Many organizations have been making a commitment to adopt environmental practices as part of sustainability efforts in their organizations. However, some of these organizations are finding that it is more difficult to improve environmental performance than they initially thought. We propose that entrepreneurial behavior can help to explain the variance in the progress of environmental practice adoption in organizations. Specifically, we examine the ability to recognize opportunities and enact resources, two key aspects of entrepreneurship, and their role in creating unique solutions to improving environmental performance. We measure entrepreneurial bricolage, the process of making do with the resources at hand, to understand how organizations create new opportunities for implementing environmental practices.
