The Coal is the largest emitter of CO2, but it is still the main source of energy in the world and its demand remains, especially in Asia.

Global demand for coal has increased since 2017, after two years of decline, to 5,357 Mtek (millions of tonnes of coal equivalent), according to figures of the International Energy Agency (AIE).

Asia, and especially China is the largest consumer.

Coal is mostly used to generate electricity. Coal plants remain the largest source of electrical production in the world (40%, before gas).

Chinese coal plants have increased production since 2017, but their appetite could undergo pressure from policies seeking to improve air quality in Chinese cities, the IEA notes.

India could snatch China's position as the largest coal consumer in the world. Other countries also registered a strong increase in their consumption, including Indonesia, Malaysia, Pakistan, Philippines and Vietnam.

"Many developing countries consider that coal is important for its economic development due to its availability and its relatively low cost", explains the international agency.

In the long term, the IEA expects the demand to reach around 5,400 million tons by 2040. The fall requirement of China, the European Union and the United States would be compensated by the rise in Asia and Southeast Asia

Coal carries an important role in greenhouse gas emissions.

He responded to 40% of CO2 emissions in 2017, before oil (34%) and gas (19%), according to the Global Carbon Project Association.

Given the risks to the climate, the IEA believes that "urgent action needs" to maintain carbon capture and storage (CAC).

But this technology, which consists of catching the CO2, which leaves the chimneys to store them in the soil, is very expensive.

There are only two large carpets and storage centers: Petra Nova in Texas and Boundary Dam in Canada. A large project in Mississippi (United States) was abandoned.

Captured capabilities count only 2.4 million tons every year. It will have to reach 350 million tons in 2030 to respect the Parisian Climate Agreements, according to the IEA.
