Newcastle, Australia | April 14, 2026 – MCi Carbon today announces that its Chief Technology Officer and Co-founder, Dr. Mark Rayson, has been officially appointed as a Lead Author for the Intergovernmental Panel on Climate Change (IPCC). His role is to develop the 2027 Methodology Report on Carbon Dioxide Removal (CDR) Technologies and Carbon Capture, Utilization and Storage (CCUS).
Nominated by the Australian Government’s Department of Climate Change, Energy, the Environment and Water (DCCEEW), Dr. Rayson was selected by the IPCC Task Force on National Greenhouse Gas Inventories (TFI) recognising his expertise in carbon capture systems and emerging carbon dioxide removal technologies.
In this independent role, Dr. Rayson will contribute to the development of new methodological guidance supporting national greenhouse gas inventories, with a particular focus on Carbon Dioxide Capture, Removal, Transport, Utilization and Storage. The report will provide critical frameworks for governments worldwide to accurately account for and integrate CDR and CCUS technologies into climate reporting and policy.
The IPCC Methodology Report is a major international undertaking, involving leading experts from around the world contributing to Chapter 6 and related sections of the report. Dr. Rayson joins a distinguished global cohort of scientists, engineers, and policy experts from leading institutions including the United Nations, the European Commission, world leading universities and climate technology companies. The development process will span 2026–2027 and includes multiple Lead Author Meetings, expert reviews, and government consultations, culminating in formal IPCC acceptance in 2027.
Commenting on the appointment, Dr. Mark Rayson said:
“It is an honour to contribute to the IPCC’s work at a time when scalable carbon removal and carbon utilization solutions are becoming essential to achieving global climate targets. Establishing robust, science-based methodologies is critical to ensuring transparency, credibility, and acceleration of these technologies worldwide.”
From Newcastle to Rome
Dr. Mark Rayson maintains a deep and enduring connection with the University of Newcastle, spanning his academic formation through to his ongoing professional engagement. A graduate of the university, Dr. Rayson earned both his PhD in Chemical Engineering and a combined Bachelor of Chemical Engineering and Business, receiving the University Medal. Dr. Rayson has continued to contribute actively to the institution’s academic community.
In his role as Conjoint Lecturer, he supported the development of future engineers through guest lecturing, supervision of undergraduate and doctoral students, and collaborative research engagement. His sustained involvement reflects a strong commitment to bridging industry and academia.
University of Newcastle Vice-Chancellor Professor Alex Zelinsky AO congratulated Dr Mark Rayson on his appointment.
“Dr Mark Rayson’s appointment as a Lead Author for the IPCC’s 2027 Methodology Report is a significant international honour. Dr Rayson’s expertise as Chief Technology Officer and Co‑founder of MCi Carbon, a spin off company of the University of Newcastle and Orica, demonstrates his expertise in carbon dioxide removal and carbon capture technologies. We are very proud to see University of Newcastle connected research shaping global climate frameworks and real‑world solutions,” Professor Zelinsky said.
The first Lead Author Meeting will be held in Rome from 14–16 April 2026, marking the formal commencement of drafting activities for the report.
