With the presentation of the thermometers to E.ON and Eneco, respectively the dirtiest and cleanest power companies in the Netherlands, Greenpeace is seeking to call attention to power companies’ plans for the construction of new coal power plants in the Netherlands. Greenpeace’s action is based on the findings of research into the sustainability of Dutch power companies conducted by SOMO.

How does E.ON compare to other power companies? Greenpeace gave SOMO the task of researching Dutch power companies' performance on sustainability issues. Greenpeace then summarised the results of SOMO's research into the Ranking. The Ranking clearly shows that E.ON is the dirtiest power company in the Netherlands. As a result of this dubious honour, Greenpeace is presenting E.ON with a two meter-high red thermometer today.
