China’s CO2 emissions fall as clean energy outpaces fossil fuels for the first time

Story: 2025 C.E.  |  Last updated: April 20, 2026

For the first time in its modern industrial history, China is posting a sustained, measurable decline in carbon dioxide emissions — driven by a clean energy buildout moving faster than almost anyone predicted. In the first half of 2025 C.E., China’s CO2 emissions fell 1% year-on-year, extending a downward trend that began in early 2024 C.E. The world’s largest greenhouse gas emitter added 212 gigawatts of solar capacity in just six months — a new global record — large enough to reduce fossil fuel use in the electricity sector even as overall energy demand kept rising.

At a glance

• China CO2 emissions: Fell 1% in the first half of 2025 C.E., continuing a decline that began in early 2024 C.E. — the first sustained drop in China’s modern industrial era.
• Solar capacity added: 212 gigawatts installed in just six months, setting a new global record and pushing clean power generation above rising electricity demand.
• Global clean tech dominance: China manufactures over 90% of the world’s solar modules and roughly 80% of its wind turbines, directly lowering costs for energy transitions worldwide.

Clean power outrunning demand

The core signal is this: China’s electricity demand kept rising in 2025 C.E., and clean energy still outpaced it. Solar led the charge, with wind and hydropower adding further weight. Together, they delivered enough new generation to displace coal-fired power at a scale that shows up clearly in national emissions data.

Grid investment rose 22% in the first half of the year — a sign that China is building the infrastructure needed to actually use all that variable renewable power rather than curtail it. Analysis from Ember, the energy think tank, confirms the trend is structural rather than cyclical. Emissions are falling while industrial output continues to grow, the kind of decoupling that climate economists have long argued was possible but rarely demonstrated at China’s scale.

This matters far beyond China’s borders. As the International Energy Agency documents, China’s manufacturing dominance has driven down the global cost of solar panels by more than 90% over the past decade. Every gigawatt it builds at home also makes clean energy cheaper and more accessible for countries that cannot yet afford it otherwise. That is a climate contribution that does not show up in any single national emissions figure.

A first absolute commitment — and its limits

The clean energy momentum has provided the foundation for a significant policy shift. China announced it would reduce greenhouse gas emissions across the economy by 7% to 10% below peak levels by 2035 C.E. That marks the first time China has committed to an absolute emissions reduction target rather than one measured against economic intensity — a meaningful structural change in how the country accounts for its climate obligations.

But experts from Climate Action Tracker argue the target is not ambitious enough. A 7% to 10% reduction is achievable with policies already in place and falls well short of the 30% or more that analysts say would align China with a 1.5°C trajectory. In other words, China is committing to do largely what it was likely to do anyway. The pledge should be read as a floor, not a ceiling — and the more important question is whether China raises ambition in future climate commitments, or whether a modest target becomes a reason to slow down.

The industrial sector complicates the picture

The decline in power-sector emissions is real and significant. The picture elsewhere is more complicated.

China’s industrial sector — particularly coal-to-chemicals and synthetic fuels — continues to expand. New coal power capacity is still being approved even as older plants are displaced by renewables. These trends create a gap between the progress visible in electricity generation and the full economy-wide emissions trajectory. According to the IEA’s overview of China’s energy plan, the tension between energy security goals and decarbonization timelines remains unresolved. China’s stated targets — peak emissions before 2030 C.E., net zero by 2060 C.E. — remain achievable in theory. Whether the industrial transition moves fast enough to support them is the open question.

What this moment signals for the world

Set aside the policy debate for a moment. What China is demonstrating in 2025 C.E. is that a large, fast-growing economy can begin bending its emissions curve downward through deployment of clean energy at massive scale. That proof matters enormously for other emerging economies watching to see whether decarbonization is compatible with growth.

It is. China is showing it.

Renewables now make up nearly half of global power capacity — a milestone China helped build. The country’s role in that shift is not incidental; it is central. According to global CO2 emissions data tracked by the EDGAR database, maintained by the European Commission and Netherlands Environmental Assessment Agency, China accounts for the largest share of global fossil CO2 — but its per-capita emissions, at 9.24 tonnes in 2023 C.E., remain well below the U.S. figure of 13.83 tonnes, a context that matters for any honest accounting of responsibility and progress.

The story of China’s emissions is not simple. It is a story of genuine, data-confirmed progress in the power sector, a historic policy commitment that climate advocates say is not yet ambitious enough, and an industrial expansion that creates real uncertainty about the path ahead. All three things are true at once. What is also true: the trend that matters most — clean energy outpacing fossil fuels in the world’s largest emitting nation — has now begun.
