We have witnessed a large increase in the number of publications on sustainability challenges over the past decade. One important characteristic of the research is with the wide variety of actors that can make use of the results. Sustainability knowledge is often not only relevant for those in academia or policy-making circles, but it can also be useful for decision-makers in a diversity of societal facets and sectors. It is therefore essential that the sustainability research community have access to a diversity of knowledge dissemination outlets, including those that extend beyond the traditional, and often inaccessible, academic publishing realms. One positive development over the past decade in sustainability research reaching broader audiences has been the proliferation of open access publication outlets. The alternative has provided greater access to scientific articles to almost anyone with an Internet connection. But, is this medium of knowledge dissemination sufficient? Are there additional channels that sustainability researchers can use to broadcast knowledge to even broader user groups?
在过去十年中,我们看到关于可持续性挑战的出版物数量大幅增加。这项研究的一个重要特点是,可以利用研究结果的行动者种类繁多。可持续性知识往往不仅与学术界或决策圈有关,而且对各种社会方面和部门的决策者也很有用。因此,至关重要的是,可持续性研究界有机会获得各种各样的知识传播渠道,包括那些超出传统的、往往无法进入的学术出版领域的渠道。在过去十年中,可持续性研究的一个积极发展是开放获取出版物渠道的激增。另一种选择为几乎任何有互联网连接的人提供了更大的获取科学文章的途径。但是,这种知识传播的媒介就足够了吗?可持续性研究人员是否可以利用其他渠道向更广泛的用户群体传播知识?

Carbon Intensities of Economies from the Perspective of Learning Curves 学习曲线视角下的经济体碳强度
IF 1.9 Q2 Social Sciences Pub Date : 2013-01-01 DOI: 10.12924/CIS2013.01020094

While some countries have achieved considerable development, many others still lack accessto the goods and services considered standard in the modern society. As CO2 emissions and development are often correlated, this paper employs the theoretical background of the Environmental Kuznets Curve (EKC) and the learning curves toolkit to analyze how carbon intensities have changed as countries move towards higher development (and cumulative wealth) levels. The EKC concept is then tested with the methodology of learning curves for the period between 1971 and 2010, so as to capture a dynamic picture of emissions trends and development. Results of both analyses reveal that empirical data fails to provide direct evidence of an EKC for emissions and development. The data does show, however, an interesting pattern in the dispersion of emissions levels for countries within the same HDI categories. While data does not show that countries grow more polluting during intermediary development stages, it does provide evidence that countries become more heterogeneous in their emission intensities as they develop, later re-converging to lower emission intensities at higher HDI levels. Learning rates also indicate heterogeneity among developing countries and relative convergence among developed countries. Given the heterogeneity of development paths among countries, the experiences of those which are managing to develop at low carbon intensities can prove valuable examples for ongoing efforts in climate change mitigation, especially in the developing world.
虽然一些国家已经取得了相当大的发展,但许多其他国家仍然无法获得被认为是现代社会标准的商品和服务。由于二氧化碳排放和发展往往是相关的,本文采用环境库兹涅茨曲线(EKC)的理论背景和学习曲线工具包来分析碳强度是如何随着国家走向更高的发展(和累积财富)水平而变化的。然后用1971年至2010年期间的学习曲线方法对EKC概念进行测试,以便捕捉排放趋势和发展的动态画面。两种分析的结果都表明,经验数据未能提供排放和发展的EKC的直接证据。然而,数据确实显示了在同一人类发展指数类别的国家中排放水平分散的有趣模式。虽然数据没有显示各国在中间发展阶段的污染程度增加,但它确实提供了证据表明,随着发展,各国的排放强度变得更加异质性,后来在较高的人类发展指数水平上重新趋同于较低的排放强度。学习率也表明发展中国家之间的差异和发达国家之间的相对趋同。考虑到各国发展道路的异质性,设法以低碳强度发展的国家的经验可以证明是当前减缓气候变化努力的宝贵范例,特别是在发展中世界。
