Industrial

The industrial sector directly accounts for nearly 20 percent of total U.S. greenhouse gas emissions – these come from both energy (on-site combustion) and non-energy (industrial processes) sources. When greenhouse gas emissions from electricity use are distributed among end-use sectors, the industrial sector accounts for about 30 percent of total U.S. emissions. Industrial processes that produce greenhouse gas emissions vary significantly and include such diverse sources as iron and steel production, cement production, and the petrochemicals industry.
