What Sustainable Development Capital does

Sustainable Development Capital (SDCL) is a London-based specialist investment firm founded in 2007 by Jonathan Maxwell, operating as a Limited Liability Partnership authorised and regulated by the UK Financial Conduct Authority. SDCL develops, invests in, and manages funds focused on energy efficiency and decentralised energy infrastructure, deploying commercially proven technologies including combined heat and power, solar PV, heat pumps, battery storage, LED lighting, building management systems, and energy conservation measures through an energy-as-a-service model that requires no upfront capital from end users. Named off-takers include Citigroup, Santander, NHS hospitals, Tesco, ArcelorMittal, US Steel, Rolls Royce, Panasonic, and AstraZeneca, spanning financial services, healthcare, retail, heavy industry, and manufacturing.

The firm runs a multi-fund platform comprising the Global Energy Transition Fund (GETF, €650M) targeting late-stage development and construction opportunities in Europe and North America, the London EDGE Fund (£100M) co-invested with the Greater London Authority for London-wide decarbonisation, SEIT as a London Stock Exchange-listed investment trust, and private equity capabilities acquired through the November 2023 purchase of Volery Capital. Combined AUM exceeds US$2 billion across more than 50 investments. SDCL monetises through management fees on AUM, carried interest and performance fees on fund investments, direct project cashflows from long-term service agreements, and private equity returns from the Volery platform. Distribution is conducted via direct relationships with institutional investors (pension funds, sovereign wealth funds, family offices) and corporate clients, supported by offices in London, New York, Dublin, Hong Kong, and Singapore.

Strategic activity through 2024-2026 has emphasised diversification into new verticals and geographies. The June 2024 minority investment by General Atlantic's BeyondNetZero fund brought institutional climate capital and a board seat. Subsequent moves include the €100M investment in Germany's Empact for real estate decarbonisation (October 2025), a €100M partnership with Carbon AMS to finance a biomethane facility in Ireland using Siemens / rhobot.ai edge-native AI (November 2025), a strategic collaboration with FuelCell Energy for up to 450MW of data-centre fuel cell deployment targeting AI workloads (January 2026), and a preferred-supplier appointment with East Lothian Council for hyperscale data-centre development (October 2025).
