Some people define green jobs as those whose aim is to reuse, repurpose, and/or recycle. Others insist that, to be considered green, jobs must provide decent wages and job security. Still others maintain that green jobs must be part of carefully designed environments where workers use nontoxic, safe-to-handle materials to create products that are beneficial for consumers and the environment. The NIOSH Prevention through Design (PtD) initiative puts this last definition into practice. Since 2007, PtD has promoted ways to eliminate hazards and minimize risks through the design of safe workplaces. Recently, PtD methods have been adopted to make green jobs safe for workers and the environment. These projects are examples of ways to address occupational health and safety (OHS) challenges in the coming green economy-an economy based on an environmentally stable and socially just marketplace.
