Yet for many African government, addressing air pollution is not a pressing concern. According to present knowledge, one in eight of today’s global deaths is a result of exposure to air pollution - either (outdoor) ambient air pollution (AAP) or (indoor) household air pollution (WHO (2014a, 2014b), jointly causing around 7 million deaths per year. The estimated economic cost of these deaths is greater than that caused by unsafe sanitation or underweight children. Over 45,000 African children under the age of 5 die annually due to air pollution (2012), which is one of the highest regional child mortality rates in the world. Estimates of the economic cost to Africa of indoor and outdoor air pollution approach $250 billion annually (Roy, 2016). The growing rural-urban migration and increase in population being experienced in Ghana, is likely to outpace and challenge the already inadequate infrastructure that exists to manage pollution. The cities of Accra and Tema host most of the country’s industries, some of which are aged and high emitting. The vehicle fleet of Ghana is also increasing, with the current population of registered vehicles as of February 2017 standing at approximately 2.1 million (DVLA data). The Greater Accra Metropolitan area (GAMA) has the highest number of registered vehicles of about 1.2 million (59% of the national fleet). These activities, including settlement issues, if not addressed holistically could pose serious risk to ambient air quality and public health in the Greater Accra Region In the Greater Accra Region, EPA Ghana estimates that in 2015, 2,800 lives were lost due to the effects of air pollution. This number is projected to increase to approximately 4,600 by 2030 if no action is taken to reduce current and projected future levels of air pollution. Implementing this air quality management plan, can reduce that number by 430 each year. Additional negative health outcomes associated with air pollution, such as asthma cases and missed school and work days, can be reduced as well. EPA Ghana developed this comprehensive Air Quality Management Plan (AQMP) for the GAMA and Greater Accra Region as the next step in addressing these problems. This plan complements the National Development Planning Commission that seeks to encourage the Local Government to take up the developmental challenges of their jurisdiction and improve the lives of citizens. Key features of this plan include: Baseline air quality characterization and projected emission trends Health burden estimates Source-specific and ambient air quality standards Air quality monitoring network Detailed implementation plan EPA Ghana expects to update this plan again in five
