Sustainability Officer As A Service
Sustainability officer as a service: embedded expertise without hiring in-house
An embedded sustainability consultant serving as your Visiting Sustainability Officer on a retainer: on site regularly, coordinating between departments, and answering the auditor so your people do not have to.

The sustainability consultant role, as a retainer
Sustainability Officer 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 governance and data 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.
What an embedded sustainability consultant 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
- Tracking key sustainability metrics requires data scattered across departments, with nobody 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 due to fragmented ESG governance
- Real work is being done on the ground, but it is not documented
- Momentum from the last assessment evaporates, leaving your roadmap and net zero strategy stalled

Our role: how the sustainability officer as a service engagement runs
The Visiting Sustainability Officer (VSO) operates as an embedded execution and coordination function across your organization.
| 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 tied to your sustainability metrics, so any document an auditor requests can be produced immediately. |
| Leadership reporting | Structured monthly reporting on ESG governance, progress, risks, and leadership decisions. |
| Execution support | Hands-on delivery of core initiatives, from audit readiness to your net zero strategy. |
Our ESG platform, managed by your sustainability consultant
A sustainability officer as a service engagement includes our full software stack. Your Visiting Sustainability Officer operates it directly, giving you complete visibility without an implementation project.
| Platform | What the VSO does with it |
|---|---|
| Pulse | Runs assessment and ESG data collection across departments, tracks essential sustainability metrics, and validates submissions before recording. |
| Karbon | Maintains carbon accounting month by month to track emissions progress and support your net zero strategy, so annual figures are assembled continuously. |
| Bridge | Manages supplier and vendor data collection, including the follow-up your procurement team would otherwise absorb. |
| Lenz | Keeps your leadership dashboard current for clear ESG governance, ensuring performance against targets is always visible. |

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 sustainability consultant and 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.
FAQ
Frequently asked questions
Something we have not covered? Ask us directly. A straight answer costs nothing.
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. We work alongside your internal lead as an embedded sustainability consultant, they set direction; we make sure it happens
Which sectors do you provide sustainability officer as a service 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.
