This report summarises an assessment of a range of leading metrics that can be used to credibly measure and report on performance over time and across multiple spatial scales. The research focuses on six critical sustainability issues: deforestation, biodiversity, water use, forced labour, poverty, and Greenhouse Gas emissions.

The Wage Auditing Working Group sought to explore this potential by providing opportunities for sustainability systems to discuss the topic of wages, including auditing and verification of wages, to support their efforts to measure and bridge living wage gaps. The working group ran from May 2021 to June 2022. It was set up as part of a 1.5-year project led by ISEAL on supporting effective measurement, verification and improvement of living wage gaps.
