Sustainable Development Manager

Key Responsibilities Climate & Carbon Management • Own the Group GHG inventory (Scope 1, Scope 2, and material Scope 3 categories) — set the data boundary, run annual collection, and secure third-party verification. • Translate the Climate Strategy into a costed decarbonisation roadmap with annual reduction targets by business unit. • Lead abatement initiatives across energy efficiency, renewable energy, circular economy, and behaviour change — build the business case, track abatement delivered, and report cost per tonne. Reporting & Disclosure • Run the annual disclosure cycle end-to-end against IFRS S1/S2, GRI, TCFD, and the FTSE Russell ESG assessment — owning the calendar, data controls, and sign-off path. • Build and maintain the sustainability data architecture — defined metrics, named data owners in each function, and an audit trail sufficient for external assurance. • Lead the materiality assessment refresh and translate the results into strategy priorities and disclosure scope. Project & Programme Delivery • Plan and deliver the sustainability project portfolio — scope, budget, timeline, and resourcing — escalating trade-offs early rather than at deadline. • Track portfolio performance against SD KPIs and report variance, with corrective action, to the Head of Sustainability monthly. Stakeholder Engagement & Capability Building • Act as sustainability business partner to operations, procurement, HR, and finance — securing data, commitment, and delivery from functions outside direct authority. • Prepare and present sustainability content to the executive committee, investors, rating agencies, customers, and regulators. • Monitor emerging regulation and market standards (e.g., CBAM, SEC/SET requirements, IFRS updates) and brief management on the business implications. • Build sustainability literacy across the organisation through training, toolkits, and internal communications. Qualifications Required • Bachelor's or Master's degree in Environmental Science, Engineering, Sustainability, Business, or a related field. • Minimum 5 years' experience in corporate sustainability, ESG reporting, or environmental project management. • Experience in leading double-materiality assessment and structured stakeholder engagement. • Demonstrated ownership of a corporate GHG inventory (Scope 1, 2, and Scope 3) — including data collection design and external verification. • Hands-on experience producing a published sustainability report against a recognised framework (GRI, IFRS S1/S2, TCFD, or equivalent). • Working knowledge of the GHG Protocol and at least one ESG rating or assessment process (FTSE Russell, DJSI/CSA, CDP, or SET ESG Ratings). • Experience in retail business is preferred. • Proven project management capability — control of budget, timeline, and resources on multi-stakeholder initiatives. • Strong storytelling skills, with the ability to communicate sustainability topics clearly and effectively. • Professional working proficiency in Thai and English, written and spoken — disclosures and management reporting are produced in both.
