He has undertaken military tours, led extreme and high-risk expeditions all over the world and run multi-million dollar business units.
“The importance, scale and sensitivities around the establishment and scaling of carbon removal, makes pluralistic participation and co-development of the sector a fundamental cultural requirement which the Centre will seek to advocate.”


Stephen Hall
Co-Founder and Non-Executive Director
Steve is a University Academic Fellow at the School of Earth and Environment, University of Leeds. His specialisms include low carbon transitions business models and finance. He is interested in the links between low carbon innovation, economics, energy, climate change and society.
Steve has undertaken international work on urban emissions modelling, infrastructure finance and energy decarbonisation. Steve has recently published research on innovative business models for energy transitions, how finance and ownership models have both technical and social effects on energy systems.
“Developing the right policy, economics, and public dialogue around carbon removal is vital for the expansion of the sector, it is just as important as advancing tech. I hope the Carbon removal centre can play its part in speeding up that development”

“Neil deGrasse Tyson once said of the Apollo spaceflight program: ‘”… audacious visions have the power to alter mind-states—to change assumptions of what is possible. When a nation permits itself to dream big, those dreams pervade its citizens’ ambitions.’ — I can’t help but agree.
