The Green Accelerator (GA) is a Hong Kong–hosted, philanthropy-funded nonprofit platform that prepares scalable, bankable green projects in emerging markets and developing economies (EMDEs). It launched in 2026 at the Hong Kong Green Finance Association Annual Forum, with backing referenced in the Hong Kong SAR Government’s 2026–27 Budget. GA is built around the climate-finance “bankability gap”: many technically viable green projects in the Global South never reach financial close because they lack project preparation, proven operating models, and documentation that meet the investment criteria of multilateral development banks, sovereign wealth funds, and international commercial banks. The platform uses philanthropic capital for design, preparation, technical assistance, and capacity building so proven technologies can be assembled into investable portfolios. Work is organized across energy transition, sustainable food systems, circular economy, and water and climate resilience. A Steering Committee of founding members sets strategy; a secretariat and regional teams run day-to-day operations. Founding members named at launch include the Asian Infrastructure Investment Bank, the Cambridge Institute for Sustainability Leadership, the HKSAR Environmental Protection Department, GenZero, the Institute of Finance and Sustainability, the Silk Road Fund, and HSBC. The initiative is hosted by Sprinkles (HK) Charity Foundation, a Section 88 tax-exempt charity registered in Hong Kong, with listed office locations in Hong Kong, London, and Singapore.

Founded in October 2021 as the BC Centre for Innovation and Clean Energy (CICE), it launched with $105 million in commitments from the Government of British Columbia, Shell Canada, and the Government of Canada through Natural Resources Canada’s Energy Innovation Program. NorthX is based at Suite 1210, 1066 West Hastings Street in Vancouver and is led by President and CEO Sarah Goodman.
