SUSTAIN CONSULTANCY · FOUNDING STATEMENT
Your supply chain already knows
where it’s failing.
We help it speak.

Four disciplines. One integrated question: what is your supply chain actually doing to the world?
We don’t sell audits. We build the analytical infrastructure that makes your sustainability claims defensible — to regulators, to investors, and to the suppliers you’re asking to change.
The emissions you can't see are the ones that will define your disclosure.
Most manufacturers enter Scope 3 reporting having measured roughly 12% of their actual footprint. The rest — upstream extraction, tier-2 supplier energy, inbound logistics, use-phase emissions — remains invisible. Not because the data doesn't exist, but because no one has built the methodology to surface it.
We construct category-level emission inventories using a combination of spend-based modeling, supplier-collected activity data, and physical intensity factors drawn from LCA databases. The result is a Scope 3 register that holds up to auditor scrutiny and tells you, precisely, where your material hotspots live.
Scope 3 isn't a reporting exercise. It's the first honest map of where your business actually sits in the physical world.
Your suppliers are not a risk category. They are a portfolio of relationships — some of which need redesigning.
Procurement teams are under pressure to produce supplier sustainability scores. The problem is that most scorecards measure disclosure quality, not actual performance. A supplier who fills out an EcoVadis questionnaire comprehensively can outscore one who has genuinely reduced emissions but lacks the bandwidth to document it.
We design scorecards that weight physical performance indicators — verified energy intensity, water withdrawal per unit, labor audit outcomes — against disclosure completeness. The result is a tiered supplier portfolio that tells you who to develop, who to challenge, and who to exit.
A scorecard that measures paperwork is a liability. A scorecard that measures reality is a strategy.
CSRD isn't coming. For many of your clients, it's already here — and it names your supply chain by implication.
The Corporate Sustainability Reporting Directive creates a cascade. Large companies report. Their suppliers — you — become data providers. If you supply into the EU market above certain revenue thresholds, your own value chain data will be requested, audited, and eventually rated.
We work with sustainability officers to build the internal data architecture that makes CSRD compliance a by-product of operational visibility rather than a separate reporting burden. That means data governance frameworks, materiality assessments aligned to ESRS standards, and gap analyses against double materiality requirements.
The companies that treat CSRD as a documentation project will spend twice as much as those who treat it as an infrastructure project.
The circular economy isn't a design trend. It's what happens when the extractive model runs out of cheap inputs.
Virgin material costs are structurally rising. Landfill gate fees are climbing. Extended producer responsibility legislation is expanding. The economics of circularity — which looked marginal five years ago — are now positive in more categories than most procurement directors realize.
We build circularity roadmaps that start with material flow analysis: where does mass enter your system, where does it leave, and at what value? From that baseline, we identify the highest-ROI circular interventions — whether that's closed-loop packaging take-back, post-industrial recycled content substitution, or product-as-a-service models that change ownership economics entirely.
Every kilogram of virgin material you use is a bet that extraction will remain cheaper than recovery. That bet is getting harder to win.
