Our Team

Who we are

We are a non-profit organisation, and are a group of passionate, visionary professionals united in our belief in the imperative of urgent action to remove carbon dioxide from the atmosphere to help prevent dangerous warming. We believe in the power of technology to supercharge the solutions already found in nature, and we look forward to collaborating with people who share our vision and commitment to a different world.

Stig Arff

Stig Arff


Stig has a PhD in physics from the University of Oslo combined with an MBA from the Norwegian School of Management (BI). For the past two decades Stig has worked within the finance sector, and has established several successful business ventures. His early career years were within research and industry and he first became aware of the problem of climate change when he was studying physics in the early 1980s. He is struck that the changes to our climate are following a trajectory which to a large degree was predictable even then. Whilst our knowledge of the science and the solutions has increased by orders of magnitude, and the public and politicians are increasingly aware of the problem, not enough has been done to tackle it. Stig created CTRF to pursue brilliant scientific ideas that increase the chances of preserving a livable planet.
