EU Story: China’s Climate Shift Signals Structural Change in Global Emissions

As almost all countries throughout the world are making efforts to reduce global warming, exciting news has come from the People’s Republic of China (China or PRC). Planet-warming emissions from China have continued to flatline or fall as cleaner forms of energy outpace coal and gas generation.

This trend, if sustained, could mark a pivotal turning point. Analysts suggest that China’s emissions from energy production may peak within the next two years, signaling a structural shift in global fossil fuel dependence and a critical milestone in efforts to slow atmospheric warming. According to research from the Centre for Research on Energy and Clean Air, emissions across major sectors have declined over the past year, continuing a slowdown that began in May 2024.

China’s approach has been deliberate: aggressively scaling renewable energy technologies while acknowledging its role in the global climate crisis and the necessity of emissions reduction targets.

“This is an important piece of work,” noted Jackson Ewing, director of energy and climate policy at the Nicholas Institute for Energy, Environment and Sustainability. “Given that we’re looking at close to a two-year plateau and slight decline, it’s more likely than ever that this is here to stay. The overall emissions trajectory for China is likely to remain relatively flat in the near term before beginning a more pronounced decline.”

China became the world’s largest greenhouse gas emitter in 2006, surpassing the United States. However, its historical contribution to cumulative emissions remains comparatively lower—accounting for approximately 11% of global emissions between 1850 and 2021. On a per-capita basis, China’s emissions are roughly half those of the U.S.

Key 2025 Developments

Several indicators from 2025 reinforce the momentum behind China’s clean energy transition:

• CO₂ emissions declined year-over-year across most major sectors:

  • Transport: down 3%

  • Power generation: down 1.5%

  • Building materials: down 7%

• The chemicals sector was a notable exception, with emissions rising 12%.

• Clean energy expansion accelerated:

  • Solar output increased by 43%

  • Wind power grew by 14%

  • Nuclear energy rose by 8%

• Coal generation declined by 1.9%, reflecting displacement by renewables.

Global Context and the Paris Agreement Gap

China’s progress must be viewed within the broader international climate framework. Of the 194 signatories to the Paris Climate Agreement, only a small fraction—approximately 15 countries—are currently on track to meet their commitments. Most of these are smaller nations, while major emitters such as China, the United States, India, and the European Union remain off course to meet even the 2°C target, let alone the more ambitious 1.5°C goal.

This already fragile trajectory is now further complicated by escalating geopolitical tensions involving Iran and the reported disruption of oil flows through the Strait of Hormuz—a critical chokepoint through which a significant share of the world’s oil supply passes. Any sustained blockage or instability in this corridor has immediate implications for global energy markets, typically driving sharp increases in oil prices. In the short term, such price shocks can incentivize expanded fossil fuel production and consumption among major economies seeking energy security, potentially undermining emissions reduction efforts and delaying clean energy transitions.

Compounding this global shortfall are recent policy reversals in the United States under Donald Trump. As in his previous term, Trump has withdrawn the U.S. from the Paris Agreement. Additionally, on February 12, 2026, his administration revoked the “endangerment finding”—a cornerstone of federal climate policy established in 2009 by the Environmental Protection Agency. That ruling had determined that six key greenhouse gases, including carbon dioxide (CO₂), posed a threat to public health, thereby mandating regulatory action.

Further actions have included efforts to curtail the expansion of renewable energy sources such as wind and solar, while increasing reliance on oil and coal. In the context of rising global oil prices and supply uncertainty tied to tensions in the Persian Gulf, these policy shifts risk reinforcing fossil fuel dependence at precisely the moment when coordinated international decarbonization is most critical.

Conclusion

China’s emissions plateau—and potential near-term peak—represents a significant inflection point in the global climate landscape. However, the convergence of geopolitical instability, energy market volatility, and policy divergence among major powers introduces new uncertainty into the pace of the global energy transition. While China’s trajectory demonstrates that large-scale emissions stabilization is achievable, the broader question is whether other major emitters will maintain that course amid rising security concerns and economic pressures tied to fossil fuel supply.
