Is forest carbon sequestration at the expense of bioenergy and forest products cost-efficient in EU climate policy to 2050?

Forest management affects the quantity of CO₂ emissions in the atmosphere through carbon sequestration in standing biomass, carbon storage in forest products and production of bioenergy. The main question studied in this paper is whether forest carbon sequestration is worth increasing at the expense of bioenergy and forest products to achieve the EU emissions reduction target for 2050 in a cost-efficient manner. A dynamic cost minimisation model is used to find the optimal combination of carbon abatement strategies to meet annual emissions targets between 2010 and 2050. The results indicate that forest carbon sequestration is a low-cost abatement method. With sequestration, the net present costs of meeting EU carbon targets can be reduced by 23%.     

Climate Change and Asset Prices: Are Corporate Carbon Disclosure and Performance Priced Appropriately?

This paper empirically assesses the relevance of information on corporate climate change disclosure and performance to asset prices, and discusses whether this information is priced appropriately. Findings indicate that corporate disclosures of quantitative greenhouse gas (GHG) emissions and, to a lesser extent, carbon performance are value relevant. We use hand‐collected information on quantitative GHG emissions for 433 European companies and build portfolios based on GHG disclosure and performance. We regress portfolios on a standard four factor model extended for industry effects over the years 2005 to 2009. Results show that investors achieved abnormal risk‐adjusted returns of up to 13.05% annually by exploiting inefficiently priced positive effects of (complete) GHG emissions disclosure and good corporate climate change performance in terms of GHG efficiency. Results imply that, firstly, information costs involved in carbon disclosure and management do not present a burden on corporate financial resources. Secondly, investors should not neglect carbon disclosure and performance when making investment decisions. Thirdly, during the period analysed, financial markets were inefficient in pricing publicly available information on carbon disclosure and performance. Mandatory and standardised information on carbon performance would consequently not only increase market efficiency but result in better allocation of capital within the real economy.     

Revisiting carbon disclosure and performance: Legitimacy and management views

With corporate disclosure of carbon emissions rapidly increasing, the long-standing question remains whether carbon disclosure has any influence on the improvement of carbon performance. Previous studies of environmental disclosure and performance have predominantly focused on whether disclosure is a substitute for poor performance. Little attention has been devoted to the more important question about how changes in disclosure may lead to subsequent changes in performance over time. Following the rationales taken by the legitimacy and management perspectives, we revisit the relationship between carbon disclosure and performance, with a focus on changes that disclosure may (or may not) create. Using a change analysis of Global 500 companies and their carbon emission and disclosure data released between 2008 and 2012, this study finds that the change in carbon disclosure levels is positively associated with a subsequent change in carbon performance (examined through direct and indirect carbon emission intensities). Thus, regardless of whether disclosure has been used as a legitimising tool for prior poor performance, this study confirms that carbon disclosure motivates companies and creates an ‘outside-in’ driven effect for subsequent change and improvement in carbon performance. However, the association between changes in carbon disclosure and performance is relatively weaker in high energy-intensive firms.     

Carbon Cap-and-Trade in China: A Comprehensive Framework

This article proposes a comprehensive framework to explore a possible carbon cap-and-trade scheme in China. By applying the case of China, our empirical results present the demand side and supply side of carbon-emission permits in the market and several other significant findings: (i) carbon dioxide (CO₂) marginal abatement cost varies a lot among different regions; (ii) in total, CO₂ emissions could have been reduced by 5.14 billion tons if all the provinces had achieved their anticipated environmental performance during 1997–2014; (iii) the equilibrium price of CO₂ trading is 241 RMB/ton, irrelevant to the original allocation of allowances.     

略论低碳经济的发展向度与意义

低碳经济作为一种新的经济形式,无论是理论研究还是实践探索都呼唤发展哲学的观照。低碳经济作为一种新的发展模式,具有鲜明的低代价发展向度、普世的公正发展向度及强烈的创新发展向度,这对于人类社会的持续发展和文明跃迁具有重大而深远的意义。     

Promoting Giving Campaigns in University Websites: A Cross-cultural Comparison between the United States and South Korea

ABSTRACT

This study was designed to compare the ways the websites promote giving campaigns between the United States and South Korea. Furthermore, this study explored how the campaign appeals are associated with the distinct cultural values between universities in the United States and Korea. Guided by a content analysis of 200 universities in the United States and South Korea, the findings of this study demonstrated that, compared to the Korean university websites, U.S. university websites more frequently targeted university-affiliated donors, including alumni, students, parents, and so forth, and used multimedia-based exemplars about the giving campaigns.     

马克思主义文艺思想的现实指引——六中全会决定和胡锦涛讲话理论溯源

党的十七届六中全会关于深化文化体制改革推动社会主义文化大发展大繁荣若干重大问题的决定，和胡锦涛总书记在中国文联第九次和中国作协第八次代表大会上的讲话，都从马克思主义文艺思想出发，在艺术实践规律的基础上提出并阐发了许多文艺理论的重大问题。而关于文艺家要承担历史责任、提倡文以载道、鼓励文艺原创、自觉抵制低俗之风等，都是当前深具实践意义与艺术学理意义的重大问题。如从理论与实际相结合的意义上加以深入领会，必然会有力推动社会主义文艺的大发展大繁荣的伟大战略目标的早日实现。     

中国鞋类产品出口受阻的原因及对策

长期以来,“薄利多销”的低价策略成为我国鞋类企业扩大出口创汇、走向国际市场的一大法宝,但从近期我国鞋类出口面临一系列的贸易摩擦来看,低价策略并非当今出口企业的最佳选择,若不及时调整这种策略,可能会严重制约企业的发展。本文分析了鞋类企业低价竞销产生的原因及其危害性,并就如何解决这一问题进行了初步的探讨。     

碳排放约束视角下产业智能化对区域经济差距的影响研究

本文利用2003~2019年中国省级面板数据,从碳排放约束视角出发,实证考察了产业智能化对区域经济差距影响的差异性和产业智能化影响区域经济差距的机制。研究表明,产业智能化对缩小全国、东、中和西部地区省域间经济差距具有显著的正向效应;进一步考虑碳排放约束,发现碳排放约束正向调节了产业智能化对区域经济差距的正向效应,西部地区由于自身产业结构和区位因素,抑制了产业智能化对区域经济差距的正向效应;最后,对产业结构升级的两个子维度在产业智能化和区域经济差距间的中介效应检验,发现产业结构升级的中介效应存在,且主要是通过产业结构高级化实现,产业结构合理化发挥的作用较小。
