The politics and policy of carbon capture and storage: Framing an emergent technology

Over the past decade carbon capture and storage (CCS) has attracted increasing international attention as a climate change mitigation option and moved into the center of climate policy debates and negotiations. This special issue of Global Environmental Change brings together leading scholars to analyze the politics, policy and regulation of CCS in cross-country comparisons as well as in a global context. The aim is to contribute on two fronts: first, by applying concepts, theories and methodologies from the social and policy sciences, to elucidate how societies are engaging with CCS as a mitigation option; and secondly, to point toward a future research agenda which, while exploring basic aspects of technology development as situated in a social context, would also be aligned with the needs of the climate and environmental policy community. The contributions address at least one of three inter-related research areas; CCS and the emergence of long-term climate and energy strategies; regulation, policy instruments and public acceptance; and international politics and CCS in developing countries.

Carbon forestry in West Africa: The politics of models,measures and verification processes

In a context of neo-liberal environmental governance, imperatives for global climate change mitigation are motivating a new round of policy initiatives and projects aimed at carbon forestry: conserving and enhancing forest carbon stocks, and trading these values in emerging carbon markets. In this context modelling and measurement, always significant in framing and justifying forest policy initiatives, are of renewed importance, with a growing array of protocols focused on counting and accounting for forest carbon as a commodity. This article draws on perspectives from science and technology studies and environmental discourse analysis to explore how these modelling and measurement processes are being co-constructed with forest carbon policies and political economies, and applied in project design in local settings. Document analysis and key informant interviews are used to track and illustrate these processes in a pair of case studies of forest carbon projects in Sierra Leone and Ghana. These are chosen to highlight different project types – focused respectively on forest reserve and farm-forestry – in settings with multi-layered histories of people-forest relations, landscape change and prior project intervention. The analysis shows how longer established framings and assessments of deforestation are being re-invoked and re-worked amidst current carbon concerns. We demonstrate that measurement processes are not just technical but social and political, carrying and thus cementing particular views of landscape and social relations that in turn make likely particular kinds of intervention pathway, with fortress style conservation or plantations becoming the dominant approach. In the process, other possibilities – including alternative pathways that might treat and value carbon as part of complex, lived-in landscapes, or respond more adaptively to less equilibrial people–forest relations, are occluded.     

Mapping the ideological networks of American climate politics

How do we understand national climate change politics in the United States? Using a methodological innovation in network analysis, this paper analyzes discussions about the issue within the US Congress. Through this analysis, the ideological relationships among speakers providing Congressional testimony on the issue of climate change are mapped. For the first time, issue stances of actors are systematically aggregated in order to measure coalitions and consensus among political actors in American climate politics in a relational way. Our findings show how consensus formed around the economic implications of regulating greenhouse gases and the policy instrument that should do the regulating. The paper is separated into three sections. First, we review the ways scholars have looked at climate change policymaking in the United States, paying particular attention to those who have looked at the issue within the US Congress. Next, we present analysis of statements made during Congressional hearings on climate change over a four-year period. Our analysis demonstrates how a polarized ideological actor space in the 109^th Congress transforms into a more consensual actor landscape in the 110^th Congress, which is significantly less guided by partisan differences. This paper concludes by discussing how these findings help us understand shifting positions within American climate politics and the implications of these findings.

Environmental commitments in different types of democracies: The role of liberal,social-liberal,and deliberative politics

Since a more substantial recognition of environmental degradation in the 1960s, the scholarly community has looked at democracy with mixed feelings. Some assert that democracy is devastating for the environmental performance, some claim the opposite, while others suggest that certain democratic models are more successful than others in paving the way for sustainability. Both political theorists and empirical scholars add fuel to this debate, and neither has settled the argument yet. In this paper we make use of recently collected data from the Varieties of Democracy project on different conceptions of democracy and address both these literatures. We empirically test whether different features of democracies, i.e., liberal in its thinner understanding, social-liberal, and deliberative, are more or less beneficial for environmental commitments. We investigate which of these features make democracies more prone to produce environmental policy outputs – adopt climate laws, deliver on them, develop stringent environmental policies, and incorporate sustainability into economic policies. We find that democracies with stronger deliberative features adopt more, but not necessarily stricter or more effective, environmental policies. Instead, democracies with stronger social-liberal features adopt both stricter and more effective policies.
