THE DASHBOARD

One screen for the number your CFO has to put in writing.

Live footprint, scope decomposition, source-level drill-down, and an audit trail that maps every tonne to an invoice, meter, or activity record. Built for sign-off, not slideware.

  • Every figure links to source documents and the emission factor used.
  • Restate prior periods without losing the audit pointer.
  • Export to CSRD ESRS E1, CDP, GRI 305, or SEC climate rule.

PLATFORM

A finance-grade ledger for emissions.

Three things every disclosure team needs and most platforms hand-wave. We don't.

Auditable from invoice to tonne

Every kg of CO₂e back-traces to a primary record — receipt, meter, ERP line, fuel slip — with the emission factor, source, and revision date stamped on it.

  • Versioned factor library (DEFRA, EPA, IEA, ecoinvent)
  • Restate prior periods without breaking lineage
  • SOC 2 Type II · ISO 27001 · GDPR-compliant

Scope 3 that doesn't lie

Hybrid spend-based + activity-based engine for all 15 categories. Average 84% activity coverage on year one — sector benchmark is 38%.

  • Supplier data outreach with response tracking
  • Cat. 1 (purchased goods) by SKU when available
  • Cat. 11 use-phase modeling for product companies

Reports that match the rule, not "best effort"

CSRD ESRS E1, SEC climate, CDP A-list scoring, GRI 305, TCFD pillars — exported in the file format your filer expects, with footnotes intact.

  • iXBRL output for SEC + CSRD digital tagging
  • Side-by-side double-materiality matrix
  • Co-signed by Bureau Veritas in our managed plan
HOW WE CALCULATE

A four-step pipeline. No black box.

Every footprint passes through the same calculation chain. The exact factors and boundary decisions are documented in your workspace and downloadable as a methodology PDF for your auditor.

    Ingest primary data

    Direct integrations with NetSuite, SAP, Workday, Concur, Ramp, AWS, GCP, Azure, and 84 utility APIs. CSVs and supplier portals fill the gaps.

  2. 02

    Apply emission factors

    Each activity record is matched to a region- and year-appropriate factor with full provenance. Factor changes trigger automatic restatement proposals.

    e.g. 412.4 kWh · grid-mix VA 2025 · 0.276 kgCO₂e/kWh → 113.8 kgCO₂e
  3. 03

    Assign scope & category

    Operational vs. financial control. Scope 1/2/3 boundaries follow GHG Protocol; scope 3 categories assigned per CDP guidance with explicit exclusion rationale where data is unavailable.

  4. 04

    Audit & sign-off

    A Tideline assurance lead and Bureau Veritas review your boundary, factor selection, and disclosure draft. Limited assurance opinion issued within 14 business days.

CUSTOMER · LINNEA

Linnea filed their first CDP disclosure in 6 weeks.

A 1,400-person Series-C SaaS company with no prior carbon program. Tideline ingested 18 months of spend, billing, and travel data, modeled scope 3, and produced an assured FY24 footprint in time for their first CDP cycle.

CDP, first cycle
We had a board commitment to disclose by Q4 and no idea how to get a defensible number. Tideline imported the GL, walked us through the boundary calls, and stood up a footprint our auditor accepted on the first review.
The thing I didn't expect: every figure in the report links to the invoice it came from. When CDP asked us to defend our scope-3-cat-1 number, I just clicked through. That's never happened to me with an ESG vendor before.

FREQUENTLY ASKED

Questions a sustainability lead has actually asked us.

What's your scope 3 estimation methodology — spend-based, activity-based, or hybrid?

Hybrid by default. We start spend-based using EEIO factors mapped to your GL, then progressively replace with activity-based data as supplier responses land. Customers reach 84% activity coverage on average within 14 months — versus sector benchmark of 38%. Every line is tagged so your auditor can see the data-quality tier at a glance.

Are you audited by Bureau Veritas or DNV?

Bureau Veritas is our managed-assurance partner — they perform ISAE 3410 limited assurance on customer footprints on our Pro and Enterprise plans. DNV and SGS are supported via a bring-your-own-auditor flow with full read-only access to lineage. We've never had a footprint fail review.

Do you support CSRD reporting for our EU subsidiaries?

Yes — ESRS E1 climate is mapped natively, including the eight required disclosures. We produce both the narrative report and the iXBRL digital filing. Double-materiality matrix is built into the workspace; you can pre-populate it from peer disclosures we maintain in our public-company library.

How do you handle insetting vs. offsetting in the ledger?

They are tracked separately from your gross footprint, never deducted from scope figures. Insets (in-value-chain reductions) are flagged against the relevant scope 3 category with supplier evidence; offsets are tracked on a parallel ledger with vintage, registry, and project type. Reports show gross + net columns side by side, never collapsed.

What's your data ingestion model — do I need to upload spreadsheets monthly?

No. Native connectors to NetSuite, SAP S/4, Workday, Concur, Ramp, AWS, GCP, Azure, and 84 utility APIs pull continuously. Spreadsheets only show up for niche categories — typically two or three per year — and our team handles the templating. Most Pro customers spend under 3 hours/month in the product.
