Global warming potential associated with Irish milk powder production

William Finnegan, Jamie Goggins, Aksana Chyzheuskaya, Xinmin Zhan

《环境科学与工程前沿（英文）》 2017年第11卷第3期 doi: 10.1007/s11783-017-0949-z

摘要： Climate change is an ever growing issue and a major concern worldwide. Both producers and processors need to address the issue now by reducing their carbon footprint. Additionally, if Ireland is to meet their climate and energy targets, as outlined in Food Harvest 2020, which outlines a range of objectives for the Irish agricultural sector, the efficient use of resources and fuels within the industry will need to be increased. In Ireland, agriculture accounts for 29.2% of the total greenhouse gas emissions (58.5 million tonnes CO eq). Therefore, in this paper, a single agri-food product, milk powder, is examined in order to estimate the global warming potential (GWP) associated with its manufacture using life cycle assessment. A cradle-to-processing factory gate analysis, which includes raw milk production, raw milk transportation to the processing factory, its processing into each product and product packaging, is assessed in this study using data collected circa 2013. The factories surveyed processed approximately 24% of the total raw milk processed in the Republic of Ireland in 2013, which was 5.83 billion liters. The average total GWP associated with the manufacture of milk powder is 9.731 kg CO eq·kg milk powder, which has a standard deviation of 2.26 kg CO eq·kg milk powder, for the life cycle stages analyzed in this study. The most significant contributor to GWP is raw milk production (84%), followed by dairy processing (14%), with the remainder of the life cycle stages contributing approximately 2%.

Impact of climate change on building heating energy consumption in Tianjin

Cao XIANG, Zhe TIAN

《能源前沿（英文）》 2013年第7卷第4期页码 518-524 doi: 10.1007/s11708-013-0261-y

摘要： This paper investigated the variation of building heating energy consumption caused by global warming in Tianjin, China. Based on the hourly historical and monthly projected future (B1/A1B emissions scenarios) meteorological data, the variation of those relevant meteorological parameters was first analyzed. A TRNSYS simulation model for a reference building was introduced to investigate historical variation of office building energy consumption. The results showed that the 10-year-average heating energy consumption of 2001–2010 had reduced by 16.1% compared to that of 1961–1970. By conducting principal component analysis and regression analysis, future variation of building heating load was studied. For B1/A1B emissions scenarios, the multi-year-average heating load was found to decrease by 9.7% (18.1%)/10.2% (22.7%) compared to that of 1971–2010 by 2011–2050 (2051–2100).

The relevance of James Lovelock’s research and philosophy to environmental science and academia

《环境科学与工程前沿（英文）》 2023年第17卷第3期 doi: 10.1007/s11783-023-1639-7

摘要： James E. Lovelock, famed for his Gaia hypothesis, which views the Earth as a living integrated and interconnected self-regulating system whose equilibrium comes about from complex energy-based interactions and feedback loops, ultimately sustaining life, passed away at the end of July, 2022 at the age of 103. Not only are the adaptive mechanisms of Gaia central to the conversation of environmental homeostasis, they lie at the heart of climate change and global warming. Lovelock is also remembered as the co-inventor of the electron capture detector that eventually allowed for the sensitive detection of chlorofluorocarbons and pesticides. Finally, Lovelock’s free-spirited nature and research independence allow academia to rethink current research’s modus operandi.

关于气候变化的哲学思考

李佩成

《中国工程科学》 2008年第10卷第11期页码 7-13

摘要：

从哲学的基本原理出发，引用地史及水文气象资料探讨了全球气候变化问题，指出全球气候一直在变化；气候变化的动力主要在天在地而不在人；当今的气候变化可能只是气候变化总过程中的一个波动阶段而非永远的趋势,且其变幅并未超出历史上气候变化的范畴。因此，不能断言全球气候变暖是由于人为排放CO₂所致。所以对于不同时空条件下的气候变化应当具体矛盾具体分析具体解决，进而提出了中国应对气候变化的对策建议。

Pilot-scale studies of domestic wastewater treatment by typical constructed wetlands and their greenhouse gas emissions

Chaoxiang LIU, Kaiqin XU, Ryuhei INAMORI, Yuhei INAMORI, Yoshitaka EBIE, Jie LIAO,

《环境科学与工程前沿（英文）》 2009年第3卷第4期页码 477-482 doi: 10.1007/s11783-009-0155-8

摘要： Three typical constructed wetlands (CWs) including Vertical Flow (VF), Free Water Surface (FWS), and Subsurface Flow (SF), and combined VF-SF-FWS constructed wetlands were investigated for the treatment of domestic wastewater with low C/N ratio. The performance of nutrient removal and the characteristics of greenhouse gas emissions, such as CH and NO, from these CWs were compared. The results indicated that the four types of CWs had high removal efficiencies for organic matter and suspended solid (SS). The combined wetland also showed a comparatively good performance for nitrogen and phosphorus removal, and the removal efficiencies for total nitrogen (TN) and total phosphorus (TP) were 81.3% and 84.5%, respectively. The combined CWs had a comparative lower global warming potential. The FWS CW had the highest tendency to emit CH and led to a higher global warming potential among the four types of CWs, which was about 586 mg CO/m·h.

Quantification of energy related industrial eco-efficiency of China

Jiansu MAO, Yanchun DU, Linyu XU, Yong ZENG

《环境科学与工程前沿（英文）》 2011年第5卷第4期页码 585-596 doi: 10.1007/s11783-010-0289-8

摘要： Improving eco-efficiency is propitious for saving resources and reducing emissions, and has become a popular route to sustainable development. We define two energy-related eco-efficiencies: energy efficiency (ENE) and greenhouse gas (GHG) emission-related eco-efficiency (GEE) using energy consumption and the associated GHG emissions as the environmental impacts. Using statistical data, we analyze China’s energy consumption and GHG emissions by industrial subsystem and sector, and estimate the ENE and GEE values for China in 2007 as 4.871×10 ?US$/PJ and 4.26×10 US$/TgCO eq, respectively. Industry is the primary contributing subsystem of China’s economy, contributing 45.2% to the total economic production, using 79.6% of the energy consumed, and generating 91.4% of the total GHG emissions. We distinguish the individual contributions of the 39 industrial sectors to the national economy, overall energy consumption, and GHG emissions, and estimate their energy-related eco-efficiencies. The results show that although ferrous metal production contributes only 3.5% to the national industrial economy, it consumes the most industrial energy (20% of total), contributes 16% to the total industrial global warming potential (GWP), and ranks third in GHG emissions. The power and heat sector ranks first in GHG emissions and contributes one-third of the total industrial GWP, although it only consumes about 8% of total industrial energy and, like ferrous metal production, contributes 3.5% to the national economy. The ENE of the ferrous metal and power and heat sectors are only 8 and 2.1×10 US$/PJ, while the GEE for these two sectors are 9 and 4×10 US$/GgCO eq, respectively; these are nearly the lowest ENE and GEE values among all 39 industry sectors. Finally, we discuss the possibility of eco-efficiency improvement through a comparison with other countries.

气候变暖背景下的极端天气气候事件与防灾减灾

翟盘茂,刘静

《中国工程科学》 2012年第14卷第9期页码 55-63

摘要：

首先概括极端天气气候事件以及“气候极值”的相关定义，并把极端事件分为单要素的极端事件、与天气现象有关的极端事件、多要素极端事件和极端气候事件。在此基础上，总结上述几类极端事件在气候变暖背景下的变化趋势及影响。指出气候变暖背景下我国长江中下游区域强降水事件更趋频繁，我国东部地区高温热浪天气更为明显；东北华北地区干旱趋势增加，尤其在20世纪末期和21世纪初期最为明显；近10年来西南地区干旱频繁发生。为减轻日益增加的重大气象灾害的损失，我国有必要加强高影响极端事件的监测、预警能力建设，同时还必须根据极端天气气候事件变化规律加强工程性防御措施，以防范和应对强降水引发的洪涝灾害和城市渍涝，以及与降水持续不足有关的重大干旱和高温热浪等气象灾害。

Greenhouse gas emissions from thermal treatment of non-recyclable municipal waste

Tomáš Ferdan, Martin Pavlas, Vlastimír Nevrlý, Radovan Šomplák, Petr Stehlík

《化学科学与工程前沿（英文）》 2018年第12卷第4期页码 815-831 doi: 10.1007/s11705-018-1761-4

摘要：

This paper analyses factors affecting the production of greenhouse gases from the treatment of residual municipal waste. The analysis is conducted so that the environmentally-friendly decision-making criteria may be later implemented into an optimisation task, which allocates waste treatment capacities. A simplified method of life cycle assessment is applied to describe environmental impact of the allocation. Global warming potential (GWP) is employed as a unit to quantify greenhouse gases (GHG) emissions. The objective is to identify the environmental burdens and credits measured by GWP for the three fundamental methods for treatment of residual waste unsuitable for material recovery. The three methods are waste-to-energy (WTE), landfilling and mechanical-biological treatment (MBT) with subsequent utilization of refuse-derived fuel. The composition of the waste itself and content of fossil-derived carbon and biogenic carbon are important parameters to identify amounts of GHG. In case of WTE, subsequent use of the energy, e.g., in district heating systems in case of heat, is another important parameter to be considered. GWP function dependant on WTE capacity is introduced. The conclusion of this paper provides an assessment of the potential benefits of the results in optimisation tasks for the planning of overall strategy in waste management.

Mass loss and nutrient dynamics during litter decomposition in response to warming and nitrogen addition

Haiyan REN, Jie QIN, Baolong YAN, Alata, Baoyinhexige, Guodong HAN

《农业科学与工程前沿（英文）》 2018年第5卷第1期页码 64-70 doi: 10.15302/J-FASE-2017194

摘要： Plant litter decomposition has been studied extensively in the context of both warming and increased atmospheric nitrogen deposition. However, the temporal patterns of mass loss and nutrient release in response to warming and nitrogen addition remain unclear. A 2-year decomposition experiment aimed to examine the effects of warming and nitrogen addition on decomposition rate, and nitrogen and phosphorus dynamics. The effects of warming and nitrogen addition on decomposition of litter of , a dominant species in a desert steppe of northern China, were studied. Warming and nitrogen addition significantly enhanced litter mass loss by 10% and 16%, respectively, and moreover promoted nitrogen and phosphorus release from the litter in the first year of decomposition, followed by an immobilization period. The interactive effects of warming and nitrogen addition on mass loss, nitrogen and phosphorus concentrations of litter were also found during the decomposition. This study indicates that warming and nitrogen addition increased litter mass loss through altering litter quality. These findings highlight that interactions between climate change and other global change factors could be highly important in driving decomposition responses.

气候变暖加剧西藏自治区谷类作物单产的减产效应

斯确多吉, 朴世龙, 王旭辉, 赵闯, 刘保花, 陈安平, 汪诗平, 汪涛

《工程（英文）》 2022年第14卷第7期页码 163-168 doi: 10.1016/j.eng.2021.01.012

摘要：

藏区农业是西藏自治区独特的历史和文化遗产的重要载体。与内地不同，作为唯一能在海拔4000 m以上生长的谷类作物，青稞是西藏自治区最主要的粮食作物。然而，气候变化对以青稞为主的西藏自治区谷类作物单产的影响仍不清楚。为此，本研究基于1985—2015年西藏自治区农业统计数据，解析了气候变暖对西藏自治区谷类作物单产的影响。研究发现，在20世纪80年代和90年代，气候变暖对西藏自治区谷类作物单产的影响并不显著（P > 0.10）；但21 世纪以来，气候变暖显著降低了西藏自治区谷类作物单产（P < 0.05）。同时，西藏自治区谷类作物单产变化对气候变暖的敏感度几乎加倍：从(−0.13 ± 0.20) t·ha⁻¹·^°C⁻¹增至(−0.22 ± 0.14) t·ha⁻¹·^°C⁻¹，表明气候变暖导致西藏自治区谷类作物生产更加脆弱。不仅如此，随着气温继续升高，当全球平均气温升幅比工业革命前高1.5 ^°C 和2 ^°C时，西藏自治区谷类作物单产对气候变暖的敏感度将比当前再增强1~2 倍，分别达到(−0.33 ± 0.10) t·ha⁻¹·^°C⁻¹和(−0.51 ± 0.18) t·ha⁻¹·^°C⁻¹。如何应对全球变化、实现农业可持续发展是当前西藏自治区社会发展面临的重大挑战。
