The problem
Most sustainability teams are still working in Excel. That's a problem.
"Our data is all over the place."
Activity data in one spreadsheet, emission factors in another, reports emailed as PDFs. One wrong formula corrupts the whole inventory.
"We can't prove our numbers."
Auditors need a full calculation trail. Spreadsheets provide none, and recreating the methodology during a review takes weeks.
"It takes months every year."
Manual data collection, chasing suppliers for Scope 3, formatting reports. The same work, repeated annually, with no institutional memory.
SusDevOS solves all three — free to start.
How it works
From activity data to verified report in three steps
No configuration. No consultant required. Start entering data on day one.
Enter your activity data
Fuel use, electricity, travel, purchased goods — in the units you already have. Emission factors from DEFRA, EPA and Climatiq apply automatically. No formula required.
Review your calculated inventory
See Scope 1, 2 and 3 totals in real time. Both Scope 2 methods calculated simultaneously. Track restoration sequestration and TNFD metrics. Flag data quality issues before they become audit findings.
Generate and submit your report
One click produces a GHG Protocol-conformant PDF, ready for your verifier, Verra/Gold Standard, or TNFD disclosure. Every emission factor and GWP value is included and documented.
Built for your role
Every workflow, one platform
Whether you're managing one entity or thirty client accounts, SusDevOS adapts to your workflow.
Auto emission factors
DEFRA 2024, EPA eGRID and Climatiq — 10,000+ factors updated annually, applied automatically.
Scope 3 assessment
Guided relevance checklist for all 15 categories. Documented decisions, no guesswork.
Verification workflow
Internal approval → third-party sign-off → immutable verified record.
Audit-ready PDF
Every factor, every GWP value, every boundary decision fully documented.
TNFD LEAP nature reporting
Locate, Evaluate, Assess, Prepare framework for biodiversity impacts — TNFD v1.0 aligned.
Verra/Gold Standard validation
Real-time registry check on offset serial numbers — unvalidated credits never deducted from net totals.
