Puro Standard Governance

The Puro Standard is overseen by an independent, external Advisory Board

The Advisory Board was established as an independent entity to host and manage the Puro Standard in October 2021. Prior to this, the Puro Standard was managed by the Original Signatories, a group of 22 companies from six countries, that co-created and managed the original standard and crediting rules since its inception in 2019.



The Advisory Board’s mandate is to ensure high credit-level integrity and robust principles for science-based high-quality carbon removal verification. Puro.earth’s Board of Directors authorized the Advisory Board to:

  1. Independently host, manage and curate the Puro Standard and crediting rules, and
  2. Recommend changes to the Puro Standard and crediting rules to align it to the latest scientific research and policies.

Any and all changes to the Puro Standard and crediting rules are subject to the Advisory Board's approval. Puro.earth's management is responsible for implementing these changes to the rules. The independence of the Advisory Board is enshrined in its Terms of Reference.


Advisory Board Terms of Reference


Advisory Board Members

The Advisory Board brings together a diverse group of experts in the carbon markets with a mix of skills and experience. They are independent and non-executive, meaning they are not Puro.earth employees. However, they are compensated for their work and they have the right to seek any information they require from employees of Puro.earth and/or to seek independent professional advice if needed. The Advisory Board reviews its membership on an annual basis and are responsible for independently nominating, evaluating and appointing new members through a majority vote.

Chairman: Professor Myles Allen

Myles Allen is Professor of Geosystem Science in the School of Geography and the Environment and in the Department of Physics at the University of Oxford. He is Director of the Oxford Net Zero initiative, and credited with first demonstrating, 15 years ago, the need for ‘Net Zero’ carbon dioxide emissions to stop global warming. His research focuses on how human and natural influences on climate contribute to observed climate change and risks of extreme weather and in quantifying their implications for long-range climate forecasts.

Myles has served on the UN’s Intergovernmental Panel on Climate Change (IPCC) as Lead Author on ‘Detection of Climate Change and Attribution of Causes’ for the 3rd Assessment in 2001, as Review Editor on ‘Global Climate Projections’ for the 4th Assessment in 2007, and as Lead Author on ‘Detection and Attribution of Climate Change: from Global to Regional’ for the 5th Assessment in 2013.

Secretary: Mr. Grant McKelvey, Office of general Councel, Nasdaq

Ms. Nikki Batchelor, Director, XPRIZE Carbon Removal

Nikki Batchelor leads the $100M XPRIZE Carbon Removal, a competition supported by the Musk Foundation to drive innovation, scaling, and market adoption of carbon removal solutions. In this capacity she oversees program operations, develops partnerships, designs strategic initiatives, and supports XPRIZE’s work across the energy and climate domain. Previously, she managed operations and impact programs for the five-year $20M NRG COSIA Carbon XPRIZE, including the Circular Carbon Network which aims to catalyze commercial activity and provide market insights for the growing carbontech and carbon removal sectors.

Prior to that, she served as an Innovation Advisor for the U.S. Agency for International Development, designing and executing challenge programs and impact frameworks, as well as managing operations for programs in Iraq and Afghanistan. Additionally, she has worked as a Strategist for NationBuilder, a software start-up developing product and communication strategies and expansion into new markets. Nikki holds an MBA from George Washington University.

Dr. Mai Bui

Dr Mai Bui has over 10 years of experience in research on carbon capture and storage (CCS) technologies. She explores the techno-economic and deployment potential of CCS technologies in a range of different applications, including power, industry and for CO2 removal from the atmosphere (i.e., bioenergy with CCS, or direct air capture technologies). She has first-hand experience in designing experimental test campaigns for both pilot-scale and demonstration-scale CCS plants, as well as expertise in developing chemical process models.

In 2021, she and her co-authors were awarded the Junior Moulton Medal by the Institute of Chemical Engineers (IChemE) for their research on CO2 capture technology development. Since completing her PhD in early 2016, Mai has published 21 journal papers, several technical reports, book chapters and two edited books on Carbon Capture and Storage and Greenhouse Gas Removal Technologies. She also works as a consultant, providing her expertise on clean energy and carbon management solutions to clients in the private and public sectors.

Mr. Todd Flach, Bellona NGO

Todd is a Senior Advisor for CCS (CO2 Capture and storage) in The Bellona Foundation in Oslo, Norway. He has been working on a range of challenges spanning technology, safety, security, advocacy, public acceptance, project management, and more within CCS since 2003.  This includes projects and clients for a variety of projects located on almost every continent. Prior to that, he worked as a specialist in reservoir technology in the oil and gas industry. Todd holds a Master's degree in engineering from The University of Texas (Austin).

Dr. Florian Kraxner, IIASA

Florian Kraxner is a principal research scholar with the Biodiversity and Natural Resources Program at the International Institute for Applied Systems Analysis (IIASA) and holds a visiting professorship on land-based negative emission technologies at Korea University in Seoul.

At IIASA, he is leading research on Agriculture, Forestry, and Ecosystem Services (AFE) where he puts emphasis on integrated global landscape modeling complemented with renewable energy systems optimization and impact assessments of climate change, with a particular interest in natural disturbances. His research portfolio includes forest and landscape restoration, nature-based and natural climate solutions. Biodiversity, sustainability, and a strong link into societal topics are cross-cutting themes throughout his work.

Florian holds a PhD in Environmental Sciences from Hokkaido University Sapporo in Japan and has served as the president of the International Boreal Forest Research Association (IBFRA) since 2018.
