As the number of researchers interested in the relationship between entrepreneurship and sustainable development continues to grow, a window of opportunity exists to create a vibrant research community to advance a deeper understanding of the nature, promise and limitations of sustainability entrepreneurship. This special issue aims to communicate developments fromThe First World Symposium on Sustainable Entrepreneurship, Leeds, UK, July 2007, to a wider research community and to reflect the discussions during the symposium. The articles in this special issue demonstrate that there is real value in recognising that sustainability entrepreneurship is distinct from other forms of entrepreneurship and that these distinctions should not be dismissed as trivial.
