Scope 3 emissions management is becoming a growing priority for public sector estates teams as carbon management extends beyond energy use within buildings. Increasingly, attention is turning to indirect emissions generated across supply chains, including contractors, maintenance providers, cleaning services, outsourced operations and supplier reporting. These emissions are under increasing scrutiny as public sector organisations face tighter net zero targets, reporting requirements and stakeholder expectations.
How to Improve Scope 3 Emissions Management
1. Understand the scale of the challenge
For many public sector organisations, Scope 3 emissions represent the largest and least understood portion of their carbon footprint. Facilities management supply chains are often complex, involving multiple vendors delivering services across estates that may span schools, hospitals, offices and community buildings.
Emissions arise from a wide range of activities, including contractor travel, maintenance work, equipment use, cleaning services, the production of cleaning materials and replacement parts. Without clear visibility, these emissions can be difficult to quantify and manage effectively.
2. Improve data and supplier visibility
A key priority for FM and energy managers is improving the quality of emissions data across suppliers. Many organisations now require contractors and service providers to provide standardised carbon reporting aligned with frameworks such as the Greenhouse Gas Protocol.
Digital procurement and contract management systems are increasingly being used to capture and analyse supplier emissions data. This enables estates teams to build a more accurate picture of their Scope 3 impact and identify areas where emissions can be reduced.
However, data quality remains a challenge, particularly for smaller suppliers that may lack the tools, resources or expertise to report emissions consistently.
3. Embed carbon considerations into procurement
Public sector procurement is becoming a powerful lever for improving Scope 3 emissions management. Carbon performance is now being incorporated into tender evaluations, supplier selection and contract KPIs alongside cost and service delivery.
This shift is encouraging suppliers to invest in lower-emission operations, such as:
- Transitioning to electric vehicles
- Reducing travel-related emissions
- Minimising waste
- Adopting more sustainable materials
- Improving supplier reporting processes
Framework agreements and long-term contracts can also support collaborative decarbonisation efforts across facilities management supply chains.
4. Work in partnership with suppliers
Managing Scope 3 emissions requires collaboration. Leading public sector organisations are working more closely with suppliers to set shared targets, provide guidance and build capability.
This may include:
- Offering training on carbon reporting
- Sharing best practice
- Supporting suppliers with data collection
- Co-developing decarbonisation plans for specific services
By working in partnership, estates teams can encourage more consistent reporting and accelerate carbon reduction across outsourced operations.
5. Move from reporting to carbon reduction
As reporting requirements evolve, the focus is shifting from measurement to meaningful reduction. For FM and energy leaders in the public sector, this means moving beyond data collection towards practical interventions that reduce emissions across day-to-day operations.
Examples include reviewing contractor travel, improving maintenance schedules, selecting lower-carbon cleaning products, reducing waste and using procurement decisions to favour suppliers with credible carbon reduction plans.
Making Scope 3 emissions management a strategic priority
In a landscape of increasing accountability, Scope 3 emissions management is becoming central to delivering credible, organisation-wide net zero strategies. By improving supplier reporting, embedding carbon into procurement and working collaboratively with contractors, public sector estates teams can reduce emissions across the entire estate ecosystem and ensure that sustainability commitments translate into measurable action.
