An international colloquium, "Strategies for Clean Air and Health," was organized by the Network of Environmental Risk Assessment and Management (NERAM) and the AIRNET European Network on Air Pollution and Health to identify directions for air quality policy development and research priorities to improve public health. A conference statement was prepared to provide guidance from the perspective of an international group of scientists, regulators, industries, and interest groups on a path forward to improve the interface between science and clean air policy strategies to protect public health. The statement represents the main findings of two breakout group discussion sessions, supported by perspectives of keynote speakers from North America and Europe on science-policy integration and views of the delegates expressed in plenary discussions. NERAM undertook a carefully considered process to try to ensure that the statement would accurately reflect the conference discussions, including documentation of supporting comments from the proceedings and inviting delegates' comments on two draft versions of the statement.
