This study estimated greenhouse gas emissions from aviation transportation and sought systems that could manage these emissions based on the IPCC guidelines to prepare for greenhouse gas regulations on international airlines. For this purpose, policies to reduce greenhouse gas emissions from aviation transportation were developed based on international agreements and the cases of advanced countries. In addition, marginal abatement costs and greenhouse gas reduction measures were derived for the effective execution of these policies. While estimating greenhouse gas emissions from aviation transportation, it was found that there has been an average increase of 3.9% and 12.9% for domestic and international flights, indicating that it is urgent that we prepare global greenhouse gas regulations. The estimated marginal abatement cost of greenhouse gas from airplanes was approximately. USD 123, and this amount could be used to decide the price of emission rights, the amount of carbon tax, and could be referred to when distributing incentives for voluntary agreements.

The measures to reduce greenhouse gas emissions for aviation transportation were classified into four types: voluntary agreements, international collaboration, greenhouse gas reduction technology and operation process development, and application of emission trading and carbon tax.

The purpose of this paper is to suggest an approach to post‐Kyoto climate negotiations that could provide a way out of the apparent deadlock between developed and developing countries. This is an urgent issue as the world already appears to be close to a level of climate change that could be considered “dangerous”.

The paper explores the potential that control of short‐lived greenhouse gases such as methane, tropospheric ozone, and soot could have, in addition to steep cutbacks in industrialized nations, to both mitigate global warming and overcome political stalemate in the international climate negotiations.

Although rarely mentioned in climate discourse, reducing emissions of short‐lived greenhouse gases offers a cost‐effective way of actually reducing the radiative forcing in the atmosphere, while at the same time producing substantial subsidiary benefits such as improved urban air quality. The paper suggests leveraging this potential in the post‐Kyoto treaty in order to “buy time” to address the arguably more difficult problem of essentially eliminating fossil‐fuel related CO₂ emissions, which will ultimately be required to truly bring climate change under control. While high‐income countries work on steep cutbacks of all greenhouse gas emissions, middle‐income nations could make significant additional contributions by undertaking commitments to control only short‐lived greenhouse gases until they reached a threshold level of per‐capita GDP, at which point they would cap and begin reducing all greenhouse gas emissions.

This paper recognizes that political tradeoffs will have to be made in negotiating the next climate treaty, and offers a way of approaching these tradeoffs that could minimize resulting environmental damage.

The purpose of this paper is to outline the cause of global warming, its trends and consequences as indicated by the International Panel on Climate Change. Sea‐level rise is one consequence of particular concern to Pacific Island states. It also reviews the views of economists about connections between economic growth and global warming.

International efforts, such as through the Kyoto protocol, to reduce greenhouse gas emissions and their atmospheric concentration are discussed and prospects for post‐Kyoto policies are considered. Ways are also examined of addressing the consequences of global warming for the Pacific Island states. How they will be affected and to what extent is discussed, together with their ability to cope with the emerging problem.

The paper finds that whereas the majority of economists did not foresee a conflict between economic growth and global warming, the possibility of such a conflict is now more widely recognized following the Stern Report. It is predicted that a significant reduction in global greenhouse gas emissions is unlikely to be achieved in the foreseeable future owing to conflicting national interest (a prisoners' dilemma problem) and because is will take time to develop new technologies which will reduce greenhouse gas emissions. However, payment for greenhouse gas emissions (for example, via tradable permits) will accelerate desirable technological advance. Both international political action and efforts to develop and use technologies that lower greenhouse gas emissions need to be pursued. Given current and likely increases in greenhouse gas emissions, continuing global warming in this century (and beyond) appears to be inevitable and consequently Pacific Island states will be adversely affected by sea‐level rise and climate change.

The paper emphasizes that Pacific Island states will suffer great hardship from global warming but are ill‐placed geographically, financially and administratively to prevent or adjust to the possible environmental disasters that await them. Nothing may save some from eventual environmental annihilation.

The paper is an excerpt from a more comprehensive study by the Florida Department of Environmental Protection comparing the technical elements of offset projects in forestry, agriculture, and waste management, as well as some miscellaneous project types. The authors compare and contrast design elements of three specific offset projects: afforestation/reforestation, manure management, and landfill gas capture. The technical review for each offset project is concluded with a look at the potential applicability for that project in Florida in the context of the protocols evaluated.

Offset projects that may be employed in Florida are first broken up into comparable design elements specific to the selected offset project type. Focusing on the design elements, a discussion of the similarities and differences among the protocols for each offset project is presented. Each section begins with general findings then moves on to assessments of the detailed design elements. Finally, the project's general applicability to Florida is considered, highlighting specific strengths of particular protocols from the analysis of the design elements.

Protocols tend to vary from highly specific requirements to a more general set of recommendations. Interestingly, no one program's set of protocols is the most opportunistic for Florida, but rather various protocols may have distinctive strengths depending on the project type.

Many comparative studies of offset protocols evaluate protocols in the context of program‐level policies. This study uniquely values the technical details in the protocols and does not consider policy or program‐level issues.

The purpose of this paper is to analyse the situation in Spain after the Kyoto Protocol with respect to greenhouse gas emissions and the national allocation plan published in 2005, which assigns CO₂ tonnes to approximately 1,920 Spanish firms for the 2005‐2007 period.

The author analysed the international norms related to the Kyoto Protocol and the situation in Spain.

From the conclusions of the study it can be derived that, although in recent years notable progress has been made, there is still a series of issues that can only be resolved, in the author's opinion, with practical application on the part of firms over time. These issues, both on an international level and in Spain, are: how to reflect the greenhouse gas emissions allowance in accounting; what information firms should include about greenhouse gas emissions in their annual reports; environmental reports and web sites; and what the economic impact of the Kyoto Protocol will be on the world economy, considering that some countries have already ratified it, while others have not.

This work should also be extended to more countries and not just be limited to Spanish companies. There is still much to be done to cover the possible gaps in this topic.

It is believed that the issues posed by the different sets of regulations are developing little by little, as seen in the fact that different countries are passing their respective national allocation plans, which specify the individual allocation of greenhouse gas emission allowances of different industries.

The purpose of this paper is to investigate the factors driving greenhouse gas reporting by Chinese companies.

Content analysis of annual reports and corporate social responsibility (CSR) reports for the year 2010 of the top 100 A‐share companies listed on Shanghai Stock Exchange was conducted to investigate the extent of greenhouse gas reporting. Multiple regression analysis was performed to determine the factors driving these companies' greenhouse gas reporting.

It was found that most Chinese companies reported neutral and good news. The results also indicate larger companies operating in an industry which has higher level of carbon dioxide emissions tend to have higher levels of greenhouse gas disclosures, consistent with the expectation of legitimacy theory. However, profitability and overseas listing were not significantly related to greenhouse gas reporting. This is consistent with the findings of previous literature. Finally, contrary to expectations, state‐owned companies report less greenhouse gas information than private companies.

The paper contributes towards theory development by testing legitimacy theory in the context of greenhouse gas reporting by Chinese companies and contributes to existing literature on greenhouse gas reporting by focussing on the large emerging economy of China. The practical contribution of the paper rests in the area of accounting practice. The results outline the dearth in greenhouse gas reporting by Chinese companies, suggesting there needs to be future development of accounting standards in this area.

The purpose of this study is to analyse different factors behind the disclosure of corporate information on issues related to greenhouse gas emissions and climate change world‐wide.

The empirical analysis carried out was performed in two stages: analysis of the data obtained through content analysis and analysis of the factors that influence the disclosure of greenhouse gas emissions and climate change using a dependency model, a multiple linear regression. Several variables were introduced to represent the size of the companies, leverage, return on assets (ROA), return on equity (ROE) and Market‐to‐Book ratio. Also, other dummy variables have been incorporated: Kyoto Protocol, activity sector in which the company operates and inclusion in the Dow Jones Sustainability Index.

The results obtained show a direct relationship between corporate size, its market capitalization and the disclosure of information in addition to proposed Global Reporting Initiative (GRI) indicators on greenhouse gas emissions. Conversely, an inverse relationship between ROE and disclosure is detected.

The findings emphasize that the main quoted companies operating in industries related to greenhouse gas emissions typically reveal information on almost all the GRI core indicators as well as the additional items specifically proposed for this issue. Moreover, the results suggest a trend for companies to utilize information on greenhouse gas emissions as a mechanism that enables them to legitimise themselves with those groups that can be of benefit to them.

The paper has analysed the disclosure of greenhouse gas emissions and other information of importance to climate change in companies from different countries, some of which have ratified, approved, adhered to or accepted the Kyoto Protocol, and some of which have still not accepted it.

Society has to find ways and means to reduce the emission of greenhouse gases, mainly carbon dioxide, to prevent global warming when considering inter‐generational equity with respect to environmental quality. The aim of the carbon dioxide emission control is to keep the level of carbon dioxide below a certain threshold level. This paper deals with the various policy instruments that are available to control greenhouse gases such as carbon dioxide. The criteria that should be used in selecting the appropriate policy instruments in controlling carbon dioxide emissions are: efficiency, equity and flexibility. Based on these criteria, the author is of the view that in the short‐run it is important for all the countries to ratify the Kyoto Protocol. However, in the long‐run, it may be possible to use the Kyoto targets to achieve an international carbon dioxide emission tradable permit system.

The purpose of this paper is to present greenhouse gas study results for biofuels produced with partial qualified utilisation of pulp wood or forest residues when integrated into kraft pulp mill systems. The impact of considering biogenic carbon on the results is also presented.

The material and energy balances of the integrated ethanol production were simulated for the study with a mill‐wide simulation model. Data for the simulation were obtained from prehydrolysis and cooking experiments. The life cycle model for greenhouse gas calculation was created based on the simulation results. In this paper, the change of forest carbon stock caused by residue removal from forest soil and carbon delay of forest growth after stand felling were also taken into consideration, to discuss the true greenhouse gas emissions of forest biomass utilisation.

The emission reduction levels achieved with these ethanol fuels derived from forest biomass ranged from 80 to 90 per cent when biogenic carbon emissions were neglected.

The findings indicate that in both cases a significant percentage of the side flows containing energy can be utilised to produce excess electricity when the ethanol plant is integrated into the pulp mill. The findings also indicate that the carbon storage impact of forest biomasses affects significantly the emission values of both studied fuels and overturns the emission savings of prehydrolysed chip based ethanol.

The purpose of this paper is to evaluate different greenhouse gas (GHG) mitigation policy instruments implemented in Slovenia, especially their impact on industrial competitiveness.

Analysis of existing mitigation policies.

The introduction of new policy instruments in Slovenia has not been very effective in curbing GHG emissions, but it certainly brought attention to the problem. As there is still a lot of space for improvements, additional effort should be made to improve existing instruments or to propose additional mitigation measures.

The paper evaluates existing policy instruments, which are still in their evolutional phases. The significance of this paper is to help to intensify indirect influence on GHG emissions reduction, especially on the national level, as proper introduction and understanding of the problem leads to more comprehensive and credible solutions regarding GHG emission reduction strategies. In addition, some new steps and/or measures are also indicated with this paper, especially concerning future evolution of EU emission trading scheme and national CO₂ tax regulation.

The paper is a new source of information about implementation of GHG mitigation policy measures in Slovenia. Analysis of adaptation and mitigation activities as well as integration of all aspects of climate change issues into strategies for sustainable development is of significant importance for the relevant decision makers – to monitor the impact of their own policies for domestic assessment purposes, that is to choose a policy strategy, to understand the implications of existing and alternative policy strategies, and to understand the joint interactions of multiple, individual policy strategies.
