This report contains the main results of the Third FAO Regional Workshop on statistics for greenhouse gas emissions which was held in Casablanca, Morocco, 02-03 December 2013. Key issues highlighted for progress included reliability, sustainability and comprehensiveness of data collection and analysis procedures. Countries identified the need for improved institutional arrangements as the most crucial and critical, underpinned by the need to provide human, technical and financial resources for development, implementation and maintenance of sound GHG inventories. A key role for FAO was identified and recommended, in order to ensure sustainable assistance to its Member Countries, to facilitate dissemination of technical material, and to further develop its capacity development activities based on country needs and in collaboration with relevant agencies.
