The story comes from last year's campaign from the oil industry (which works under the UP, Union Petrolière, name) that had a slogan that said "Heating with fuel: for a better climate protection". Greenpeace said at that time "The UP has used inappropriately the concept of climate protection and it's ridiculous that private companies might rule our environmental policies, because protecting our climate means stop using oil."
For its part, the UP said that the advertising campaign was focused on their improvement in the quality of fuels which meant they were safer for the environment. They can't say so in Switzerland, though.
