As a Carbon Management Data Analyst, you will take ownership of the integrity and flow of environmental data across a global organization. You will spend your time validating quarterly carbon inputs, detecting anomalies, and ensuring that the raw data provided by various international branches is accurate and ready for high-level reporting. This is a technical, detail-heavy role that serves as the backbone for the company’s decarbonization tracking.

This position is vital because it bridges the gap between raw facility operations and corporate climate targets. By maintaining rigorous data quality, you enable country managers to make informed decisions on emissions reductions and ensure the group remains audit-ready in an era of tightening ESG regulations. Your work directly quantifies the environmental footprint of thousands of managed workplaces worldwide.

This suits someone who possesses a methodical mindset and finds professional satisfaction in the precision of structured datasets. You should be comfortable with repetitive validation tasks and have the technical stamina to handle large-scale environmental information accurately.

Job-FAQs

What are the main missions and responsibilities of this role?

The primary focus of this role is to manage the integrity of environmental datasets across the organization's global operations. You will be responsible for the day-to-day validation of carbon data, ensuring that every entry from various regions is accurate and formatted correctly for downstream analysis. This involves implementing standardized validation checks to catch errors before they reach the reporting stage. Beyond data cleaning, you will play a critical role in supporting audit-readiness. You will organize documentation and evidence that proves the validity of the company's carbon claims, providing essential support to country-level decarbonization managers. Your goal is to create a seamless, high-quality data pipeline that reflects the company's actual environmental impact.

Key learning opportunities for this job

In this role, you will gain deep expertise in Greenhouse Gas (GHG) Protocol standards and corporate carbon accounting within a large-scale service environment. Dealing with data from over 30 countries provides a unique perspective on the complexities of international environmental reporting and the nuances of regional emission factors. Additionally, you will sharpen your technical skills in Power BI and SQL within a professional ESG context. You will learn how to build robust anomaly detection workflows and how to prepare corporate datasets for external third-party audits, which is an increasingly valuable skill set in the current regulatory landscape.

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

The ideal candidate holds a Master's degree in Environmental Science or Data Science, combining a passion for sustainability with a high level of technical literacy. You should have at least three years of experience managing complex datasets, ideally related to carbon footprints or environmental performance indicators. Technical proficiency in Excel is non-negotiable, and a working knowledge of SQL and Power BI is essential for extracting and visualizing data. Because much of the work involves meticulous validation and error-checking, we look for individuals who are detail-oriented, patient, and able to maintain high standards of accuracy even when handling large, repetitive data tasks.

Advice to stand out and make a successful application

To stand out, emphasize your experience with data cleaning and validation workflows rather than just high-level analysis. Show that you understand the 'messiness' of real-world environmental data and explain how you have previously identified and corrected errors in complex spreadsheets or databases. In your cover letter, demonstrate an understanding of the facilities management industry and the specific challenges of tracking emissions across diverse services like cleaning, catering, and technical maintenance. Highlighting any experience you have with audit preparation or regulatory compliance frameworks will also give you a significant advantage.

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

This role is central to the company's decarbonization strategy. While many roles focus on high-level policy, this position deals with the granular reality of carbon management. You will likely focus on Scope 1, 2, and 3 emissions resulting from global operations, helping the company track its progress toward net-zero commitments. Your work will ensure that sustainability reports are grounded in reliable data. This focus on data quality is essential for the company to maintain its reputation and comply with evolving ESG disclosure requirements, such as the CSRD, which demand high levels of transparency and data traceability.

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

The most significant challenge will be standardizing data from diverse global sources where reporting maturity may vary. You might encounter inconsistent data formats or incomplete submissions from different regions, requiring persistent follow-ups and clear communication to resolve discrepancies. Furthermore, the repetitive nature of validation work requires high mental discipline. Maintaining a high level of attention to detail over long periods, especially during busy quarterly reporting cycles, is crucial to prevent errors from slipping through to the final reports.

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

A typical day might begin with reviewing new data submissions from regional offices and running them through validation scripts. You would spend time investigating anomalies—such as a sudden spike in energy use in a specific country—and reaching out to local managers to verify the figures. Afternoons might be dedicated to optimizing Power BI dashboards or refining SQL queries to improve the efficiency of the data pipeline. You will also participate in team meetings with the Global Technology Solutions group to ensure that the digital tools you use are aligned with the broader corporate IT strategy.

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

This position offers a strong pathway into ESG Data Management or Climate Strategy roles. As companies become more data-driven in their sustainability efforts, the ability to manage complex carbon pipelines is a high-demand skill. You could eventually lead global reporting teams or specialize in ESG digital transformation. There are also opportunities for lateral moves within the ISS Tech Team. Exposure to IoT, sensor data, and AI-driven facility management could allow you to transition into broader digital solution roles that integrate sustainability with smart building technologies.

The main stakeholders you might be interacting with

You will interact frequently with Country Decarbonization Managers, who rely on your validated data for their local reporting and strategy. These interactions will often involve providing feedback on data quality and requesting clarifications on submitted figures. Internally, you will collaborate with the Global Technology Solutions team and IT professionals to maintain the infrastructure supporting the data workflows. You may also provide evidence and support to internal and external auditors who review the company's environmental performance disclosures.
