As the central architect of decarbonization at PORR Group, you will steer the group-wide climate strategy by translating high-level targets into actionable reduction pathways. This role is deeply analytical, requiring you to coordinate international business units to refine forecasts, analyze cost-benefit ratios of green initiatives, and build complex emission models. You will also bridge the gap between sustainability and technology, collaborating with IT to digitize reporting workflows and ensure data integrity across the entire value chain.

Working in the construction industry provides a unique lever for environmental impact, as you directly address one of the most carbon-intensive sectors in the global economy. By optimizing energy data and refining abatement scenarios, your work contributes to the structural transformation of European infrastructure. This is an opportunity to move beyond theory and implement tangible decarbonization solutions that influence the industry’s future footprint.

This suits someone who possesses a highly quantitative mindset and thrives on turning raw data into strategic foresight. You should be a structured project manager who enjoys navigating international stakeholder landscapes and has a flair for digital process design.

Job FAQs

What are the main missions and responsibilities of this role?

The primary mission involves steering the group-wide decarbonization strategy, which means turning abstract climate goals into specific, measurable reduction paths for various business units. You will be responsible for the annual forecast and planning process, ensuring that international subsidiaries are aligned with the group’s overarching environmental ambitions. You will also spend significant time on scenario modeling and data analysis. This includes evaluating energy and emission data to identify deviations and opportunities for improvement. Furthermore, you will lead the digital transformation of sustainability reporting, working closely with IT to design data models that make climate accounting more efficient and transparent.

Key learning opportunities for this job

Candidates will gain deep expertise in large-scale industrial decarbonization within the construction sector, a field that is critical for the global energy transition. You will learn to navigate the complexities of international ESG frameworks while mastering advanced forecasting and scenario analysis techniques applied to real-world infrastructure projects. There is also a strong technical learning curve regarding sustainability digitalization. You will likely enhance your skills in Power BI and specialized carbon accounting software, learning how to translate technical sustainability requirements into robust IT requirements and data-driven management tools.

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

The ideal candidate brings a strong quantitative background, typically from degrees in Industrial Engineering, Environmental Technology, or Business Informatics. You should have a natural affinity for numbers and a critical eye for data plausibility, ensuring that every emission factor and forecast is rooted in reality. Professional experience in climate accounting or project management is essential, ideally within heavy industry or construction. Proficiency in German and English is required to manage international stakeholders, and advanced Excel skills are a must for the complex modeling tasks central to this role.

Advice to stand out and make a successful application

To stand out, emphasize your experience with quantitative modeling and data-driven decision-making. Don't just list sustainability knowledge; demonstrate how you have used data to influence business strategy or operational changes in previous roles. Given the construction focus, show an understanding of the specific carbon challenges in building materials and infrastructure. Mentioning your familiarity with international reporting standards or your ability to communicate technical findings to non-technical managers will highlight your readiness for PORR's international corporate environment.

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

The role focuses intensely on the decarbonization of the value chain. You will be looking at Scope 1, 2, and 3 emissions, focusing on how a construction giant can reduce its footprint through energy efficiency, material innovation, and logistical optimizations. Additionally, there is a heavy focus on ESG data governance. By digitizing workflows, the role ensures that sustainability performance is treated with the same rigor as financial performance, supporting the company's long-term transparency and compliance goals.

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

One of the main challenges is data fragmentation across different international units and construction sites. Harmonizing this information into a single, reliable group-wide forecast requires persistence and high attention to detail. You may also face the challenge of balancing climate ambitions with economic realities. Proposing reduction measures that are both environmentally impactful and financially viable within the competitive construction market requires sophisticated analytical modeling and persuasive communication.

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

A typical day might begin with analyzing emission activity data to identify trends or anomalies in a specific region. You could then move into a meeting with the IT department to discuss the rollout of a new digital tool for tracking energy consumption across international subsidiaries. Afternoons are often dedicated to stakeholder management, perhaps presenting a forecast model to department heads or refining the group’s decarbonization roadmap. The day usually ends with documentation or preparation of decision papers for the board, ensuring all technical data is translated into clear strategic insights.

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

As a central expert in a high-priority strategic area, this role offers significant visibility to senior management and the executive board. Successful execution could lead to leadership roles within the sustainability department or strategic positions in corporate development. There is also room to become a thought leader in green construction, representing PORR in industry-wide forums or working groups focused on the decarbonization of the built environment, which is a rapidly growing and highly valued niche.

The main stakeholders you might be interacting with

You will interact frequently with international unit managers and site leads to coordinate reduction measures. Internally, your closest collaborators will be the IT and Data Management teams, who help build the infrastructure for your analysis. Externally and at the corporate level, you will provide critical information to Senior Executives and ESG committees. You may also engage with external auditors or consultants during reporting cycles to ensure the group’s decarbonization efforts meet regulatory and voluntary standards.
