E2430 V1 Environmental Impact Assessment Public Disclosure Authorized (EIA) Of the Yemen Power Sector Project (IDA Financed) Public Disclosure Authorized For the Yemen Electricity Distribution Loss Reduction Carbon Finance Project Public Disclosure Authorized Public Disclosure Authorized Carbon Finance project: Yemen Electricity Distribution Loss Reduction (P110603) ------- Linkage to Yemen Power Sector Project (P086865) This cover page serves to clarify the linkage between the Yemen Electricity Distribution Loss Reduction Carbon Finance Project and IDA financed Yemen Power Sector Project. The Yemen Electricity Distribution Loss Reduction CF project aims to purchase the emission reductions created by the implementation of the substation upgrading and distribution investment in demarked areas in 18 regions of Yemen under the Power Sector Project. The carbon finance operation does not involve any modification of the existing Project or any additional activities out of the scope of the original Project, although the implementation schedule in the Project Design Documents reflects the updated project progress. The idea of a potential carbon finance operation was extensively discussed and agreed with the borrower during project preparation, though the potential CF operation was not explicitly described in the PAD. The inclusion of the CF operation in the PAD would not have affected any aspect of the project design and preparation. The Power Sector Project was prepared and appraised in accordance with Bank policies and procedures, including Bank’s safeguards procedures and policies. These procedures and policies meet the full requirement of the CF operation. Prior to the signing of the Emission Reduction Purchase Agreement (ERPA), the Environmental Impact Assessment and Resettlement Policy Framework prepared under the Power Sector Project, which apply equally well to the Yemen Electricity Distribution Loss reduction CF Project, are being disclosed again as per the requirement of a carbon finance operation.
