Emissions reporting,evidenced end to end.
Collect supplier and facility data, calculate Scope 1-3 emissions, model gaps, and preserve the audit trail behind every number. Hydrus turns sustainability reporting into governed evidence instead of a spreadsheet chase.
Hydrus content is educational and workflow-oriented. Reporting obligations and assurance requirements should be confirmed with qualified advisors.
Sustainability analysis
Scope data, lineage, and reporting readiness.
Collect, calculate, report - with the lineage to back it.
Manual sustainability reporting breaks when source data, assumptions, factors, and approvals live in separate files. Hydrus keeps the number and its evidence together.
Collect from everywhere
Bring in supplier responses, invoices, utility bills, procurement records, travel data, spreadsheets, emails, APIs, and OCR-extracted documents.
Calculate Scope 1-3
Apply activity data, emission factors, market-based and location-based Scope 2 logic, and Scope 3 methods with the calculation context attached.
Report and assure
Create reporting views for CSRD, ISSB, GHG Protocol, CDP, and California climate disclosure workflows from governed source data.
The problem is not the chart. It is proving the number.
Sustainability teams are asked to explain where a number came from, which factor was used, why a method changed, who reviewed the estimate, and whether the source data can be trusted. Hydrus keeps that context available throughout the reporting cycle.
Sustainability analysis
Scope data, lineage, and reporting readiness.
Every calculation needs a source, a method, and a reviewer.
Hydrus structures the operational evidence sustainability teams need before reports are reviewed by finance, leadership, auditors, or assurance providers.
- Supplier questionnaires and supporting evidence
- ERP, procurement, travel, HR, and utility-system activity data
- Invoices, bills, PDFs, and spreadsheets processed through upload or OCR
- Emission-factor source, method, assumption, reviewer, and lineage records
Built for sustainability reporting teams who need defensible evidence.
Scope 1 and Scope 2 calculations
Track direct emissions and purchased-energy emissions with source records and factor selection preserved.
Scope 3 methodology and gap modeling
Use spend-based, average-data, supplier-specific, and hybrid methods while recording when estimates fill missing primary data.
Market-based and location-based Scope 2
Keep the calculation method visible so teams can explain how totals were produced and reviewed.
Supplier data collection
Route requests, collect evidence, flag gaps, and keep supplier responses tied to reportable categories.
Audit trail and data lineage
Preserve source, method, factor, assumption, approval, and change history behind each reportable number.
Multi-framework reporting
Prepare evidence and reporting views for CSRD, ESRS, ISSB, GHG Protocol, CDP, GRI, and California climate disclosure programs.
Keep the reporting requirement connected to the work.
Hydrus links reporting workflows to practical guides and definitions, so teams can understand the requirement, collect the evidence, and explain how each number was produced.
Designed for the data reality of sustainability teams.
Messy source data becomes structured evidence
Lineage connects report totals to source records
Trends and gaps stay tied to calculation context
Governing AI systems too?
The same evidence engine inventories models and agents, routes FRIAs, maps controls, and keeps EU AI Act, NIST AI RMF, and ISO/IEC 42001 evidence connected.
Bring your emissions reporting onto one evidence engine.
