Neste Oyj is a Finnish refining and marketing company headquartered in Espoo, renowned as the world's leading producer of sustainable aviation fuel and renewable diesel. It refines waste, residues, and other renewable raw materials—such as used cooking oils, animal fats, and vegetable oil residues—into high-quality renewable fuels and feedstock for polymers and chemicals at refineries in Finland, the Netherlands, Singapore, and through a joint venture in the United States. With an annual nameplate capacity of approximately 5.5 million tons for renewable products, Neste plans to expand to 6.8 million tons by 2027, including transformations at its Porvoo and Rotterdam sites. The company operates nearly 1,000 service stations across Finland and the Baltic states, supports customers in reducing greenhouse gas emissions by up to 20 million tons of CO2e annually by 2030, and maintains a strong commitment to safety and sustainability. Founded in 1948 to secure Finland's oil supply, Neste has evolved from a traditional oil refiner into a global leader in renewable and circular economy solutions, employing around 5,800 people worldwide.
