2005 – Founding of STX

STX was founded in Amsterdam, historically a meaningful starting place for global trade. We found ourselves as pioneers in our nascent industry. We traveled Europe by car and by train, buying and selling carbon credits to match supply and demand, making this new marketplace work as we grew our business bottom up.

We started our international team on a canal house in the beautiful city centre, dealing and dialing across the globe from the beginning. We realized then that environmental markets would become mainstream, and our pioneer role in building our business in these markets may well have contributed to the integrity of these markets today.

Today – At forefront of global change

We are at the forefront of global change. A change away from pollution and from depletion of natural resources. We have been pricing the cost of emissions and pollution for over fifteen years and have helped build trust in carbon and in new markets for other products.

We see our market thesis confirmed, as we are witnessing a societal tipping point, at times very fast yet often still slow, but surely from few scientists sending out warnings to a global, collective feeling of need for change, for action. Our business is to support companies that act, and we do so around the world. We see the EU and national governments everywhere are putting in place sticks and carrots to further kickstart markets for pricing and trading the cost of pollution. And what started with compliance markets for carbon certificates has sparked a move to unprecedented corporate action on voluntary basis far beyond carbon alone – leading to new marketplaces to be served.

As STX, we have become a specialist in trading environmental commodities. We do not create wind farms, solar parks, or execute large energy reduction projects. But we are a market maker in environmental commodity markets, and our everyday work contributes to the reliability and the professionalism of these markets*, which in turn increases confidence in such sustainable investments.

*We are aware that objections to market makers in environmental commodities may arise in the same way that they periodically come up around market makers in listed markets (equities, derivatives, bonds) – but we believe increased market efficiency overall lowers transaction costs and improves the very functioning of markets

Vision 2050 – Full transparency on the contribution or pollution value of any company, product and service

We see that pollution has a price and that positive contribution has a value. Our vision is that these two components will be included on every company’s P&L and in the price of every product and service. Not only will this ‘true pricing’ accelerate the green energy transition, and ensure all kinds of transportation, whether marine, road or aviation, to be powered by renewable energy in the best and most efficient way. It will also create a massive global market for (the price of) pollution and (the value of) positive contribution. We see these components will be traded around the world as a commodity, like raw materials.


We believe that the markets of the price of pollution or the value of positive contribution will move towards full transparency, which will push global action for the better. And we believe that in this process, a commercial opportunity lies in making these contributions tradable in a marketplace – before global corporate action to have become mainstream and our markets have become commodity markets like any other.


We accept as a society we cannot abandon all forms of pollution at once. However, in 2050, through the mechanism of tradable environmental commodities, consumption will be smarter, pollution will less and the world will be more sustainable. And STX will be a trusted, admired market maker with a presence across all tradable environmental commodity markets.
