China’s war on pollution could leave Australia’s dirty coal out in the cold Updated for 2026





China’s recent move to limit imports of the dirtiest coal from 2015 onwards is a scary prospect for Australian miners.

The proposed restrictions will ban the burning of coal with high levels of ash or sulphur in areas around major cities, as the Beijing government battles its pollution crisis.

Analysts say that as much as half of the thermal coal currently shipped from Australia to China could run afoul of the new measures.

The exact effects on Australia’s coal export market are hard to predict, and will doubtless vary between different companies and coalmining regions.

But what is clear is that unless it can find some new customers, the sector is likely to find itself in trouble.

Aussie coal – a mainstay of the economy

Australia is the world’s fourth-largest coal nation, with a A$16.9 billion industry that produces 401 million tonnes a year – almost 8.9% of the world total.

Industry groups have claimed that coal mining contributes some A$60 billion a year to Australia’s economy – roughly the same as the iron ore and agricultural sectors – while supplying A$3 billion in total yearly royalties to the Queensland, New South Wales and Victorian state governments.

Like other resource exports, Australia’s thermal coal sales – worth A$16 billion worldwide according to the Bureau of Resource and Energy Economics – are at the mercy of the world market.

The Australian coal industry is already reeling after two years dogged by job losses, increased costs and rapidly eroding profitability. Nearly 10,000 coal workers lost their jobs in 2013, and more lay-offs are expected in the future.

Coal prices are tumbling

With coal prices already falling, Australian exporters could also face the extra prospect of having to ‘wash’ their product to bring ash and sulphur within China’s new guidelines – which will add costs and damage profit margins. The potential extra cost has been estimated at anywhere between A$1 and A$27 per tonne.

Since 2004 there has been a continuous slowdown in mining sector productivity (the output relative to capital and / or labour input), mainly because both labour and capital costs have been consistently above the global average.

Yet despite these productivity issues, and the growing worldwide expectation that coal mining and coal-fired power generation should meet higher environmental standards, the Australian coal sector is focusing on increasing its production.

Recently, despite contention about the environmental impacts, federal environment minister Greg Hunt and the Queensland government approved the Carmichael coalmine in the Galilee Basin.

One of the largest coal projects in the world, the new mine will cover 200 square km and add up to 60 million tonnes annually to Australia’s existing coal production. In an increasingly competitive market, Australia will need to find more buyers for its new coal supplies.

Does Australia need more coal? Or more customers?

Indonesia already competes with Australia to export to China, and it is anticipated that the United States will increase its coal exports from the Powder River Basin in Wyoming and Montana over the next few years.

Meanwhile, other emerging producers including Mongolia and Mozambique are expected to create significant competitive pressure in the world’s coal export market.

At the same time, many Asian economies are increasing their electricity generation capacity – some of it through renewable energy including hydro, solar and wind power.

But all is not yet lost – significant amounts of new fossil fuel generation is also likely to come on stream, which may open new avenues for Australian coal exports.

China has recently shown interest in investing in coal-fired power plants in Pakistan – and Pakistani power minister Khawaja Muhammad Asif said earlier this month that one of the sources of coal could be Australia.

What will China’s new rules mean?

It is not yet clear how much Australia’s coal industry stands to lose from China’s new rules. The costs of processing it to the required standard are not clear, particularly because much of Australia’s coal is well above the Chinese requirements anyway.

But the move nevertheless represents another new problem for a sector that is facing many other challenges – including deterioration in terms of trade (the ratio of export prices to import prices), low coal prices, exchange rate appreciation, declining productivity, and the emergence of overseas rivals with lower production costs.

That is why Australia’s coal sector is now focusing on ramping up production, to try and gain a competitive advantage over emerging Asian and African miners and capture a greater market share for sustained export earnings.

The climate challenge

The other major challenge facing Australian coal, highlighted by this week’s UN Climate Summit in New York, is fact that much of the world is aiming to wean itself off it.

China’s thermal coal use is forecast to peak in just two years, and UN climate chief Christiana Figueres has advocated the replacement of fossil fuels with alternative energy sources.

China’s investment in up to 200 gigawatts of wind energy is just one sign that it is aiming to reduce its dependence on coal. There is a growing sense that China is getting serious about cutting its greenhouse emissions.

China’s new coal regulations are a warning to Australian miners that they won’t survive either without exploring other export markets besides their traditional customers, China and Japan.

And if Australia wants to remain an energy exporter far into the future, it should focus on exploiting its admirable technological abilities to develop renewable energy products that could diversify its exports still further.

The UN saved the ozone layer – now it’s the climate’s turn Updated for 2026





It sometimes feels as if environmental news is never good news, but that certainly isn’t true when it comes to the ozone layer. The UN has announced that the ozone layer is showing signs of recovery.

Evidence has pointed to recovery for some time, but researchers have waited until they were confident that the hole in the ozone layer was beginning to heal. It’s not yet restored to perfect health – that will take a few more decades – but a significant corner has been turned.

That good news comes 30 years after governments around the world began to sign up to the Vienna Convention for the Protection of the Ozone Layer.

Solving global environmental problems takes time, but the success of the Vienna convention, and the Montreal Protocol that puts the convention in to action, is proof that when the world works together, and keeps working together even when the going gets tough, it can deliver the solutions that we all need.

Of course, having written “that we all need” begs an important question. Why does the ozone hole matter to me?

We have all seen those NASA images of the ozone hole over the Antarctic, but that’s a long way from where most of the planet’s population lives. It’s a little like that scene at the end of ‘Happy Feet’ where the politicians challenged to respond to the plight of the penguins ask why they should “worry about a load of flightless birds”.

So why should we worry whether or not there is a little more or less ozone, a tiny fraction of the gases in the atmosphere, than there might have been if we hadn’t all changed our fridges and under-arm deodorants?

What’s the ozone layer ever done for us?

The most obvious answer is that the ozone layer protects us from ultraviolet (UV) light, and that being exposed to too much UV can eventually cause skin cancers. OK, but just how many skin cancers have been prevented by protecting the ozone layer?

Until recently, it has been hard to answer that with any sort of numbers, but research has begun to model what the world would have been like if we had not protected the Earth’s ozone layer.

These ‘world avoided’ models are indicating that without the Montreal Protocol people around the world would already be exposed to increases in UV. Those increases would be enough to be causing skin damage that, over time, would mean more people developing skin cancers.

In fact, the most recent estimate of what would have happened without ozone protection suggests that by 2030 there would have been around 2 million more cases of skin cancer a year worldwide.

That can’t be a precise figure, but even if we take as a ‘ball-park’ estimate, that’s 2 million people every year being saved from skin cancer because governments acted to protect the ozone layer.

Looking over a longer timescale, do the maths. Two million fewer skin cancers a year, year on year on year soon generates some very large numbers. And those figures don’t take in to account the massive ozone depletion that would have occurred worldwide by the middle of this century.

Can we do it again, with climate?

That collapse in global ozone is a consistent outcome of ‘world-avoided’ research and would have increased UV levels around the world beyond anything that has ever been experienced since humans evolved.

Maybe we could have coped with that, but it would have been difficult. Yes, we can all reduce our exposure to UV by how we choose to behave, that’s probably the biggest factor affecting our risk of skin cancer in the world we actually live in. But what about in the world avoided?

How much sun-cream would you have needed if without protection you would begin to sunburn in just a few minutes? What clothes would you send your children to school in? Health-warning signs on the beaches?

And even if you could cope, what about the damage to crops, to forests and to the oceans that would have resulted from run-away increases in UV, the scale of which we can’t yet really quantify.

So yes, the news that the ozone layer is beginning to recover is a good reason to be cheerful. Be cheerful because we have protected the planet. Be cheerful because we have protected human health.

Above all, perhaps, be cheerful because the success of the Vienna Convention and the Montreal Protocol shows that global governments can work together to solve major environmental problems.

When the Vienna Convention was signed no one could be really sure exactly how ozone depletion might develop, but governments were brave enough to make tough decisions based on the best estimates of future risks. 30 years later, research allows us to confirm just how right those decisions were.

Surely that’s good news not just for ozone, but also as we look ahead to the even tougher challenges of responding to climate change.

 


 

Nigel Paul is co-chair of the United Nations Environment Programme (UNEP) panel on ozone depletion and Professor of Plant Science at Lancaster University, but he writes here in his personal capacity. During the 1990s he received funding for research in to the effects of ozone depletion from UK research councils and the EU.

These ‘world avoided’ models are indicating that without the Montreal Protocol people around the world would already be exposed to increases in UV. Those increases would be enough to be causing skin damage that, over time, would mean more people developing skin cancers.

In fact, the most recent estimate of what would have happened without ozone protection suggests that by 2030 there would have been around 2 million more cases of skin cancer a year worldwide.

That can’t be a precise figure, but even if we take as a ‘ball-park’ estimate, that’s 2 million people every year being saved from skin cancer because governments acted to protect the ozone layer.

Looking over a longer timescale, do the maths. Two million fewer skin cancers a year, year on year on year soon generates some very large numbers. And those figures don’t take in to account the massive ozone depletion that would have occurred worldwide by the middle of this century.

Can we do it again, with climate?

That collapse in global ozone is a consistent outcome of ‘world-avoided’ research and would have increased UV levels around the world beyond anything that has ever been experienced since humans evolved.

Maybe we could have coped with that, but it would have been difficult. Yes, we can all reduce our exposure to UV by how we choose to behave, that’s probably the biggest factor affecting our risk of skin cancer in the world we actually live in. But what about in the world avoided?

How much sun-cream would you have needed if without protection you would begin to sunburn in just a few minutes? What clothes would you send your children to school in? Health-warning signs on the beaches?

And even if you could cope, what about the damage to crops, to forests and to the oceans that would have resulted from run-away increases in UV, the scale of which we can’t yet really quantify.

So yes, the news that the ozone layer is beginning to recover is a good reason to be cheerful. Be cheerful because we have protected the planet. Be cheerful because we have protected human health.

Above all, perhaps, be cheerful because the success of the Vienna Convention and the Montreal Protocol shows that global governments can work together to solve major environmental problems.

When the Vienna Convention was signed no one could be really sure exactly how ozone depletion might develop, but governments were brave enough to make tough decisions based on the best estimates of future risks. 30 years later, research allows us to confirm just how right those decisions were.

Surely that’s good news not just for ozone, but also as we look ahead to the even tougher challenges of responding to climate change.

The UN saved the ozone layer – now it’s the climate’s turn Updated for 2026





It sometimes feels as if environmental news is never good news, but that certainly isn’t true when it comes to the ozone layer. The UN has announced that the ozone layer is showing signs of recovery.

Evidence has pointed to recovery for some time, but researchers have waited until they were confident that the hole in the ozone layer was beginning to heal. It’s not yet restored to perfect health – that will take a few more decades – but a significant corner has been turned.

That good news comes 30 years after governments around the world began to sign up to the Vienna Convention for the Protection of the Ozone Layer.

Solving global environmental problems takes time, but the success of the Vienna convention, and the Montreal Protocol that puts the convention in to action, is proof that when the world works together, and keeps working together even when the going gets tough, it can deliver the solutions that we all need.

Of course, having written “that we all need” begs an important question. Why does the ozone hole matter to me?

We have all seen those NASA images of the ozone hole over the Antarctic, but that’s a long way from where most of the planet’s population lives. It’s a little like that scene at the end of ‘Happy Feet’ where the politicians challenged to respond to the plight of the penguins ask why they should “worry about a load of flightless birds”.

So why should we worry whether or not there is a little more or less ozone, a tiny fraction of the gases in the atmosphere, than there might have been if we hadn’t all changed our fridges and under-arm deodorants?

What’s the ozone layer ever done for us?
