Evaluating coal bed methane investment in China based on a real options model

In this paper, a real options based binominal lattices model for the investment of coal bed methane (CBM) is conducted. CBM prices and market demand are incorporated into the model as the predominant uncertain factors and it is solved by using the bidimensional binominal lattices approach. Then the model is employed to evaluate the investment in CBM projects in China, and the effect of related policies is analyzed. The empirical results demonstrate that the model can be used to offer a better explanation of why the CBM industry has developed slowly in China from an investment perspective. It is found that the current policy environment is not positive enough to attract investment in the CBM industry. Among various factors, CBM prices yield the most significant effect on stimulating investment in CBM development. Increasing the price subsidy is also an effective policy to stimulate investment and promote the development of the CBM industry in China.     

Local Transport Problems and Possible Solutions: comparing perceptions of residents, elected members, officers and organisations

It is generally accepted that the current growth in personal car use poses a serious threat to local communities and the environment, and that radical changes in transport policy are needed. In order for local authorities to develop acceptable sustainable transport options, it will be necessary that they have a clear view of the attitudes and perceptions of various groups in their community. This research compared the views of elected members and officers with those of residents and organisations in relation to the local transport situation and the use of car travel reduction measures. It was found that the views of elected members and officers reflect those of residents rather well. The views of local organisations, however, were different. Organisations were, in particular, more negative about policy measures that aim to reduce car use in the town centre. They also attached more importance to the viability of the local economy than the other respondents. However, they did agree with the other groups that the quality of life in the community would improve if there was less traffic. The consequences of these findings for local transport planning are discussed.     

Use of recycled natural fibres in industrial products: A comparative LCA case study on acoustic components in the Brazilian automotive sector

This paper summarizes the results and the lessons learnt from an LCA case study comparing acoustic automotive components. Three alternative acoustic components produced by the Brazilian automotive sector are considered: dual-layer polyurethane (DL-PU) panel, recycled textile absorption-barrier-absorption (ABA-cotton) panel and recycled textile DL (DL-cotton) panel. DL-PU is a “status-quo” alternative, composed mainly of synthetic plastics and the two other alternatives are mainly made of recycled cotton fibres. Using the Life Cycle Assessment (LCA) method, the three following phases of the panels’ life cycle are examined: production, use and end-of-life. For the latter, two end-of-life scenarios are analysed: landfill and incineration with energy recovery. For the LCA model, some Life Cycle Inventory (LCI) datasets have been adapted from the data available in the EcoInvent database in order to adjust to the Brazilian context. LCA results show that, within the entire life cycle, the DL-cotton option, which combines two layers of recycled fibres of different densities, is overall the best alternative from an environmental perspective. This result is therefore independent from the end-of-life scenario. This is mainly due to the lower weight of this component, which is extremely important for the transportation aspects, but also due to its lower consumption of fossil resources, to the energy saving during its production and to the avoidance of textile disposal that would happen otherwise. The obtained results confirm the available literature dealing with the use of renewable fibres in industrial products. The particular behaviour of recycled fibres compared to virgin ones (in terms of shared contribution of agricultural production and of avoidance of landfilling) is highlighted in this paper, thanks to the application of the “50/50” allocation rule. LCA results are discussed in terms of their potential use in an R&D context. Further research needs are also derived from the case study, including the potential benefits of developing multi-objective optimization methods that include environmental impact to be used in the design of such a component.

Compromising sustainable mobility? The case of the Gothenburg congestion tax

Congestion charging is widely considered an effective policy measure to regulate and reduce car traffic demand and associated environmental and health problems in cities. However, introducing restrictive measures to constrain individual choice and behaviour for the common good has often proven difficult. Using a specific case, the Gothenburg congestion tax introduced in 2013, we study the policy process behind the introduction of the tax and assess to what extent green values were compromised along the way. The tax was made possible by co-financing infrastructure investments, including roads, which seemingly contradicts stated goals of reducing car traffic and emissions. We show how the tax was ‘muddled through’ in a top-down political compromise by a grand coalition where different interests could legitimate their support in relation to the achievement of partially conflicting objectives and projects. However, to declare the regulatory goals fully neutralised would be to underestimate the scheme's direct environmental effects and restrictive potential. Finding a compromise with powerful political and economic interests was necessary to get it off the ground. Once launched, however, it can over time regain its restrictive properties and lead to more profound long-term effects.     

The UK national obsession with energy supply

Whilst the European Union is proposing a Directive on integrated resource planning and leading cities in both Europe and America are investing in demand side measures, the UK electricity industry seems to be obsessed with building more supply capacity. Recent developments in Leicestershire emphasise this obsession with energy supply.

There is an alternative and local government should be vigorously pursuing this by both a close liaison with local utilities and by increasing public awareness of the social, economic and environmental benefits of reducing energy demand and providing energy services.     

CO2 emissions in calcium carbide industry: An analysis of China's mitigation potential

China's calcium carbide output has dominated the global market for several years, driven by the demand for PVC (polyvinyl chloride), a fundamental polymer material and also the primary downstream product of calcium carbide in China. The fast growth of this energy-intensive industry leads to an inevitable increase in CO₂ emissions. However, there is a large reduction potential with process improvement in this industry which is currently characterized by widespread outdated facilities. In this study, we attempt to assess the reduction potential of CO₂ emissions in China's calcium carbide production, based on the analysis of CO₂ emission patterns and estimation of the emission amount. Three scenarios regarding process improvement are employed to conduct this assessment. The results imply that the cumulative CO₂ abatement in the Current Policy Scenario and in the Strengthened Policy Scenario from 2008 to 2020, compared with the Baseline Scenario, are 89.0 and 107.6 million t, respectively. The specific measures and policy implications to achieve this potential are also discussed in the article.     

The UK national obsession with energy supply

Summary

Whilst the European Union is proposing a Directive on integrated resource planning and leading cities in both Europe and America are investing in demand side measures, the UK electricity industry seems to be obsessed with building more supply capacity. Recent developments in Leicestershire emphasise this obsession with energy supply.

There is an alternative and local government should be vigorously pursuing this by both a close liaison with local utilities and by increasing public awareness of the social, economic and environmental benefits of reducing energy demand and providing energy services.     

The acceptability, personal outcome expectations, and expected effects of transport pricing policies

Acceptability and personal outcome expectations (i.e., the extent to which one expects to be better or worse off) of transport pricing policies were examined in relation to the expected effects of these policies on one’s own car use, congestion and environmental problems. Car users who commuted frequently by car and experienced congestion on a regular basis evaluated two pricing measures, which were mainly aimed at either decreasing congestion (by tolling at congested areas) or environmental problems (by a differential kilometre charge based on car mass). For the policy mainly aimed to reduce congestion, acceptability was higher and personal outcome expectations were more positive when respondents expected reductions in congestion when the policy was implemented. The policy aimed to reduce environmental problems was more acceptable and respondents expected to be better off in general when they expected reductions in environmental problems after its implementation. Expectations, both about a decrease in congestion and environmental problems were related to respondents’ personal outcome expectations of the policy mainly aimed to decrease environmental problems. We conclude that the acceptability of transport pricing policies are not necessarily low because car users expect negative effects on their car use, but rather because they are not be convinced that transport pricing policies will reduce congestion and environmental problems.     

The effectiveness of soft transport policy measures: A critical assessment and meta-analysis of empirical evidence

In the last few years there has been a growing interest in transport policy concerning behaviour oriented ‘soft’ measures to reduce private car use. Besides an assessment of the methodological quality of available evaluation results, the present paper focuses on a quantitative, meta-analytical synthesis of this empirical evidence. For these purposes a data set of 141 studies evaluating three types of soft transport policy measures was compiled mainly from already published narrative research reviews. The ability to draw strong causal inferences from the available research evidence is limited by the fact that all the retrieved evaluation studies use weak quasi-experimental designs. At least for one policy measure type our analyses also indicate the presence of a reporting bias. Across all three soft policy measures we found a statistically significant random-effects pooled effect size of 0.15. Translated into the original metric such an effect size indicates an increase in the no-car use proportion from 39% to 46%.     

Wider roads, more cars

The transport policy currently followed in many European cities seems to be a combination of investments in public transport in order to increase, or at least maintain, its market share, and road building in order to keep up with expected traffic growth. Apparently, there is a prevalent belief among policy makers that increased road capacity in urban areas does not in itself cause any growth in car traffic worth mentioning. Such a belief neglects the simple economic theory of supply and demand, as well as more specific theories about the dynamics of traffic under congested conditions. An empirical study of commuting patterns in two transport corridors in Oslo, Norway, shows that a considerable proportion of commuters are sensitive to changes in the speed of the respective modes of transportation. The mode chosen depends to a large extent on the ratio of door-to-door travel times by car and transit. Freer flowing traffic in the road network will induce a higher proportion of commuters to travel by car. Conversely, faster public transport will reduce the proportion of car commuters, but the effects of such improvements will be offset if road capacity is simultaneously increased. In addition to the relative speeds of car and transit, the parking conditions at the workplace are of great importance to the choice of transport mode.     

From Boom to Bust? An Assessment of the Impact of Sustainable Development Policies on Housing in the Republic of Ireland

In many countries, moves towards sustainable development have been driven by a range of international agreements and by EU directives. This paper assesses the impact of international policy in this area on Irish housing policy and practice. To a large extent, Irish housing development has consisted of suburban sprawl on greenfield sites, low-density housing and one-off housing in rural areas. There is strong dependence on the car and very limited public transport. These unsustainable housing trends was exacerbated in recent years when the demand for housing increased significantly. The main response to this demand has been a substantial rise in the construction of housing. The paper examines the conceptualization and operationalization of sustainable housing in Irish policy and reveals that international developments have had some impact on policy but a very limited effect in practice.     

Moving up the waste hierarchy: Car boot sales,reuse exchange and the challenges of consumer culture to waste prevention

Moving up the waste hierarchy is a key priority for UK waste policy. Waste prevention requires policy interventions to promote reuse. The term ‘reuse exchange’ has been adopted by UK policy makers to describe a variety of second-hand trading outlets including car boot sales, charity shops and online exchange sites. As waste policy is based on tonnage diverted from disposal (or landfill), policy interventions to promote reuse exchange will be based on the weight of goods estimated to be flowing through these sites. This paper uses a combination of field survey data and scale-up estimation to quantify and characterise the weight of goods exchanged at car boot sales in England in 2012. This is estimated at 50–60 000 tonnes per annum. The paper emphasises that movement up the waste hierarchy brings waste policy into closer contact with household consumption practices. It draws on qualitative research to show that, for participants, car boot sales are not associated with waste prevention. Instead, car boot sales rely on stocks of surplus household goods and exemplify the culture of thrift, which enables more, not less, consumption. The paper shows the collision between the social values that inform thrift and the environmental values that underpin reuse; and it argues that the policy goal of enhanced recovery for reuse might best be achieved by working with consumer culture. Two ways of achieving this are suggested: interventions that make it easier for consumers to do the right thing, through promoting opportunities for the circulation of stocks of surplus goods, for example, through increasing the frequency of car boot sales; and interventions which recognise that car boot sales also generate waste, which could be recovered for reuse.     

Development pattern and enhancing system of automotive components remanufacturing industry in China

Along with the increasing number of automotive output and End-of-Life vehicles (ELVs) in China, resources shortage and environmental pollution are aggravating, so the tremendous need to reuse automotive components gives birth to the industry. The Chinese government becomes to realize that it is necessary to build a conservation-oriented and environment-friendly harmonious society. As the ultimate form of recycling, remanufacturing will be an effective method to promote the development of Chinese circular economy. The automotive remanufacturing industry in China is just at the preliminary stage, this paper presents some problems before remanufacturing, during remanufacturing and after remanufacturing, and then it points out several barriers, such as restrictive policies and regulations, consumer acceptance, scarcity of technologies, etc. Like many other developed countries, Chinese remanufacturing industry will also experience the primary stage, growth stage and developed stage. while the emphasis of resources input will not be the same. By analyzing the resources input characteristics at different development stages, three development patterns, such as the Government Incenting Pattern, Technology Driving Pattern and Market Leading Pattern, are put forward. At present, the cooperation of the government, industry, universities and research institutes, etc, will jointly construct the enhancing system of automotive components remanufacturing industry in China. Finally, it concludes with a summary and some suggestions in the field.     

ALTERNATIVE MODELS FOR ESTIMATING THE TIME SERIES COMPONENTS OF WATER CONSUMPTION DATA1

ABSTRACT: Understanding the behavior of different time-series components of water consumption data is essential for a more effective analysis of economic incentive effects of alternative policy measures and also closer integration of water supply and demand management. Additive and multiplicative models are used to analyze the trend (T), cyclical (C), seasonal (S) and irregular (I) components. The stepwise regression method was applied to 187 data points (January 1960 to July 1975), each representing average daily water consumption within the service area of the Honolulu Board of Water Supply. Although statistically similar results (R² 0.95 and 0.96 and respective corresponding F-ratios 277 and 307) might suggest little difference in model performances, closer analysis of the results point to important multiplicative effects which should be taken into account in both short-run and long-run analyses.

Vehicular air pollution and asthma: implications for education for health and environmental sustainability

Studies show a direct relationship between occurrence of asthma and increases of particulate matter in the air. Private transportation is found to be a significant contributor to this problem. The objective of this article is to explore this link between air pollution, asthma and vehicular dependency in order to provide recommendations for health and transport policy. This article focuses on the survey of literature on the relationship between vehicular air pollution and asthma; combining it with the literature on vehicular dependency or ‘car culture’ in the global context and in The Netherlands. This article exposes the imbalance of power between patient groups and polluting industries, and the government failure to protect the weaker party can be explained by corporate pressures. It will be argued that since air pollution is tied to the corporate support for the car industry and vested interests in promoting a ‘car culture’, strategic policy that claims to be concerned with public health should explicitly link the present pattern of mobility to public health. This article concludes with a recommendation for raising environmental health awareness by explicitly linking vehicular dependency to respiratory health through a combination of holistic and citizenship education.     

The mining industry in the European Union: Analysis of inter-industry linkages using input–output analysis

Input–output modelling is a useful tool in policy analysis and economic planning. This methodology is used to detect the inter-industry linkages known as forward and backward linkages. Examination of these measures provides one mechanism for identifying “key” or “leading” sectors. The main objective of this paper is to measure the linkages of the mining and quarrying industry in the European Union (EU) and to determine if any of the industry subsectors can be considered key sectors. The paper shows that three subsectors can be considered key sectors: the mining of coal and lignite and extraction of peat in Germany; mining of metal ores in Sweden; and other mining and quarrying in Austria, Denmark and Spain. These sectors are more stimulated by overall industry growth than other sectors and have greater impacts in terms of investment expenditures on the national economy than other sectors. The values of the forward and backward linkages show that the mining and quarrying is an industry that would be stimulated by an increase in a regional economy's production more than other sectors, while an increase in the mining and quarrying industry's output would not stimulate this regional economy more than an increase in other sectors.
