GreenArc Impact Reporting
Our impact measurement and reporting system has been developed using GIIN’s IRIS indicators informed by the framework
guidelines of the Impact Management Project (IMP). We are a member of the IMP’s Impact Frontiers cohort, a
practitioner community of impact investors innovating best-in-class impact measurement and monitoring (IMM) systems.
More details on Impact Frontiers can be found here.
A set of specific and relevant social indicators are mapped to each lender and loan, taking into account factors such
as number and size of loans, end beneficiary, SDG contribution, gender equality and access to basic services.
Performance data is collected against each metric, and the portfolio is allocated a score based on its alignment with
how we assess expected impact, comparability relative to national socio-economic benchmarks where appropriate, and
contribution to social & environmental objectives.
GreenArc Impact Score
An impact score provides a framework for comparison and consistency for decision making. It helps investors
understand where and how impact is created, as well as to prioritise investments based on expected impact.
GreenArc’s impact scorecard is calculated according to the 5 dimensions of impact as per IMP consensus, reflecting a weighted sum of indicators that collectively cover the multiple aspects of impact.
Overall, the scorecard has approximately 10-15 indicators across 5 broad categories, the scores of which are added
together with a maximum score potential of 10 (highest impact).
