Summary
Ethylene ranks among the top-20 chemicals, with nearly 200 million metric tons made globally in 2020. Its production requires much energy that is currently derived from fossil fuels. This chapter discusses environmental impacts for ethylene production from petroleum, natural gas and biomass sources, predicted using commercial software. Most of the predicted environmental impacts are within the same order of magnitude. For all feedstocks, the main sources of adverse environmental impacts are greenhouse gas emissions, acidification and air pollution stemming from the burning of fossil-based fuel; and for agricultural operations, production of fertilizers and pesticides needed for cultivation (in the case of ethanol), ocean-based transportation of crude oil and the chemical processing steps (for all feedstocks). An assessment of the environmental impacts of different fossil energy sources (coal, natural gas and fuel oil) reveals almost similar carbon footprints to produce a given quantity of energy. The predicted emissions agree well with the actual emissions data reported by coal-based and natural gas-based power plants to the U.S. Environmental Protection Agency (USEPA).
