China’s emissions set to fall 17% by 2030, outpacing its climate pledge

TL;DR China’s emissions are projected to fall 17% below the 2023 peak by 2030, ahead of its own pledge, while the 1.5°C goal is deemed unattainable under today’s trajectory.

BloombergNEF’s New Energy Outlook 2026 uses a central modelling scenario that tracks energy supply, demand, and technology costs to forecast emissions through 2050. The model assumes current policies continue, incorporates falling renewable prices, and factors in recent energy shocks such as the pandemic and the war in Ukraine. It quantifies outcomes in percentages, temperature rise, and investment needs.

The report finds China’s greenhouse‑gas emissions will be 17% lower in 2030 than they were in 2023, even as the economy grows about 5% annually. This pace exceeds Beijing’s official commitment to peak carbon before 2030 and reach net zero before 2060. By 2050, emissions are expected to be half the 2023 peak level, though they will still remain above projected U.S. and European levels.

BloombergNEF also concludes that keeping global warming to 1.5°C is no longer feasible under existing trends; its maximum‑effort pathway now peaks at 1.81°C, up from 1.75°C in the previous edition. David Hostert, chief economist at BloombergNEF, noted that despite ongoing crises, countries have viable, lower‑cost technologies to respond.

The faster‑than‑expected decline in China’s output could ease pressure on global carbon budgets, but the upward revision of the warming ceiling signals that stronger action is still needed elsewhere. Analysts will watch whether China’s renewable rollout accelerates further and whether other major emitters adjust their targets in light of the 1.5°C assessment.
