This document summarizes Armida Andres' presentation on estimating finance needs and developing effective biodiversity finance plans from a Philippine perspective. It discusses how the BIOFIN methodology was used to cost the actions in the Philippine Biodiversity Strategy and Action Plan (PBSAP) over 2013-2028. This facilitated analysis to better implement the PBSAP and inform conservation policies, financing, and investment choices. The costing helped secure $10 million for the government's coastal program in 2018. The process involved stakeholders and produced messaging targeting various sectors. The iterative costing of the PBSAP through BIOFIN emerged as a best practice for transformation.
