Subject Prospects for the introduction of a global carbon tax. Significance The decline in oil prices offers an opportunity to countries to introduce a carbon tax to reduce greenhouse gas emissions and combat climate change. The UN Climate Change Conference (COP 21), to be held in Paris in November and December, will seek a global agreement to reduce greenhouse gas emissions and set a specific goal to achieve net zero emissions by a certain date. Yet there is little clarity on how this goal could be achieved and whether there will be agreement on setting a price for carbon. Impacts The oil price plunge will continue to divert attention away from the need to reduce reliance on fossil fuels and increase energy efficiency. Without a credible agreement at COP 21, containing climate change disruption will be difficult. For any climate agreement to be credible, its implementation process must be addressed in detail.

Double Exponential Smoothing

Purpose The purpose of this paper is to predict the amount of energy consumption by using a suitable statistical method in some sectors and energy carriers, which has shown a significant correlation with greenhouse gas emissions. Design/methodology/approach After studying the correlation between energy consumption rates in different sectors of energy consumption and some energy carriers with greenhouse gas distribution (CO2, SO2, NOX and SPM), the most effective factors on pollution emission will be first identified and then predicted for the next 20 years (2015 to 2004). Furthermore, to determine the appropriate method for forecasting, two approaches titled “trend analysis” and “double exponential smoothing” will be applied on data, collected from 1967 to 2014, and their capabilities in anticipating will be compared to each other contributing MSD, MAD, MAPE indices and also the actual and projected time series comparison. After predicting the energy consumption in the sectors and energy carriers, the growth rate of consumption in the next 20 years is also calculated. Findings Correlation study shows that four energy sectors (industry sector, agriculture, transportation and household-general-commercial) and two energy carriers (electricity and natural gas) have shown remarkable correlation with greenhouse gas emissions. To predict the energy consumption in mentioned sectors and carriers, it is proven that double exponential smoothing method is more capable in predicting. The study shows that among the demand sectors, the industry will account for the highest consumption rate. Electricity will experience the highest rate among the energy careers. In fact, producing this amount of electricity causes emissions of greenhouse gases. Research limitations/implications Access to the data and categorized data was one of the main limitations. Practical implications By identifying the sectors and energy carriers that have the highest consumption growth rate in the next 20 years, it can be said that greenhouse gas emissions, which show remarkable correlation with these sectors and carriers, will also increase dramatically. So, their stricter control seems to be necessary. On the other hand, to control a particular greenhouse gas, it is possible to focus on the amount of energy consumed in the sectors and carriers that have a significant correlation with this pollutant. These results will lead to more targeted policies to reduce greenhouse gas emissions. Social implications The tendency of communities toward industrialization along with population growth will doubtlessly lead to more consumption of fossil fuels. An immediate aftermath of burning fuels is greenhouse gas emission resulting in destructive effects on the environment and ecosystems. Identifying the factors affecting the pollutants resulted from consumption of fossil fuels is significant in controlling the emissions. Originality/value Such analyses help policymakers make more informed and targeted decisions to reduce greenhouse gas emissions and make safer and more appropriate policies and investment.

Purpose The purpose of this paper is to highlight the opportunity for the energy policy in Brazil to tackle the very high cost-effectiveness potencial of solar energy to the power system. Three mechanisms to achieve ambitious reductions in the greenhouse gas emissions from the power sector by 2030 and 2040 are assessed wherein treated as solar targets under ambitious reductions in the greenhouse gas emissions from the power sector. Then, three mechanisms to achieve these selected solar targets are suggested. Design/methodology/approach This paper reviews current and future incentive mechanisms to promote solar energy. An integrated energy system optimization model shows the most cost-efficient deployment level. Incentive mechanisms can promote renewable sources, aiming to tackle climate change and ensuring energy security, while taking advantage of endogenous energy resources potential. Based on a literature review, as well as on the specific characteristics of the Brazilian power system, under restrictions for the expansion of hydroelectricity and ambitious limitation in the emissions of greenhouse gases from the power sector. Findings The potential unexploited of solar energy is huge but it needs the appropriate incentive mechanism to be deployed. These mechanisms would be more effective if they have a specific technological and temporal focus. The solar energy deployment in large scale is important to the mitigation of climate change. Originality/value The value of the research is twofold: estimations of the cost-effective potential of solar technologies, generated from an integrated optimization energy model, fully calibrated for the Brazilian power system, while tacking the increasing electricity demand, the expected reduction of greenhouse gas emissions and the need to increase the access to clean and affordable energy, up to 2040; proposals of three mechanisms to deploy centralized PV, distributed PV and solar thermal power, taking the best experiences in several countries and the recent Brazilian cases.

Significance The Paris Agreement will enter into force on November 4, ahead of the UN Framework Convention on Climate Change (UNFCCC) annual Conference of Parties (COP22) meeting in Marrakech, Morocco, which begins the following week. The two thresholds for entry into force -- more than 55 countries ratifying, accounting for 55% of global greenhouse gas emissions -- were met in early October. Impacts Activist states will continue to advance Paris-complementary measures in non-UNFCCC settings. The Paris Agreement's entry into force means that a signatory government can only withdraw in four years' time. However, a national leader willing to bear the diplomatic fallout could nevertheless undermine the pact through inaction and backsliding. The natural gas sector is a likely beneficiary of incremental international emissions reduction efforts.

Climate change is a serious threat to sustainability. Anthropogenic climate change is due to the accumulation of greenhouse gases (GHG) in the atmosphere beyond natural levels. Anthropogenic GHG emissions are mostly associated with carbon-dioxide (CO2) originated in the combustion of fossil fuels used for heat, power, and transportation. Globally, transportation contributes to 14% of the global GHG emissions. The transport sector is one of the main contributors to the greenhouse gas emissions of Ecuador. In Guayaquil, the road mass transportation system comprises regular buses and the bus rapid transit (BRT) system. Electricity in Ecuador is mostly derived from hydropower, hence incurs relatively low GHG emissions along its life cycle. Therefore, electrification of transport has been seen as an opportunity for mitigation of GHG emissions. In this study, the effect of partial replacement of the bus rapid system fleet is investigated. Feeders have been chosen as the replacement target in five different scenarios. GHG emissions from diesel-based feeders have been calculated using the GREET Fleet Footprint Calculator tool. The GHG emissions associated with the electricity used for transportation is calculated using the life cycle inventory of the electricity generation system of Ecuador. Three energy mix scenarios are used for this purpose. The 2012 mix which had 61% hydropower; the mix of 85% hydropower and the marginal electricity scenario, which supposed the extreme case when the new demand for electricity occurs during peak demand periods. Results indicate that mitigation of GHG emissions is possible for almost all scenarios of percentage fleet replacement and all mix scenarios. Electric buses efficiency and the carbon intensity of the electricity mix are critical for GHG mitigation.

The 2007 Bali conference heard repeated calls for reductions in global greenhouse gas emissions of 50 per cent by 2050 to avoid exceeding the 2°C threshold. While such endpoint targets dominate the policy agenda, they do not, in isolation, have a scientific basis and are likely to lead to dangerously misguided policies. To be scientifically credible, policy must be informed by an understanding of cumulative emissions and associated emission pathways. This analysis considers the implications of the 2°C threshold and a range of post-peak emission reduction rates for global emission pathways and cumulative emission budgets. The paper examines whether empirical estimates of greenhouse gas emissions between 2000 and 2008, a period typically modelled within scenario studies, combined with short-term extrapolations of current emissions trends, significantly constrains the 2000–2100 emission pathways. The paper concludes that it is increasingly unlikely any global agreement will deliver the radical reversal in emission trends required for stabilization at 450 ppmv carbon dioxide equivalent (CO 2 e). Similarly, the current framing of climate change cannot be reconciled with the rates of mitigation necessary to stabilize at 550 ppmv CO 2 e and even an optimistic interpretation suggests stabilization much below 650 ppmv CO 2 e is improbable.

The effects on the environment as a consequence of climate change are severe, especially the problem causing from anthropogenic greenhouse gas emissions. It is necessary to internalize these external costs caused by human activities. Taxes should be levied on polluters so as to reduce pollutions. Thus, accompanying with appropriate complementary measures and policies, carbon taxes are effective to mitigate emissions of CO2. Meanwhile, the carbon tax system in British Columbia, Canada achieves notable effectiveness, is worth further studying and analyzing, and can become a model for Taiwan.

‘Solutions’ examines three types of solution to climate change. The first is adaptation, which is simply providing protection for the population, as we already know that there will be climate change even if emissions are radically cut back to 1990 levels. Second is mitigation, which would involve cutting our carbon footprint and thus reversing the trend that currently exists of ever increasing greenhouse gas emissions. Fossil fuels need to be replaced with renewable or alternative energy sources that will not produce greenhouse gas emissions. Third is geoenginnering that involves large-scale extraction of carbon dioxide from the atmosphere or modification of the global climate.

The introduction provides an overview of the argument of the book that climate change has real costs we are paying right now. Greenhouse emissions are changing our climate and our current policies are inadequate to the task of reducing greenhouse gas emissions. A carbon tax uses the power of the market to reduce emissions without onerous regulations. It uses the power of market forces to reduce emissions without burdening businesses with paperwork and red tape. As such, it should have bipartisan appeal.

Norway was the first country in the world to fix a carbon dioxide target. Norway was also one of the first countries to implement taxes to increase incentives to reduce greenhouse gas emissions. The aim of the paper is to analyse the role of environmental taxes in Norwegian climate policy. The author also examines the differences between the climate change policy measures in Norway and in the European Union countries, especially Poland.The first part of the paper contains an analysis of data on greenhouse gas emissions in Norway in the years 1990-2011. In the further sections of the paper the discussion is focused on the characteristics of Norwegian tax system and design of taxes used in Norway as instruments for addressing climate change. Particular attention is paid to the carbon tax, in force since 1991. The tax is responsible for large CO2 emission reductions. The paper is largely based on review of various reports, literature and websites on climate change policy, energy policy and transport policy in Norway.

Even though the contribution of the aviation sector to the global economy is very notable, it also has an adverse impact on climate change. Improvements have been made in different areas (i.e., technology, sustainable aviation fuel, and design) to mitigate these adverse effects. However, the rate of improvement is small compared to the increase in the demand for air transportation. Hence, greenhouse gas emissions in the aviation sector are steadily increasing and this trend is expected to continue unless adequately addressed. In this context, this study examined the following: (i) the factors that affect the growth of aviation, (ii) trends in greenhouse gas emissions in the sector, (iii) trends in energy demand, (iv) mitigation pathways of emissions, (v) mitigation challenges for the International Civil Aviation Organization, (vi) achievements in mitigating emissions, (vii) barriers against mitigating emissions, and (viii) approaches of overcoming barriers against emissions mitigation. This study finds that continued research and development efforts targeting aircraft fuel burn efficiency are crucial in reducing greenhouse gas emissions. Although biofuels are promising for the reduction of aviation emissions, techniques to reduce NOx emissions could enhance large-scale deployment. Pragmatic market-based mechanisms, such as the Emissions Trading Scheme (ETS) and/or carbon tax must be enforced on a global scale to capitalize on a collective stakeholder effort to curb CO2 emissions. The findings of this study will help in understanding the emissions and energy consumption scenarios, which will provide a comprehensive package of mitigation pathways to overcome future emissions reduction challenges in the aviation sector.
