Following the onset of the US-Israeli conflict concerning Iran, China’s carbon dioxide emissions experienced a decline of 1%. This reduction can be attributed to a significant decrease in oil consumption alongside an increase in the adoption of electric vehicles and the use of public transportation, according to a recent analysis.
The findings highlight the impact of clean energy in mitigating price fluctuations arising from the crisis in the Strait of Hormuz, particularly for China, the world’s largest oil importer. These developments have led to renewed optimism regarding China’s progress towards decarbonizing its economy, given its status as the leading emitter of greenhouse gases globally.
Despite a 32% drop in oil imports, China’s overall transportation activity saw an increase, as revealed by second-quarter energy statistics from the National Bureau of Statistics, which were analyzed by the Centre for Research on Energy and Clean Air for Carbon Brief. This reduction in oil imports, amounting to nearly one million barrels per day, played a role in stabilizing global oil prices, which nevertheless rose by approximately 60% following the initial US airstrikes in late February.
The mechanisms behind this decrease in imports have drawn considerable attention. The analysis indicates that around two-thirds of the decline stemmed from the depletion of existing strategic oil reserves rather than the establishment of new ones, while the remaining third was primarily attributed to diminished demand.
Overall oil consumption in China fell by 9%, with a 16% decrease specifically in the transportation sector. During this time, while many petrol and diesel vehicles were off the roads, there was a notable increase in the use of electric cars, buses, trains, and trucks.
This trend towards electrification had begun well before the crisis in the Strait of Hormuz. China stands as the largest global producer, consumer, and exporter of batteries, electric vehicles, wind turbines, and solar panels. The disruption in oil supply from the Gulf has underscored the economic and strategic necessity for China to lessen its reliance on petroleum.
In the first half of 2026, the shift towards electric vehicles in China was significant enough to displace oil consumption equivalent to that of the entire United Kingdom over six months.
Experts anticipate that much of this reduced demand may persist even if global oil prices decrease. Lauri Myllyvirta, the lead analyst at the Centre for Research on Energy and Clean Air, stated, “There is no doubt that the decarbonization of the transport sector has accelerated.” He emphasized that this situation validates China’s energy security strategy and highlights electrification as a resilient approach to mitigate such shocks.
Myllyvirta also pointed out that this marks the first instance where a decrease in emissions in China has been linked to reduced oil consumption instead of coal usage.
Interestingly, coal generation actually increased during the quarter due to changing economic incentives and delays in adapting the energy grid, which resulted in significant wastage of wind and solar energy. Nonetheless, many analysts believe that the long-term trajectory for China is a move away from fossil fuels.
Dr. Muyi Yang, a senior analyst at Ember, which is preparing to release a report on China’s energy trends next week, noted that a peak in fossil fuel usage is becoming apparent at both provincial and sectoral levels. He suggested that the situation in Iran strengthens the argument for reducing oil dependence, stating, “The way China has managed to absorb the impacts reinforces confidence to pursue deeper changes.” He concluded that minimizing exposure to geopolitical risks associated with oil imports is a more effective strategy, a lesson illustrated by China’s recent experiences.
