The Institute of Sustainability & Environmental Professionals (ISEP) has officially announced the launch of a comprehensive, multi-tier Register of Carbon Accountants and Auditors (RCAA). Designed to establish a rigorous professional benchmark, the new system aims to clearly communicate the qualifications, competence, and expertise of carbon accounting professionals across the corporate and financial landscapes.
The introduction of the RCAA comes at a critical juncture for the environmental, social, and governance (ESG) sector. As global demand for robust, verifiable carbon data surges and regulatory reporting requirements become more widespread, organizations face unprecedented pressure to accurately measure, disclose, and reduce their greenhouse gas emissions. At the same time, standardized climate reporting frameworks—such as those promulgated by the International Sustainability Standards Board (ISSB)—continue to expand globally. Despite this heightened focus on accountability, the approaches, methodologies, and levels of professional expertise among individuals conducting carbon calculations have historically varied significantly. The new accreditation system is intended to bridge this gap, bringing much-needed standardization and trust to the discipline.
Speaking on the launch of the registry, ISEP CEO Sarah Mukherjee emphasized the vital importance of reliable data in corporate climate strategies. As organizations across all sectors look to decarbonize and systematically reduce their environmental footprint, Mukherjee noted that it is essential for stakeholders to have seamless access to independently assessed, high-quality data and professional advice.
The framework for the RCAA was developed in close collaboration with the Carbon Accounting Alliance (CAA), ensuring that the standards reflect the practical needs of the industry. According to ISEP, the register is intended to give organizations, corporate leaders, regulatory bodies, and various reporting schemes a heightened level of confidence regarding the qualifications and hands-on experience of the professionals tasked with calculating and auditing corporate carbon footprints.
To accommodate professionals at different stages of their careers, the RCAA encompasses a carefully structured hierarchy of professional tiers. The system features the already-launched entry-level Technical Associate grade, which is designed to recognize foundational knowledge in the field. This is complemented by two newly introduced levels: the Registered Practitioner and the Principal Carbon Accountant. These advanced tiers reflect progressively greater levels of professional responsibility, technical expertise, and operational experience. In addition to these roles, ISEP has confirmed that a dedicated Registered Carbon Accounting Auditor grade is planned for the future, which will further expand the scope of the register to cover verification and assurance functions.
By establishing the RCAA, ISEP hopes to achieve several core objectives for the sustainability sector. Chief among these is the promotion of effective, reliable carbon accounting practices by setting high-quality standards rooted in the real-world knowledge and experience of seasoned professionals. Furthermore, the registry is expected to significantly enhance the professional credibility of registered carbon accountants and auditors. By creating a formalized and transparent system of recognition, the initiative also provides a clearly defined career pathway for carbon accountants, opening up tangible opportunities for professional growth and recognition within a rapidly evolving job market.
Andrew Griffiths, Co-Founder of the Carbon Accounting Alliance, underscored the significance of the rollout for the wider industry. With all three core levels of professional registration for carbon accountants now fully launched, Griffiths pointed out that the industry finally possesses a robust and transparent approach to the formal qualification of credible carbon foot-printing expertise. He added that this framework will ultimately provide both practitioners and the end-users of corporate data with absolute confidence in the skills and competence of the individuals undertaking complex emissions calculations.
