The document outlines an Electrabel campaign called "Together for less CO2" aimed at improving the company's image and promoting its new green energy product called Green+. The campaign goals were to increase perceptions that Electrabel cares about the environment and build trust in the brand through sustainability engagements, as well as make Green+ the number one green energy supplier. The campaign involved demonstrating Electrabel's environmental commitments through advertising, appealing to customers emotionally to participate, and promoting the Green+ offer and tangible results. The campaign was a success, exceeding its new Green+ client goal and increasing customer trust in the brand. However, the document notes the positive impact eroded quickly when communication stopped, so continued sustainability communication efforts would be needed
