Company Description

PNZ Advisory (formerly Arete Zero Carbon) is a carbon management and sustainability consultancy founded in 2021 by Dr Stephen Finnegan. Our mission is to make sustainability achievable and to help future-proof organisations of all shapes and sizes.

We partner with clients across sectors to deliver innovative, tailored carbon solutions - from emissions reporting and decarbonisation planning to ESG guidance and compliance. But we’re more than just consultants. We’re educators, enablers, and thought leaders, empowering organisations with the knowledge and tools to act on climate change and lead the journey to net zero.

Role Description

We’re hiring a Sustainability Data Analyst with 1–3 years of experience to join our growing team. This is a full-time, hybrid position based in Birchwood, Warrington, with flexibility for remote working.

In this role, you'll lead on data-focused workstreams across client projects, helping businesses measure their carbon footprints, analyse their data, and shape their net zero strategies. You’ll work in a supportive, fast-paced team where your insights make a real impact.

If you're ready to step up from a graduate-level position and want to take ownership of meaningful sustainability work, this could be for you.

Salary: £30,000 – £35,000 per year (depending on experience)

• Conduct GHG emissions assessments (Scopes 1, 2 and 3) in line with the GHG Protocol
• Lead data workstreams, advising on methodologies and carbon accounting principles

• Conduct research and extract credible data sources for bespoke client needs
• Support carbon assurance and data validation for audit readiness
• Create client-ready reports, dashboards, and data visualisations
• Contribute to life cycle assessments (LCAs) for products and services
• Participate in client meetings/workshops, translating complex analysis into clear insights
• Provide QA and technical support to junior analysts
• Continuously improve data systems and internal workflows

Desirable

• Masters degree in Sustainability, Environmental Science, Data Science, Statistics, or a related field
