What is theRaf foundation?
The Refreeze the Arctic Foundation (RAF) is a not-for-profit charity with a single goal: fast
track research into MCB.
Located in The Netherlands, the RAF has the "ANBI" status, ensuring its independence from
sponsors and transparency in fund deployment. Under certain circumstances, the "ANBI" status
also provides tax advantages to sponsors.
Less than 10% of contributions are used for running the RAF, the rest goes to research.

Our "ANBI" status ensures independence from sponsors & transparency in fund deployment
90%
RAF is mostly run by volunteers who keep the organization small. This allows RAF to allocate 90% of donations to MCB research
RAF’s slogan is:
Meet ourdirectors
The RAF Directors combine 50 years’ experience across chemical engineering, biotechnology, accounting, and patent rights. They pool knowledge, expertise and above all passion to help tackle the greatest challenge of all times: roll back global warming.

Jan Van Breugel
Science & Technology advisor
“Humanity will not willingly change its ‘spending attitude’ nor restrict its exponential growth and therefore we need to create a safety net”

Frans Vendeloo
Director
“Buying time is one thing, but let’s not waste it: CO2 reduction is the only solution”

Barbara Veldhuis
Director
“MCB will help make the future brighter and keep the planet cooler. However, MCB will only work if we reduce pollution and respect the world around us by changing our daily habits and behaviours.”

From thestart
The RAF was established with a donation by the late Hanns Walter Salzer Levi (the HWSL donation).
Hanns, an accomplished businessman, was also a remarkable polyglot and an amateur historian. Known for his curiosity, generosity, and empathy, Hanns had the ability to charm everyone he met with his modesty, wit, and vast knowledge. In the autumn of his life, he became much concerned with climate change. Hanns passed away on 21/10/21, aged 96. He never reached winter.

How does the RAFoperate?
RAF brings together world-class research institutes in the field of MCB. RAF has already created a core consortium between the Centre for Climate Repair at Cambridge (CCR) and the Technical University of Delft Climate Institute (TUDCI). The consortium intends to reach out to other institutes and make research results publicly available, on a non-profit basis.
