Which includes the carbon dioxide and carbon monoxide in the atmosphere produced by business processes and systems?
Carbon emissions include the carbon dioxide and carbon monoxide in the atmosphere, produced by business processes and systems.
How is carbon monoxide produced quizlet?
formed by the incomplete combustion of the fossil fuels and wood. Gas, oil, coal, wood in boilers, oil burners, gas fires, water heaters, solid fuel appliances, and open fires.
Where does the carbon from carbon Capture go?
CCS involves the capture of carbon dioxide (CO2) emissions from industrial processes, such as steel and cement production, or from the burning of fossil fuels in power generation. This carbon is then transported from where it was produced, via ship or in a pipeline, and stored deep underground in geological formations.
What are the three business functions an MIS infrastructure supports?
MIS infrastructure is made up of 3 primary areas supporting operations, change and the environment.
