    Accelerating the Transition to a Low-Carbon Economy

    STX Group helps accelerate the transition to a low-carbon economy by connecting capital to climate action. Through trading, innovation and market insights, we make environmental progress possible.

    Our Vision

    A global economy where every commodity reflects its environmental impact.

    We envision a world where environmental progress is accelerated through market forces. A world where emissions have a price and positive contribution has tangible value.

    We navigate complex global regulations to help companies and institutions meet their climate goals. By channeling capital into high-impact projects, we ensure that sustainability initiatives are not just imagined but realized at scale and in time.

    We are not just traders. We are traders of environmental progress. We are STX.

    Our Mission

    We build trust in environmental markets through market-based solutions to accelerate global decarbonization.

    We build trust and drive efficiency in environmental markets by bringing liquidity, price transparency and execution certainty to every trade.

    At STX, we connect supply with demand across global compliance and voluntary markets, from renewable energy and carbon to low-carbon fuels and energy efficiency. We enable capital to flow where it drives the greatest environmental impact, helping accelerate the low-carbon transition at scale.

    As traders of environmental progress, we don’t just respond to market needs, we anticipate them. We price risk, unlock value and shape emerging markets with the rigor, discipline and agility of a trading house. Our mission is clear: to make sustainability investable, tradable and real.
