• Introduced sub-metering at HQ to monitor office-specific consumption
• Established the integration of electric vehicles (E-Vivaro) into the fleet
• Used telematics to track driver behaviour and identify inefficiencies
• Raised awareness and provided behavioural change training for staff driving fleet vehicles

Planned Carbon Reduction Initiatives
In the future, we propose to continue with the live initiatives above and implement further
measures, such as:

1.Employee commuting and workforce travel
We will prioritise reductions in emissions from employee commuting and workforce travel, which represent the majority of Prometheus’s carbon footprint.

• Develop and implement Green Travel plans across the organisation
• Target a reduction in single-occupancy commuting, supported by incentives for car sharing
  and public transport
• Promote active travel where operationally feasible
• Provide travel guidance and awareness campaigns to encourage lower-carbon behaviours

2. Fleet and operational vehicle use
We will reduce emissions from operational vehicle use by improving fleet efficiency and
transitioning to lower-emission vehicles over time.

Deliver a structured fleet decarbonisation programme

• Target 50% of fleet to be electric or hybrid by 2028
• Develop an EV procurement strategy aligned to operational requirements
• Expand use of telematics to improve driver efficiency and reduce fuel consumption
• Continue rollout of electric vehicles where operationally appropriate

3. Office footprint optimisation

Reduce office footprint within the existing Fort Dunlop location to better align with hybrid
working patterns

Optimise space utilisation to support more efficient use of resources and reduce
unnecessary energy consumption, including the use of dedicated bins for recycling

Improve operational efficiency through consolidation of workspace and facilities with sister companies

4. Energy and supporting operational improvements
We will continue to reduce emissions from energy use and operational activities where
feasible.

• Conduct regular energy monitoring and review
• Identify opportunities for energy efficiency improvements
• Explore infrastructure improvements (e.g. EV charging, building upgrades)
• Maintain focus on digital transformation to reduce resource consumption

5. Supporting initiatives

• ESG communications and staff engagement: Strengthen staff awareness and engagement through regular ESG communications, ensuring individuals understand their role in supporting carbon reduction.

• Behavioural change programmes: Encourage lower-carbon behaviours across the
  workforce through targeted initiatives and incentives, particularly in travel and energy use.
• Ongoing emissions monitoring and reporting: Maintain accurate and transparent tracking of emissions to assess progress, inform decision-making, and identify further reduction
  opportunities.
• Employee EV adoption: Support the transition to lower-emission transport by enabling
  employees to adopt electric vehicles, where appropriate, by rolling out an EV salary
  sacrifice scheme (subject to operational and structural readiness).
• A significant proportion of Scope 3 emissions is currently estimated using spend-based data and assumptions. Improving activity-level data capture will be a key focus in future reporting cycles, enabling more accurate reporting and targeted reduction initiatives.
