The new WIOD database allows for improved empirical analysis on a wide range of important environmental research questions.In this paper we demonstrate the scientific power of the WIOD database and analyze very urgent policy questions on the impacts of international trade and structural change on the environment.We apply recent econometric approaches to show the impact of international trade on the environment via its different channels as for instance to increase welfare and potentially affect environmental regulation as well as countries’sector.This approach has become known as the econometric structural decomposition method.In addition to these guidelines by the literature,an econometric panel data approach is offered to shed some light on the impact of structural change and international trade on environmental pressure,where we especially address and solve several endogeneity issues that add further complexity to the analysis.  相似文献

ABSTRACT

The media play a vital role in framing the narrative on climate change, however little work exists to assess the extent to which local media outlets increase public engagement on climate change through interaction and engagement with local academics. As temperatures rise and concerns mount that we have passed the tipping point, local media play a potentially critical role in communicating how climate change exacerbates their impact. Based on a review of extant literature on this topic, and a small pilot email survey, this article argues that scientists could be more active in increasing local salience of climate change by building trusted relationships with local media. Coverage of science in the media could benefit from closer engagement with local scientists as environmental stories often get more coverage in local media (compared to national media) which constitute an important source of knowledge on climate change. This would enable constructive discussions between local media and scientists, better translation of science to publics, increased awareness and interest of science production locally, and ultimately creating a trusted intermediary in the science-public interface.  相似文献

Carbon capture and storage (CCS) has received abundant federal support in the USA as an energy technology to mitigate climate change, yet its position within the energy system remains uncertain. Because media play a significant role in shaping public conversations about science and technology, we analyzed media portrayal of CCS in newspapers from four strategically selected states. We grounded the analysis in Luhmann's theory of social functions, operationalized through the socio-political evaluation of energy deployment (SPEED) framework. Coverage emphasized economic, political/legal, and technical functions and focused on benefits, rather than risks of adoption. Although news coverage connected CCS with climate change, the connection was constrained by political/legal functions. Media responses to this constraint indicate how communication across multiple social functions may influence deployment of energy technologies.  相似文献

There is strong evidence that a meat and dairy-based diet is a very important contributor to climate change. However, the correlation between the production and consumption of livestock and anthropogenic climate change has received minimal media coverage. The literature for English-speaking countries shows a sort of media blind spot for meat in that the news media barely address, or do not address, the responsibility of individuals' dietary choices with regard to this issue. In this paper, we provide data for press coverage in Southern Europe from a sample of the top 10 Spanish and Italian newspapers for a seven-year period (2006–2013). Data from our samples correlate with findings from previous studies. However, our comparative study suggests that there are also meaningful differences between both countries studied while their alleged Mediterranean dietary background makes no difference in terms of ethical or dietary sensitivity.  相似文献

Climate change is a phenomenon with global causes but local effects, and thus global climate change decision-making moments provide ideal opportunities to examine how local and global discourses work together—or do not—through global journalism. This case study investigates the globally focused vs. culturally bound frames used in television news coverage, in Canada and the USA, of the 2009 United Nations Climate Change Conference in Copenhagen. Initial quantitative findings that Canadian media used many more culturally bound sources than did American media contradict the past findings and suggest Canadian media engaged less in producing global journalism than did American media. A follow-up qualitative analysis not only found more global framing in the American stories, but also concluded that global sources did not necessarily create global journalism; instead, a global orientation is required.  相似文献

Climate change is an urgent problem with implications registered not only globally, but also on national and local scales. It is a particularly challenging case of environmental communication because its main cause, greenhouse gas emissions, is invisible. The predominant approach of making climate change visible is the use of iconic, often affective, imagery. Literature on the iconography of climate change shows that global iconic motifs, such as polar bears, have contributed to a public perception of the problem as spatially and temporally remote. This paper proposes an alternative approach to global climate change icons by focusing on recognizable representations of local impacts within an interactive game environment. This approach was implemented and tested in a research project based on the municipality of Delta, British Columbia. A major outcome of the research is Future Delta, an interactive educational game featuring 3D visualizations and simulation tools for climate change adaptation and mitigation future scenarios. The empirical evaluation is based on quantitative pre/post-game play questionnaires with 18 students and 10 qualitative expert interviews. The findings support the assumption that interactive 3D imagery is effective in communicating climate change. The quantitative post-questionnaires particularly highlight a shift in support of more local responsibility.  相似文献
