The UK packaging regulations and performance measures in environmental management systemsCollins-Webb, Gail Julie January 2001 (has links)
The measurement of industries' environmental performance is evolving as society strives towards the ideal of sustainability. Environmental performance indicators within different industries are being developed in order that industry can measure and evaluate performance and report on their level of environmental protection to different stakeholders. Although there are many studies of environmental performance measures, they have tended to focus on those that apply to manufacturing or 'dirtier' industries. This is mainly because environmental legislation, a major driver of environmental programmes in companies, has targeted these industries. Recent legislation on packaging has focused, for the first time, on environmental impacts that are pertinent to all industry sectors alike. This has given rise to an industry-wide set of environmental performance measures for packaging and packaging waste. This 'producer responsibility' legislation has marked the turning point as more legislation is formulated at the European and national level to holistically tackle the environmental impacts of product life-cycles. Current research has concentrated on the development of performance measures for a service-orientated business that is subject to legislation concerning packaging waste, using ICL (International Computers Limited) plc. as a case study example. Particular attention has been given, in this research, to the identification of EPIs and their integration into an ISO 14Q01 certifiable environmental management system for the purposes of demonstrating continuous improvement. A risk assessment methodology is applied to demonstrate the effects of business constraints in the decision-making process regarding environmental programmes. The impacts of the UK Producer Responsibility Obligations (Packaging Waste) Regulations 1997 on the organisation and the necessary steps that the-company has had to take in order to comply with the legislation have been examined. From this study a compliance methodology has been developed and it has been demonstrated how an organisation can achieve compliance and conserve valuable resources for improving its environmental performance. Finally, a survey has been carried out in order to assess the impacts of the UK Packaging Regulations on the environmental performance of industry. From this study a model has been developed for the application of EPIs to guide policy makers in the formulation of environmental legislation and the implications for future producer responsibility legislation.

Earthquake risk assessment and management : case study, CyprusKythreoti, Stella January 2002 (has links)
Earthquakes are amongst the worst natural disasters on Earth, resulting in an annual average of around 10,000 fatalities last century and progressively increasing in the amount of economic damage they cause, reaching US $20 billion per annum this decade. The mitigation of the unwanted consequences of earthquakes is normally achieved by Risk Management Strategies (RMS), which rely on the development of Earthquake Risk Assessment (ERA) techniques. This thesis aims to develop a framework for ERA for medium seismicity regions that incorporates the spatial aspects of the hazard and risk evaluation. The framework is used to undertake ERA for the island of Cyprus, and the information is used to propose RMS. The ERA framework relies on comprehensive data on the location, value and vulnerability of buildings and the population distribution. These data were collected from the various Cyprus Government Departments. Various hazard and attenuation models are examined, and the effect of their variability is taken into account through Monte Carlo simulations. The estimated annual risk for Cyprus is just below £ 10 million CY. This value was estimated based on the use of the re-appraised historical data for the past-century. Comparisons with other seismic hazard assessment methods, such as recurrence relationships, have revealed that, without a spatial distribution model, such approaches are unsuitable for ERA. Though the maximum intensities predicted are in line with the ones that underpin the aseismic code of Cyprus (CCEAA-CFEE, 1994), the predicted design accelerations are higher than given in the code. Hence, new seismic accelerations are proposed. Despite that, the current reduction in risk is comparable to the additional cost of aseismic design. Seismic retrofitting was also examined and it was found that as part of a general modernisation scheme seismic upgrading is cost effective. However, whatever the state of the building, it is recommended that earthquake insurance should be made mandatory. The current seismic insurance rates appear to be fair, though they seem to underestimate the risk in the areas of high seismicity. The number of likely human losses is also estimated. This study concludes that the result of ERA is heavily dependent on the models and data used, and both require constant updating for the ERA results to remain meaningful.

Holistic environmental assessment of oil and gas field developmentSalter, Edward Robert Edmund January 2000 (has links)
This study has developed a new life-of-field, goal orientated process of analysis called Holistic Environmental Assessment (HEA). HEA assesses the total environmental risk associated with a proposed oil and gas field development. It prioritises environmental risks and identifies cost effective strategies to reduce them. For the first time the process was applied to a real 'case study' field development programme to test its effectiveness. The application identified that it is a useful tool to help design eco-efficient and costeffective oil and gas field developments. Furthermore, it was discovered that much of the information required by HEA could be obtained in a quick and user-friendly format. The new assessment process was developed after a review of the interaction of the offshore oil and gas industry with the environment, and techniques employed to evaluate this interaction. The review identified that the industry interacts with the environment in a number of different ways, and that the level of interaction transgresses the boundaries of sea, air and land locally, regionally and internationally. Legislation and public concern demand no damage to the environment from offshore oil and gas field exploration and development. UK environmental legislation and people's expectations for environmental performance are in a state of change. This change, coupled with the uncertainty over how resilient the environment is to perturbation, and the increasing risk of environmental liability presents a need for operators to clearly manage environmental information and assess total environmental risk. It was discovered that Environmental Assessment, Lifecycle Analysis and Cost Benefit Analysis, when used separately, failed to assess total environmental risk, but when used in combination under the HEA process could. Many organisations, such as the British Medical Association, European Oilfield Speciality Chemicals Association, the Royal Ministry of Petroleum and Energy (Norway) and Shell Expro, now recognise that a holistic approach is essential to assess total environmental risk. The author proposes that HEA would be effective as a software tool to analyse different environmental risk mitigation systems. This would facilitate the identification of a system that steers an operator towards the triple bottom line of Sustainable Development.

Assessment of financial risk in renewable biodiesel firmsVahlström, Tobias, Cavka, Adnan January 2015 (has links)
Energy consumption in the transport sector is expected to increase substantially over the coming decades. The uncertainty in the forecasts are relatively high regarding the size of the increase but reports from the US Energy Information Administration (EIA) points to an increase of 56 percent between 2010 and 2040 (IEO2013, 2013, p. 9). World Energy Council forecasts an increase between 30 and 85 percent, depending on the impact of various factors such as market regulation, population growth, urbanization, and the availability of fossil energy (Global Transportation Scenarios 2050 (TSG 2050), 2011, p. 4-5). Some of this energy could come from advanced renewable fuels such as advanced renewable biodiesel. The commercialization of advanced renewable biofuels has however been slow even though the technology has long been considered mature for large scale production. External market factors that are frequently blamed for the lack of commercialization are lack of political support, low crude oil prices, high raw material prices, and notable profitability for producers of first generation biofuels. Previous studies further suggest that advanced biofuels are expensive to produce (Demirbas, 2010; Milbrandt et al., 2013) and that the companies operating in the industry hold high financial risks (Miller et al., 2013). This study examines the systemic financial risks as well as the estimated returns that the market places on companies active in the emerging advanced biodiesel industry. The results from the study indicate, contrary to previous studies and current external market factors that the systematic risks are not considerable higher for the advanced biodiesel industry than the market average or the established biofuel industry. This is despite the fact that oil prices have been low, raw materials prices high and that the uncertainty surrounding the political forms of support for the industry during the studied period have increased. This should have resulted in increasing rather than decreasing financial risk in relation to the previous studies of the advanced biofuel sector. Important factors that contribute to the results obtained in this study are circumstances that previous studies have completely disregarded, factors that may be beneficial for the studied companies. The studied firms are showing noteworthy profitability, access to substantial working capital, relatively low ratios between stock prices and cash flows. Furthermore, the analyzed companies have a business structure that other studies so far have completely ignored, e.g. they are structured as "biorefineries". This means the studied firms, similarly to conventional petroleum refineries, are producing and trading various products produced from the same raw material. The difference being that the analyzed firms use renewable raw materials rather than crude oil to produce the commodities. The firms thus possess an "option-based" diversification strategy which may be perceived by the market as a future real option. In contrast to focused firms these firms may simply change their business focus based on changes in prevailing external market factors or decreasing profitability in any part of the company. In accordance with the theories of the effective market hypothesis theory and random walk the market has access to all this available knowledge regarding these firms’ specific factors, pricing the risks on this knowledge these as well as prevailing external market factors. The results of the study suggest that the firm-specific factors in the studied companies may be more important than some of the considered external market factors in the pricing of financial systemic risks.

Assessing crowd safety risks : a research into the application of the risk assessment principles to improve crowd safety management and planning in major public venuesAu, Siu Yam Zachary January 2001 (has links)
This thesis considers the subject of crowd safety and investigates how the application of risk assessment can provide support for decision making in crowd safety management and planning. The focus is on major public venues and events where large crowds arc a normal part of the operation. Conventional methods of assessment tend to be ad hoc, reactive and rely on individual experiences. The risk assessment approach, which is comprehensive, systematic and pro-active, can help to overcome these shortfalls. Risk assessments have already been successfully applied in many workplaces, ranging from high hazard industrial plants to the office environment. However, this thesis argues that for it to be of benefit, the risk assessment must be appropriate to the nature of the operation and the nature and the extent of the hazards involved. The existing risk assessments are inappropriate to crowd safety in this respect and a more suitable methodology is required. In order to identify the methods and tools that could provide the potential solutions to the problems of assessing crowd and behaviour related hazards, a review of other risk assessments was conducted. It has highlighted a number of techniques and tools that could be applied to assess crowd safety risks. Based on the criteria mentioned above and the findings of this review, a prototype crowd safety risk assessment methodology was developed. A series of trials were conducted to evaluate the validity and usability of the prototype. Revisions were made accordingly to produce the final draft. Experiments and a questionnaire survey were then carried out on the final draft to test and verify the methodology. In general, they show that the methodology has led to an improvement in most aspects of crowd safety risk assessment. In the experiments that compared the methodology against methods representing the existing risk assessments and the conventional way of assessing crowd safety, subjects using the methodology tend to perform better in most areas. More hazards were identified. In the evaluation of risks, better consistency was achieved between individuals using the methodology. However, their judgements appeared to be less consistent over time. The use of a larger rating scheme with more choices available in the methodology could have an impact on consistency in risk evaluation. Another key factor could be that the subjects who took part in the experiments were all novice assessors. Possible learning effect may have occurred in between experiments, which could have resulted in a change of mind over time. If this is the case, this result could be an indication that the methodology is more sensitive to changes in risks or risk perception. It will be interesting to find out if experienced assessors can achieve better consistency. By and large, the experiments and questionnaire survey have served to verify, at least in part, the arguments that risk assessment is better than the conventional assessment method and that there are more benefits to be gained when the risk assessment is more appropriate to the nature and the extent of the crowd safety hazards that could arise in major public venues. Nevertheless, it is important to recognise that the research work presented in this thesis is merely the first step towards a crowd safety risk assessment methodology. There are outstanding issues yet to be resolved, not least the issue of the apparent lack of consistency over time in risk evaluation. This thesis has identified the research and development work that is required to resolve these issues and to further the benefits that risk assessment could bring to crowd safety.
