Carbon Accountant in Belfast

The Change Impact and wider group is a 4th Sector business focused on delivering both commercial and environmental impact through action. We work closely with businesses across the UK, Germany, and further internationally, helping them unlock value from innovation while delivering measurable sustainability outcomes.

This role sits within our impact and sustainability division, where we go beyond tracking emissions. We work with clients to develop practical, real-world solutions; one example is enabling a client to transform materials that would otherwise be burned into more environmentally and commercially valuable input for batteries. This work involves partnering with sometimes the ‘worst polluter’ businesses to develop practical solutions that reduce emissions and create new value chains; converting waste materials into usable industrial inputs.

Within sustainability, we support clients in carbon accounting, regulatory reporting, and emissions reduction, ensuring they can accurately measure, manage, and reduce their environmental impact in line with evolving regulatory requirements. Our work spans multiple sectors and geographies, supporting both scaling SMEs and established organisations.

This is a full-time, office-based role (Hybrid Flexibility once settled) in Belfast for a Carbon Accountant. This is a delivery-focused role responsible for the calculation, analysis, and reporting of carbon emissions across a portfolio of clients. The role centres on collecting and validating energy and operational data, calculating Scope 1, 2 and 3 emissions, identifying appropriate emissions factors, and producing structured, compliant outputs.

A key aspect of the role is supporting clients in meeting ongoing regulatory obligations, particularly CBAM (Carbon Border Adjustment Mechanism). This includes tracking embedded emissions, maintaining compliant datasets, and supporting the preparation and submission of required reports within defined reporting periods. You will work across multiple client organisations, including those with multi-national structures, requiring coordination across divisions and, in some cases, regions to gather accurate data.

The role combines technical delivery with ongoing client interaction, including presenting outputs where required. You will also support colleagues in ESG reporting and the provision of environmental insights.
