Sustainability & Climate Data Lead

Mars • United States • Added on Oct 30, 2026
Apply →

This role leads the technical data work behind Mars Snacking’s climate decisions. The person will build and govern supplier-specific greenhouse gas impact factors, check their methods and quality, and make sure the resulting information can support annual reporting and choices about ingredients and product formulations. It is an individual-contributor position with wide internal and external collaboration.

The work connects climate targets to the agricultural and ingredient data used to measure progress. Mars describes a value-chain Net Zero commitment by 2050, so credible supplier information, farm measurement and consistent accounting methods matter to tracking emissions and assessing lower-footprint products. The role also sits where evolving climate standards meet practical sourcing and research decisions.

This suits someone with substantial experience in sustainability measurement who can combine GHG accounting and quantitative analysis with careful project delivery. A strong candidate will be comfortable reviewing technical evidence, resolving data problems and explaining complex methods clearly to colleagues across sourcing, research and reporting.

Job FAQs

What are the main missions and responsibilities of this role?

The role owns the development and annual quality assurance of supplier-specific GHG impact factors, from collecting sourcing data through reviewing analyses and integrating validated results into reporting. It also maintains ingredient mapping and checks that the database is complete and audit-ready. A further mission is to review farm measurement tools and life cycle assessment methods, interpret changing climate accounting standards, and advise Research & Development on ingredients and formulations. Project governance includes spotting delays or data risks and coordinating recovery plans across Mars Snacking and partners.

Key learning opportunities for this job

The position could deepen expertise in GHG accounting topics such as removals, farm monitoring and verification, co-product allocation, traceability and mass balance. Reviewing life cycle assessments and supplier data may also build practical knowledge of agricultural measurement and the limits of primary data. Working across sourcing, research, reporting and external specialists could develop the ability to translate accounting methods into business decisions. The posting mentions learning and development through Mars University, though it does not specify role-specific courses or certifications.

How does the ideal candidate look like (experience, skills)?

The posting calls for a relevant bachelor's degree and at least five years of sustainability experience, including substantial quantitative data work. A graduate degree is an advantage, while experience with GHG measurement, MRV systems and standards such as the GHG Protocol is directly relevant. The candidate should be able to assess technical evidence, manage interdependent projects and present analysis clearly. Excel, PowerPoint and digital data-management systems are specified; collaboration across functions and with external partners is also important. The description does not name a required certification.

Advice to stand out and make a successful application

Use examples that connect a technical climate method to a dependable reporting outcome. Explain the data source, accounting choices, validation or verification steps, and how you handled gaps or uncertainty, especially for supplier or farm-level information. For interviews, prepare a concise example of recovering a delayed data project without reducing its quality. It may also help to discuss how you would explain a complex issue such as mass balance versus traceability to sourcing or Research & Development colleagues, and how the resulting evidence could inform ingredient decisions.

What aspects of the company's sustainability is this role likely to focus on?

The role is likely to focus on value-chain climate measurement, particularly the agricultural and ingredient data used in Mars Snacking's GHG accounting. Supplier-specific impact factors and farm MRV methods are central to making reported emissions more traceable and auditable. The work also supports Mars's stated Net Zero value-chain target for 2050 by improving the evidence used to track progress and assess climate effects of new ingredients or formulations. The job mentions related measures such as soil health, water and biodiversity as areas of relevant MRV expertise, but its main remit is climate data.

What are the main challenges someone in this role might face?

Supplier and farm data may vary in completeness, quality and measurement approach, making consistent impact factors difficult to establish. The role must assess methods such as allocation, mass balance and traceability while preserving credible, reviewable reporting. Climate accounting standards are changing, and data projects can fall behind schedule. Balancing technical rigor, annual reporting deadlines and the practical needs of sourcing and product teams is likely to require clear decisions and persistent coordination.

How could a typical day look like for someone in this position?

A day could include reviewing supplier data or an impact-factor analysis, checking assumptions with a consultant, and updating the status of ingredient coverage and validation. The person may also resolve a data or schedule issue that could affect annual reporting. Other work could involve discussing climate accounting standards with internal experts, advising Research & Development on a formulation question, or translating results into a concise presentation for decision-makers. The mix would likely shift with reporting deadlines and project risks.

What are the opportunities for professional growth and development in this role?

The role could build deeper expertise in climate accounting, agricultural measurement, life cycle assessment and supplier data governance. Its cross-functional scope may also develop project leadership and the ability to influence product and sourcing decisions through technical analysis. Further growth could come through broader responsibility for shared methods across business segments or participation in Healthy Planet operating-model work. The posting mentions Mars University and learning and development, but does not specify a promotion path or formal certification.

The main stakeholders you might be interacting with

Key internal partners are likely to include sourcing teams collecting supplier information, Research & Development teams assessing ingredients and formulations, and colleagues responsible for GHG reporting and the wider Healthy Planet operating model. Segment experts may work together to align methods. External interactions include suppliers, consultants reviewing farm tools and life cycle assessments, and industry experts tracking climate accounting practices. These relationships involve gathering evidence, reviewing technical methods and resolving data or delivery issues.
