基于绿色可持续理念的污染场地修复碳足迹研究进展

Carbon Footprint on Remediation of Contaminated Sites Based on Concept of Green and Sustainability:A Review

污染场地修复工程,以其短期、在较小空间尺度内产生高强度的能源消耗和碳排放而受到广泛关注。在全球环境变化及“双碳”政策背景下,污染场地的绿色可持续修复成为必然趋势。降低污染场地修复工程的碳排放水平,可以为减缓气候变化、实现修复行业的绿色发展提供重要支撑。然而,目前我国污染场地修复行业仍存在碳足迹评估技术研究不充分、绿色可持续修复理念贯彻不深入等问题。本文梳理了污染场地绿色可持续修复的发展历程和存在问题,以修复行为的碳足迹核算为着力点,综述了基于绿色可持续修复理念的碳足迹核算研究进展与案例分析,从场地、区域和宏观的不同尺度层面探究了污染场地修复评估方法体系中碳核算相关工作。在气候变化的全球背景下和“双碳”政策的国家背景下,污染场地碳足迹核算将为我国修复行业实现减污降碳、推进绿色低碳管理提供参考。

Remediation projects on contaminated site have received extensive attention for their high-intensity energy consumption and carbon emissions at small spatial scales in short time.Under the background of global environmental changes and carbon peak and neutrality policy,the green and sustainable remediation of polluted sites has become an inevitable trend.Reducing carbon emission level from remediation projects of contaminated sites,it can provide important support for mitigating climate change and realizing the green development of the remediation industry.However,there are still problems such as insufficient research on assessment technologies of carbon footprint and in-depth implementation of the concept of green and sustainable restoration in Chinese polluted site remediation industry.This paper sorts out the development history and existing problems of green and sustainable remediation of polluted sites,focuses on carbon footprint accounting of remediation behaviour,summarizes the research progress and cases of carbon footprint accounting based on the concept of green and sustainable remediation,and explores the related work of carbon accounting in the assessment method system of contaminated site remediation from site,region and macro scales.In the global context of climate change and the national context of carbon peak and carbon neutrality policy,it provides a reference for Chinese remediation industry to reduce pollution and carbon,and promote green and low-carbon management.
