Dot range chart comparing U.S. and global GHG emissions by industrial sector, showing that iron and steel, cement, and petrochemical production produces the most emissions globally. In the United States alone, cement production produces the most emissions.
Notes: “Industry” includes all manufacturing activities, petroleum refining, and construction. It does not include extraction of raw materials (e.g., mining, drilling, and forestry), agriculture, waste management (e.g., water treatment and landfills), or fugitive emissions. It also does not include emissions from transporting input materials or output products, as those are part of the “transportation” sector. Percentages may not add up to 100 percent due to independent rounding.
