Activity without structure doesn't hold up

?

No single owner

Carbon, EcoVadis, B Corp and policies sit in different corners with no one accountable for the whole picture. Boards can’t answer for what they can’t see.

!

Reporting demands are converging

CSRD, ISSB and investor questionnaires increasingly expect governed, comparable data — not a deck assembled the week before.

It’s now a deal factor

Buyers, lenders and acquirers price ESG risk. A credible governance framework protects valuation and removes friction at diligence.

What a governed ESG function looks like

1

Diagnose

We benchmark your position, map buyer and regulatory demands, and find the growth blockers.

2

Measure

Robust, GHG-Protocol aligned baselines and the data foundations your reporting depends on.

3

Deliver

Plans, ratings and certifications executed to the standard your clients and investors expect.

4

Embed

We build the in-house capability and governance so credibility compounds over time.

One person can’t do it all

As mid-market businesses grow, sustainability demands become more complex & commercially impactful.

Many ambitious teams struggle with:

New Procurement Expectations
Public and private clients demand robust carbon data, Net Zero targets & 3rd party ratings
Growing Reporting Complexity
Emissions data, disclosures and stakeholder reporting scales as your business grows
Alignment With Broader Goals
Teams often lack a roadmap that meets commercial objectives and investor expectations
Limited Internal
Capacity
Most lack full-time sustainability owners or the niche expertise to deliver on broad requirements

Here’s how

we can help

What is fractional sustainability support?

Fractional sustainability support gives you sustainability capability on a flexible, ongoing basis — without committing to a full-time hire.

Even experienced in-house leaders cannot cover every aspect of ESG, from carbon reporting and certifications to supply chain engagement and tender responses. They often still rely on multiple external consultants to fill gaps.

Our model gives you access to a broad, integrated team covering strategy and delivery, through one relationship and one accountable partner.

We embed into your organisation, taking primary responsibility for meeting your sustainability requirements and maintaining credibility with customers, investors and regulators. When the time is right, we can support recruitment and transition capability smoothly in-house.

Meet your sustainability partner

Sustainability performance becomes essential before most businesses are ready to hire for it.

Our fractional model delivers expert capability, commercial protection and long-term strategy, without prematurely increasing headcount.

Why choose Litmus as your fractional sustainability partner

At Litmus, we provide embedded ESG leadership that combines strategic oversight with hands-on delivery. We don’t just advise. We take responsibility for carbon reporting, compliance, ratings and governance, ensuring your sustainability function operates with structure and credibility.

You set the pace. Whether you need rapid support during acquisitions and reporting cycles, or steady long-term capability building, we flex our resource to match your business stage and pressure points.

Our work goes beyond box-ticking. We help clients build investor-grade ESG governance, integrate acquired businesses smoothly, and strengthen buyer confidence, all without prematurely expanding internal headcount.

And crucially, we don’t create dependency. As your sustainability maturity increases, we help define the right in-house role, support recruitment, and guide onboarding. This ensures you build internal capability at the right time, in the right shape.

Do any of these sound familiar?

You are working with larger clients

As your clients mature, they face their own pressure to walk-the-walk. Larger corporates now assess ESG as part of their supply chain, and public sector bids require formal compliance and carbon plans.

Your internal team is already stretched

You don’t have a full-time sustainability lead, or your ESG team lacks the capacity to keep pace. Reporting peaks, audits and tender deadlines create pressure that pulls focus away from core business priorities.

You are preparing for growth or investment

Expansion through organic growth or acquisition increases reporting complexity and stretches existing ESG teams. Without management, sustainability can quickly block future contracts.

Reporting requirements are getting complex

As you grow, reporting requirements accelerate. Carbon footprints, product footprints, SECR, ISO standards, EcoVadis and CSRD are just a few requirements you could be asked for.

You lack a future-proof strategy

You’re implementing sustainability projects, but they aren’t fully aligned with growth plans, future tender strategy or evolving stakeholder demands. Clear roadmapping is key to minimising business risk.

You want long-term credibility

Clients are including reduction targets in contracts, and competitors are becoming suppliers of choice. You want a structured approach that strengthens credibility over time, not reactive fixes.
