About Us


Who we are

The CTRF Board is comprised of core strategic funders, committed to CTRF’s mission and purpose, as well as experts from other fields, who can bring diverse knowledge and expertise to guide CTRF’s strategic direction and hold the organisation accountable.

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.
