Accelerator, Grantmaker

The Adaptation Fund Climate Innovation Accelerator (AFCIA) is a programme of the Adaptation Fund, implemented by the World Food Programme (WFP) Innovation Accelerator in Munich. It identifies, supports and scales locally rooted climate-adaptation solutions that protect food systems and livelihoods in communities hit by droughts, floods, storms and rising temperatures. AFCIA runs four regional cohorts from 2024 to 2029. Each year focuses on a different region. The first cohort (2024) supported ventures implementing in Egypt, Jordan and Lebanon. The Asia-Pacific sprint (2026) includes ventures in Nepal, Pakistan and the Philippines. The third cohort targets Latin America and the Caribbean, with a live call for solutions tailored to climate-adaptation challenges in the Dominican Republic, El Salvador and Peru. The programme contributes to SDG 2 (Zero Hunger) and SDG 13 (Climate Action). It seeks both low- and high-tech innovations from established legal entities (for-profit, nonprofit, social business, NGO or INGO) that already have a presence in the country of implementation and are at least seed stage. Selected teams join a bootcamp, then can enter a nine-month Sprint with WFP support and equity-free funding. Applications for the LAC cohort close 13 September 2026, 23:59 UTC; only English submissions are accepted.

Green Accelerator

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.

Accelerator, Impact Fund

NorthX Climate Tech is an independent Canadian nonprofit investor and commercialization catalyst for climate hard tech. 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. NorthX backs physical technologies that can reduce or remove greenhouse gas emissions while producing economic benefits for British Columbia and Canada. Its focus includes energy storage and grid capacity, industrial decarbonization, clean fuels, wildfire prevention and response, carbon management, climate adaptation, and other hardware- and materials-led solutions. The organization targets the commercialization gap between technical promise and market deployment, especially projects at technology readiness levels 4–9. Funding is non-dilutive and tailored by opportunity: NorthX says investments may be repayable or non-repayable, with approved Open Intake projects receiving milestone-based reimbursement funding. Support extends beyond capital to technical validation, lifecycle assessment, investor and industry introductions, market readiness, and follow-on funding. NorthX reports that, by May 2026, it had backed more than 74 projects with over $57 million and helped catalyze more than $600 million in follow-on investment. Those figures are reported by NorthX and are not presented as independently audited outcomes. The Women in Climate Tech initiative adds a gender-lens pathway for capital-intensive climate ventures. In September 2026, NorthX reported that more than $36 million had been committed across 45 projects at companies with women in leadership—over 58% of its total capital commitments—and that those investments had unlocked more than $430 million in additional capital.
