Sustainability Internship – ESG & Climate 2026

Your Mission

You will be working alongside our consultants on live client projects, getting hands-on with the kind of work that actually moves the needle on sustainability. As part of your time with us, you will also take on a personal internship mission: a defined project you can call your own, develop, and finish with something concrete to show for it. On top of that, you will learn fast, contribute meaningfully, and be part of a team that does its work passionately!

What you will deliver:

• Support ESG assessments, carbon footprint calculations, and sustainability gap analyses for clients across sectors.
• Build quantitative emissions models — collecting, cleaning, and interpreting large volumes of activity data to produce accurate Scope 1, 2, and 3 inventories.
• Support the team in developing client-ready sustainability roadmaps and improvement plans, grounded in data and aligned with relevant reporting frameworks.
• Apply and learn assessment methodologies, including EcoVadis, B Corp, CDP, and reporting standards such as GRI, UNGC, and ESRS.
• Produce well-structured reports, presentations, and data visualisations that translate technical findings into clear, actionable recommendations.
• Support project managers on client-facing calls and assist with preparing client deliverables.
• Build and maintain internal knowledge databases, capturing key regulations, data sources, and methodological insights to strengthen collective expertise.
• Research emerging sustainability topics and contribute creative, evidence-based approaches to complex client challenges.
