POLICY & GOVERNANCE
The Sustainability Framework
Mandatory vs voluntary. Disclosure vs action. And the data infrastructure beneath them all.
Every sustainability standard, regulation, and certification fits somewhere in this structure. Click any chip in the diagram to understand what it is and why it matters.
How the landscape is structured
Two axes organise every framework. Beneath all four quadrants sits the data infrastructure layer — the measurement and provenance evidence that every standard depends on, but that most guides leave out.Click any chip to see what it is.
Report what you find
Disclose voluntarily
Act — legally required
Commit to change voluntarily
What the ecosystem is — measuring state and change at site and landscape scale.
What flows out of the ecosystem — verified origin and provenance up through the supply chain.
Mandatory-transformation quadrant (bottom-left) is where enforcement and legal liability sit. Data foundation layer added by Pandion; original 2×2 concept: Burkart, One Earth, 2025.

The four tiers
The framework ecosystem is layered. Each tier depends on the ones below it. Goals set the targets; governance mandates action; frameworks provide the tools; markets create the financial flows.
International treaties, scientific targets, and the accounting standards that underpin everything else. Paris Agreement, Kunming-Montreal GBF, GHG Protocol, TCFD.
Mandatory disclosure regimes. What large companies must report. CSRD, UK SRS, ISSB, SFDR, EU Taxonomy. Supply chain data demands flow down from these.
Voluntary standards, disclosure platforms, and certifications. CDP, TNFD, SBTi, SBTN, GRI, B Corp. What leading organisations choose to do, and what becomes mandatory next.
Mechanisms that create financial flows from sustainability action. BNG, Woodland Carbon Code, biodiversity credits, and the SME pathway from awareness to disclosure.
Key relationships to understand
The map shows over 40 connections. These six are the ones that matter most for understanding how the ecosystem works in practice.
UK SRS is the container. CDP, SBTi, TNFD, and SBTN fill it.
When a large company files UK SRS, it draws on CDP for climate data, SBTi for its validated target, TNFD for its nature risk assessment, and GHG Protocol for its accounting methodology. UK SRS is the regulatory vehicle; the voluntary frameworks are the methodologies. Understanding this explains why voluntary frameworks matter even to organisations not directly subject to mandatory reporting.
TCFD was voluntary in 2017. It is embedded in mandatory law today.
TCFD's four-pillar structure (Governance, Strategy, Risk, Metrics) now appears verbatim in ISSB S2, CSRD, and UK SRS. TNFD follows the same structure and the same trajectory. The voluntary frameworks of today are the regulatory baselines of tomorrow, which is why early adoption builds capability ahead of compulsion.
CDP and SBTi were designed to reinforce each other: they share co-founders.
CDP co-founded SBTi. CDP's scoring rewards companies with SBTi-validated targets. SBTi requires annual progress reporting, often via CDP. The two frameworks create a recurring engagement cycle. Understanding this relationship helps you sequence work deliberately rather than being led by either.
TNFD and SBTN are designed as a pair: disclosure and targets for nature.
TNFD provides the disclosure framework (what to report about nature dependencies, impacts, and risks). SBTN provides the target-setting methodology (what to commit to for nature). Neither is complete without the other. Together, they do for nature what TCFD and SBTi do for climate.
Carbon credits and biodiversity credits are not greenwashing tools. They are disclosure infrastructure.
Verra, Gold Standard, and the Biodiversity Credit Alliance exist because corporate buyers under CDP, SBTi, and SBTN obligations need verified, third-party evidence that nature and climate action happened. A WCC credit is not a substitute for reducing emissions (SBTi forbids using offsets for target compliance): it is the MRV documentation that proves a landscape is sequestering carbon, which then feeds into a corporate's net zero transition plan and TNFD nature disclosure. The markets tier is where abstract framework commitments become financial flows back to landscapes.
The SME pathway is a designed ecosystem: Awareness, Commitment, Disclosure.
UK Business Climate Hub (government-endorsed awareness), SME Climate Hub (commitment / UN Race to Zero pledge), and CDP SME Questionnaire (annual scored disclosure) were built to connect. The SME Climate Hub was developed in direct collaboration with CDP; the questionnaire is the designed disclosure pathway for Hub signatories. The three stages are not independent: they are a sequenced journey.
Where do I sit in this?
Most organisations are not in all four quadrants simultaneously. Your starting point depends on your size, sector, and who your customers are.
Small farm, estate, or land manager
Mixed farm, sporting estate, rewilding project, market garden
Where you are now
Certifications (Pasture for Life, FSC, RSPCA Assured), carbon and biodiversity credits, and voluntary target-setting. Not yet directly caught by mandatory disclosure.
What is arriving
EUDR if you produce cattle or timber. BNG habitat bank income. Supply chain Scope 3 data requests from buyers caught by CSRD.
Your data foundation
Your soil surveys, water quality records, and habitat mapping are already your most valuable data assets — they unlock carbon credits, BNG income, and supply chain credibility with enterprise buyers.
Food and beverage brand or processor
Dairy, meat, bakery, drinks, ingredients
Where you are now
Large corporate customers are under CSRD and UK SRS — they need your Scope 3 data. CDP and B Corp are increasingly expected for brand credibility. EUDR affects commodity sourcing.
What is arriving
CSDDD supply chain due diligence obligations arriving via enterprise customers before they apply directly. Expect questionnaires from 2026.
Your data foundation
Farm-level traceability and plot-level origin data are what your buyers will demand. Start building supplier data capability now, before it becomes urgent.
Mid-market company approaching the threshold
Manufacturer, retailer, professional services, £50M to £500M revenue
Where you are now
Approaching mandatory reporting thresholds. Supply chain data pressure from CSRD-caught customers arrives before direct regulation does. Voluntary CDP and SBTi now build the capability you will need.
What is arriving
UK SRS mandatory disclosure likely within 3 to 5 years at your scale. CSDDD supply chain obligations from enterprise customers arriving earlier.
Your data foundation
A carbon inventory, a water account, and basic supplier mapping satisfies 70 to 80% of CDP, TNFD, SBTN, and SBTi requirements at the same time.
The data foundation: why it matters
Every claim made in the four quadrants above — every disclosure filed, every certification granted, every credit issued — depends on data that originates below. Most organisations already generate this data. Most do not yet realise its value.
MRV — landscape and horizontal
Measurement, Reporting, and Verification of what the ecosystem is. It operates at landscape scale — measuring the state of soil, water, habitat, and carbon stocks across a site at a given moment in time.
MRV data is site-anchored and third-party verifiable. It answers: what actually changed here, and can we prove it? Without it, carbon credits cannot be issued, BNG units cannot be registered, and TNFD nature assessments have no foundation.
Example: water quality readings from your pond and river, collected over years, are MRV data. They are already there — they just need structuring to unlock their value.
Traceability — value chain and vertical
The verified chain of what flows out of the ecosystem — from field through processor, brand, retailer, and back through circularity. Traceability does not measure what happened at a location; it proves that the product you are buying came from that verified location.
It answers: where did this come from, and can we prove it? EUDR's plot-level traceability requirement is the clearest current example — every batch of cattle or timber must be geo-referenced to its origin before EU market placement.
Example: a chain-of-custody record linking your Pasture for Life certified beef back to your specific fields — that is traceability. It makes your MRV data commercially useful.
The connection: MRV tells you what happened at location X. Traceability proves that the product you bought came from location X. Together they are the credible evidence chain that the disclosure frameworks above require.
The voluntary → mandatory trajectory
The pattern is consistent: voluntary frameworks become mandatory. Organisations that adopt early build the capability before others are forced to catch up.
