The environmental factor would be impacted the most by requirements for a project to implement an air quality control system at a coal plant. This is because coal combustion produces various air pollutants, such as particulate matter (PM), sulfur dioxide (SO2), nitrogen oxides (NOx), carbon dioxide (CO2), and mercury, that can harm human health and the environment12. An air quality control system can reduce the emissions of these pollutants by using different technologies, such as low NOx burners, flue gas desulfurization, electrostatic precipitators, and carbon capture and storage23. However, these technologies also have environmental impacts, such as water consumption, waste generation, energy consumption, and greenhouse gas emissions4. Therefore, the project manager should consider the environmental factor in terms of the project scope, objectives, constraints, risks, and stakeholders, and evaluate the trade-offs and benefits of different air quality control options5.
