China’s falling emissions amid Iran war spark hope of decarbonisation watershed

China's carbon dioxide emissions fell by 1% in the second quarter of 2026, marking a notable shift in the nation’s approach to decarbonization. The decline was driven primarily by a steep drop in oil consumption, attributed to reduced imports and increased reliance on electric vehicles and public transport. This occurred amid heightened tensions stemming from the US-Israeli strikes on Iran, which disrupted global oil markets and prompted a reassessment of energy strategies. According to data analyzed by the Centre for Research on Energy and Clean Air, the reduction in oil use equated to approximately one million barrels per day, helping stabilize global oil prices despite a 60% surge in prices following the initial attacks. The decrease in oil consumption was partly due to the depletion of strategic reserves, with around two-thirds of the cut stemming from this factor. The remaining portion resulted from a deliberate reduction in demand, reflecting broader shifts in consumer behavior and policy-driven efforts to curb fossil fuel dependency. Meanwhile, China’s use of oil dropped by 9% overall, with a sharper 16% decline in transport sectors. This was accompanied by a surge in journeys made via electric cars, buses, trains, and trucks, underscoring the growing role of electrification in shaping the nation’s mobility landscape. China’s transition toward electric vehicles has gained momentum long before the recent geopolitical upheaval. As the world’s leading producer, user, and exporter of batteries, e-vehicles, wind turbines, and solar panels, the country has been actively promoting sustainable technologies. In the first half of 2026, the adoption of electric vehicles displaced the equivalent of the United Kingdom’s entire oil consumption over a six-month period. Analysts suggest that this trend is likely to persist, even if global oil prices eventually stabilize. Lauri Myllyvirta, lead analyst at the Centre for Research on Energy and Clean Air, emphasized that the transport sector’s decarbonization has been significantly accelerated, validating China’s energy security strategy. Despite the overall decline in emissions, coal generation saw an uptick during the quarter, influenced by shifting economic incentives and delays in modernizing the national grid. These delays led to the underutilization of renewable energy sources such as wind and solar, contributing to increased coal reliance. However, experts maintain that the long-term trajectory of China’s energy system is moving away from fossil fuels. Dr. Muyi Yang of Ember noted that a fossil fuel peak appears to be emerging at the provincial and sectoral levels, with the Iran crisis reinforcing this outlook. She highlighted the increasing risks associated with oil import dependence, suggesting that reducing such exposure is essential for long-term stability. The government has been actively working to address these challenges, releasing several energy-related five-year plan documents throughout the second quarter of 2026. These plans outline measures aimed at tackling solar and wind curtailment, as well as stricter criteria for approving new coal-power projects. Although these initiatives lack specific numerical targets, they signal a commitment to advancing clean energy infrastructure. Additionally, China is projected to install enough wind, solar, nuclear, and hydropower capacity this year to meet rising electricity demand, despite a slowdown in new installations. While emissions remained slightly above their pre-pandemic levels, they have plateaued for over two years, following a peak in early 2024. A temporary spike in emissions during the first quarter of 2026 was attributed to increased waste of wind and solar power, but this was offset by the subsequent 1% decline in the second quarter. Notably, this marked the first instance in which a reduction in oil use, rather than coal consumption, drove a nationwide drop in emissions. The interplay between energy demand growth and clean-energy expansion continues to shape China’s environmental trajectory, with ongoing efforts to balance these forces.
