China's CO2 Emissions Fall 3.1% as Clean Power and Lower Oil Use Reshape Demand

Clean electricity outpaces demand as emissions fall

China's carbon dioxide emissions fell an estimated 3.1% in the third quarter of 2026 compared with a year earlier, the largest quarterly reduction since the COVID-19 lockdowns of 2022. Growing clean electricity production, falling transport fuel consumption and weaker construction activity combined to bring estimated emissions for the first nine months of the year down 0.5%.

The Center for Research on Energy and Clean Air (CREA), using official figures and commercial data, calculated that coal consumption fell 3% and oil use declined 4% between July and September. Transport oil consumption dropped faster, falling 9%, as disruption to shipping through the Strait of Hormuz added pressure to a market already changing through vehicle electrification.

Solar, wind and nuclear plants generated an additional 110 terawatt hours of electricity compared with the same quarter a year earlier. That increase was more than twice the growth in electricity demand and roughly equivalent to Germany's entire electricity output over the same period. A terawatt hour is one billion kilowatt hours, the unit commonly used on household electricity bills.

China's emissions have now followed a broadly flat or falling trend since March 2024. Sustaining that direction depends on whether clean energy keeps expanding faster than demand, how quickly electricity networks can absorb new generation, and whether economic support revives industries that consume large amounts of coal and oil.

How the decline developed

China's latest quarterly fall extends a change that began more than two years earlier. The dates show how electricity generation, transport and industrial demand have moved together:

• March 2024: The period of broadly flat or falling CO2 emissions began.
• July to September 2026: Emissions fell 3.1%, coal use dropped 3% and oil consumption declined 4% compared with a year earlier.
• September 2026: Electric vehicles reached a reported 67% of passenger car sales and 50% of heavy truck sales.
• January to September 2026: Estimated CO2 emissions fell 0.5%, while reported GDP grew 4.6%.

The difference between the quarterly emissions decline and the smaller fall over nine months shows that the reduction became stronger in the latest period. The economic figures also show that falling emissions accompanied continued growth, although activity varied sharply between sectors.

Why coal power fell despite new plants

Coal power generation declined 3.3% in the third quarter as electricity demand growth slowed and clean generation increased. Wind and solar farms also lost less potential output through curtailment, the term for electricity they could produce but cannot deliver because of network limits or operating restrictions.

China continued building coal power capacity at close to record rates. Capacity measures how much electricity plants could produce, while generation measures what they actually produce. Adding plants while total coal generation falls means the expanding fleet runs for fewer hours on average.

Fewer operating hours weaken plant earnings because owners must still cover financing, maintenance and staffing costs. The immediate change is therefore visible in both the electricity mix and the economics of coal generation: more equipment is competing to supply a shrinking amount of coal power.

China's monthly electricity generation series, attributed to the National Bureau of Statistics, lists 943.85 terawatt hours in July, 943.78 in August and 829.36 in September. Those figures total 2,716.99 terawatt hours for the quarter. They provide a sense of the power system's scale; the clean energy increase of 110 terawatt hours was large enough to cover more than twice the additional demand identified in the emissions analysis.

The bureau's release "Energy Production in September 2026", published on October 19, 2026, gives September electricity generation rounded to 829.4 terawatt hours in its electricity production section. Its production figures cover industrial enterprises with annual main business revenue of at least 20 million yuan.

Oil demand faces a shipping shock and a lasting shift

The Strait of Hormuz crisis disrupted a crucial route for oil shipments to China, the world's largest crude importer. The resulting pressure on supplies and prices helped reduce oil demand during the quarter, alongside changes already taking place in road transport.

CREA co-founder and lead analyst Lauri Myllyvirta said cheaper oil could bring some consumption back:

It's clear there is going to be some kind of a rebound in oil consumption once, or if, prices come down,

Myllyvirta also said China's oil consumption had highly likely peaked before the shock and that the disruption accelerated electrification and the shift away from oil. His assessment points to two forces operating together: a sudden constraint on oil consumption and a longer change in the vehicles and energy systems people use.

Transport oil use fell 9%, compared with the 4% decline across all oil consumption. The steeper transport reduction shows why roads are central to the change, while other uses of oil, including industrial feedstocks, continue to shape total demand.

Electric vehicles take a larger role in daily travel

Electric vehicles reached a reported 67% of passenger car sales in September, while their share of heavy truck sales reached 50%. GL Consulting describes the passenger figure as the share of retail sales taken by new energy vehicles, a Chinese category that includes fully electric vehicles and plug-in hybrids.

Electricity consumed by electric vehicles rose 53%, faster than the number of such vehicles on the road. That pattern indicates that existing electric vehicles were being used more intensively, with drivers choosing them more often instead of vehicles powered by petrol or diesel.

GL Consulting's energy demand assessment, published on November 4, puts the transport changes alongside weaker demand elsewhere. It records third quarter gasoline consumption falling 8.2% and diesel consumption declining 10%. Diesel demand is particularly sensitive to construction, freight and industrial activity, so weaker building activity also helps explain the fall.

Charging infrastructure is handling more activity as travel shifts toward electricity. In August, electricity use by charging and battery swapping services increased 51.2% from a year earlier. That monthly service sector measure and the 53% increase in electricity consumed by electric vehicles cover different periods and activities, but both show expanding demand for charging.

Economic growth shifts away from construction

China's GDP grew 4.5% in the third quarter and 4.6% over the first nine months of 2026, according to figures cited by GL Consulting. GDP measures the value of goods and services produced, but the energy needed to generate that value depends heavily on which industries are growing.

Fixed asset investment fell 7.2% in the first nine months. Real estate development investment dropped 20.6%, while manufacturing investment fell 2.1%. The property contraction helps explain falling CO2 emissions from cement and steel production: fewer construction projects mean less demand for these materials and the fuel needed to make them.

Exports and advanced manufacturing provided stronger support. Merchandise exports rose 28.4% in the third quarter in US dollar terms. GL Consulting estimates that net exports contributed 45.2% of GDP growth during that period, close to the 45.0% contribution it assigns to final consumption. Those contribution figures are the consultancy's calculations.

High technology manufacturing output grew 14.3% during the first nine months, compared with 5.3% for industrial output across the economy. China was therefore growing through a different mix of activities, with technology production expanding while property investment contracted sharply.

Electricity demand grows in different places

Advanced manufacturing and digital services continued to use more power even as traditional fuel demand weakened. In August, electricity consumption in high technology and equipment manufacturing rose 7.2%, while internet data services used 37.9% more electricity than a year earlier.

Those increases matter for electricity networks because new demand can emerge far from existing generation or in places where local connections need expansion. Charging stations, factories and data facilities all need reliable power, even when national demand growth is slowing.

Exceptionally mild weather also helped restrain energy demand in the third quarter by reducing some temperature driven consumption. Weaker economic growth contributed as well. The emissions decline therefore combined more clean energy with slower demand growth, rather than depending on either factor alone.

Clean power growth is expected to exceed total energy demand growth for the year if the current balance continues. The practical test is whether new generation can reach consumers when needed, allowing electricity to replace more fossil fuel use.

Chemicals and construction add to the decline

China's coal to chemicals industry, previously a major source of emissions growth, expanded more slowly during the third quarter. These plants turn coal into chemical products, using it as both a raw material and an energy source.

Higher coal prices weakened profitability, while higher chemical product prices reduced demand from businesses buying those products. Slower growth in this sector reduced a source of upward pressure on emissions just as coal power and transport fuel consumption were falling.

Cement and steel emissions also continued to decline as the contraction in construction accelerated. For producers, the immediate effects include weaker orders and less need to operate furnaces, kilns and other equipment that consumes large amounts of energy.

The contrast with technology manufacturing is central to understanding the quarter. Expanding electronics production and digital services increased electricity demand, while shrinking construction reduced demand for materials and fuels. A single GDP growth rate can conceal these very different conditions.

Grid access and economic policy shape the next stage

China's electricity networks will help determine how much additional wind and solar generation can replace coal. Reducing curtailment means putting existing clean energy equipment to fuller use, while stronger connections and storage can help move electricity across regions and between times of high and low production.

Gao Yuhe, project lead at Greenpeace East Asia, identified continued reductions in coal generation as central to renewable energy development:

Coal power sustaining a downward trend is a key factor in the further development of renewable energy,

Gao also called for greater renewable energy uptake, market development and energy storage. Storage can hold electricity produced during sunny or windy periods for use later, helping the system meet demand when renewable output falls.

Government economic support presents another influence. Announced stimulus focuses on six networks, including electricity and transport infrastructure, areas already covered by policies promoting green and zero carbon solutions. The emissions outcome will depend on which projects proceed and how much demand they create for steel, cement, electricity and transport fuels.

Reported GDP growth remains within the government's target, reducing pressure for further stimulus. No firm date has been established for a sustained oil demand rebound or a permanent emissions peak. China's longer term commitment is carbon neutrality by 2060, meaning that remaining carbon emissions would be balanced by removals.
