The sustainability manager role, as a retainer
Sustainability Office as a Service places a Visiting Sustainability Officer — a VSO — inside your organisation on an ongoing basis. They are on site regularly through the month, coordinating with your departments, maintaining your ESG data and evidence, handling auditor queries, and reporting to your leadership.
Functionally, it is the sustainability manager role. Commercially, it is a retainer — where you get a team’s range of capability behind one relationship instead of one person’s skill set.
Book a consultationWhat it solves
ESG work does not finish when the report is published. Most organisations discover this about six months later, when the next request arrives and there is nobody whose job it is to answer it.
None of these are capability problems. They are ownership problems, and they do not resolve on their own.
- ESG requests arrive from auditors, customers and regulators, with no next steps
- The information needed sits across multiple departments, and nobody has the authority or time to pull it together
- There is one person nominally responsible for sustainability, but they are not trained for it
- Audit season becomes a data hunt, every single time
- Real work is being done on the ground, but it is not documented
- Momentum from the last assessment has quietly evaporated, and the roadmap sits untouched
Our role, and how the engagement runs
The VSO operates as an embedded execution and coordination function.
| Element | What it means in practice |
|---|---|
| On-site presence | Regular scheduled visits each month (frequency varies by engagement). |
| Off-site continuity | Continuous coordination between visits. |
| Auditor liaison | Auditor questions come to the VSO and are closed by the VSO, rather than being distributed across your organisation. |
| Evidence management | A maintained evidence index, so any document any auditor asks for can be produced without a search. |
| Leadership reporting | Structured monthly reporting on progress, risks and decisions needed. |
| Execution support | Hands-on delivery of whatever the current sustainability priority is. |
The platform, operated for you
A VSO engagement includes our full software stack. The VSO operates it, so you get the benefit without the implementation project.
| Platform | What the VSO does with it |
|---|---|
| Pulse | Runs assessment and ESG data collection across your departments, chases follow-ups, and validates submissions before they are recorded. |
| Karbon | Maintains carbon accounting month by month as bills and activity data arrive, so the annual figure is assembled rather than reconstructed. |
| Bridge | Manages supplier and vendor data collection, including the follow-up your procurement team would otherwise absorb. |
| Lenz | Keeps your leadership dashboard current, so performance against targets is visible without anyone being asked for a status update. |

- ESG data collected, validated and recorded on time

Case study — Healthcare
Multi-facility private hospital group, Kerala
The organisation
A multi-facility private hospital group in Kerala, with ESG obligations arising from investor requirements as well as accreditation and statutory compliance.
The problem
ESG audits required inputs from clinical, engineering, housekeeping, HR and procurement functions simultaneously. Without a coordination layer, assembling this was diverting senior administrative attention away from patient care, and it recurred every cycle.
What we do
We are engaged as their Visiting Sustainability Officer on an ongoing basis: coordinating ESG data collection across departments, maintaining the evidence index, handling audit and assurance queries directly, and reporting to leadership. This followed a full engagement cycle — as-is assessment, materiality assessment, ESG strategic framework and sustainability report.
Why the model fits healthcare
Hospitals run continuously and clinical staff have no spare capacity for administrative exercises. The VSO model works here precisely because it takes the coordination burden off people whose time should be spent elsewhere.
Frequently asked questions
Are we handing over responsibility for our ESG performance?
No, and you should not want to. Ownership and accountability stay with your leadership. We provide the execution capacity to act on them.
How long is the commitment?
Engagements typically run annually, because ESG work follows an annual reporting and audit cycle. Shorter arrangements are possible where there is a specific audit to get through.
Do you work with our existing sustainability officer?
Yes, and that is the most effective version of this. They set direction; we make sure it happens.
Which sectors do you do this for?
We are currently strongest in healthcare, manufacturing and technology. The model works anywhere the ESG obligation is continuous and the internal capacity is not.
What if we want to bring it in-house later?
That is a good outcome and we build for it. The systems, documentation and trained departmental contacts stay with you.
