A SCIENTIFIC WAY OF IMPROVING THE WORLD
We make conversion capacity assessments based on SCIENCE. The questions When, Where and How are answered through independent assessment by our scientific partners. Given that this metric uses a combination of satellite data and advanced algorithms linked to the largest physical global data base of terrestrial carbon sinks, our information is undoubtedly UP TO DATE AND ACCURATE. Moreover, we get the added perspective of an independent physical audit as executed by third-party inspectors to verify our data.
PEER-REVIEWED SCIENTIFIC METHODS
For measurement of real scientifically verified carbon sequestration, using latest global satellite data and AI-based algorithms.
INDEPENDENT AUDITORS & SCIENTIFIC ASSESSORS
Global Science Network including members contributing to the UN’s IPCC Report, which also includes NASA, ESA, Jet Propulsion Lab, ETHZ, GOOGLE and others.
THE CARBON SINK MODEL
Only terrestrial carbon sinks regularly convert CO2 into Oxygen. But the exact amounts vary quite substantially from location to location owing to various factors/reasons.
We plan on bridging this disparity. That is to say, to make reality a reliable statement on the conversion capacity of any given stretch of land or sea, we are working together with the scientific community and several world class research institutions.
Our lead scientific partner is the Crowther Lab Research Group. Building on peer reviewed research, they have developed the “Carbon Sink Model” which provides data on the carbon storage capacity for every square kilometer of every terrestrial location on Earth. With a knowledge base that involves research collaborations with the world’s leading research institutions, such as NASA’s Jet Propulsion Laboratory, NASA’s Goddard Space Flight Centre, the Max Planck Society and the UN’s Food and Agriculture Organization behind the Carbon Sink Model, its accuracy and efficiency is indisputable.

our values
IT’S GOOD FOR COMPANIES, IT’S GOOD FOR NATURE, IT’S GOOD FOR OUR CHILDREN
COMPLETE TRANSPARENCY
We are the first completely transparent, trackable and immutable way to offset GHG emissions through scientifically verified sequestration, using blockchain technology.
This means the connection between an Emitter and a Convertor becomes visible and therefore both parties know exactly with whom, for what, and for how much, they are entering a transaction with. We believe that transparency and traceability are crucial to move our economy towards a more sustainable future.
POSITIVE SYNERGIES
We are a platform that offers opportunities and positive synergies for corporate ESG criteria, millennium SDGs and positive Climate Goals to be met through new perspectives and business models. We believe that business models of the future can be truly sustainable (social, environmental, economic) by providing corporate and social entrepreneurs of tomorrow with the necessary tools today.
CREATE NEW VALUE
The quantification of CO2 absorption allows custodians of natural carbon sinks to finally be remunerated in a fair manner and empowered to further invest in their CO2 absorption capacities, resulting in the protection and enhancement of forests, wetlands, protected terrestrial and marine areas, and other carbon sinks. The value of that service is bound to increase, due to the massive lack of capacity today. This automatically leads to an increased valuation of such investments and creates sustainable financial incentives on a global level.
ACTIVE RESPONSIBILITY
The planet is our foundation of life, and offers a unique and valuable service to us: the conversion and absorption of CO2 and other GHG, through which Oxygen is produced. As inhabitants of the planet Earth, we have a great responsibility to value and preserve this service and our planet for our children and all future generations to come.
our FOUNDER - Christopher’s Story
CHRISTOPHER’S STORY
I’ve often been asked why we started OXÏ-ZEN, and what led to it?
You see, I’m a full-time father of four, and in my free time, I’m an entrepreneur, aerospace engineer and professional pilot. Flying an aircraft gives you an amazing perspective on life, and time to reflect on the essence and purpose of being. It also raises doubts about one’s own actions, and where we are heading. And ultimately, how will our children tomorrow judge our actions today?
And so a few years back, we developed an innovative airline business model called AÏZEN. The point was to integrate a double CO2 offset into the operating model, meaning if we’d produce say 50 tons of CO2 on a flight between Geneva and New York, we’d offset twice that amount, i.e. 100 tons of CO2. If the offset were done using trees, we would not only be carbon negative, but our net product would be Oxygen. The idea is simple: If all businesses would strive to be carbon negative, we could by default start to reverse the disastrous slide towards global warming and climate change.
AND SO THE SLOGAN OF THE AIRLINE
WAS TO BE: FLY WITH US AND PRODUCE OXYGEN!
It was at that point we started to look into carbon certificates and carbon offsets, only to realize that there is no way we could actually claim, much less prove, that we would indeed be producing Oxygen.
To make matters worse, we found out that the current Emission Trading Schemes to a large extent have no direct effect on climate change at all. This was the moment when we realized that there was something missing. A simple and transparent system that would allow us to directly identify and engage with a Convertor of our choice, and get immutable proof of exactly how and where our CO2 was being converted into oxygen. And we immediately realized we wanted no middle men in this system, no obscure accreditations, no long stories, no paper trades, no tear-jerking NGOs, simply no zig, no zag! That led us to conceive and develop OXÏ-ZEN.
