What They Do

STX Group focuses on trading over 50 environmentally related commodities, including renewable energy certificates, biofuels, renewable natural gas (RNG), and carbon offsets. Instead of direct technology development in solar energy, wind, storage, or hydrogen, the company offers comprehensive services through its STRIVE by STX division, such as procurement strategies for Energy Attribute Certificates (EACs) and energy efficiency consulting. Their target markets include sectors such as the automotive industry, manufacturing, maritime sector, and utilities, aiming to reduce CO2 emissions through tailored decarbonization solutions (source: stxgroup.com). With 25 years of trading experience and a strong position as a market maker, STX Group has traded over 410 TWh of EACs in FY25, underscoring their expertise in the sector.

Projects & Track Record

Although STX Group primarily trades in commodities and provides procurement services, their track record includes facilitating massive volumes, such as over 410 TWh of EACs in FY25. Their role focuses on supporting markets for renewable natural gas in sectors that are hard to decarbonize, such as industrial production and the maritime sector. The company has not documented specific completed projects, as their focus is on trading and consulting rather than project ownership. Their ongoing efforts include integrated pathways for corporates, including the execution of VPPAs and the procurement of RNG (source: stxgroup.com).

Recent Developments

In the past two years, STX Group launched STRIVE by STX on April 20, 2023, integrating their climate consulting and renewable energy procurement services. On December 5, 2023, they introduced a working capital SPV for environmental certificates, enabling higher upfront payments and balance sheet-friendly financing for ESG compliance. The relocation of the headquarters on February 28, 2024, to the CROSSOVER building marked a significant growth milestone, as they serve over 7,000 customers (source: stxgroup.com).

Working at STX Group

STX Group employs nearly 600 professionals in various roles, including trading, risk management, and consulting through STRIVE. Most hiring occurs at their headquarters in Amsterdam, with opportunities in their 10 global offices. The company culture emphasizes employee well-being in sustainable spaces, such as their WELL Silver-certified headquarters, and supports a dynamic growth trajectory with over 25 years of market experience. While specific benefits are not publicly documented, the headquarters offers energy-efficient facilities and smart mobility to enhance workplace efficiency (source: stxgroup.com).
