大数据, 2023 作为算力承接地，西部地区拥有丰厚的自然资源禀赋，需充分发挥其在能源、气候等方面的优势。“东数西算”背景下，数据中心急需对算力转移过程的碳减排效益进行量化分析。在考虑可再生能源、气候因素和传输过程3个影响因素的情况下，构建了数据中心工作负载转移的碳排放量核算模型，以“东数西算”八大节点为例进行算例分析。结果发现，相较于可再生能源和气候因素所减少的碳排放量，传输过程造成的额外碳排放量微乎其微，在仅考虑前两者的情况下，每转移1 kW·h的工作负载，碳排放量可减少0.053~0.344 kg ...

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 ...

Zhongguo youzhi, 2023 为促进我国油脂加工行业碳排放认证，介绍了现有碳排放的计算方法、标准和数据库，对我国油脂加工行业减排案例及碳排放的认证现状进行了论述，探讨了碳排放计算和认证中存在的问题，并对油脂加工企业碳排放认证提出建议。我国油脂行业碳排放认证存在缺乏统一标准规范、提出的减碳方案空泛、认证计算不全面等问题，应制定油脂加工行业碳足迹计算标准规范，统一基础数据，建立数据库和碳足迹认证参数体系，以找到降低碳排放的关键环节，从而实现碳中和。 In order to promote the carbon emission ...

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 ...

Zhejiang Daxue xuebao. Lixue ban, 2012 基于我国碳排放约束性指标的提出，在收集2000〜2009年西部、中部、东北部及东部地区所辖30个省市（除西藏外）的相关数据的基础上，估算CO2排放情况，通过图表及有关参数分析这些区域CO2排放现状，阐明CO2排放特征.结果显示，近10年，我国单位GDP CO2排放量下降了 38. 4%，若兑现2020年碳减排承诺，减排量相当于2005年全球CO2排放量的29.
