About EY

EY is a global leader in assurance, consulting, strategy and transactions, and tax services. We help organizations build a better working world by supporting their transformation and long-term value creation. Joining EY means being part of a collaborative, international environment where innovation, sustainability, and impact guide everything we do.

Opportunity: Manager - Sustainability & Decarbonization (EY-Parthenon EMEIA)

Join a highly strategic team fully dedicated to Decarbonization Strategy, Climate-Tech, and Sustainability, operating across the EMEIA region within EY-Parthenon.
Led by Marco Duso, EY-Parthenon's Global Sustainability Leader, this team plays a key role in shaping the firm's growth agenda in the transformation space and works directly with leading global organizations.

Your key responsibilities:

As a Manager, you will contribute to EY-Parthenon's market impact through several strategic responsibilities:

Market & Business Development

• Drive origination and market development across decarbonization, energy transition, climate-tech and sustainability-linked transformation themes.
• Build and refine commercial offerings, value propositions and go-to-market approaches in priority sectors and technologies.

Offer & Solution Development

• Strengthen EY-Parthenon's Sustainability & Decarbonization offerings by contributing expertise in priority topics.
• Develop perspectives, frameworks, and thought leadership.

Targeted Engagement Support

• Provide senior guidance on high-impact transformation programs requiring deep sustainability or climate-tech expertise.
• Shape direction, challenge assumptions, and provide solution depth on multi-workstream client engagements.

Skills and attributes for success

We seek senior professionals who combine consulting-caliber leadership with real-economy sustainability transformation experience across multiple clients.

You bring:

• Experience steering large, multi-workstream transition or decarbonization programs for corporates, investors or public entities.
• Background in top-tier strategy consulting (Project Leader / Principal level) or a senior functional career with significant multi-client advisory exposure.
• Ability to engage credibly at C-suite level and generate commercial momentum in emerging sustainability domains.
• Strong ability to synthesize complex technical topics and guide cross-functional teams across technology, operations, finance and strategy.
• Expertise in at least one advanced topic, such as:
• Adaptation & infrastructure resilience
• Industrial decarbonization (electrification, energy efficiency, low-carbon operating models, value chains, etc.)
• AI use cases in energy and decarbonization
• Climate-tech and/or deep-tech scaling (advanced materials, energy storage, industrial process optimization)

Your mindset:

• Passion for climate and sustainability - this is a mission-driven team.
• Leadership across 15-20+ sustainability or energy transition engagements with clear strategic influence.
• Commercial, opportunity-shaping mindset with comfort in developing new offerings and building relationships.
• Experience across varied project types (strategy, transformation, operations, transaction support, due diligence).
• Ability to work effectively across geographies, sectors and EY service lines to build integrated solutions.
• Advanced degree preferred (MBA, MSc, MEng, PhD), especially related to energy systems, industrial systems, climate or climate-tech.

What Makes This Role Unique

This is not a traditional delivery-focused role.
You will join a dedicated transformation team responsible for shaping EY-Parthenon's sustainability strategy, solutions and growth engine across EMEIA, while selectively applying your expertise to high-impact client engagements.

It is a unique opportunity to influence how some of the world's most prominent organizations navigate their sustainability and decarbonization journeys.
