Confronting structural gaps in sustainability data
CSDX turns information from a recurring source of friction into shared infrastructure for accountability, innovation and scale.
Fragmented data quality
Metrics are defined differently across portals and frameworks, while source evidence often remains trapped in PDFs, photos and spreadsheets.
Costly access
Paywalled tools, bespoke integrations and duplicate reporting exclude smaller actors and make the same information expensive to collect repeatedly.
Fragile trust
Missing timestamps, overwritten values and weak links to source evidence make sustainability claims difficult to verify and defend.

Publish once at source
Enterprises, suppliers, utilities and public agencies publish activity records through accessible connectors while retaining control of their data.
Discover and request
Authorized users discover comparable records and request only the information required for a defined purpose.
Exchange with permission
Purpose-bound, time-bound and revocable consent governs how information moves across the network.
Verify and transform
Assurance providers and data services attach attestations, improve quality and generate decision-ready derivatives.
Reuse for real decisions
The same trusted record can support finance, procurement, insurance, regulation, disclosure and innovation.
Infrastructure for precision, trust and scale
Common language
Comparable schemas align ESG, carbon and climate-risk information across tools and frameworks.
Decentralized control
Data remains with its originator while becoming discoverable to authorized stakeholders.
Audit-ready provenance
Digital signatures, timestamps, version histories and source links make reliability explicit.
Open extensibility
Builders can create new finance, risk, compliance and market services on common infrastructure.
Initial use cases
Comparable Scope 3 exchange
Suppliers publish standardized records once so buyers, banks and regulators can build current, comparable emissions views.
Performance-linked finance
Verified sustainability performance can inform loan pricing, project drawdowns and impact reporting.
Export-ready evidence
Signed ESG and emissions packets make trade compliance more routine and credible.
Climate-risk underwriting
Geolocated assets connect to common hazard data for finance, insurance and permitting decisions.
Verified-savings SME upgrades
Trusted energy baselines can support repay-from-savings finance for efficiency and resilience investments.
Join the effort to build trusted climate data infrastructure.
This is an evolving thesis and an invitation to co-create the shared rail.
