Burning stubble in the fields had been largely banned since 1999, but local governments are now allowing the practice in some circumstances.

The relaxation of China’s straw burning ban
Abatify Summary
Nature & Climate Perspective
The relaxation of the straw burning ban threatens regional air quality and reverses progress in soil organic carbon preservation and microbial health.
- Open-field combustion destroys topsoil microbiology and beneficial insect populations essential for natural nutrient cycling and pest management.
- Direct burning converts biomass that could have been sequestered as soil organic matter into immediate atmospheric CO2 and methane emissions, undermining LULUCF targets.
- The release of black carbon (soot) from stubble burning accelerates local warming and poses acute risks to atmospheric stability and human respiratory health.
Market & Policy Outlook
This policy shift complicates ICVCM Core Carbon Principles regarding 'Additionality' and 'Robust Quantification' by altering the regulatory baseline for agricultural carbon projects.
- The transition from a total ban to partial allowance shifts the legal baseline, potentially disqualifying new crop-residue-to-biochar projects from claiming high-integrity carbon credits.
- Market pricing for Chinese agricultural offsets may face a 'Permanence' discount as shifting local enforcement creates uncertainty regarding long-term biomass management strategies.
- Fluctuating domestic policies on biomass utilization may hinder China's ability to supply high-quality ITMOs under Article 6.2 if emission factors for the agricultural sector become volatile.
