Climate Risk and TCFD and ISSB S2 Aligned DisclosurePillar 4, Metrics & Targets

Scope 1, Scope 2 and Scope 3 Greenhouse Gas Emissions

We help you disclose your Scope 1, Scope 2 and, where appropriate, Scope 3 GHG emissions and the related risks

Strategic context

What this element is and why it matters

TCFD Metrics and Targets Disclosure (b) asks your organisation to disclose its Scope 1, Scope 2 and, where appropriate, Scope 3 greenhouse gas emissions following the GHG Protocol Corporate Standard. The 2021 TCFD update strengthened the expectations around Scope 3 disclosure, and our team helps you build an inventory that meets them.

Scope 1, Scope 2 and Scope 3 Greenhouse Gas Emissions

Individual significance for organisations

Disclosure MT b is the most closely watched of all the TCFD metrics. Your ESG ratings, investor decisions, the ESG sourcing requirements coming from your customers and your SBTi validation all rest on the quality of your GHG inventory.

Contribution to Climate Risk and TCFD and ISSB S2 Aligned Disclosure

Disclosure MT b is the foundation for the MT c targets and for your SBTi validation. It also feeds your CDP Climate Change, CSRD ESRS E1, SEBI BRSR and SEC climate rule disclosures.

Key requirements

What compliant execution looks like

Scope 1 covering your direct emissions
Scope 2 covering indirect energy emissions on both a location based and a market based view
Scope 3 covering value chain emissions across the fifteen categories
External assurance per ISAE 3410 and ISO 14064 3
Financed emissions per PCAF for financial sector portfolios
A base year recalculation policy for structural changes
Implementation methodology

How we implement this element

A focused six step methodology calibrated to deliver scope 1, scope 2 and scope 3 greenhouse gas emissions as a working capability rather than a documented compliance artefact.

GHG Inventory Boundary

Working to the GHG Protocol, we set the organisational boundary across operational control, financial control and equity share, and the operational boundary across Scopes 1, 2 and 3.

Scope 1 Calculation

We calculate your direct emissions from stationary combustion, mobile combustion, process emissions and fugitive emissions using emission factors from IPCC, EPA or national sources.

Scope 2 Calculation

We calculate your indirect energy emissions and report both the location based and the market based figures per the GHG Protocol Scope 2 Guidance.

Scope 3 Calculation

Working to the Scope 3 Standard, we cover the fifteen categories including purchased goods, capital goods, fuel and energy, upstream transport, waste, business travel, commuting, downstream transport, use of sold products and end of life.

External Assurance

We engage assurance per ISAE 3410 and ISO 14064 3, help you progress from limited to reasonable assurance and align it with the CDP scoring expectations.

Disclosure Authoring

We author MT b to TCFD with the full Scope 1, 2 and 3 inventory, the methodology and the assurance statement, all aligned with IFRS S2 and CSRD ESRS E1.

Deliverables

What we produce

  • A Scope 1, 2 and 3 GHG inventory
  • An external assurance statement
  • Disclosure MT b content to TCFD
  • A Scope 3 category materiality screening per the GHG Protocol
  • An emission factor and methodology register
  • A base year recalculation policy
Common pitfalls

Where execution fails

  • Scope 3 categories arbitrarily excluded with no materiality assessment behind it
  • Scope 2 reported on only a location based or only a market based view rather than both
  • External assurance absent, which invites investor and regulator scrutiny
  • A base year never recalculated after acquisitions or divestments
