The sound of risk and the art of change. Towards a deeper understanding of nuclear risk perception

The dissertation is an approach to cover different views on risks and specifically on nuclear risk perception. The dissertation aims to contribute theoretical foundations as well as empirical evidence on the questions of how to perceive and to govern global risks, such as nuclear technology. Technological risks, we face today, can be seen as products of the era of modernity. We created them, seeing them as chance and controllable. Major nuclear accidents repeatedly provide evidence that the assumption of controllability is too strong. A paradigm shift is needed in scientific reasoning. In the beginning of this work an approach is developed to define risks as a semi-normative concept of individual judgement as well as objective foundation. The dissertation emphasizes that individual’s risk perception can in its extremes be solely based on feelings, on the one hand, or on pure objective information, on the other. This can create tension in societies if expert’s risk evaluation does not match individualistic judgements of risks. As a result, social protests on local level happen, broader civil society movements are formed or new political parties, such as the Green party in Germany are established. On the individual level, empirical studies indicate that risk perception is clustered within societies. Women, for example, systematically evaluate the use of nuclear energy as more dangerous as man. To provide empirical evidence, this work contains three empirical chapter using data from the International Social Survey Programme (ISSP). All three chapters are interested in the question of how dangerous individuals perceive nuclear energy. Furthermore all studies are linked to the Fukushima Daiichi nuclear power plant accident in March 2011. The first study examines individual nuclear risk perception in the U.S., Great Britain, France, Germany, and Japan, before the accident. The second study uses data of country samples that contain observations before and after the accident to show how the event has an immediate effect on risk perception in societies. A third chapter using observations after the accident compares nuclear risk perception with individual’s environmental concern. The studies show how social factors, such as gender, education, social status or values shape our concerns and our view of nuclear risk. It becomes also clear that a major nuclear accident is affecting more risk averse groups, such as educated men, stronger than already concerned people creating higher levels of risk perception. A main driver of risk perception is a loss of trust in governments and its controlling agencies. The questions that remain are the question of how to govern risks and how to avoid creating risks that are perceived as very dangerous for future generations. Unanswered remains in this dissertation the question of how to design institutions that are able to pass on the knowledge of risks, such as nuclear technology, from one generation to its next generation. In order to avoid the creation of too dangerous risks for future generations, this work is advocating an adaptive and integrative risk-management model opposed to a command-and-control management model to control for social ignorance and to avoid an accumulation of risks. Nuclear technology is an example of how new risks have created new dilemma and questions we face in societies and across countries as well as across generations. Nuclear technology forces humanity also to overcome common levels of ignorance and not knowing, for example by using a different language and worldview, incorporating more information into risk assessments. It also forces all actors to create institutions and citizen’s trust into its institutions that are able create control mechanisms to avoid the harm to human beings or a catastrophe, by a series of nuclear accidents or a nuclear war. The sound of risk is teaching us how we need to change. Change is an art

Two decades of measuring environmental attitudes: A comparative analysis of 33 countries

This paper analyzes the development of environmental concern by using the three waves of the environmental modules of the International Social Survey Programme. First, we discuss the measurement of environmental concern and construct a ranking of countries according to the new 2010 results. Second, we analyze the determinants of environmental concern by employing multilevel models that take individual as well as context effects into account. Third, we explore the longitudinal aspect of the data at the macro level in order to uncover the causal relation between countries’ wealth and environmental concern. The results show that environmental concern is closely correlated with the wealth of the nations. However, environmental concern decreased in almost all nations slightly during the last two decades. The decline was lower in countries with improving economic conditions suggesting that economic growth helps to maintain higher levels of environmental concern

Two Decades of Measuring Environmental Attitudes: An Analysis of the ISSP Environmental Modules 1993, 2000, and 2010

This paper analyzes the development of environmental concern by using the three waves of the environmental modules of the International Social Survey Programme (ISSP). First, we discuss the measurement of environmental concern and construct a ranking of countries according to the new 2010 ISSP results. Second, we analyze the determinants of environmental concern by employing multilevel models that take individual as well as context effects into account. Third, we explore the impact of attitudes on environmental behavior and support of environmental policies. The results show that environmental concern is closely correlated with the wealth of nations. However, environmental concern decreased in OECD as well as non-OECD nations slightly during the last two decades. The decline was lower in countries with improving economic conditions suggesting that economic growth helps to maintain higher levels of environmental concern. Furthermore, attitudes have a stronger impact on support of environmental policies as compared to everyday environmental behavior

Social Reactions to the Climate Debate in Germany and Switzerland

Abstract In this contribution we take a look at the development of environmental concern and mobility behavior of the population in Germany and Switzerland. The proportion of survey participants who express concern about the state of the natural environment is high in both countries. However, this proportion did not increase during the last two decades despite the ongoing public debate about environmental issues. At the same time the demand for private transportation did increase in Germany by almost 20% (in Switzerland by 2.5%). However, fuel consumption per capita decreased in Germany by 6.5% and in Switzerland by 2.2%. Our time series analyses of these trends suggest that this reduction is due to the price increase of gasoline which was substantial in both countries and not due to any change in attitudes. We argue that further price increases are appropriate means to reduce fuel consumption. However, our analyses also show that the price elasticity for fuel is low.</jats:p
