China's CO2 Emissions: World's Largest Emitter at 28% of Global Total

As of 2023–2024 data, China is the world's largest CO₂ emitter, releasing approximately 12–13 gigatonnes (Gt) annually — roughly 28–31% of global fossil fuel emissions.

Emissions Trajectory

• 1990: ~2.5 Gt (11% global)
• 2005: ~6 Gt (surpasses US)
• 2013: ~10 Gt (peak coal year)
• 2020: ~10.7 Gt (pandemic dip)
• 2023: ~12.5 Gt (rebound + growth)

Key Drivers

• Coal dependence: ~55% of energy, ~60% of electricity. 1,100+ GW coal capacity (half global total). New plants still permitting.
• Industrial dominance: Steel (53% world), cement (55%), aluminum (57%) — all coal-intensive
• Export manufacturing: 15–20% of emissions embedded in exports (consumption-based accounting lowers China's share)
• Urbanization & infrastructure: Construction, transport, appliances

Mitigation Efforts (Real & Significant)

• Renewables leadership: #1 in solar, wind, hydro, EV, battery production & deployment. 2023: +300 GW solar/wind (50%+ global additions)
• Targets: Peak CO₂ before 2030, carbon neutrality before 2060 (Xi 2020)
• ETS: National carbon market launched 2021 (power sector first; expanding)
• Coal policy: "Strict control" 2021–2025, "phase down" 2026–2030. But energy security fears drive continued approvals.
• Efficiency: Energy intensity -20% (2015–2020). Industrial upgrading.

Why Emissions Still Rising

• Energy demand growth > clean energy additions
• Coal as "ballast" for intermittent renewables + heat waves/droughts (hydro loss)
• Steel/cement decarbonization nascent (hydrogen, CCS pilot scale only)
• Property/infrastructure stimulus cycles

Global Context

• Per capita: ~8.5 tCO₂ (China) vs. ~14.5 (US), ~16 (Australia), ~4.5 (global avg)
• Historical (1850–2022): US 17%, China 13%, EU 11% — cumulative responsibility differs
• Consumption-based: China ~10 Gt (net exporter of embodied carbon)

China's emissions trajectory is the single largest factor in whether Paris Agreement goals (1.5°C/2°C) are achievable. Peak before 2030 is plausible; rapid decline after requires unprecedented coal retirement and industrial transformation.
