从"无形"到"有价":节水量碳交易路径初探
From"intangible"to"valuable":a preliminary exploration of the water-saving volume carbon trading pathway
摘要
Abstract
Advancing carbon peaking in a well-placed and steady manner is a major task for China's economic and social development during the 15th Five-Year Plan period.Water serves as an important carrier of carbon.Water conservation is not only a core measure for ensuring water security,but also a crucial pathway for achieving carbon emission reductions.Currently,China's efforts to synergize water conservation and carbon reduction face several challenges,including an unclear understanding of the underlying mechanisms,an incomplete quantification system,and an underdeveloped market value for water-saving benefits.This paper systematically investigates the water conservation-carbon reduction synergy mechanisms,examines the relevance of carbon market instruments to water conservation,and explores the potential and pathways for incorporating the carbon reduction value generated by water saving into different carbon markets.The results show that water conservation delivers tangible carbon emission reductions through three synergistic mechanisms,including the water-energy-carbon nexus,the water-waste-carbon nexus,and the water-soil-carbon nexus,thus producing typical ecological benefits in carbon mission reductions.Once water savings are converted into verifiable carbon emission reductions based on these synergy mechanisms,they can be integrated into the carbon market system via the national carbon emission trading market,the national trading market for voluntary greenhouse gas emission reduction,and local carbon inclusive trading schemes.In addition,a comprehensive safeguard framework covering five dimensions—policy,technology,market,implementation,and capacity building—is required to transform the"intangible"ecological benefits of water-saving carbon reduction into"valuable"market assets.This work provides a theoretical foundation and practical direction for synergistically achieving intensive water resource conservation and utilization and the"dual carbon"goals,and offers a feasibility reference for establishing a novel value realization and investment mechanism for water conservation.关键词
