About the team

You’ll join Greenly's Climate Delivery team, a group of customer-obsessed Climate Strategy Experts dedicated to guiding clients through their most strategic climate and sustainability challenges. We deliver high-quality climate projects - carbon assessments, lifecycle analyses (LCA), SBTi trajectories, CSRD support - and help organizations turn data and regulations into clear, actionable decisions. As a team, we: Combine analytical rigor with a strong customer success mindset. Act as trusted advisors, not just technical analysts. Thrive in a fast-moving, collaborative environment, sharing methods, scripts, and lessons learned. Work closely with Customer Support, Product, Sales, and Marketing to ensure our clients succeed and our methodologies stay robust. It's one of Greenly's most influential client-facing teams: high expectations, complex projects, and real impact on both client outcomes and product evolution.

About the role

As a Climate Data Analyst Intern, you will join Greenly’s Climate Delivery team for a 6-month internship. You will be part of real delivery operations from day one: not shadowing, but contributing. You’ll work hand in hand with senior Climate Strategy Experts on client projects and on internal process improvements, using our software and internal tools to calculate carbon emissions data. You will help our clients get a complete picture of their carbon footprint and make better choices to reduce their impact. Please note that this is a full-time 6-month internship based in Paris.

Tasks and responsibilities

• Your primary responsibility is to contribute to the end-to-end delivery of climate projects, and to ensure the quality of the data behind them, working closely with our Climate Strategy Experts.
• Day to day, you will: Get involved in client projects to support project managers in delivering high-quality work: platform setup, specific analyses, benchmarks, quantification of reduction actions, and more.
• Perform data quality checks on GHG assessments and LCA projects delivered to clients.
• Help design tools and templates enabling greater client autonomy on quality checks.
• Consolidate and help update the mitigation plans on our platform.
• Take ownership of data collection, consistency checks, and analysis for a portfolio of clients.
• Ensure the quality of our data analysis: apply the right calculation methodology and make sure clients can understand the logic behind it.
• Share feedback with our Product team to improve processes and tools.

Success at the end of your internship

You have autonomously managed quality checks and delivered reliable outputs for real client projects. You have led or co-led at least several result presentation meetings. You have contributed a concrete process improvement tool or template used by the team. Clients and colleagues see you as autonomous, rigorous, reliable, and proactive.

Skills needed to succeed

• Education: Currently pursuing or recently completed a Master’s degree in engineering, environmental sciences, data, or a related field.
• Knowledge of GHG accounting: Curiosity about climate regulation and carbon accounting (GHG Protocol, LCA, SBTi, CSRD…), from your studies or other experience.
• Detail-oriented problem solver: You are meticulous and enjoy digging into a dataset.
• Tech skills: Solid Excel skills (mandatory); Python, SQL or BI tools are a strong plus.
• AI Proficiency: You are comfortable working with AI tools such as Claude or Gemini.
• Communication: You can explain a complex methodology to a non-expert, clearly and simply.
• Language skills: Bilingual in French and English (C1/C1), both verbal and written.
• You may also have: Prior exposure to climate frameworks or sustainability consulting. Experience with Python/SQL/BI tools (nice to have).
• You might not be a fit if: You find fast-paced environments with shifting priorities overwhelming.
