Managed Services

Your sustainability function, operated for you

Sustainability work is continuous, but few organisations can justify a full in-house team for it. We operate the function as an embedded service — the same people every cycle, working to your calendar.

  • Named team
  • Annual calendar
  • Platform included

Inclusions

What the retainer covers

Scoped to your reporting obligations and scaled as they grow. You get continuity of people, which is what makes year two cheaper than year one.

  • Quarterly carbon inventory updates and annual close
  • Full ownership of the reporting calendar and internal deadlines
  • Supplier data collection and Scope 3 engagement programmes
  • Assurance coordination and verifier query management
  • Platform licence, configuration and ongoing maintenance
  • Quarterly performance reviews against your targets

Model

How the service runs

  • A named team

    The same analysts and reporting lead each cycle, so institutional knowledge accumulates rather than resets.

  • Managed calendar

    We own the timetable, chase the inputs and escalate early when something is at risk of slipping.

  • Supplier engagement

    Ongoing outreach that steadily converts spend-based Scope 3 estimates into supplier-specific data.

  • Platform operations

    Configuration, integrations, factor updates and QA handled as part of the service.

  • Capability transfer

    Documented processes and training, so bringing the function in-house later remains a real option.

  • Executive reporting

    Quarterly briefings written for your board, with progress against target and honest variance analysis.

Questions

Retainer questions

  • How is the retainer priced?

    On the scope of your reporting obligations and the number of entities and sites in the boundary, not on headcount hours. We agree deliverables and a calendar up front so the commercial basis stays predictable.

  • Does this replace our internal team?

    Usually it supports a small internal team rather than replacing one. Most clients keep an internal owner for strategy and stakeholder relationships while we run measurement, reporting and supplier engagement.

  • What happens if we want to exit?

    You keep your data, your platform configuration and the documented processes. We build for capability transfer from the start, and will run a structured handover to your internal team or another provider.
