SCOPE 3 - UNLOCK
SCALING SUPPLY CHAIN
CLIMATE ACTION INITIATIVE

As Scope 3 disclosure becomes a regulatory imperative, navigating supply chain data is a shared challenge. Join our "Scope 3 Unlock" Introductory Webinar on 14 May! Experts from WWF, CDP, and TÜV Rheinland will unpack actions and reporting gaps with practical solutions to help your business and suppliers turn climate insights into tangible action. Register now!

OVERVIEW

The Scope 3 UNLOCK – Scaling Supply Chain Climate Action Initiative is designed by WWF-Hong Kong to help corporates measure, disclose, and reduce Scope 3 emissions across their operations and supply chains.

Building on the success of the Low Carbon Manufacturing Programme (LCMP), this initiative extends climate action beyond Scope 1 and 2 emissions to address the largest share of corporate carbon footprints.

OBJECTIVES

The Scope 3 Unlock initiative enhances companies’ understanding of Scope 3¹emissions and enables collaboration with suppliers to prepare for critical challenges — ranging from data gaps and inconsistent internal processes² to credible reporting. It provides tools adapted from proven LCMP and LOOP^PLUS experiences, alongside collaborative frameworks, capacity-building support, and progress and peer sharing.

The initiative kickstarts shared action through pledges, readiness self-assessment, workshops, a collective learning and resource hub — scaling value-chain collaboration to unlock supplier-specific activity-based emissions insights beyond generic spend-based estimates.

KEY BENEFITS

Joining Scope 3 Unlock helps companies contribute to the city’s pathway towards net zero emissions by 2050.

Respond to regulations: Fulfil global and local climate related regulatory requirements and enhance readiness for evolving international standards and investor attention with accuracy, consistency and credibility.
Navigate Scope 3 with confidence: Access practical guidance aligned with expanding regulatory expectations to identify and prioritise high impact value-chain emissions, building on your existing climate efforts.
Access proven tools immediately: Use LCMP and LOOP^PLUS checklists, questionnaires, and frameworks to support reliable Scope 3 information collection and improve supplier engagement.
Build strong partnerships: Engage suppliers through workshops and online resources to improve the quality of emissions information and scale climate solutions.
Multiply collective impact: Collaborate with peers to enhance visibility into emissions information and sources across value-chains through shared learning.
Stand out and attract growth: Differentiate in global competition and strengthen market appeal by aligning with growing customer demand for credible sustainability practices.
Demonstrate vision to investors: Showcase long-term resilience and forward-looking strategy to shareholders and investors through transparent Scope 3 engagement and reporting.

¹ Scope 3 emissions are the indirect greenhouse gas emissions across a company’s value-chain — both upstream and downstream — and often represent the largest share of a company’s carbon footprint, making them critical for credible climate strategies and disclosures.

² Internal processes are the systems and routines inside a company that govern how climate- and carbon-related work is done. They typically include things like:

How you collect and validate data from different departments and suppliers (e.g. finance, procurement, logistics, operations).
How responsibilities and approvals are assigned (who owns which category of Scope 3, who signs off on numbers, who talks to suppliers).
How often you review and update emissions data and assumptions.
How you integrate climate topics into procurement, budgeting, and risk management (e.g. including emissions in supplier selection, contract clauses, KPIs).

The initiative is built on WWF’s long established Low Carbon Manufacturing Programme (LCMP) which aims to cut carbon emissions generated by manufacturing facilities and develop environmental social governance for manufacturers.

In 2024-25, LCMP has helped factories avoided approximately 341,514 tonnes of carbon emissions, equivalent to 14,848,438 trees one year to absorb that amount of carbon emissions.

In recent years, several manufacturing companies participating in LCMP have begun collecting Scope 3 emissions data, such as materials purchasing from their supply chain and upstream transportation. This reflects a growing focus among companies on understanding and managing their Scope 3 carbon footprint.

How It Works

Companies follow a four‑step approach, beginning with an activation pledge and a self‑assessment to diagnose Scope 3 priorities and readiness. Capacity is built through workshops and a resource hub, with regular progress reviews to support continuous improvement and collective impact.

Implementation Timeline

Pledge to Activate Scope 3 Action (March–June, 2026)

Participating companies complete and return the activation pledge to WWF by June, signalling commitment to begin engagement.

Self‑Assessment & Readiness Diagnostic (June–August, 2026)

Pledged companies will complete a self‑assessment using a structured checklist to evaluate governance arrangements, data readiness, supplier engagement capabilities, and priority Scope 3 categories, and submit the completed assessment to WWF by August.

Capacity Building Workshops (September, 2026) & Online Resource Hub

Pledged companies will be invited to in‑person workshops held in September, providing access to practical tools, shared resources, supplier-engagement materials, data-collection guidance, Scope 3 emissions categories, and case studies.

First-Year Review & Insights (November–December, 2026)

Progress updates are consolidated, with insights and learnings reviewed and published in November–December to support ongoing engagement and collective impact.
