China is the world’s largest emitter of carbon dioxide, and it has launched an enormous, multi-front campaign to bring those emissions under control. The country’s headline commitment: peak CO2 emissions before 2030 and reach carbon neutrality before 2060. Announced by President Xi Jinping at the United Nations General Assembly in September 2020, these “dual carbon” goals now drive policy across energy, transportation, industry, and land use. Here’s what that looks like in practice.
A Massive Buildout of Renewable Energy
The single most visible effort is China’s staggering expansion of solar and wind power. Utility-scale solar capacity alone reached more than 880 gigawatts in 2024, a figure that dwarfs every other country on the planet. To put that in perspective, the entire electricity generation capacity of the United States across all fuel types is roughly 1,300 gigawatts. China is installing solar panels at a pace no other nation has matched, and wind power is scaling alongside it.
Nuclear energy is expanding rapidly as well. China currently has 23 nuclear reactors under construction, which will add roughly 24 gigawatts of carbon-free generation capacity over the next decade. That construction pipeline alone is larger than the total nuclear fleet of most countries. Nuclear fills a critical gap that solar and wind cannot: it generates steady, round-the-clock power regardless of weather.
Despite all of this, coal still accounts for about 62% of China’s total energy consumption. The country’s industrial structure leans heavily on energy-intensive manufacturing, and coal remains deeply embedded in electricity generation and heating. The challenge isn’t just building renewables. It’s building them fast enough to displace coal while the economy continues to grow.
Electric Vehicles Are Now Nearly Half of New Sales
China has become the world’s largest electric vehicle market by a wide margin. In 2024, 48% of all passenger vehicles sold in the country were electric, totaling 11 million sales in a single year. That puts China tied with the Netherlands for the highest EV share among major economies, trailing only a handful of smaller European countries like Norway (92%) and Sweden (58%).
This shift didn’t happen by accident. Years of government subsidies, manufacturing incentives, and charging infrastructure investment created the conditions for domestic companies like BYD to scale rapidly. The impact on emissions is significant: passenger car emissions in China are projected to peak around 2025, with truck emissions following around 2030. Transportation is one of the fastest-growing sources of carbon pollution globally, so electrifying it early gives China a meaningful head start on bending its emissions curve downward.
Cutting Carbon Intensity Across the Economy
China measures progress not just by total emissions but by carbon intensity, the amount of CO2 released per unit of economic output. Under its Paris Agreement commitment, China pledged to reduce carbon intensity by more than 65% from 2005 levels by 2030. By 2020, it had already achieved a 48.4% reduction. Between 2020 and 2024, intensity fell by another 7.9%, putting the country on a trajectory to meet or exceed its target.
This metric matters because it reflects how efficiently the economy uses energy. Even as China’s GDP has grown enormously, each dollar of output produces less pollution than it used to. The limitation of this measure is obvious: if the economy grows fast enough, total emissions can still rise even as intensity falls. That’s exactly what has happened for much of the past two decades. The goal now is for efficiency gains and clean energy deployment to outpace economic growth so that absolute emissions begin declining.
Cleaning Up Heavy Industry
Steel and iron production is one of China’s largest industrial sources of emissions and air pollution. The government has imposed increasingly strict emission standards on the sector in waves. Standards introduced in 2012 were tightened in 2015, cutting allowable limits for particulate matter by 60% and sulfur dioxide by 67%. Further revisions in 2017 and 2019 pushed limits even lower, with the “ultra-low emission” standards of 2019 setting some of the strictest thresholds in the world for steel plants.
These regulations forced steel producers to install advanced pollution control equipment. The country’s 12th Five-Year Plan mandated desulfurization systems on all sintering machines (a major source of steel plant pollution) by 2015. More recently, the majority of new steel denitrification projects have adopted catalytic reduction technology, which strips nitrogen oxides from exhaust before they reach the atmosphere. While these measures primarily target air pollutants like sulfur dioxide and particulate matter, the broader push to modernize and consolidate the steel industry also drives energy efficiency improvements that reduce CO2.
Expanding Forests as Carbon Sinks
China has been running one of the world’s largest reforestation campaigns for over two decades. By 2022, national forest coverage reached 24.02%, and the government has committed to increasing that to 26% by 2035. These forests act as carbon sinks, pulling CO2 out of the atmosphere as trees grow.
Reforestation won’t offset the scale of China’s industrial emissions on its own, but it plays a meaningful supporting role. Forests also deliver co-benefits like reducing soil erosion, improving air quality, and supporting biodiversity. The 26% target represents a substantial increase from the early 2000s, when coverage was closer to 18%.
Hydrogen and Emerging Clean Technologies
China is also investing in green hydrogen, produced using renewable electricity to split water rather than relying on natural gas. The country’s hydrogen development plan set targets of 50,000 hydrogen fuel-cell vehicles and 100,000 to 200,000 tonnes of green hydrogen production per year by 2025, supported by a growing network of hydrogen refueling stations.
Hydrogen is particularly relevant for sectors that are hard to electrify directly, like long-haul trucking, shipping, and certain industrial processes. The volumes are still small compared to China’s overall energy system, but the investment signals a long-term bet on hydrogen as a complement to batteries and grid-scale renewables.
The Scale of the Challenge
China’s emissions reduction efforts are genuinely massive in absolute terms, but so is the gap between where the country stands today and carbon neutrality by 2060. Coal still dominates the energy mix. Total emissions have continued rising even as intensity drops. And the compressed timeline between peaking (before 2030) and neutrality (before 2060) gives China roughly 30 years to eliminate net emissions, a faster transition than what most developed countries have planned for themselves.
What makes China’s situation unique is the sheer scale on both sides of the ledger. It is simultaneously the world’s largest emitter and the world’s largest deployer of clean energy. Whether it meets its targets depends on how quickly the buildout of solar, wind, nuclear, EVs, and hydrogen can overtake the deeply entrenched role of coal in powering the world’s second-largest economy.
