Structural shifts in China’s oil and gas CH4 emissions with implications for mitigation efforts

Trends and drivers of CH₄ emissions 1990–2022

China’s CH₄ emissions from the oil and gas systems increased by about 7 times from 0.5[0.5–0.6] TgCH₄ yr⁻¹ in 1990 to 4.0[3.7–4.4] TgCH₄ yr⁻¹ in 2022 (Fig. 1a), with an average annual…
