Sustainability Intelligence - Building a Trustworthy Scope 3 Ecosystem at Scale

Sus-Intel is LSEG’s sustainability intelligence platform that helps corporates measure, manage, and report carbon emissions across their value chains - driving transparency, compliance, and data-driven climate action.

Project Overview

I led the end-to-end product development and experience design of the Scope 3 Ecosystem - a complete re-architecture of how corporates estimate supply-chain emissions, engage suppliers, reuse reported data, and align everything to disclosure-ready reporting periods.

What started as disconnected tools became a persistent, traceable, multi-entity system used by thousands of suppliers and hundreds of corporates across APAC.

Scope 3 Emissions : Scope 3 represents the emissions a company doesn’t directly control but is responsible for across its supply chain — often 70–90% of total emissions.

The Solution

1. Reporting Periods (RP) : A platform-wide anchor that ties all emissions, engagements, and calculations to the right disclosure cycle - enabling multi-year analytics and regulatory reporting.

2. Continuous Scope 3 Estimation : Removed re-upload cycles.
Corporates can now carry forward suppliers, update only what changed, and maintain continuity between cycles.

3. Connected Supplier Engagement : Engagements now directly link back to supplier profiles, their estimation history, and past reported data — eliminating duplication and giving corporates a 360° view.

4. Central Supplier Record : A persistent database storing:

• supplier identity

• emissions history

• engagement timeline

• shared data

• lineage

• authoritative sources

This unlocked reuse and data integrity across the system.

5. Multi-Corporate Data Sharing : Suppliers can share previously reported emissions with any corporate they work with - reducing survey fatigue and boosting data quality.

The Problem

Scope 3 typically represents 70–90% of a company’s total emissions.
Yet it’s also the least standardised, most data-fragmented, and most supplier-dependent layer of climate reporting.

The previous platform made this worse:

• No reporting periods, so emissions couldn’t be tied to any year or disclosure cycle.

• Scope 3 estimation had to start from scratch every time with full supplier re-uploads.

• Supplier engagement was disconnected from supplier profiles, estimates, and reporting.

• No central supplier database — data couldn’t be reused or tracked across engagements.

• Reported data couldn’t flow into analytics or be shared across corporates.

• Suppliers received duplicate survey requests with no visibility or reuse of past submissions.

The Core Product Question

"How might we build a connected platform that enables corporates to seamlessly estimate, collect, and report Scope 3 emissions - aligning supplier and emissions data to reporting periods — so they can meet sustainability reporting requirements with accuracy, traceability, and trust?"

My Role

Product Manager:
Supplier Management • Data Sharing • Reporting Periods • Settings

UX Lead:
Unified flows across estimation, engagement, reporting, and data models.

Cross-functional leadership:
Partnered with 2 PMs, 2 data architects, and 3 engineering squads (APAC & EU) to align object models, backend rules, user journeys, and delivery.

Impact

• 0 → 1 platform build in Year 1 -launched core Scope 3 capability from concept to production.

• 318% YoY adoption growth — scaled from 184 → 900+ corporates within 12 months.

• Post-revamp engagement lift from ~60 → 200+ active corporates, sustaining 72.9% activation across 180+ organisations.

• Laid the ecosystem foundation for new revenue streams, enabling modular add-ons for estimation, supplier management & benchmarking.

• Designed compliance-ready architectures aligned with regional disclosure frameworks — built for auditability, comparability & scale.

• Improved onboarding flows → faster time-to-value for suppliers & corporates, accelerating activation across user segments.

• Partner-driven scale model enabled exchanges/institutions to onboard 1,000+ corporates with a single integration.

• Embedded go-to-market adoption with Sales & Exchanges — workshops, demos, onboarding collateral → rapid market penetration.

The Hidden Complexity I Solved

Beyond building features, this project required designing the logic that makes a Scope 3 platform work:

1. A persistent multi-cycle data model I defined how suppliers, engagements, estimates, reported data, and reporting periods relate across years - building a system that remembers, compares, and evolves with each new submission.

2. Data lineage & traceability

Rules for:

• what counts as “authoritative”

• when reported data overrides estimates

• how to handle partial data

• how shared data persists across corporates

This became the backbone of trust.

3. Multi-channel user journeys

Mapped touchpoints across:

• corporate internal workflows

• supplier external workflows

• invitations

• reporting cycles

• data sharing

• analytics

• resubmissions

Every journey had to work independently and connect seamlessly upstream and downstream.

4. Governance logic

Designed the states and transitions for:

• suppliers across engagements

• estimates across reporting periods

• outdated emissions

• resubmission flows

• cross-corporate data sharing permissions

These constraints were critical for compliance readiness.

5. Platform orchestration

Structured how modules talk to each other:
Emissions Calculator → Supplier Management & Engagement → Reporting

This unified the product for the first time.

MVP Highlights

• Centralized supplier database

• Engagement module with configurable assessments

• Supplier account creation with secure sharing

• Combined “Estimated vs Reported” emissions views

• Activation & completeness analytics

• Multi-year RP-linked emissions dashboard
