Conclusions and Recommendations

Abstract

This chapter presents the principal conclusions and recommendations of this assessment of the technical capabilities for supporting a multipollutant, risk and accountability-based management strategy for North America. The conclusions and recommendations are presented in two parts: the first part addresses multipollutant and risk-based air quality management, and the second part addresses accountability. The conclusions and recommendations reference the levels of transition to a full risk- and results-based air quality management approach outlined in Chap. 2, and they incorporate the principal conclusions and recommendations from Chaps. 3 through 12. Although the conclusions and recommendations are discussed separately owing to their focus, they are in fact interrelated. Resolution of uncertainties and gaps in the tools and information needed to support risk assessment, assessment of exposure and system response, evaluation of the impact of climate or technological change, implementation of supporting measurement programs, and demonstrations of accountability will be required before a comprehensive multipollutant, risk-based, and results-based air quality management can be realized.
