# IESR: Mandatory B50 Requires Careful Economic Review Supply and Emissions - IESR

> Indonesia's IESR think tank called for careful economic review of the mandatory B50 biodiesel policy, citing fiscal and supply impacts. It estimates B50 could raise CPO demand by about 4 million tonnes per year, which would cut exports, and warns that export levy revenue funding the biodiesel subsidy could fall.
