In 2008, California enacted laws to restructure chemical policy and promote green chemistry. Ten years after the passage of California’s green chemistry laws, we assessed their performance through structured interviews with a sample of experts from government, academia, business, and the nonprofit sector. We combined the interviews with a scoping literature review to propose a new ten-point framework for evaluating the effectiveness of a chemical regulatory policy, and we assessed the performance of the California law against this framework. The California program performed well on transparency of the regulatory process; protecting vulnerable populations; placing the primary burden on the manufacturer; breadth of regulatory authority; and advancing the public right-to-know. Areas of weakness include unclear authority to require data on chemical use in products; an inefficient pace of implementation; and limited incentives for innovation. Promoting safer chemicals in products will require additional incentives to protect public health and the environment.
