A consistent approach to impact measurement allows sector stakeholders to comprehensively estimate impact, helping to streamline reporting, attract investment and drive regulatory support. For this reason, the GOGLA Impact Working Group has used the best available research to develop a set of metrics that companies and investors can use to estimate the impact of their businesses or investments.
Updated in September 2018, the metric framework covers a range of off-grid solar technology sizes, from solar lanterns to large solar home systems, as well as seven thematic areas: energy access, economic activity, income generation, kerosene use and CO2e reduction, light availability and quality, energy spending and financial inclusion. The GOGLA standardized metrics also form part of the official IRIS catalogue, an initiative of the Global Impact Investing Network (GIIN).
GOGLA would like to thank the UK Department for International Development for its support for this revision of the standardized impact metrics.
