CARBON: A LONG-TERM CONTRIBUTION REQUIREMENT

On Coal is the largest CO2 emitter, yet it is still the main source of energy in the world and his request remains, especially in Asia.

Global demand for coal has risen again since 2017, after two years of decline, to 5,357 Mtec (million tonnes of coal equivalent), according to figures from the International Energy Agency (AIE).

Asia, and in particular China is the largest consumer.

Coal is mainly used for electricity generation. Coal factories remain the largest source of electricity generation in the world (40%, before gas).

China's coal plants have increased production since 2017, but their appetite could fall under pressure from policies that seek to improve air quality in Chinese cities, the IEA said.

India can take China's position as the world's largest coal consumer. Other countries also experienced strong growth in their consumption, including Indonesia, Malaysia, Pakistan, the Philippines, and Vietnam.

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

In the long run, the IEA expects the requirement to stagnate around 5,400 million tonnes by 2040. The decline in demand from China, the European Union and the United States would be compensated by the increase in India and the Southeast Asian

Coal plays an important role in greenhouse gas emissions.

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

Given the risks to the climate, the IEA believes it "urgent action is needed" to support carbon capture and storage (CAC).

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

There are only two large collection and storage centers for coal: Petra Nova in Texas and the dam at the border in Canada. A large project in Mississippi, USA, was abandoned.

The CO2 capture capacity is only 2.4 million tonnes per year. It will have to reach 350 million tons in 2030 to comply with the Paris Climate Agreements, according to the IEA.
