To bring about change, you must explain it and, above all, prove it. That is the goal of sustainable communication. Behaviours change when the message is clear, and a dialogue begins. All stakeholders must be involved to shape a society with a sustainable economy, energy, and philosophy. Sustain is part of this dynamic: going even further and creating communication that is at the crossroads of businesses’ corporate communication, the investigative work of journalists, and the involvement of NGOs.
