G&A Institute has analyzed index companies’ sustainability reporting activities since 2011. Our research over the past seven years shows that corporate reporting on sustainability -- including environmental, social and governance (ESG) performance and achievements -- continues to be a consistent, reliable standard for the largest and most influential companies in the US capital markets. “Sustainability reporting” rose dramatically from 2011, when roughly 20% of companies published reports, to 72% just three years later in 2013. From 2013 to 2017, the frequency of reporting has increased each year, now up to 85% of companies reporting in 2017.
