Policy evaluation of vehicle exhaust standards in Japan from 1995 to 2005 based on two human health risk indices for air pollution and global warming

Measures for vehicle exhaust emissions aimed at reducing either air pollution or global warming could have counterproductive effects on one another. Increasing diesel passenger vehicles, which generally have lower CO₂ emissions than gasoline counterparts, leads to increasing particulate matter (PM) emissions, while gasoline has lower PM emissions than diesel. It is said that stringent limits on PM emission factors discourages improved CO₂ emission factors. Without including both effects in a risk evaluation, one cannot evaluate whether the total risk is reduced or not. Hence, we evaluated representative exhaust emission measures based on risk evaluation for both air pollution and global warming. Considering consumer choice between diesel and gasoline passenger vehicles and emissions standards adopted in Japan from 1995 to 2005, we built five cases for vehicle policy evaluation. For each case, we estimated disability-adjusted life years (DALY) as an index of human health risk caused by lung cancer linked to inhalation exposure of elemental carbon in PM as well as due to global warming linked to CO₂. The results of our risk evaluation reveal that the case adopting the 2005 new long-term Japanese emission standard reduces the human health risk caused by lung cancer due to air pollution by 0.6 × 10³ DALY, but would increase the risk due to global warming by 31.9 × 10³ DALY compared with the case of adopting EURO 4, for the same conditions of passenger vehicle choice from 1995. These results suggest that the characteristics of Japanese emissions standards are mainly designed to reduce air pollution.     

Drinking water risk assessment in practice: the case of Swedish drinking water producers at risk from floods

To achieve a safe and reliable drinking water supply, water producers need to manage a large range of risks regarding both water quality and quantity. A risk management approach where risks are systematically identified and handled in a preventive manner is promoted by the World Health Organization and supported by researchers and drinking water experts worldwide. Risk assessment is an important part of such a management approach, and a variety of tools for risk assessment are described in the literature. There is, however, little knowledge of how drinking water risk assessment is performed in practice, including which tools that are actually used. This study investigates the use of risk assessment tools, and the approach to risk management, on a local level in the Swedish water sector. It is based on interviews with key persons from a targeted selection of water producers. We find that the application of tools as well as the approach to risk assessment and management differs considerably between the water producers. The tools most frequently used are mainly the ones promoted or required by Swedish national organizations. Although many of the water producers have done some kind of risk assessment, most have not implemented a risk management approach. Furthermore, their knowledge of the concepts of risk and risk management is often limited. The largest challenge identified is to prioritize risk assessment, so that it is actually performed and then used as a basis for managing risk in a systematic way.     

An improvement selection methodology for key performance indicators

Key performance indicators (KPIs) are critical measures for determining the health of a manufacturing plant in relationship to the plant’s goals. In today’s competitive environment, manufacturers cannot be careless about their business; in fact, they must ensure that their KPIs are effective and use them to make improvements when necessary. This paper describes a method for suggesting improvements to a manufacturer’s KPIs, based on the results achieved from a workshop to score the KPI on a number of predefined criteria. The approach uses a prospect theory approach to weight the scoring. Different problem formulations were derived that allow for both recommendations for improvements and the recommendations for disinvestments to over-performing KPIs. The authors applied the developed approach to two workshop outputs, each from independent manufacturers, and the results highlighted the significant difference between the two manufacturers in terms of improvement priorities and KPI assessment. The optimal improvement suggestions were compared to those found through a fast heuristic. It was determined that given the underlying assumptions of the approach that the heuristic solutions were just as adequate as the optimal ones.     

Heat wave vulnerability and exposure mapping for Osaka City,Japan

Heat waves and heat-related stresses are increasing environmental concerns in urban areas. The impact of heat waves is dependent on the intensity and duration of each event and on underlying environmental and socio-demographic factors which influence population vulnerability. In order to develop effective adaptation strategies, it is important to develop a method to clearly identify the most vulnerable areas based on these factors. The purpose of this study is to develop and map a heat wave vulnerability index combined with heat exposure analysis to identify areas where interventions can be targeted. The vulnerability index was derived from a principle component analysis of eight key variables that influence heat wave vulnerability. Eight proxy measures of vulnerability were obtained from 2010 census and land-use data for the 1904 census districts of Osaka City. Three principle components explained >77 % of the variance (age, employment and education; social isolation; density and lack of green space). The components were combined and weighted to produce a vulnerability score for each census district. The vulnerability scores ranged from 0 to 106, were categorised into eight vulnerability levels and were overlaid with fine-scale air temperature observations. The resulting output identified the distribution of population vulnerability and exposure. This assessment of vulnerability, combining exposure and sensitivity components, can provide precedent for efficient, targeted action to be taken to reduce the impact of heat waves at present and under climate change.     

Clarifying relationships between participatory approaches,issues, processes,and results,through crosscutting case analysis in Japan’s environmental,energy, and food policy areas

Participatory public engagement approaches such as Consensus Conferences, Deliberative Polling^®, and Planning Cells have been used to try and resolve environmental disputes in Japan; however, the strengths and weaknesses of these approaches have not been analyzed adequately or comprehensively. This paper evaluates practical applications of each of the above participatory approaches and conducts a crosscutting analysis of these applications to evaluate how effectively each approach provides scientific information to participants and to consider how the quality of deliberations that occur during these processes affect their outputs. Based on existing classification of participatory processes, and methodology for public involvement in US environmental decision-making, this study compares and contrasts the processes and outcomes of 25 participatory planning case studies in Japan. After compiling a case inventory of participatory approaches, the features of one approach are documented using qualitative analysis, and the aspects of four other approaches are confirmed using crosscutting analysis. In so doing, the likely strengths and weaknesses of each approach are suggested as follows. When discussions require an understanding of scientific knowledge, the Consensus Conference tends to be more suitable than the DP approach. If the consensus of participants is expected, the Consensus Conference is also thought to be suitable. But through a DP process or Simplified Planning Cells approach, we can know the quantitative portion of each opinion through results of ballots. In sum, new participatory approach that incorporates strengths of the Consensus Conference and the Simplified Planning Cells into Local Environmental Planning is needed. Thus, the quality of consensus building could be improved.     

Food: From Commodity to Commons

Our food and farming system is not socially, economically or ecologically sustainable. Many of the ills are a result of market competition driving specialization and linear production models, externalizing costs for environmental, social and cultural degradation. Some propose that market mechanisms should be used to correct this; improved consumer choice, internalization of costs and compensation to farmers for public goods. What we eat is determined by the path taken by our ancestors, by commercialization and fierce competition, fossil fuels and demographic development. Based on those, governments and the food industry are the choice architects who determine what we eat; consumer choice plays a marginal role. Using market mechanisms to internalize cost and compensate farmers for public goods has been proposed for decades but little progress has been made. There are also many practical, ethical and theoretical objections to such a system. The market is not a good master for a sustainable food system. Instead we need to find new ways of managing the food system based on food as a right and farming as a management system of the planet Earth. The solutions should be based on relocalization of food production and de-commodification of food and our symbionts, the plants and animals we eat.     

The Normative Limits of Consumer Citizenship

In political philosophy, citizenship is a key concept. Citizenship is tied to rights and duties, as well as to concepts of social justice. Recently, the debate on citizenship has developed a new direction in focusing on qualified notions of citizenship. In this contribution, I shall defend three claims. Firstly, consumer citizenship fits into the discussion of qualified notions of citizenship. Secondly, the debate on qualified notions of citizenship cannot be detached from the normative claims in the philosophy of citizenship more generally. In particular, duties and rights receive a distinct shape when debated in terms of “consumer citizenship”. Thirdly, I shall argue that further normative limits can be established by discussing qualified notions of citizenship as items of a list that need to cohere in normative terms. I shall pay particular attention to environmental citizenship.     

Consuming for the Sake of Others: Whose Interests Count on a Market for Animal-Friendly Products?

Many Europeans are concerned about the living conditions of farm animals because they view animals as beings that possess interests of their own. Against this background the introduction of an animal welfare label is being intensively discussed in Europe. In choosing a market-based instrument to take these concerns into account, normative judgments are made about the formation of preferences, the value system that is implicitly assumed, and the distribution of property rights. From the perspective of classical institutional economics it can be shown that the introduction of a label as an institutional change does not redefine institutions in a way that allows them to consider the interests of animals for their own sake. Rather, the label only redefines the property rights that humans have over animals. The market segregation into privileged and normal animals conflicts with the idea of equality between sentient animals. Within the group of humans only the interests of those who act on markets count. The commodification of their moral concerns assumes that people always decide based on their own interests, which can be traded off. The lexicographical ordering of preferences, which occurs when humans view animals as entities with rights, is not compatible with the normative assumptions of markets. Furthermore, interpreting animal suffering as market failure that can be corrected by labeling impedes a reasoned dialog within the society about the values and beliefs that serve as a basis for preference formation. Thus, an animal welfare label cannot replace a fundamental societal debate about legal standards on animal well-being.     

Determinants of Individual Attitudes Toward Animal Welfare-Friendly Food Products

Animal welfare involves societal and human values, ethical concerns and moral considerations since it incorporates the belief of what is right or what is wrong in animal treatment and care. This paper aims to ascertain whether the different dimensions of individual attitudes toward animal welfare in food choices may be characterized by general human values, as identified by Schwartz. For this purpose, an EU-wide survey was carried out, covering almost 2500 nationally representative individuals from five European countries. Compared with the previous literature this study shows a twofold novelty: (1) it develops a general framework to link individual enduring beliefs and attitudes toward animal welfare attributes in food choices; (2) the framework is analyzed within a broad-based cross-country study. Our empirical results prove that human values related to self-transcendence are strongly associated to overall animal welfare attitudes and especially to those explicitly related to food choices, while values related to the spheres of self-enhancement and conservatism are significantly associated to less sensitive attitudes to animal welfare. Moreover, our results appear to indicate that a determinant of animal welfarism in food choices is potentially associated to individual concerns regarding food safety issues.     

Think Global,Buy National: CSR,Cooperatives and Consumer Concerns in the Norwegian Food Value Chain

In a world where issues of food safety and food security are increasingly important, the social responsibility of central actors in the food chain—producers and the main grocery chains—becomes more pressing. As a response, these actors move from implicitly assuming social responsibilities implied in laws, regulations and ethical customs, towards explicitly expressing social responsibilities. In this paper, we discuss the ethical values relevant for the social responsibility of central food producers and retailers in Norway, one of the most subsidized and protected areas of food production in the world. How do the actors perceive and express their social responsibility, and—given their position in the local, national and global market—how should they handle these responsibilities? We analyze Tine and Nortura, two producers owned by farmer cooperatives with market regulator function, as well as Coop—a dominant grocery chain in Norway, with basis in the same public ownership model as the farmer-owned cooperative producers. While the complex roles of these key actors in the Norwegian food market have been criticized from several angles, we argue that these multifaceted roles put them in a good position to promote informed consumer choices in a globalized market.
