Your sustainability team is stretched. We become the team behind them.
One person can’t be responsible for everything. Scope 1, 2 and 3 carbon accounting. ESOS compliance. Net-zero strategy. Supply chain assessments. Thallo can become the team behind them – at a fixed monthly cost.
Companies already working with Thallo
ESOS, SECR, Scope 1, 2 and 3 reporting, net zero, supply chain due diligence. Five frameworks. Five deadlines. Most sustainability teams have 1-3 people covering all of it. The scope grows every year. The headcount doesn’t.
Responsible for everything. Resourced for a fraction of it.
Carbon accounting, regulatory compliance, net-zero strategy, board reporting, supply chain assessments. The remit keeps expanding. The team doesn’t.
are not adequately resourced
Scope 1, 2 and 3 carbon accounting, ESOS, SECR, net-zero targets. The remit keeps growing. The team and budget don’t.
stretched beyond their expertise
Compliance, carbon accounting, strategy, reporting, supply chain. No single person has deep expertise across all of it. Industry research now recommends lean core teams augmented by fractional specialists – this is exactly the model Thallo delivers.
are confident of hitting their targets
Down from 25% in 2024. Confidence is falling because the gap between ambition and capacity keeps widening. A fractional team closes that gap.

You’ve probably already considered these
| Option | Cost | The reality |
|---|---|---|
| Hire a Sustainability Manager | £75-90k/year | 6 months to recruit. 3 months before they’re productive. 9 months before output. Still one person. |
| Traditional consultancy | £1-2k/day | Project-based. They deliver a report, then leave. No continuity. No one owns the follow-through. |
| Specialist auditor only | £5-15k per audit | Covers one thing. Doesn’t do your carbon accounting, write your SECR report, handle Scope 3 data collection, or manage your net-zero roadmap. |
| Keep muddling through | Free (for now) | Regulations are tightening, not easing. ESOS action plans go public this year. Scope 3 reporting is coming. Your board, customers, and competitors will see where you stand. |
| Thallo (fractional team) | From £1,500/mo | Starts in days. Fixed monthly cost. A team, not a person. |

Not sure where the gaps are?
Seven pillars of sustainability support, tailored to your needs
From Scope 1, 2 and 3 carbon accounting through to net-zero strategy, carbon market access, and board reporting. A holistic approach, not just compliance box-ticking.
Compliance and regulatory
ESOS, SECR, and emerging UK SRS requirements. Regulatory monitoring, gap analysis, deadline tracking, and action plan management. We own the timeline so you don’t have to chase it.
Reporting and disclosure
Sustainability reports aligned with GRI, CDP, TCFD/ISSB, and bespoke investor or customer requirements. From data collection through to board-ready, publication-ready output.
Carbon accounting and energy management
Full Scope 1, 2, and 3 carbon accounting. Energy analysis, emissions baselining, reduction targets, and offset strategy – with direct access to high-integrity carbon credits through Thallo’s marketplace.
A net-zero plan the board can actually use
Sustainability strategy, materiality assessments, net-zero pathways, KPI setting, and board-ready narratives. Strategic, not just operational.
Stop dreading customer questionnaires
Supplier assessments, sustainable procurement policies, customer questionnaire support, and Scope 3 data collection across your value chain.
Build internal capability over time
Internal and external sustainability comms, employee engagement, stakeholder updates, and team training. We don’t create dependency – we build your capacity.
