The People\u2019s Republic of China is still the world\u2019s biggest single source of environmental harm. China overfishes the world\u2019s oceans<\/a>, blasts mercury<\/a> and nitrous oxide<\/a> and other pollutants into the atmosphere, and dumps plastic waste<\/a> into the sea. It has made progress on many of these problems, but when you\u2019re the biggest global manufacturer, it\u2019s very hard not to also be the biggest global polluter. <\/p>\n

China\u2019s most devastating environmental impact has been its emissions of greenhouse gases. Thanks to its unprecedented use of coal, China releases more carbon every year than the United States and Europe combined:<\/p>\n

\"\"<\/a><\/p>\n

And yes, this is true even after you account for offshoring<\/a> of emissions. China is also the world\u2019s leading emitter of other greenhouse gases \u2014 methane<\/a>, nitrous oxide, F-gases<\/a>, and so on. Historically, China has only accounted for 15%<\/a> of total carbon emissions, but its share is rising quickly. <\/p>\n

Unless China decarbonizes, there can be no victory<\/a> over climate change, and the planet will roast. This is not a moral statement, but a simple fact. <\/p>\n

There are two ways to decarbonize: 1) degrowth, and 2) green energy. None of the proponents of degrowth are asking China to stop growing its economy, and it wouldn\u2019t matter if they did; China has no intention of slowing its growth in order to save the rest of the planet from climate change. <\/p>\n

In fact, the same is true of the developing world. India, Southeast Asia, Africa, the Middle East, and Latin America aren\u2019t going to impoverish themselves in order to save the climate. The only way for these countries to grow their economies without roasting the planet is to replace coal and oil with solar and batteries \u2014 or to grow rich using solar and batteries in the first place, skipping the fossil fuel stage entirely. <\/p>\n

The only way this is ever going to happen is if solar power and batteries (and other green technologies) are really, really cheap. China, India, and the rest will not adopt these technologies because Greta Thunberg tells them to. They will only switch to green energy if it\u2019s cheaper to do so. <\/p>\n

So if we want to save the world from climate change, the only really effective way to do this is to make green energy as cheap as possible. <\/p>\n

How do we make green energy cheap? In the past, this meant doing a bunch of scientific research, in order to drive breakthroughs in our understanding of solar and batteries. But although that research continues, and is still important, there has been a major shift; now, cost decreases come mostly from scaling effects. This is from an MIT News report<\/a> on a paper by Kavlak et al.<\/a> in 2018:<\/p>\n

The relative importance of the factors [driving down solar costs] has changed over time, the study shows. In earlier years, research and development was the dominant cost-reducing high-level mechanism, through improvements to the devices themselves and to manufacturing methods. For about the last decade, however, the largest single high-level factor in the continuing cost decline has been economies of scale, as solar-cell and module manufacturing plants have become ever larger.<\/p>\n

You can visualize this cost decline with a scaling curve, which shows how costs go down as the volume produced goes up:<\/p>\n

Similar curves exist for batteries<\/a>. These are all specific instances of something called Wright\u2019s Law<\/a>, which says that the more you build of something, the cheaper it gets. Not every physical technology follows Wright\u2019s Law, but solar, batteries, and many other green technologies do follow it. <\/p>\n

This is why for many years, I wrote that the best way<\/a> for the U.S. to defeat climate change was to scale up the production of solar power, batteries, and other green technologies. The Inflation Reduction Act, with its subsidies for green energy and electric vehicles, was a victory for my desired approach. <\/p>\n

Except that victory was far too modest and short-lived. The IRA was good<\/a>, but it wasn\u2019t transformational on a global scale. And because the Republican Party has made opposition to green energy a pillar of their ideology, the Trump administration and the GOP Congress are now canceling and obstructing<\/a> solar plants and battery factories, even though that will make energy more expensive for Americans. <\/p>\n

America has abdicated the fight against climate change.<\/p>\n

But that doesn\u2019t mean the strategy I advocated for defeating climate change was a bad idea. In fact, it\u2019s still going to work! It just won\u2019t be America that executes that strategy. It will be China. In fact, it already is. <\/p>\n

China has long subsidized the production<\/a> of solar cells and wind turbines. In recent years it has also lavished enormous subsidies<\/a> on the electric vehicle industry:<\/p>\n

Xi Jinping has emphasized electric vehicles, batteries, and renewable energy as the \u201cnew three\u201d<\/a> \u2014 the core of the \u201cnew productive forces\u201d reshaping global technology and power. Whether or not he\u2019s right about that (and I think he is), his focus on green technology suggests that although some subsidies have been pulled back<\/a>, China will continue to focus on promoting these technologies. <\/p>\n

In addition to these subsidies, China has applied its typical strengths \u2014 cheap bank loans, integrated supply chains, copious engineering talent, and wage suppression \u2014 to the scaling of green tech manufacturing. As a result, China now dominates global solar panel production:<\/p>\n

And China now accounts for over 70%<\/a> of all the electric car production on the planet, and production is still soaring:<\/p>\n

China is achieving similar dominance<\/a> in wind turbines, industrial electrification technology, heat pumps (to a lesser extent), and so on. <\/p>\n

All of this green technology production is helping to finally curb China\u2019s apocalyptically high emissions levels \u2014 just as advocates of green growth have always predicted it would. Green energy is starting to displace coal in China in both electricity production and industrial heating, leading to a plateau and even a small reduction in Chinese emissions over the last year or two:<\/p>\n

This trend needs to accelerate a lot, but China is still scaling up green technologies, so I\u2019m pretty hopeful that it will. In the meantime, just making Chinese emissions plateau is an incredibly impressive accomplishment.<\/p>\n

But in fact, China is doing a whole lot more than just curbing its own emissions \u2014 it\u2019s helping the developing world to grow without ever emitting a lot of carbon in the first place. China is exporting huge amounts of green technology to developing countries:<\/p>\n

Most of these panels are going to Africa, the Middle East, and Pakistan:<\/p>\n

China\u2019s exports of EVs are also soaring:<\/p>\n

An increasing number of these are going to developing countries<\/a> as well, as the U.S. and EU erect trade barriers against Chinese EVs. <\/p>\n

Again, it\u2019s crucial to remember that developing countries are buying all this green tech not because of morality, or even because of self-preservation (since whether they decarbonize or not has very little effect on global emissions). They\u2019re buying all this green tech because it\u2019s cheaper than fossil fuel tech. <\/p>\n

China is what made green energy cheap. Yes, part of this is subsidies. But a lot of it is just good old scaling laws \u2014 China produces in such vast quantities that costs keep getting driven down and down<\/a> across the board. The scaling laws still work, and China is the undisputed master of physical scaling. <\/p>\n

What this means is that China is executing the strategy I\u2019ve long advocated for saving the world from climate change. While U.S. energy policy dithers and shoots itself in the foot over ridiculous culture wars, China\u2019s dogged industrial policy and peerless manufacturing prowess has made green energy so cheap that simple economics are going to take over from here. <\/p>\n

I\u2019m generally known as a harsh critic of the Chinese government, and of Xi Jinping\u2019s leadership<\/a> in particular. But in this case, I think we have to give credit where credit is due. The United States \u2014 the country that defeated the Axis, fed the world with the Green Revolution<\/a>, and did so much to promote global growth and technological progress over the last century \u2014 has utterly dropped the ball on the biggest environmental challenge of our age. Instead, the threat will be met and defeated by China, and \u2014 more than any other single individual \u2014 by Xi Jinping himself. That\u2019s no small accomplishment.<\/p>\n

China\u2019s success in battling climate change should also provide various doomers and pessimists with a reason for hope. It\u2019s easy to fall into the trap of thinking of all the world\u2019s problems as aspects of a single \u201cpolycrisis<\/a>\u201d. But the truth is that problems often don\u2019t reinforce each other; sometimes, they cancel each other out. The Second China Shock<\/a> \u2014 the wave of heavily subsidized manufactured exports that is now threatening to deindustrialize many countries around the world \u2014 is certainly a threat to many nations\u2019 domestic industries. But at the same time, that wave of exports is doing a huge amount to help fight climate change. <\/p>\n

Personally speaking, I wish America had been the country to save the world from climate change. I wish democracy had proven more effective than autocracy at meeting a global environmental threat. But at this point I\u2019ll take what I can get. <\/p>\n
