A talk given by Carlos Martinez to the Young Communist League’s Harry Pollitt School, on China’s international strategy on climate and the environment.
Carlos looks at what’s actually happening on the ground: China’s solar capacity has overtaken coal for the first time, its carbon emissions have been flat or falling for nearly two years, and it’s now exporting that green transition to the Global South – financing solar and wind projects across Africa, helping Cuba keep the lights on through a brutal US blockade, and making clean energy cheap enough for the rest of the world to actually use. The talk sets this against the record of the imperialist powers, and makes the case that China’s record isn’t an accident, but the product of a planned, socialist economy.
Transcript
Comrades, thank you very much for inviting me, and thanks to the Young Communist League for organising this year’s Harry Pollitt School – and for supporting the Socialist China Conference last weekend.
I’ve been asked to talk about China’s international strategy in relation to the environment.
Starts at home
China’s international role rests on what it has done at home, so let me start there briefly.
For years we were told that China was the world’s greatest climate villain – the biggest emitter of greenhouse gases; building coal plants left, right and centre.
It’s true, China is overall the world’s biggest emitter of greenhouse gases – albeit it’s a very large country with a population of 1.4 billion people, and a manufacturing powerhouse that engages in a great deal of industry, and its per capita emissions are half those of the United States or Canada.
It’s also true that China still burns more than half the world’s coal.
But there is an unmistakeable direction of travel. In July, China’s installed solar capacity overtook coal for the first time, reaching 1,286 gigawatts – around ten times Britain’s entire generating capacity from all sources. Coal has gone from around 80 percent of China’s energy mix a few decades ago to under 50 percent today, and this number continues to fall. Where new coal stations are built, these are typically to provide backup capacity for intermittent renewable sources, which means they’re playing an important role in the energy transition. In 2025, China added more solar than the rest of the world combined.
China’s carbon emissions have now been flat or falling for nearly two years. And last year, for the first time, China committed to an absolute cut in emissions: 7 to 10 percent below peak by 2035.
As is well known, China is by far the world leader in electric vehicles, electric buses, high-speed rail, batteries, solar panels, wind turbines and other clean energy technologies.
None of this happened by accident. Carbon Brief recently went through the 72 thematic five-year plans published by Chinese ministries this year, and found that 54 of them – three quarters – include policies or targets related to climate change and energy. Decarbonisation in China runs through the whole system of economic planning.
That’s possible because the commanding heights of the economy are in public hands, because the major banks are state-owned, because even the private economy is regulated and incorporated into the planning system, and because economic priorities are connected to the long-term needs of society rather than the pursuit of short-term profit.
Affordable and renewable
The single biggest contribution China has made to the global fight against climate breakdown is something fairly prosaic: it has made clean energy cheap.
Over the last 15 years, the global cost of solar power has fallen by more than 80 percent, and wind by around 60 percent, almost exclusively the result of Chinese investment, innovation and scale. As Kevin Tu of Columbia University put it, “if the Chinese manufacturers had not brought down the cost of panels by more than 95 percent, we could not see so many installations across the world.”
This is a game changer for the Global South. Africa has 60 percent of the world’s best solar resources – meaning that it’s exposed to a hell of a lot of solar radiation – but until recently it was too expensive to leverage that. Now it isn’t.
Africa’s solar installations rose by 54 percent last year. And when the criminal US–Israeli war on Iran sent oil and gas prices through the roof this spring, countries across Asia and Africa responded by buying Chinese solar.
In March, according to Ember Energy, Chinese solar exports hit an all-time record of 68 gigawatts, equivalent to Spain’s entire solar capacity. Exports to Africa nearly tripled in a single month, and Nigeria, Ethiopia and Kenya each imported more than a gigawatt for the first time.
So every target in China’s five-year plan is also manifested in the green transition in the Global South.
Global cooperation
In 2021, Xi Jinping announced at the UN General Assembly that China would build no new coal-fired power plants abroad. Today, 59 percent of China’s energy projects in Africa are solar and wind.
Chinese companies have built the Benban solar park in Egypt, wind farms in Ethiopia and South Africa, hydroelectric stations in Zambia, and a battery-backed solar plant is going into every one of Zambia’s 156 constituencies.
And this is not about creating a relationship of dependency. China is helping countries in the Global South to build their own renewable energy industries. For example, when Zimbabwe decided to stop exporting raw lithium, a Chinese company committed 400 million dollars to building a processing plant there.
The most moving and most poignant example is Cuba. Facing a barbaric – let’s say it, genocidal – energy siege imposed by the Trump regime, with the national grid collapsing again and again, and tens of thousands of patients waiting for operations, China has helped Cuba install around 900 megawatts of solar power. At the Socialist China conference last Saturday, First Secretary at the Cuban Embassy Pablo Ginarte told us this had taken the renewable share of Cuba’s electricity from around 3 percent to 21 percent in a single year. As he put it: “The United States cannot blockade the sun”.
Bizarrely, there are some in the West, and in the Western left, who see all this progress and call it “green imperialism”. These modern-day Lenins have come up with a new definition of imperialism that doesn’t include domination or coercion; where a country can become an imperialist power without wars, coups, military bases, destabilisation campaigns, unilateral sanctions, economic coercion, unequal exchange or structural adjustment. Apparently China has become imperialist through building solar farms in Zambia. Either this is a stunning and important theoretical development, or it’s utter nonsense; I’ll leave it to you to decide.
Defending multilateralism
China has also been the most consistent defender of the international framework for tackling climate change. It insists on the Paris Agreement, and on the principle of common but differentiated responsibilities – the idea that the rich countries, which caused the problem, should take the lead in cutting emissions and should provide technology and financial resources for sustainable development in the Global South.
Although, as an aside, in reality it’s China that’s doing the lion’s share of this work!
Meanwhile, Trump has pulled out of the Paris Agreement for a second time, called climate change “the greatest con job ever perpetrated on the world”, and made “drill, baby, drill” the official energy policy of the most powerful country on Earth.
Not to mention waging war on Iran and supporting a genocide in Gaza, both of which are having devastating environmental consequences.
Meanwhile, Washington and Brussels slap tariffs on Chinese solar panels, batteries and electric vehicles – the very things the world needs most – and accuse China of “overcapacity” for making too many of them.
Why this matters
What does all this mean for us in Britain?
First, it means that the New Cold War is not only a threat to peace; it’s a threat to the planet. Every tariff on Chinese solar panels and every attempt to cut China out of supply chains makes the green transition slower and more expensive, in Britain as much as anywhere. A Britain that cooperated with China on renewable energy, on electric transport, on grid technology, would be doing far better on its climate commitments, and furthermore would bring down energy bills.
Second, it’s a reminder that socialism works. The West has had more than 30 years of climate summits, and we’ve been told the whole time that the market will sort it out, or that we can save the planet if only we take shorter showers and make sure we put our packaging in the right bin. China has shown that a green transition happens when a socialist state plans for it, invests in it and puts the long-term needs of humanity ahead of short-term profit.
And third, many people who care about the environment are starting to look at China with fresh eyes, and to ask why it is succeeding where our own rulers are failing. As young communists, you are well placed to help them find the answer.
Xi Jinping said last year that “however the world may change, China will not slow down its climate actions, will not reduce its support for international cooperation, and will not cease its efforts to build a community with a shared future for mankind.”
Let’s do what we can to support that, and to build a world where cooperation, not coercion, is the guiding principle of international relations.
Thank you.
