Global warming is one of the major challenges of the 21th century. The reduction of the greenhouse gases is therefore of special interest. Companies have to face several challenges if they want to measure and reduce greenhouse gases. Two studies have asked the question how companies evaluate the efforts for a green supply chain. These surveys were conducted by the management and technology consultancy BearingPoint. A change in mindset of executives can be revealed by comparing the corresponding results of both studies. This article highlights the position for green logistics of more than 600 companies in the 2010-2011 survey. The results are compared with the former study of 2008. An evolution over the past years becomes visible: from awareness to implementation actions.
