Electricity and heat production are the largest contributors to global emissions. This is followed by transport, manufacturing, construction (largely cement and similar materials), and agriculture. But this is not the same everywhere. If we look at the United States, for example, transport is a much larger contributor than the global average.
Coal; It is used in electricity production, heating, iron-steel and cement industry and other fields of industry. Coal ranked second after oil with a share of 26,9% in world primary energy consumption in 2021. In the world electricity production, it ranked first with a share of 35,9%.
Cement acts as the binder between aggregates (fine and coarse rocks) in the formation of concrete. While cement makes up only a small percentage of the mix (approximately 12 percent by volume), it is almost exclusively responsible for the resulting CO 2 emissions. In the cement-manufacturing process, raw materials are heated to high …

Coal consumption for thermal power, iron/steel and cement production. We state that 'at least 25% of coal is used for other activities than power, iron/steel and cement production'.
Concrete is among the world's most consumed materials—second only to water. 1 That's because its durability, affordability, and availability make it essential to countless construction projects, from bridges, to roads, to buildings. Since concrete is used on such a large scale, it also produces large amounts of heat-trapping greenhouse …
