China’s carbon dioxide (CO2) emissions fell by 1% within the second quarter of 2026, as oil consumption plummeted amid the strait of Hormuz disaster.

The nation’s use of oil fell by 9% total and by 16% for transport, after the disruptions to produce from the Gulf by means of the strait.

China’s complete CO2 emissions fell regardless of a continued rebound in coal-fired energy era.

That is the primary time that reductions in oil consumption have been accountable for a fall in CO2 emissions total – in all earlier instances, coal consumption has been the primary driver.

Different key findings for the second quarter of 2026 embody:

• Electrical automobiles (EVs) and public transport have change into key components in China’s oil demand, enabling transportation ranges to extend whilst gas use fell sharply.
• The impact of EVs on oil consumption was nearly twice as massive as can be anticipated based mostly on the rise within the variety of EVs on the street alone, because the utilization of present EVs surged.
• Oil consumption displaced by EVs in China within the first half of 2026 exceeded the UK’s complete oil consumption over a six-month interval.
• These structural components should not enough to account for the dimensions of the autumn in oil consumption, leaving behaviour modifications as the opposite rationalization.
• “Curtailment” of photo voltaic and wind output triggered coal energy to rise, regardless of robust hydro output, photo voltaic and wind capability development, in addition to slower demand development.
• Main will increase in coal-power capability and an influence market that continues to favour coal restricted the quantity of coal era displaced by new wind and photo voltaic capability.
• Defying expectations of a growth, annual development in coal use for chemical compounds manufacturing slowed down to eight%, from 15% in 2025 and 19% within the first quarter.

The second quarter of 2026 was a busy time for China’s authorities planners, with quite a few energy-related five-year plan paperwork being launched.

These plans record new measures to deal with photo voltaic and wind curtailment, in addition to signalling a better bar for the approval of latest coal-power vegetation, however add few new quantitative targets.

After a 2% improve within the first quarter of 2026 and a 1% decline within the second, emissions are up marginally throughout the primary half of the 12 months, however they continue to be beneath their peak in 2023-24.

As well as, China is on observe so as to add sufficient wind, photo voltaic, nuclear and hydropower this 12 months to cowl electrical energy demand development, regardless of a slowdown in new capability.

Given the structural pressures on oil demand, continued declines in real-estate development and slower development for coal-chemicals, China’s emissions might nonetheless fall this 12 months. The emission development stays a race between vitality demand development and clean-energy development, each of which have slowed down this 12 months.

Emissions nonetheless flat

There has now been a plateau in China’s CO2 emissions from fossil fuels and cement for greater than two years, following a peak in March 2024.

Earlier evaluation for Carbon Transient described this as a “flat or falling” development, which prolonged till the top of 2025. There was then a 2% improve in emissions year-on-year within the first quarter of 2026, ensuing from an increase within the quantity of “wasted” wind and solar energy.

The most recent evaluation reveals that this was adopted by one other decline within the second quarter of this 12 months, when China’s emissions fell by 1%, as proven within the determine beneath.

For additional particulars see: In regards to the knowledge. 

Notably, China’s emissions fell within the second quarter regardless of a rise in coal use. For the primary time ever, a drop in oil use was enough to drive a decline in emissions total.

Oil use plummeted whereas coal grew

Throughout the total 1% decline in China’s emissions within the second quarter of 2026, there have been divergent developments when wanting sector by sector and gas by gas.

The most important fall in CO2 emissions got here from the consumption of petrol, diesel and jet gas, with oil consumption in business additionally falling, as proven within the determine beneath.

For additional particulars see: In regards to the knowledge. 

Crude oil processing volumes fell 11% within the second quarter, however a number of the fall was absorbed by drawing down oil product inventories, with Sinopec gross sales down 9%.

In complete, China reduce oil imports by 32% within the second quarter. The million–barrel query has been how a lot of this was enabled by real reductions in oil consumption and the way a lot by the drawdown of the nation’s huge oil stockpile.

Vitality combine numbers reported by the Nationwide Bureau of Statistics point out that oil consumption fell by 3% within the first half of the 12 months and round 9% within the second quarter. This reveals that diminished consumption performed a considerable function, whereas nonetheless leaving 60% of the autumn in imports to be coated by the swing from constructing stockpiles to utilizing them.

The sector with the most important improve in emissions through the second quarter of the 12 months was energy, the place coal use grew 2.4% whereas gas-fired era fell 1.2%. This was regardless of robust development in wind and photo voltaic capability over the previous 12 months, a big rebound in hydropower era, a small improve in nuclear energy output and a slowdown in electrical energy consumption development.

The reason for the rise in emissions was – just like the primary quarter of 2026 – an elevated quantity of photo voltaic and wind era being “wasted” as a result of energy market and grid not being tailored to growing shares of variable renewable era.

In different sectors, there was a fall in cement manufacturing, pushed by falling development volumes, which accelerated to 9% within the second quarter, from 8% within the first quarter. Crude metal output fell by 1% and pig-iron manufacturing by 3% within the second quarter.

Development of coal use for chemical manufacturing slowed down within the second quarter, each in contrast with the earlier quarter and the final 12 months.

The speed of utilisation of put in coal processing capability was already excessive earlier than the present oil shock, so there was no headroom for manufacturing to extend regardless that rising oil costs made coal-chemicals extra worthwhile. Oil-based chemical manufacturing additionally saved rising, with ethylene output up 17% and first plastics manufacturing flat.

Coal use for heating continued to extend, with the sector’s coal consumption within the second quarter dominated by industrial warmth, as there’s no need for area heating right now of 12 months. Development has continued regardless of the outstanding drive for “zero-carbon industrial parks”, demonstrating the significance of the initiative for tackling industrial coal use.

What drove the autumn in oil consumption?

The dramatic fall in China’s demand for oil imports through the Hormuz disaster has been extensively hailed as crucial value stabilising issue for the worldwide oil market.

To grasp the implications for China’s oil consumption and CO2 emissions going ahead, it is very important unpack what enabled this discount in imports.

A major contribution comes from ongoing, structural reductions in transport oil demand pushed by electrification. Sinopec had forecast 6% and 5% drops in diesel and petrol consumption this 12 months, respectively, already earlier than the beginning of the conflict on Iran. Precise gross sales fell 9% within the first half of the 12 months.

Transportation ranges present a slowdown in development, however no outright decline. Cross-regional passenger journeys had been 0.1% larger year-on-year within the second quarter, whereas city passenger journeys had been 2.9% larger. Industrial freight tonnage elevated 2.4%.

The exception is air journey, the place passenger numbers fell 7% in Could-June, after 7% development within the first quarter. Nevertheless, this sector performs a minor function in total transport oil consumption in China.

The steady or rising transportation ranges present that the shift to electrical automobiles, rail, public transport and different clear transportation, reasonably than a fall in mobility, performed the important thing function in lowering oil consumption.

The rise in gas costs that accompanied the Hormuz disaster solely accelerated the structural shifts in transportation that had been already underway.

Electrical heavy-truck gross sales rose about 77% within the second quarter, year-on-year, with June gross sales greater than doubling and the market share of electrical vehicles exceeding 45% of all new gross sales.

The full variety of EVs on the street on the finish of the quarter grew 33% year-on-year. Some 12.1m EVs had been added, of which 8.1m had been electric-only battery EVs.

EV utilization noticed much more of a shift. Charging volumes elevated 60% within the second quarter, indicating that EVs already on the street had been utilised rather more than earlier than, on the expense of petrol and diesel automobiles, with plug-in hybrid drivers doubtless favouring electrical energy over gas.

One issue enabling EV utilisation to develop was the elevated use of electrical taxis. Intense competitors within the sector has pushed costs down concurrently the usage of personal petrol automobiles has change into costlier.

Stronger subway and rail use additionally made a contribution. Rail-passenger site visitors elevated 5% within the first half of the 12 months.

The autumn in diesel demand has been notably pronounced within the development and mining sectors. The heavy equipment within the sectors is well-suited for electrification, along with which development ranges are additionally falling.

Based mostly on reported development in charging volumes, EVs helped keep away from an estimated 19m tonnes of oil consumption (Mtoe) within the second quarter, up 50% year-on-year.

This took the entire quantity of oil displaced by EVs to 36 Mtoe within the first half of the 12 months, as proven within the determine beneath, effectively exceeding, say, the entire oil consumption of the UK over six months. Notably, vehicles are the fastest-growing supply of oil displacement, with prevented gas expend 90% year-on-year within the first half of 2026.

For additional particulars see: In regards to the knowledge. 

The rise in prevented oil consumption as a consequence of EVs is the same as 4.5% of China’s oil imports in the identical interval in 2025. If EV gross sales and charging volumes proceed their development on the identical charges within the second half of the 12 months, prevented oil consumption will attain 80 mn tonnes, equal to the consumption of Mexico.

Estimated emissions prevented are 35 MtCO2, or 1.3% of China’s complete CO2 emissions within the second quarter, after taking into consideration emissions from energy era for automobile charging.

Whereas the quantity of oil displaced by the shift to EVs is critical – and is rising quick – the year-on-year improve in displaced oil nonetheless solely accounts for a 3rd of the drop in China’s oil consumption within the first half of the 12 months, with the autumn in consumption solely accounting for half of the drop in imports. The remaining discount is as a result of shift from constructing to drawing down stockpiles, slower development in chemical business output, in addition to behavioral variations by shoppers and operational variations by companies.

Coal energy continued to rise regardless of clean-capacity development

China noticed file will increase in photo voltaic and wind capability over the previous 12 months. As well as, hydropower era elevated 9% within the second quarter of the 12 months, in contrast with the identical interval in 2025, and there was a small 2% improve in nuclear-power output.

On the identical time, the speed of energy demand development slowed down from 5.9% within the second quarter of 2025 to five.2% in the identical interval in 2026.

But, power-sector emissions elevated 3.0% within the first half of 2026, after falling 3.2% within the first half of 2025. Energy era from fossil fuels rose due to a rise within the quantity of potential photo voltaic and wind era that was wasted, in addition to exceptionally poor wind circumstances. With out these components, coal-fired energy era and power-sector emissions would even have fallen in 2026.

Wind-power capability has continued robust development in 2026, with capability additions in each the primary and the second quarter of the 12 months comfortably exceeding these in any 12 months apart from the record-setting 2025.

Solar energy additions have slowed sharply from the charges seen in 2025, even falling behind 2024. But, they’re in keeping with 2023, when greater than 200 gigawatts (GW) was added by year-end.

Nuclear energy improvement continues at tempo, with eight new reactors authorized in July and 5 reactors with 4.5GW complete capability anticipated to enter business operation this 12 months. This consists of China’s second business small modular reactor, Linglong One, with new insurance policies paving the way in which for additional improvement.

Reactor commissioning will choose up additional subsequent 12 months: the federal government has authorized 10 new reactor tasks yearly since 2022 and people tasks will start to come back on-line. In the meantime, 3GW of standard hydropower was added, with a complete of 6GW of tasks focusing on operation in 2026.

Taken collectively, this clean-energy development places China on observe so as to add sufficient non-fossil producing capability in 2026 to cowl electrical energy demand development of as much as 5%, regardless of the slowdown in photo voltaic.

Energy demand grew 5.3% within the first six months of 2026 and the vitality regulator tasks 5-6% for the entire 12 months. Which means that the rise in power-sector emissions seen within the first half can be reversed, as soon as the obstacles to photo voltaic and wind sending their output to the grid are addressed – and as soon as wind circumstances revert to common ranges.

Furthermore, complete vitality demand development has slowed down rather more sharply than electrical energy demand, making it extra possible for clean-power era development to considerably exceed the rise in complete vitality consumption and to drive down fossil-fuel consumption.

For additional particulars see: In regards to the knowledge.

The key motive for photo voltaic and wind curtailment in China is that neither the power-grid working mannequin nor the electrical energy market mannequin require – or encourage – the versatile operation of coal-power vegetation, hydropower vegetation and inter-provincial transmission traces.

This example has been exacerbated by a wave of latest coal-power vegetation getting into operation, with newly added capability reaching 30GW within the first half of 2026, the best degree since 2016. One other 25GW began development, whereas lower than 3GW was retired.

The electrical energy costs paid to coal-fired turbines are fastened months prematurely, as are the volumes of electrical energy that can be transmitted by means of long-distance energy traces.

This removes the inducement for vegetation to regulate their output in response to circumstances. This might embody variations in photo voltaic and wind provide, or modifications in energy demand.

In consequence, there’s restricted means for the grid to soak up variable renewable energy. Moreover, coal vegetation are entitled to “capability funds”, which require them to be obtainable to generate, however don’t reward them for working flexibly.

One answer to combine extra photo voltaic and wind into the grid is growing vitality storage capability. Battery storage capability continued to develop, with 17GW added within the first half of 2026, bringing complete put in capability to 153GW. This represents a slowdown in storage additions, nonetheless, down from 23GW within the first half of 2025.

Outlook for China’s CO2 emissions

The important thing developments affecting the outlook for China’s emissions within the second quarter embody the results of the Hormuz oil-and-gas disaster, the discharge of a protracted record of sectoral five-year plans and a slowdown in vitality consumption development.

The rise in oil costs has triggered a stronger shift in China’s transportation sector than anybody anticipated, with EV deployment and use accelerating from an already excessive base. This development is unlikely to be reversed. It has additionally confirmed the worth of electrification to China’s vitality safety technique.

The federal government is focusing on a slight acceleration within the tempo of electrification, aiming for electrical energy to make up 35% of vitality end-use by 2030, up from 30% in 2025. This can be a bigger improve than achieved over the previous 5 years, when the share of electrical energy rose from 26.5% in 2020 to 30% by 2025. The transportation sector performs a big function on this, with a goal for EVs to make up 30% of the automobile fleet, up from 12% in 2025, and 25% of business automobiles.

Electrification each reduces emissions instantly and units completely different sectors up for deep decarbonisation as electrical energy is way simpler to supply with out CO2 emissions than fuels. Quicker transport sector electrification lowers the outlook for oil demand, will increase the function of the sector in peaking and lowering emissions, plus signifies that extra of China’s clear vitality development finally ends up displacing oil.

Whereas transport emissions fell, power-sector emissions continued to rebound for the second quarter in a row. The elevated coal-fired energy era and emissions will be attributed to elevated photo voltaic and wind curtailment. Curtailment has emerged as the important thing impediment to each continued fast photo voltaic and wind capability development and full utilisation of present capability.

A number of sectoral five-year plans revealed in current months have laid out measures to enhance photo voltaic and wind utilisation.

Lengthy-distance transmission will proceed to develop, serving to to maneuver wind and photo voltaic era from distant “vitality bases” to centres of demand. There may be additionally a rising emphasis on native consumption of fresh energy. The energy sector five-year plan, revealed in August, promotes direct purchases of fresh electrical energy, good microgrids, zero-carbon industrial parks and nearer coordination between renewable sources and AI computing infrastructure

But the identical plan additional loosened the bounds on the quantity of wind and photo voltaic that may be curtailed.

The restrict for curtailment was 5%, till it was relaxed to 10% in 2024 in provinces with good wind and photo voltaic sources. The brand new plan permits the restrict to be elevated additional to fifteen% for some provinces, whereas retaining it at 5% and 10% for others.

Trying on the 2025 knowledge on reported curtailment, only a few provinces had larger charges than 15% – solely Tibet for wind and Qinghai and Tibet for photo voltaic.

Until probably the most lenient restrict is just utilized to these two provinces, it means the plan would enable for larger ranges of curtailment.

That is additionally true of the nationwide common goal of “round” 10% curtailment, given reported charges in 2025 had been 94% and 95% for wind and photo voltaic, respectively.

Notably, month-to-month knowledge on curtailment has not been revealed in current months, elevating the chance that the indicator is being revised. Reported knowledge has understated precise curtailment by a large margin, in comparison with implied curtailment.

If the curtailment indicator is revised, such that it captures extra of the particular curtailment, then this might make the headline targets stronger than they seem, compared to beforehand reported numbers.

The brand new five-year plans additionally lowered the general degree of ambition on coal use. Chinese language president Xi Jinping introduced in 2021 that China would “progressively cut back coal consumption through the fifteenth five-year interval”, masking 2026-30. Nevertheless, the goal now could be for coal consumption to “enter a plateau” throughout these 5 years.

The five-year plans name for “moderately controlling coal-power capability and era”, signaling a better bar for the approval for brand spanking new coal-power tasks, after the federal government’s energetic promotion of latest coal energy lately. This might additionally suggest extra retirements of older coal vegetation. Nevertheless, there’s 204GW of coal-power capability underneath development, even after the wave of latest coal-power vegetation beginning operation in 2025 and within the first half of 2026, making the implementation of the “affordable management” more difficult.

It’s the first time that the federal government has vowed to manage “coal-power era” and never simply “era development”, because the vitality regulator did in 2021, however the significance of that distinction is unclear.

The renewable vitality five-year plan additionally broadens the idea of system reliability, which was a key justification for brand spanking new coal energy through the earlier 5 years. Slightly than relying totally on coal-fired energy for system stability, it more and more seems to be to different choices.

Alternate options embody storage, versatile demand, EVs, “digital energy vegetation” and smarter system operation to offer balancing providers. The plan additionally places an emphasis on growing the contribution of renewable vitality to assembly demand peaks.

Subsequently, whereas coal stays an essential backup useful resource within the plan, reliability is not framed as one thing that may solely be supplied by coal.

The Chinese language authorities has revealed quite a few different sectoral five-year plans since its overarching plan got here out in March. These embody plans for the vitality sector (“new-type vitality system”), energy system, renewable vitality, carbon peaking, coal, climate-change mitigation, and the setting (“Stunning China”). Some clear priorities emerge from these plans: electrification, electrical automobiles, vitality storage, offshore wind and “inexperienced”” fuels.

The vitality plan additionally considerably elevated ambition on the event of standard hydropower, regardless of ecological and social dangers and potential for tensions with neighbouring nations. The capability additions will largely solely materialise after 2030, nonetheless.

On the identical time, vitality consumption development has slowed down markedly after the surge throughout and instantly after the “zero-Covid” interval, making it extra possible for clear vitality to fulfill all incremental demand.

If this development continues, then complete CO2 emissions will start to fall whilst power-sector emissions proceed to plateau.

In regards to the knowledge

Information for the evaluation was compiled from the Nationwide Bureau of Statistics of China, Nationwide Vitality Administration of China, China Electrical energy Council and China Customs official knowledge releases, in addition to from business knowledge supplier WIND Data and from Sinopec, China’s largest oil refiner.

Electrical energy era from wind and photo voltaic, together with thermal energy breakdown by gas, was calculated by multiplying energy producing capability on the finish of every month by month-to-month utilisation, utilizing knowledge reported by China Electrical energy Council by means of Wind Monetary Terminal.

Complete era from thermal energy and era from hydropower and nuclear energy had been taken from Nationwide Bureau of Statistics month-to-month releases.

Complete major vitality consumption is transformed to the electrical energy equal utilizing the substitution technique.

Month-to-month utilisation knowledge was not obtainable for biomass, so the annual common of 52% for 2023 was utilized. Energy-sector coal consumption was estimated based mostly on energy era from coal and the common warmth charge of coal-fired energy vegetation throughout every month, to keep away from the concern with official coal consumption numbers affecting current knowledge.

CO2 emissions estimates are based mostly on Nationwide Bureau of Statistics default calorific values of fuels and emissions components from China’s newest nationwide greenhouse fuel emissions stock, for the 12 months 2021. The CO2 emissions issue for cement is predicated on annual estimates as much as 2024.

For oil, complete oil consumption is calculated based mostly on vitality combine knowledge for the first quarter and first half of the 12 months launched by the Nationwide Bureau of Statistics. Consumption of transport fuels – diesel, petrol and jet gas – is estimated based mostly on the gross sales development reported by Sinopec for the first quarter and the first half of the 12 months, with month-to-month disaggregation based mostly on manufacturing minus internet exports. The consumption of those three fuels is labeled as oil product consumption in transportation, as it’s the dominant sector for his or her use. Obvious consumption of different oil merchandise is calculated because the residual.

Estimated non-energy use of fossil fuels is subtracted from complete chemical business fossil gas consumption, and course of emissions are calculated based mostly on fossil gas consumption with carbon retained in merchandise subtracted. Emissions from the incineration of plastics are based mostly on a peer-reviewed estimate of plastics incineration in 2022, mixed with development charges within the total energy era from waste-to-energy vegetation. Metals business course of emissions are calculated utilizing industrial output knowledge and IPCC default emission components.

Oil consumption displaced by EVs is estimated utilizing China Affiliation of Car Producers’ gross sales knowledge, through Wind Monetary Terminal. The info breaks down automobile gross sales by kind and powertrain: passenger vehicles, buses, vans, semis and vehicles of various sizes, every cut up into battery-electric and plug-in hybrid, with assumptions about how far every automobile kind is pushed per 12 months and the gas financial system of the standard automobile it replaces.

Annual mileage and fuel-consumption assumptions are compiled from completely different sources, together with the Worldwide Council on Clear Transportation. Every electrical automobile offered is credited with avoiding the gas a comparable internal-combustion automobile would have burned; plug-in hybrids are credited solely with the portion of driving achieved on electrical energy (a utility issue of 64%).

The electrical energy and oil figures are calibrated to figures from China’s Nationwide Vitality Administration, which put new-energy-vehicle charging at 142.3 TWh in 2025 and reported 56.9% year-on-year development within the first half of 2026. The second half of 2026 is a projection: every automobile phase’s precise second-half-2025 displacement is grown by its first-half-2026 year-on-year charge.
