This winter huge areas of northern China have been smothered by smog. As many as 460 million people, equivalent to the combined populations of the US, Canada and Mexico, have choked under a thick blanket of noxious air that has pushed the air pollution index to record-breaking levels.
One in seven premature deaths in Chinese citizens is caused by air pollution. Each “airpocalypse” sees thousands of people admitted to hospitals, many for respiratory diseases. The culprits are well-known – heavy industry like steel and cement and, most of all, coal-fired power.
The severity of the air pollution problem has prompted China to take action at home by reducing coal usage and reining in approvals for new coal-fired power plants. But across the rest of Asia, countries continue to invest in coal-fired power. Much of this funding is from Chinese companies.
Chinese investors are backing nearly 80 coal-fired power plants worldwide, typically in countries with much weaker emission controls than China. The country is not alone; Japanese and Korean institutions are also committing billions of dollars for coal power and banks in both Asia and the West are ignoring their environmental and social guidelines to finance coal projects.
Air pollution from coal-fired power plants in Southeast Asia is already responsible for 20,000 premature deaths a year. If planned coal projects go ahead that figure could rise to 70,000 from illnesses such as lung cancer, strokes and respiratory disease, according to new research from Harvard University and Greenpeace International.
That would mean a death toll from coal plants alone approaching the toll of the catastrophic Indonesian forest fires in 2015. And it would happen every year.
About 9,000 of these excess deaths in 2030 are in China. This means even as Chinese emissions from coal decline in the coming decades, transboundary pollution from rising coal emissions in Southeast Asia may become an increasing issue.
Health costs of coal
The team of researchers mapped out current emissions from all coal-fired plants in the region and projected emissions to model how much air pollution levels would increase in future, then assessed the health impacts.
In some of those countries, particularly Indonesia and Thailand, there is growing electricity demand and coal is viewed as the easiest and cheapest way to meet it. But this requires governments to ignore the broader costs to people’s health and the environment. In Indonesia, the estimated health costs of existing planned projects could easily swamp the country’s annual health budget.
The figures should make sober reading for any government and compel them to review their plans. If all proposed coal-fired power projects go ahead, emissions from coal will triple by 2030. The World Bank president has said such an expansion would be “a disaster” for our planet because of the impact on climate change.
It’s also not the case that the death toll would be offset somehow through development benefits. Coal does not lift people out of poverty, as a report from 12 leading aid agencies recently confirmed. In fact, it does exactly the opposite. Governments should not use poverty-reduction to justify coal projects that would condemn millions to a life of poor health.
Transboundary pollution will hit China
At a time when major industrialised countries are switching to clean, renewable energy and turning their backs on coal, countries and regions across Asia seem stuck in the last century. China has been the world’s coal behemoth for the past decade but is now the only country taking serious steps to reduce its coal dependence and build a clean energy future – driven, in part, by the huge cost of air pollution.
Such pollution ignores international frontiers. While domestic emissions are responsible for most coal-related deaths, by financing coal projects in neighbouring countries, China will continue to suffer as many as 9,000 premature deaths a year in 2030 resulting from transboundary air pollution from neighbouring countries and regions.
Governments and businesses across Asia seem in thrall to coal. Investment decisions being made today will cause harm for decades to come. This winter’s airpocalypse across northern China is a warning of what that harm could look like.
