A Global First: The World’s Biggest Polluter Switches From Fossil Fuels to Clean Energies — and the Planet Felt It

For the first time, China’s carbon emissions are falling — and not because of an economic slowdown or an energy crisis. Instead, a rapid expansion of clean energy sources is reshaping the country’s power landscape in a way that may have global consequences.

The drop, recorded in the first quarter of 2025, reflects a structural shift rather than a temporary correction. China’s emissions fell 1.6 percent year-on-year in the first three months of the year, with a broader decline of 1 percent over the previous 12 months. This marks the first period in which clean power growth alone, not a downturn, has led to a measurable reduction in emissions.

Coal Gives Way to Solar, Wind and Nuclear

Electricity demand in China has continued to rise, up 2.5 percent this year. Yet coal-fired power generation, long the backbone of the country’s energy system, declined by 4.7 percent. What made the difference was an unprecedented buildout of renewable energy. In March alone, 23 gigawatts of solar and 13 gigawatts of wind capacity were added — an 80 percent and 110 percent increase over the previous monthly records, respectively.

These additions outpaced even the rapid demand growth, displacing coal and gas in the power mix. According to Carbon Brief, the result was a 5.8 percent decline in power-sector CO₂ emissions. Nuclear energy and biomass also contributed to the shift, while hydropower output remained stable, avoiding the usual year-to-year swings driven by rainfall.

Meanwhile, coal-fired power plants became more efficient. The amount of coal needed per unit of electricity fell by nearly 1 percent compared to last year, further reducing emissions.

Industrial Growth Offsets Gains Outside Power Sector

Despite progress in electricity generation, emissions outside the power sector tell a more complex story. Industries like metals and chemicals posted increases, with coal use in these sectors growing steadily. The coal-to-chemicals sector, in particular, saw significant expansion during the first quarter of 2025, driven by fears of dependency on imported oil and gas, as well as favorable market conditions created by lower coal prices and higher oil costs.

Crude steel production edged up by 0.6 percent, while non-ferrous metals rose by 2 percent. Much of this growth occurred in March, fueled by a burst of export orders ahead of the expiration of a 90-day reprieve in tariffs imposed by the United States. Real estate, by contrast, showed continued weakness. Construction starts fell by 24 percent and new home sales dropped 3 percent, continuing a trend that has softened demand for cement and other building materials.

In the transportation and machinery sectors, output jumped 12 to 13 percent, reflecting domestic investment and a temporary surge in demand. Yet oil product consumption has declined 2 percent since peaking after the pandemic rebound, pointing to longer-term changes in fuel use.

Policy Shake-up Adds Momentum—And Uncertainty

June will see the introduction of a new renewable energy pricing policy that removes guaranteed rates previously tied to coal power prices. Instead, solar and wind projects will now have to secure contracts directly with buyers. The move has already triggered a wave of new installations, as developers race to complete projects under the old regime.

The China Electricity Council forecasts that wind additions could reach as high as 130 gigawatts this year, with solar capacity expected to remain near last year’s historic high of 278 gigawatts. Industry projections suggest a temporary slowdown in installations later this year, especially in distributed solar, due to the pricing shift. Still, large-scale projects under central government oversight are likely to proceed.

Provinces have significant discretion in how they implement the new rules. Given the economic weight of the renewables industry in many regions, local governments may work to minimize disruptions. Central government targets will also play a critical role. The National Energy Administration currently aims for more than 200 gigawatts of new clean energy capacity per year—well below the 360 gigawatts added in 2024—raising questions about the pace of future expansion.

Emissions Future Hinges on Next Five-Year Plan

Whether this decline in emissions will continue depends largely on decisions still to be made. China’s next five-year plan, expected in 2026, will set new energy and climate targets. Analysts say these will be decisive in determining whether emissions can enter a sustained structural decline.

In the short term, the economic response to U.S. tariffs is shaping energy demand. The Chinese government has signaled a desire to shift from export-driven growth to domestic consumption, a strategy that could reduce the energy intensity of GDP. In April, People’s Daily, the Communist Party’s main newspaper, called for “consumption to become the main driving force and ballast stone of economic growth,” suggesting broader support for this transition.

Recent stimulus measures have already bolstered industries such as shipbuilding and infrastructure. But to maintain emissions reductions, analysts say China must steer clear of previous patterns of construction-heavy stimulus and instead invest in cleaner technologies and domestic services.

Even so, official data shows that emissions are only about 1 percent below their previous peak, leaving room for a rebound. The coal-to-chemicals sector remains a wild card, with potential for further growth despite price pressures and uncertain demand. The direction China takes in the next two years could determine whether this year’s decline becomes the beginning of a broader shift — or just a pause in a longer climb.
