Why is carbon dioxide now being measured in flue gases?

Measuring carbon dioxide in flue gases is important largely due to its effect on the atmosphere. Carbon dioxide is a significant greenhouse gas that contributes to climate change. By measuring CO2 emissions from combustion processes, facilities can better understand their environmental impact and take steps to reduce their carbon footprint. This monitoring aligns with global efforts to limit greenhouse gas emissions and mitigate climate change effects.

The other options touch on various aspects of combustion and emissions management, but they do not capture the overarching significance of carbon dioxide in the context of environmental and atmospheric concerns. While tuning carbon dioxide absorbers or addressing incomplete combustion are relevant to maintaining efficiency and preventing local pollution, the critical reason for measuring CO2 is its broader atmospheric implications and the role it plays in global warming and climate change initiatives. The awareness and regulation surrounding carbon emissions have become increasingly vital in policy discussions, making this measurement relevant from an environmental standpoint.
