The Ranking of Responsible Companies is a recognised list of Poland’s largest companies assessed for applying the necessary instruments to improve policies, structures and processes in order to more fully meet the challenges of sustainable development. Subsequent editions of the Ranking are a continuation of its first version published in Manager Magazin in 2007 and 2008 under the name “Good Company Ranking”, in 2009 in Gazeta Prawna, and from 2010 in Dziennik Gazeta Prawna. All editions were prepared by Prof. Bolesław Rok and Jarosław Horodecki. The survey on which the Ranking is based is modified every year to take into account changes on the Polish market. The ranking is based on the results presented by the companies themselves in the survey and verified according to a proprietary methodology.
