Core Points - Chengdu's Wenjiang District and Qingbaijiang District have signed a bulk exchange agreement for major air pollutant emission quotas, marking the first cross-regional quota exchange case in the province [1] - The innovative exchange breaks down resource allocation barriers between districts, allowing for the effective use of limited emission quotas to support various construction projects with a total investment exceeding 30 billion yuan in Wenjiang and approximately 150 billion yuan in Qingbaijiang [1] - The exchange is facilitated by the recent implementation of the "Regulations on the Review and Management of Major Air Pollutant Emission Quotas for Construction Projects" by Chengdu's Ecological Environment Bureau, which aims to balance project implementation and air quality improvement [1] Emission Reduction Goals - Chengdu has exceeded its "14th Five-Year Plan" emission reduction targets by the end of 2024, addressing the shortage of nitrogen oxide quotas through policy support and the development of a technical guide for emission reduction accounting [2] - The city plans to expand the scope of emission reduction projects to include reductions from industrial and automotive repair sectors, potentially adding 238 tons of nitrogen oxides and 254 tons of volatile organic compounds to the total quota [2] - The approval process for construction project environmental assessments will emphasize accurate and objective accounting of quota replacements to minimize unnecessary "quota waste" [2]
