Malaysia has implemented the Minimum Energy Performance Standards (MEPS) since 2013 to promote energy efficiency. This study collected sales data from 2013 to 2015 to estimate the sales volume of MEPS-compliant appliances (air conditioner, refrigerator, fan, television, and lamp), and subsequently determine the total electricity consumption and saving. It was found that the local market is already saturated with 5-star rated televisions and fans, while the lamp market is dominated by compact fluorescent lamps (CFL) with efficacy range of 50-55 lumens/W. By the end of 2015, the total cumulative electricity saving gained is 2,685 GWh, which translates to total cost saving of MYR 850 million and fossil carbon emission reduction of 1,726 ktCO2eq. These multiple positive impacts clearly demonstrate the effectiveness of MEPS in Malaysia. Hopefully, this success story would motivate Malaysia and other developing countries to unlock more opportunities in the future with higher uptake of energy efficiency interventions.
马来西亚自2013年起实施最低能源绩效标准(MEPS),以提高能源效率。本研究收集2013年至2015年的销售数据,估算符合meps标准的电器(空调、冰箱、风扇、电视、灯)的销量,进而确定总耗电量和节电。调查发现,本地市场的5星级电视和风扇已经饱和,而灯具市场则以50-55流明/瓦的紧凑型荧光灯(CFL)为主。截至2015年底,累计节电总量为2685吉瓦时,相当于节约总成本8.5亿林吉特,减少化石碳排放1726千吨二氧化碳当量。这些多重积极影响清楚地证明了马来西亚环境保护计划的有效性。希望这个成功的故事能够激励马来西亚和其他发展中国家在未来通过更多地采用能源效率干预措施来释放更多的机会。

The chemical manufacturing industry is one of the main contributors to the Malaysian economy and has been reported to have sustainability issues which may affect the sustainability of the nation if proper green practices have not been taken by the industry. This paper aims to study the effects of sustainable procurement on corporate sustainability performance with the moderating role of organisation age. Drawing data from 130 Malaysian chemical manufacturing organisations, the model studies the moderating role of organisation age on sustainable procurement and the corporate sustainability performance of the organisations. Partial least square (PLS) analysis is used in this study in order to analyse the data and the multistage sampling technique has also been used in this study. The results show that there is a positive relationship between sustainable procurement and corporate sustainability performance and organisation age does not moderate the effect of sustainable procurement on corporate sustainability performance.
化学制造业是马来西亚经济的主要贡献者之一,据报道,如果该行业没有采取适当的绿色做法,可能会影响国家的可持续性问题。本文旨在研究可持续采购在组织年龄的调节作用下对企业可持续发展绩效的影响。该模型从130个马来西亚化学制造组织中提取数据,研究组织年龄对可持续采购和组织的企业可持续发展绩效的调节作用。本研究采用偏最小二乘(PLS)分析方法对数据进行分析,并采用多阶段抽样技术。结果表明,可持续采购与企业可持续发展绩效之间存在正相关关系,组织年龄不影响可持续采购对企业可持续发展绩效的影响。

In this paper, we argue that the intellectual property (IP) management of publicly developed technology serves insufficiently the imperatives of climate change mitigation, which are understood to demand most efficient dissemination of environmentally sound technology (EST), and its development. Firstly, we outline some of the criticism of IPR for climate change mitigation. Then we explain the crucial role of public funding for EST by discussing economic theory of innovation based on the writings of Joseph Schumpeter and Mariana Mazzucato, and focus on the way in which the intellectual property rights (IPRs) of publicly funded EST have been managed in the most important areas of state innovation: public procurement for innovation (PPFI), the EU Pilot Horizon 2020 and university research. We outline the perceived problems with IP management of EST and where possible try to outline changes which could, in our view, provide a viable alternative to often proposed changes to the global IP regime in regard to climate change.
在本文中,我们认为,公共开发技术的知识产权(IP)管理不足以满足减缓气候变化的需要,这被理解为要求最有效地传播无害环境技术(EST)及其发展。首先,我们概述了对知识产权在减缓气候变化方面的一些批评。然后,我们通过讨论Joseph Schumpeter和Mariana Mazzucato的著作为基础的创新经济理论来解释公共资助对科技的关键作用,并重点关注公共资助的科技的知识产权(ipr)在国家创新的最重要领域的管理方式:公共采购创新(PPFI),欧盟试点地平线2020和大学研究。我们概述了环境科学技术知识产权管理方面存在的问题,并在可能的情况下试图概述我们认为可以为气候变化方面经常提出的全球知识产权制度变化提供可行替代方案的变化。

The manufacturing sector faces sustainability issues which lead to negative consequences to the economic, environment and social sustainability performance of the sector. Cleaner production and resource efficiency which involve the use of green technology is one of the important green practices in achieving corporate sustainability performance. The objective of this study is to examine the effects of cleaner production and resource efficiency on corporate sustainability performance with the moderating role of organisational size. Drawing data from 130 Malaysian chemical manufacturing organisations, the model studies the moderating role of organisation size on cleaner production and resource efficiency and corporate sustainable performance of the organisations. The data are analysed using partial least square (PLS) analysis. The results suggest that cleaner production and resource efficiency are positively related to corporate sustainability performance. The findings also indicate that organisation size moderates the effect of cleaner production and resource efficiency on corporate sustainability performance.

Malaysia aims to reduce CO2 emissions intensity by up to 45% by 2030 based on its 2005 levels. This paper presents an analysis on optimal CO2 emissions reduction in Malaysian road transport sector using a linear programming CO2 minimisation model. Sensitivity analysis was also applied to investigate the effects of mitigation measures such as low carbon fuels, fuel efficiency improvement, travel demand management, and integrated mitigation strategies on CO2 emissions. The results demonstrated that the optimal CO2 emissions in the road transport sector could be reduced by only 2.8% (1.14 Mtons CO2) in a year. However, a reduction of up to 40% (16.44 Mtons CO2) could be achieved if integrated mitigation measures were implemented. Moving forward, Malaysia should intensify the ongoing efforts and promote fuel efficiency and green investment to achieve the intended CO2 emissions reduction.
马来西亚的目标是到2030年将二氧化碳排放强度在2005年的基础上降低45%。本文提出了对马来西亚道路运输部门使用线性规划二氧化碳最小化模型的最佳二氧化碳减排分析。敏感性分析还用于调查诸如低碳燃料、提高燃油效率、旅行需求管理和综合缓解战略等缓解措施对二氧化碳排放的影响。结果表明,道路运输部门的最佳二氧化碳排放量每年只能减少2.8%(114万吨二氧化碳)。然而,如果实施综合缓解措施,最多可减少40%(1644万吨二氧化碳)。展望未来,马来西亚应加强正在进行的努力,提高燃油效率和绿色投资,以实现预期的二氧化碳减排目标。

This study aims to measure the corporate environmental reporting (CER) practices of Malaysian environmentally sensitive public listed companies based on measurement approach named strategically-framed environmental disclosure index. The content analysis technique based on a measurement index related to firm's environmental strategies has been employed. The CER practices of 209 Malaysian environmentally sensitive public listed companies are examined for the years 2010 and 2014. Results suggest that there are three types of firm behaviour in CER in response to institutional pressures: 1) 'negative deviance' (i.e., non-compliance environmental strategies leading to no quality environmental disclosures); 2) 'conformance' (i.e., compliance environmental strategies leading to low quality environmental disclosures); 3) 'positive deviance' (beyond-compliance or proactive environmental strategies leading to high quality environmental disclosures). This index shed light whether the environmental, social and governance (ESG) practice in Malaysian and global context as a deviance or normative behaviour. Moreover, this study identified whether mandatory reporting requirement force firm to actually improve environmental performance concurrently with pro-environmental policies or just as their greenwashing mechanism.
本研究旨在基于战略框架环境披露指数的测量方法来衡量马来西亚环境敏感型上市公司的企业环境报告(CER)实践。本文采用了基于与企业环境战略相关的测量指标的内容分析技术。本文考察了2010年和2014年马来西亚209家环境敏感上市公司的CER实践。研究结果表明,在应对制度压力时,CER中的企业行为有三种类型:“负面偏差”(即,不符合环境策略导致没有高质量的环境披露);2) “合规性”(即合规性环境策略导致低质量的环境披露);3)“积极偏差”(超越合规或主动环境策略,导致高质量的环境披露)。该指数阐明了马来西亚和全球背景下的环境,社会和治理(ESG)实践是一种偏差还是规范行为。此外,本研究还确定了强制性报告要求是否迫使企业在实施亲环境政策的同时实际改善环境绩效,还是仅仅作为其绿色清洗机制。

Several epidemiological studies have found associations between turbidity in drinking water supplies and acute gastrointestinal illness, although these results have been controversial. This project sought to critically evaluate these epidemiological studies through a workshop of multidisciplinary subject matter experts. Pre- and post-workshop surveys were conducted to assess any changes in opinion occurring after the one-day workshop where issues identified in the literature review were discussed. Changes were mostly small, non-significant shifts toward less favourable views of the studies. The only significant change was a shift weak agreement to weak disagreement with the statement that more should be done to ensure US drinking water quality. Responses to questions differed significantly by affiliation, discipline, and by role in the study. The survey results indicate that the workshop did not produce consensus among the participants. The survey provided a means of documenting differences in opinions expressed by all workshop attendees.
几项流行病学研究发现,饮用水供应中的浊度与急性胃肠道疾病之间存在关联,尽管这些结果一直存在争议。该项目试图通过多学科主题专家研讨会对这些流行病学研究进行批判性评估。进行了研讨会前和研讨会后的调查,以评估在为期一天的研讨会后意见的任何变化,在研讨会上讨论了文献综述中发现的问题。变化大多是微小的、不显著的、向不太有利的研究观点转变。唯一的重大变化是,对应该采取更多措施确保美国饮用水质量的声明,从微弱的同意转变为微弱的不同意。对问题的回答因隶属关系、学科和在研究中的角色而存在显著差异。调查结果表明,研讨会没有在与会者中达成共识。该调查提供了一种记录所有研讨会与会者意见差异的方法。

This study aims to investigate total coliform (TC) and thermotolerant coliform (TTC) removal efficiency of the waste stabilisation ponds (WSPs) system in Central India through the dispersed flow regime. To accomplish this, coliform (TC and TTC) die-off coefficient (Kb) was estimated for each pond (anaerobic, facultative and maturation) by the dispersed flow regime. Maximum Kb value was observed for the maturation pond (Kb, 5.8) in comparison to the facultative (Kb, 5.6) and anaerobic ponds (Kb, 1.8) and satisfactory correlate with the pond's depth (R2, 0.99) and hydraulic detention time (HDT) (R2, 0.73). On comparing coliform (TC and TTC) removal efficiency of different ponds in different seasons (viz; post monsoon, winter and summer), it was observed that total and thermotolerant coliform load increased in the post monsoon season. This was attributed to differences in the prevalence of infection and fecal excretion levels and due to the mixing of runaway water with raw sewage during the monsoon, which increased the bacterial load. Applying the dispersed flow model to assay coliform removal efficiency of WSPs system, we concluded that shallow ponds with a higher hydraulic detention time have good removal efficiency compared to deep ponds with lower hydraulic detention time.
本研究旨在通过分散流态研究印度中部废物稳定池(WSPs)系统的总大肠菌群(TC)和耐热大肠菌群的去除效率。为了实现这一点,通过分散的流动状态来估计每个池塘(厌氧、兼性和成熟)的大肠菌群(TC和TTC)死亡系数(Kb)。与兼性池(Kb,5.6)和厌氧池(Kb,1.8)相比,成熟池的Kb值最大,为5.8,并且与池的深度(R2,0.99)和水力滞留时间(HDT)(R2,0.73)具有令人满意的相关性。在比较不同季节(即季风后、冬季和夏季)不同池的大肠菌群(TC和TTC)去除效率时,观察到总大肠菌群和耐热大肠菌群负荷在后季风季节增加。这归因于感染率和粪便排泄水平的差异,以及季风期间失控的水与未经处理的污水混合,增加了细菌负荷。应用分散流模型对WSPs系统的大肠菌群去除效率进行了测定,得出的结论是,与水力滞留时间较低的深池相比,水力滞留时间较高的浅池具有良好的去除效率。

Applying the dispersed flow model to assay coliform removal efficiency of WSPs system, we concluded that shallow ponds with a higher hydraulic detention time have good removal efficiency compared to deep ponds with lower hydraulic detention time.","PeriodicalId":13984,"journal":{"name":"International Journal of Environmental Technology and Management","volume":"21 1","pages":"64-76"},"PeriodicalIF":0.6,"publicationDate":"2018-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49604266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a consumption-based method accounting for greenhouse gas emissions at regional level based on a multi-region input-output model. The method is based on regional consumption and includes imports and exports of emissions, factual emission developments, green investments as well as low carbon development policies. We comparatively analyse three regional case studies in Denmark and show how regional initiatives implemented to reduce emissions are translated into easy to access input-output parameter changes and how the method transparently assesses the impact of various long-term regional climate plans on emissions. For the comparative analysis we further develop a carbon regional index (CRI), which delineates five key dimensions that define past, current and planned regional and embedded emissions. The method can form a basis for regional climate policies, promote the export of solutions from one region to another and enable policy-makers to observe good practices and test them at regional level before potential implementation on a larger scale.
本文基于多区域投入产出模型,提出了一种基于消费的区域温室气体排放核算方法。该方法基于区域消费,包括排放进出口、实际排放发展、绿色投资以及低碳发展政策。我们比较分析了丹麦的三个区域案例研究,展示了为减少排放而实施的区域举措如何转化为易于获取的投入产出参数变化,以及该方法如何透明地评估各种长期区域气候计划对排放的影响。为了进行比较分析,我们进一步制定了碳区域指数(CRI),该指数描绘了五个关键维度,定义了过去、当前和计划的区域和嵌入排放。该方法可以成为区域气候政策的基础,促进解决方案从一个区域出口到另一个区域,并使决策者能够观察良好做法,并在区域一级对其进行测试,然后再进行更大规模的实施。

The present paper presents a review of vehicular pollution dispersion models with particular focus on CALINE4 model. The CALINE4 model is one of the most extensively used model for prediction of vehicular pollution along highways/roads. The CALINE4 model is easy handing and less input data requirement makes it useful for screening purposes. The paper also briefly discusses about the performance evaluation, sensitivity analysis of CALINE4 model along with uncertainty due to limitations in terms of input data provided in CALINE4 model's output.
本文综述了车辆污染扩散模型,特别是CALINE4模型。CALINE4模型是用于预测公路/道路沿线车辆污染的最广泛使用的模型之一。CALINE4模型易于处理,输入数据要求较少,可用于筛选目的。本文还简要讨论了CALINE4模型的性能评估、灵敏度分析以及由于CALINE4模式输出中提供的输入数据的限制而产生的不确定性。
