How it works

How the Symphonic Emissions Estimator works

The Symphonic Emissions Estimator walks your team through a defined decision flow. It is country-aware, transparent about assumptions, and honest about confidence — designed for early-stage visibility and ESG readiness, not formal carbon accounting.

01
Mode selection

Choose a Quick Estimate (proxy-based) or Guided Estimate (activity-based) — without mixing the two.

02
Organisation profile

Capture country, industry, employees, revenue band, EU exposure and operations context.

03
Scope relevance

Indicative Scope 1, 2 and 3 relevance based on country, industry and operations.

04
Activity data intake

Quick proxy questions or detailed Scope 1 / 2 / 3 activity inputs.

05
Scope 2 methodology

Apply Location-Based and, where contractual data exists, Market-Based separately — never blended.

06
Factor-source selection

Country and category-aware: NGA, NZ MFE, BEIS/DEFRA, US EPA, CAEP, Canada GHG, with EXIOBASE / GLEC / IPCC fallbacks.

07
Assumptions and proxies

Transparent proxy logic where data is missing — provided vs assumed data is always separated.

08
Indicative calculation

Activity × emission factor, with sensible rounding. No false precision.

09
Confidence rating

Higher / Moderate / Lower confidence by scope and category.

10
Reporting status (AU only)

Indicative AASB S2 Group 1 / 2 / 3 framing for Australian entities only.

11
Executive summary report

A polished report with assumptions, gaps, factor sources, scope breakdown and next steps.

Important: This tool provides indicative emissions estimates only. It does not provide audit-grade calculations, legal advice, formal compliance advice, assurance-ready reporting, or certified carbon accounting outputs. Formal reporting should be validated using current official emissions factors and professional advice.
