, 2018 驱动管理对象减少二氧化碳排放是碳排放权交易机制的一项重要功能。基于碳排放权交易机制的减排机理和倍差法原理构建碳排放权交易机制减排有效性评价方法,通过碳排放权配额总量松弛度计算、管理对象分别在对照期和实验期的相对减排率测算比较,建立起机制减排有效性充分必要条件的判断矩阵,对我国7个碳交易试点机制进行减排有效性的评价和分析,提炼出影响碳交易机制减排有效性的要素,为国家碳交易机制运行提供参考。研究表明:在管理对象具有减排潜力的情况下,如果配额总量供给低于碳排放需求,碳交易机制能有效地发挥促进减排的作用 ...

Unpacking value destruction at the intersection between public and private value
Public Administration, Volume 101, Issue 4, Page 1207-1226, December 2023., 2023 Abstract Public services do not always create value. Rather, when poorly organized and/or delivered, they can destroy value and make service users' lives worse. However, such “value destruction” is presently weakly conceptualized in public management theory. Consequently, this paper is devoted to the empirical examination of value destruction and hence

Retaining natural vegetation to safeguard biodiversity and humanity
Conservation Biology, Volume 37, Issue 3, June 2023., 2023 Abstract Global efforts to deliver internationally agreed goals to reduce carbon emissions, halt biodiversity loss, and retain essential ecosystem services have been poorly integrated. These goals rely in part on preserving natural (e.g., native, largely unmodified) and seminatural (e.g., low intensity or sustainable human use) forests, woodlands, and ...

Global Change Biology, Volume 28, Issue 18, Page 5416-5426, September 2022., 2022 Due to climate change, the breeding range of the two Asian subspecies of Black‐tailed Godwit would shift northward in the future, accompanied by a significant decline in suitable breeding range size. Abstract Habitat loss and shifts associated with climate change threaten global biodiversity, with impacts likely to be most pronounced at high latitudes.

Evident but context‐dependent mortality of fish passing hydroelectric turbines
Conservation Biology, Volume 36, Issue 3, June 2022., 2022 Abstract Globally, policies aiming for conservation of species, free‐flowing rivers, and promotion of hydroelectricity as renewable energy and as a means to decarbonize energy systems generate trade‐offs between protecting freshwater fauna and development of hydropower. Hydroelectric turbines put fish at risk of severe injury during passage. Therefore,

Review of Policy Research, Volume 38, Issue 5, Page 529-554, September 2021., 2021 Abstract Carbon taxes are frequently advocated as a means of reducing greenhouse gas (GHG) emissions, yet their political feasibility remains a challenge. To enhance their political appeal, carbon tax proponents have proposed revenue recycling as a means of alleviating public concern with this instrument's visible costs.

Rewilding in the face of climate change
Conservation Biology, Volume 35, Issue 1, Page 155-167, February 2021., 2021 Abstract Expansion of the global protected‐area network has been proposed as a strategy to address threats from accelerating climate change and species extinction. A key step in increasing the effectiveness of such expansion is understanding how novel threats to biodiversity from climate change alter concepts such as rewilding, which have underpinned ...

, 2016 碳税和碳交易机制是控制温室气体排放的环境管理工具,对工业行业的减排成本造成不同的影响。以污染控制政策的稳态总期望社会成本函数为基础构建碳减排成本函数,比较碳税和碳交易机制下水泥行业减排成本,发现影响两种环境管理工具成本的要素。以广东和山东水泥行业的实证数据进行模拟分析,得到如下结论：当碳价和碳税税率差距不大时,由于碳交易机制需要较高的建设成本,碳税更具成本优势;短期内,由于减排技术投入成本较高,与强制性的行政管理手段相比,碳交易机制更具成本效益;碳价、碳税税率、最佳可获得技术的价格、企业预期 ...

Gongye shui chuli, 2023 老龄生活垃圾填埋场渗滤液具有可生化性差、氨氮高以及C/N失调等特点，采用传统生化脱氮工艺需投加大量碳源，处理成本高且整体碳排放量大。为降低脱氮运行成本，实现减污降碳目标，以某老龄填埋场的渗滤液处理项目为例，采用精馏脱氮组合技术取代传统A/O+MBR工艺作为主要脱氮单元，同时通过沼气锅炉燃烧沼气产生蒸汽的方式为精馏脱氮单元提供热源，实现填埋气资源循环利用。基于IPCC排放因子法，以传统脱氮工艺碳排放量为基准线，对两种不同脱氮工艺碳排放特征进行分析。结果表明：A/O ...
