The creative sector has played a significant role in efforts to raise awareness of the impacts of climate change and encourage sustainable social, economic, and environmental practices worldwide. Many artists and cultural organizations have embarked on remarkable projects that make us reflect on our behaviors, our carbon footprints, and the claims of infinite growth based on finite resources. Sometimes treading a fine line between arts and advocacy, they have sparked extraordinary collaborations that reveal new ways of living together on a shared planet. The 'art of the possible' will become even more relevant as 2016 dawns - bringing the challenge of how to implement the Sustainable Development Goals and the Climate Change Agreement adopted at the end of 2015. Yet with negotiations overshadowed by scientific controversy, political polemic and geographic polarization, individuals can easily lose faith in their own ability to shape change beyond the hyperlocal level. Against this challenging backdrop, could the arts and creative practice become a particle accelerator - to shift mindsets, embrace new ways of sharing space and resources, and catalyze more creative leadership in the public and private spheres? The goal of this Salzburg Global Seminar session was to build on path-breaking cultural initiatives to advance international and cross-sectoral links between existing arts and sustainability activities around the world, encourage bolder awareness-raising efforts, and recommend strategic approaches for making innovative grassroots to scale for greater, longer-term impact.
