Sustainability is simultaneously the fundamental and a secondary challenge for societies. It is a fundamental challenge defining the operating space for humanity, but as a long-term, wide-spanning, and holistic issue, it is often overlooked by actors focusing on narrowly defined and short-term economic or social concerns. The main aim of sustainability communication is to create bridges between these co-existing realms of long-term and immediate challenges. This paper discusses the use of sustainability strategies and indicators as tools to encourage a wide variety of actors, including private enterprises, to take concrete actions that produce systemic changes towards sustainability. Experiences from the ongoing national-level sustainable development commitment process of Finland are presented, and lessons for Latin America are identified. A key lesson is the importance of transparency in sustainability communication.
