The Alliance published a Project Preparation Glossary that complements the Harmonized PPF Application, Green City Finance Directory, and Alliance knowledge products on project preparation. After identifying a need for common definitions of project preparation terms used by the Alliance,  the Secretariat developed definitions through consultation with the Project Preparation Action Group, the ICLEI Climate Finance Glossary, and the CPI Global Landscape of Climate Finance Methodology. The glossary has been adopted by the Sustainable Infrastructure Foundation’s SOURCE platform.
