The report suggests was to improve biogas data collection, including reducing survey costs, improving response rates, simplifying the data collected and using local knowledge about previous projects and programmes.

This report explains how IRENA approached the challenges of data collection to produce the estimates of off-grid energy production and use. An overview of the data collected and detailed tables are provided.

This field guide presents various methodologies for estimating biogas capacity, production and consumption. Such information can be integrated into national censuses, household surveys and energy surveys.

This publication presents a structured methodology that countries can use to assess their capacity to produce renewable energy statistics.
