Nanotechnology has recently been identified with principles of sustainability and with a ‘green’ agenda generally . Some maintain that this green dream of nanotechnology is a rather ephemeral societal phenomenon that owes its existence to the campaign ploys of politics and business. This paper argues that deeper lying societal and cognitive structures are at work here that complement or even substantiate in some sense the seemingly manipulative saying of a greening of nanotechnologies. Taking seriously the concept of ‘green nano’, this (...) paper examines the common ground between sustainability discourse and the discourse of nanotechnology. Green nanotechnology is understood as a boundary concept in which disparate discourses and concepts join together. The primary concern of the paper is to show that nanodiscourse and ecodiscourse share visions of control and of excess. Both ecotechnology and nanotechnology accept and incorporate arguments about limited growth, and each develops strategies of control—be it through a new-found precision in the control of material flows or through greater efficiency in product design.

Green design tools are emerging as a new response to the dilemmas that architects and designers face in preventing the toxic impacts of building construction. Environmental health advocates, scientists, and consulting firms are stepping in to provide designers with new tools—including science-based assessment methods, standards, databases, and software—intended to help structure and inform decision-making in sustainable design. We argue that green design tools play an important but largely uninvestigated role in giving designers new forms of influence while mediating how designers’ (...) values are translated into actual design choices. Tool makers embed their own values and politics into the construction of the tools, which function as “black boxes”—their internal operations are understood as less important than their outputs for informing sustainable design. Using the green building movement as a case study, we consider three tools for selecting environmentally benign materials: the GreenScreen for Safer Chemicals, Pharos, and the Health Product Declaration. Examining controversies about the scientific validity of green design tools, we suggest that they are rooted in value conflicts and tensions in the politics of chemical knowledge. Transparent engagement with values and politics among tool developers and users could strengthen the legitimacy and credibility of green design tools. (shrink)

The environmental and social costs of consumer societies have increasingly been recognized. Achieving sustainable household consumption requires an understanding of the underlying roots of current consumption levels. Using the case study of menstrual care practices, different theoretical frameworks—or narratives—for understanding household consumption are evaluated. The author argues that theories of consumption that focus on individual choice based on assessments of convenience or cleanliness, or only on cultural imperatives need to be expanded to take account of the wider political–economic context. Using (...) commoditization theory helps explain not only why mass-produced, disposable menstrual products are dominant in free market societies but also why certain theories of consumption are more prevalent.

Computer models are frequently used tools in hydrological research. Many decisions related to the model set-up and configuration have to be made before a model can be run, influencing the model results. This study is an empirical investigation of the motivations for certain modeling decisions. Fourteen modelers from three different institutes were interviewed about their modeling decisions. In total, 83 different motivations were identified. Most motivations were related to the team of the modeler and the modelers themselves, “Experience from colleagues” (...) was the most frequently mentioned motivation. Both institutionalization and internalization were observed: a modeler can introduce a concept that subsequently becomes the teams' standard, or a modeler can internalize the default team approach. These processes depend on the experience of the modeler. For model selection, two types of motivations were identified: experience (from colleagues or the modelers themselves), and model vision (the model has assets that align with the modeling vision). Model studies are mainly driven by context, such as time constraints, colleagues, and facilities at the institute, rather than epistemic (such as aligning with the modeling vision). The role of local context in the construction of and the value assigned to models shows that models are social constructs, making model results time, and place dependent. To account for this context in the estimation of the robustness of model results, we need a diversity of opinions, perspectives, and approaches. This requires transparent modeling procedures and an explicit modeling vision for each model study. (shrink)

Infrastructure management has traditionally been based on a logic of predict and provide in which rising demand was met with an increase in infrastructure capacity. However, recent changes in political, economic, and environmental priorities mean that projects such as new roads, which simply expand supply, have become more controversial, and that reducing demand is now a key challenge. This article is about the different ways in which infrastructure managers have tried to achieve reductions in demand, as well as the range (...) of plans that blend various proportions of technological and institutional innovation. For the sociology of science, the controversies over these urban environment plans are interesting not just because they are scientific controversies but because they are controversies over the relationships between science, expertise, technology, and society. As a result, the authors argue that sociologists of science have a contribution to make as experts in their own right. This article argues that the sociology of scientific knowledge needs to move beyond symmetry and neutrality and outlines some of the ways in which SSK can make a difference by repositioning itself at the center of contemporary policy debates.

A synthesis of neo-Schumpeterian evolutionary, sociological, and historical coevolution ary models could be used for constructive technology assessment, aimed at the active management of the process of technological change. This article proposes a synthetic quasi-evolutionary model, in which variation and selection are neither independent nor coincidental processes. Variation and selection are linked by actors, resulting in the actor role labeled technological nexus. On the basis of the quasi-evolutionary approach, three constructive technology assessment strategies are proposed: stimulating alternative variations, changing the (...) selection environment, and creating or utilizing technological nexus. The usefulness of these concepts is demonstrated for the case of clean technolo gies. Ultimately, a conscious application of these strategies could result in a new actor role for government as a creative social regulator of technological change. (shrink)

This article expands upon the notion of ideology as a material phenomenon, usually in the form of institutionalized, taken-for-granted practices. It draws on Herbert Marcuse and related thinkers to conceptualize technological solutions to environmental problems as materialized ideological responses to social-ecological contradictions, which, by concealing these contradictions, reproduce existing social conditions. This article outlines a method of technology assessment as ideology critique that draws attention to: (1) the social determinants of the given technology; (2) whether the technology conceals or masks (...) social-ecological contradictions; (3) whether the technology reproduces existing social conditions; and (4) whether the technology may be used for more rational or emancipatory ends in different social conditions. The examples of solar geoengineering and agricultural biotechnology are examined and it is found that, in each case, these technological solutions conceal social-ecological contradictions and support the current economic system and those benefiting from it, while precluding other alternatives.
