Energy, made up of “electricity, gas, steam and air conditioning supply”, accounts for the largest portion of CO2 emissions, at about 31%, and is the top industrial (non-household) emitter. Policies that focused on electricity generation and supply, by shifting to low-carbon or zero-carbon sustainable energy sources, while costly, would be effective in curbing emissions.
Manufacturing is the second biggest source of industrial emissions, accounting for about 22% of the CO2 emitted into the atmosphere. Within manufacturing, emissions are quite split across product types (see StatLink for chart). “Rubber, plastic and other non-metal material construction” is responsible for the most manufacturing emissions at 26%. Also accounting for about a quarter of emissions in this category is “basic metal and metal product fabrications” at 23%. “Coke and refined petroleum products” make up another 16%, with “chemicals and chemical products” manufacture just behind at 15%.
Transportation comes in third for industrial carbon emissions, with the largest slice of 42% coming from land transport, including passengers and freight over road and rail, and freight through pipelines.
