Sustainability Data & Carbon Accounting Consultant

3R Sustainability is the premier choice for businesses looking to turn sustainability into a strategic advantage. As a full-service sustainability solutions provider, we help organizations enhance efficiency, reduce risk, and drive value by working to seamlessly embed sustainability into business operations. Our approach is rooted in true partnership. Our expert consultants guide, educate, and engage companies throughout the entire process. We also practice what we advise: 3R is a Certified B Corp, a certified Women’s Business Enterprise (WBE), and an EcoVadis Platinum medalist.

This spirit of partnership defines our internal culture as well. We are a team of passionate, mission-driven professionals who genuinely value and support one another. We pride ourselves on fostering a truly collaborative atmosphere where we work together to make a real impact. If you are looking for a place to grow, do meaningful work, and be part of a close-knit, supportive community, 3R is the place for you.

You will help clients interpret emissions data across Scopes 1, 2, and 3 and translate findings into practical emissions-reduction strategies. Your work will include supporting greenhouse gas (GHG) inventories and related analyses, as well as product carbon footprints (PCFs) and life cycle assessments (LCAs). You will also help clients organize and evaluate data to prepare for compliance with evolving product and packaging regulations, including the EU Packaging and Packaging Waste Regulation (PPWR) and Extended Producer Responsibility (EPR) requirements.

You will work with colleagues in Climate, Product and Packaging, and other service areas. Day to day, that means collecting and organizing client data, working in our inventory tools, checking results, and making technical findings clear and useful for project teams and clients.
