Established in 2007, Sustainable Development Capital LLP (SDCL) is a leading investment firm specializing in clean energy, energy efficiency, and decentralized energy infrastructure projects. The firm is headquartered in London, United Kingdom, and operates internationally with offices in New York, Hong Kong, Dublin, and Singapore.

SDCL's investment strategy centers on developing and investing in sustainable energy infrastructure assets that reduce costs, lower carbon emissions, and enhance reliability. The firm deploys a wide range of commercially proven technologies, such as on-site renewables like solar paired with storage, renewable heat, cogeneration, and energy conservation measures including LED lighting, energy-efficient heating and cooling, motors, and building management systems.

In November 2025, SDCL expanded its capabilities by acquiring Volery Capital, a U.S.-based private equity firm focused on the energy transition. This acquisition created a comprehensive platform for sustainable investment capital, combining SDCL's real assets expertise with Volery's private equity investment capabilities. The combined firm manages over $2 billion in assets across more than 50 investments worldwide, reinforcing SDCL's position as a leader in funding and operating energy efficiency and decentralized energy generation projects.
