Coal is the world’s largest carbon-dioxide-emitting fuel, with about three-quarters of all the energy in the world.
Coal companies are also the biggest emitters of CO2 in the United States, Canada and Australia.
Now that the power industry has been forced to shift to cleaner-burning natural gas, that power is likely to decline and coal could lose its role as the world leader in carbon emissions.
But it’s not just the coal industry that is facing the prospect of coal’s return.
The carbon-intensive extraction and refining of coal is being phased out, while other industries are shifting to cleaner energy, from solar power to wind and hydropower.
The biggest threat to coal, though, is the spread of CO 2 emissions from coal-fired power plants, which are being replaced by natural gas.
The coal industry has already seen its revenues decline by about 30 per cent since 2000.
The global coal market is expected to shrink by more than 60 per cent by 2050.
“This is a game changer, a game-changer for coal,” said Peter White, an analyst with the Carbon Tracker Initiative.
“The carbon that is being emitted is going to be much less than it was before.
The emissions from the power sector are going to drop significantly.”
In the US, coal exports to China account for more than a third of the nation’s power generation.
In China, coal accounts for just over a quarter.
“It’s an enormous market,” said Steve Mote, chief executive of the International Coal Association.
“We need to be investing in our power infrastructure and in our infrastructure to be able to keep pace with China.”
The global carbon-emissions picture is complicated by the rise of natural gas in many parts of the world, and China’s leadership in natural gas is expected not only to increase but also to accelerate.
Natural gas has been a major contributor to the carbon-free electricity sector in the US and China, and now it could be a major competitor to coal in many countries, especially in developing countries.
“As coal has become less and less competitive, we need to look at alternatives to coal,” Mote said.
“Natural gas is a different kind of fuel.
It is cleaner, cleaner, and cleaner.
It’s cleaner because it is carbon-neutral.”
China’s new leader, Xi Jinping, has vowed to reduce coal use and its use in power plants.
“China will make the transition to a clean energy economy and will continue to push the transition,” said a statement by the Chinese government, released in late September.
The world’s biggest coal producer, Australia, has also seen its coal exports decline.
In December, it announced it would phase out the export of coal from coal mines by 2020.
Australia’s energy minister, Josh Frydenberg, said that while coal was still a key source of power in the country, the country had seen a drop in the use of coal in recent years, and the coal sector was experiencing “significant growth in renewable energy.”
He said the government would review its coal policies in the next few years.
“That’s the plan.
We have to take a look at that,” Frydenburg said in an interview with the ABC.
“What we are doing right now is going about it the right way.”
As of March 31, the Australian Bureau of Statistics estimated that the coal mining industry in Australia had produced 6,500 megawatts of electricity from coal in the first half of 2018, down from more than 10,000 megawatts in the same period last year.
The mining sector is likely still responsible for about one-quarter of the country’s carbon emissions, but as the global economy has recovered, the coal companies have been forced into new, cleaner energy sources.
“There’s no question that the growth of the renewable energy sector is putting downward pressure on the coal supply,” said Mark Richardson, a senior researcher with the University of Queensland.
“So it is not only about coal.
There’s also a lot of other things that are contributing to the coal decline, including the decline in the solar market.”
For the past two years, a growing number of countries have started moving away from coal.
For example, the US has been switching to renewable energy, including wind and solar.
The European Union is also moving towards cleaner energy.
China, too, is switching away from fossil fuels.
China has seen a major slowdown in its coal production, but the country still produces more coal than any other country.
China now produces about 70 per cent of its electricity from renewable energy.
“Our energy mix is increasingly clean and renewable energy,” Chinese President Xi Jinping said in a speech last year to mark the opening of a major coal mine in eastern China.
“Coal is not the only source of electricity in China, but it is one of the biggest sources.”
China is now expected to overtake the US as the largest CO2 emitter in 2030, when the country expects
