Y Coal is the biggest emitter of CO2, but it's still the main source of energy in the world and its call continues, especially in Asia.

Global demand for coal increased from 2017, after two years of decline, to 5,357 Mtec (millions of tonnes of equivalent coal), according to figures of the International Energy Agency (ESA).

Asia, and in particular China is the largest user.

Coal is mainly used to generate electricity. Coal plants are the largest source of generating electricity in the world (40%, before gas).

Chinese coal plants have increased production since 2017, but the desire could be under pressure from policies that seek to improve air quality in Chinese cities, IEA notes.

India could capture China's position as the largest coal consumer in the world. Other countries also recorded strong growth in their use, including Indonesia, Malaysia, Pakistan, Philippines and Vietnam.

"Many developing countries consider coal is important for its economic development because it is available and a relatively low cost", explains the international agency.

In the long run, the IEA expects the demand to estimate about 5,400 million tonnes by 2040. The decline in demand from China, the European Union and the US is offset by the rise in India and the Southeast Asia

Glass plays an important role in greenhouse gas emissions.

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

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

But this technology, which includes collecting CO2 that leaves chimneys to store in the soil, is very expensive.

Only two large coal mining and storage centers are: Petra Nova in Texas and Boundary Dam in Canada. A big project in Mississippi (US) was left.

Capturing CO2 equates to just 2.4 million tonnes a year. He will have to reach 350 million tonnes in 2030 to respect the Paris Treaty on climate, according to the IEA.
