In order to reach climate goals, governments need to gain support from their voters for the necessary policy interventions, such as carbon dioxide taxes. Previous research concludes that people often do not support and legitimize such taxes because they perceive them as unfair. However, the notion of fairness implies a multitude of factors and despite attempts of the previous research to further nuance people’s fairness perceptions, we currently lack a more precise understanding of what people mean when they regard carbon taxes as unfair. In this article, we thoroughly investigate this problem by using original survey data from YouGov collected in the United States in 2018 and analyzing open-ended survey responses on why people think carbon taxes are unfair. Applying structural topic modeling, we unpack the multi-dimensional meaning of unfairness, as perceived by the US population. The results from our analysis show that people regard carbon taxes based on gas pricing as unfair because they perceive gas prices already being high, because of the need to drive, unfairness for the poor or rural population, lack of trust in government, or considerations that the purpose of the tax is unjustified. These findings help provide a more nuanced policy design to address fairness concerns related to carbon taxes. 相似文献

科学设置碳税政策是控制二氧化碳排放量和推动能源结构优化的重要基础,文中以广东省为例,利用2012年的广东省投入产出表、广东统计年鉴、广东财政年鉴、中国统计年鉴等数据构建社会核算矩阵,通过构建静态的可计算一般均衡模型（CGE),进行区域的碳税政策模拟,分析不同程度的碳税税率对化石能源消费量及各宏观经济变量的影响。结果表明：征收碳税对减排效果有明显的正向作用,当碳税水平为60元/t时,广东省减排效果为3.90%;在碳税定价上,60元/t较为合适;减排贡献率最高的化石能源为煤炭,其次为石油,最低为天然气;碳税冲击下能源消费量下降,最明显的为煤炭,其次是火电;碳税冲击也能显著减少各部门对煤炭的消费量;碳税政策对广东省GDP和社会福利有负向作用,但对总体碳排放强度有正向作用。未来广东省应严格控制煤炭消费量,同时对火电部门进行低碳改造。 相似文献

More and more organizations are compensating the greenhouse gas emissions caused by their products and services through carbon offset programs. From the customers’ perspective, the mitigation of negative externalities associated with their demand may increase the utility derived from the (then guilt-free) consumption. In particular in settings where consumers do not pay for the marginal cost of consumption, this may lead to higher levels of resource use. This article empirically examines how the announcement of an organizational carbon offset program affects consumption in a CO2-intensive everyday activity (showering). We further evaluate the provision of real-time feedback as a strategy to counteract potential increases in consumption. For this purpose, we conducted an eight-week randomized controlled natural field experiment in a German youth hostel (full 2 × 2 factorial design; N = 9,999 observations). Consumption in the group with the offset program was statistically significantly higher than in the control group (by 5.4 to 15.5%). However, participants who additionally received real-time feedback on their consumption did not increase their resource use compared to the control group. While the results suggest that carbon offset programs may increase resource use, the findings provide evidence that organizations can counteract these adverse effects by making the individual’s resource use salient. 相似文献

The shift away from coal is at the heart of the global low-carbon transition. Can governments of coal-producing countries help facilitate this transition and benefit from it? This paper analyses the case for coal taxes as supply-side climate policy implemented by large coal exporting countries. Coal taxes can reduce global carbon dioxide emissions and benefit coal-rich countries through improved terms-of-trade and tax revenue. We employ a multi-period equilibrium model of the international steam coal market to study a tax on steam coal levied by Australia alone, by a coalition of major exporting countries, by all exporters, and by all producers. A unilateral export tax has little impact on global emissions and global coal prices as other countries compensate for reduced export volumes from the taxing country. By contrast, a tax jointly levied by a coalition of major coal exporters would significantly reduce global emissions from steam coal and leave them with a net sector level welfare gain, approximated by the sum of producer surplus, consumer surplus, and tax revenue. Production taxes consistently yield higher tax revenues and have greater effects on global coal consumption with smaller rates of carbon leakages. Questions remain whether coal taxes by major suppliers would be politically feasible, even if they could yield economic benefits. 相似文献

Greenhouse gas taxes on animal food products: rationale, tax scheme and climate mitigation effects 总被引：2，自引：2，他引：0
Agriculture is responsible for 25?C30% of global anthropogenic greenhouse gas (GHG) emissions but has thus far been largely exempted from climate policies. Because of high monitoring costs and comparatively low technical potential for emission reductions in the agricultural sector, output taxes on emission-intensive agricultural goods may be an efficient policy instrument to deal with agricultural GHG emissions. In this study we assess the emission mitigation potential of GHG weighted consumption taxes on animal food products in the EU. We also estimate the decrease in agricultural land area through the related changes in food production and the additional mitigation potential in devoting this land to bioenergy production. Estimates are based on a model of food consumption and the related land use and GHG emissions in the EU. Results indicate that agricultural emissions in the EU27 can be reduced by approximately 32 million tons of CO2-eq with a GHG weighted tax on animal food products corresponding to ?60 per ton CO2-eq. The effect of the tax is estimated to be six times higher if lignocellulosic crops are grown on the land made available and used to substitute for coal in power generation. Most of the effect of a GHG weighted tax on animal food can be captured by taxing the consumption of ruminant meat alone. 相似文献

Deforestation, the second largest source of anthropogenic greenhouse gas emissions, is largely driven by expanding forestry and agriculture. However, despite agricultural expansion being increasingly driven by foreign demand, the links between deforestation and foreign demand for agricultural commodities have only been partially mapped. Here we present a pan-tropical quantification of carbon emissions from deforestation associated with the expansion of agriculture and forest plantations, and trace embodied emissions through global supply chains to consumers. We find that in the period 2010–2014, expansion of agriculture and tree plantations into forests across the tropics was associated with net emissions of approximately 2.6 gigatonnes carbon dioxide per year. Cattle and oilseed products account for over half of these emissions. Europe and China are major importers, and for many developed countries, deforestation emissions embodied in imports rival or exceed emissions from domestic agriculture. Depending on the trade model used, 29–39% of deforestation-related emissions were driven by international trade. This is substantially higher than the share of fossil carbon emissions embodied in trade, indicating that efforts to reduce greenhouse gas emissions from land-use change need to consider the role of international demand in driving deforestation. Additionally, we find that deforestation emissions are similar to, or larger than, other emissions in the carbon footprint of key forest-risk commodities. Similarly, deforestation emissions constitute a substantial share (˜15%) of the total carbon footprint of food consumption in EU countries. This highlights the need for consumption-based accounts to include emissions from deforestation, and for the implementation of policy measures that cross these international supply-chains if deforestation emissions are to be effectively reduced. 相似文献

Greenhouse gas abatement policies will increase the demand for renewable sources of energy, including bioenergy. In combination
with a global growing demand for food, this could lead to a food-fuel competition for bio-productive land. Proponents of bioenergy
have suggested that energy crop plantations may be established on less productive land as a way of avoiding this potential
food-fuel competition. However, many of these suggestions have been made without any underlying economic analysis. In this
paper, we develop a long-term economic optimization model (LUCEA) of the U.S. agricultural and energy system to analyze this
possible competition for land and to examine the link between carbon prices, the energy system dynamics and the effect of
the land competition on food prices. Our results indicate that bioenergy plantations will be competitive on cropland already
at carbon taxes about US $20/ton C. As the carbon tax increases, food prices more than double compared to the reference scenario
in which there is no climate policy. Further, bioenergy plantations appropriate significant areas of both cropland and grazing
land. In model runs where we have limited the amount of grazing land that can be used for bioenergy to what many analysts
consider the upper limit, most of the bioenergy plantations are established on cropland. Under the assumption that more grazing
land can be used, large areas of bioenergy plantations are established on grazing land, despite the fact that yields are assumed
to be much lower (less than half) than on crop land. It should be noted that this allocation on grazing land takes place as
a result of a competition between food and bioenergy production and not because of lack of it. The estimated increase in food
prices is largely unaffected by how much grazing land can be used for bioenergy production. 相似文献

State and local governments in the USA are evaluating a wide range of policies to reduce carbon emissions, including carbon taxes, which have existed internationally for nearly 20 years. In this article, existing carbon tax policies, both internationally and in the USA, are reviewed, and carbon policy design and effectiveness are analysed. Design considerations include which sectors to tax, where to set the tax rate, how to use tax revenues, what the impact will be on consumers, and how to ensure that emissions reduction goals are achieved. Emissions reductions that are due to carbon taxes can be difficult to measure, although some jurisdictions quantify reductions in overall emissions, others examine impacts that are due to programmes funded by carbon tax revenues. 相似文献

This paper proposes a global warming implementation regime which addresses the issues of equity, flexibility, cost minimization, and population growth. Previously proposed international policy instruments, such as country by country targets, carbon taxes, and tradable permits, face major difficulties as stand alone proposals. The key element of the regime proposed here is to combine annual tradable permits which are allocated based on population in a fixed year with a small carbon tax ($5–10/tonne) on emissions in excess of permits. Both permits and carbon taxes are applied to national level governments, which in turn would use whatever mix of policies desired to reduce national emissions. It is suggested that the initial number of permits correspond to total global emissions in the base year; over time, the number of permits could be reduced and the tax rate increased if improved scientific knowledge so dictates. By allocating permits based on population the equity concerns of developing countries are addressed, while taxing emissions in excess of permit holdings removes the rigidity of a quota system and limits resource transfers by effectively capping the permit trading price, which is a major concern of industrialized countries. To accommodate the difficulties of countries which have not yet achieved the demographic transition, the permit allocation scheme could be subject to a one-time adjustment after 10–15 years based on some weighting of the initial and then-current populations. The proposed scheme is based on the premise that there is a large potential for reducing emissions in developed countries or limiting emission increases in developing countries, and the intention is to create competition between national level governments in implementing cost-effective emission reduction. 相似文献

Systematic evidence relating to the performance of carbon pricing – carbon taxes and greenhouse gas (GHG) emissions trading systems (ETSs) – is sparse. In 2015, 17 ETSs were operational in 55 jurisdictions while 18 jurisdictions collected a carbon tax. The papers in this special thematic section review the performance of many of these instruments over the 2005–2015 period. The performance of existing carbon taxes and GHG ETSs can help policy makers make informed choices about whether to introduce these instruments and to improve their design. The purpose of carbon pricing instruments is to reduce GHG emissions cost effectively. Assessing their performance is difficult because emissions are also affected by other policies and exogenous factors such as economic conditions. Carbon taxes in Europe prior to 2008 and in British Columbia reduced emissions from business-as-usual but actual emissions continued to rise. Since 2008 emissions subject to European carbon taxes have declined, but in most countries, other mitigation policies have probably contributed more to the reductions than the carbon taxes. Emissions subject to ETSs, with the exception of four systems without emissions caps, have declined. The ETSs contributed to the emissions reductions, but their share of the overall reduction is not known. Most tax rates are low relative to levels thought to be needed to achieve climate change objectives. Few jurisdictions regularly adjust their tax rates. All ETSs have accumulated surplus allowances and implemented measures to reduce these surpluses. The largest ETSs now specify annual reductions in their emissions cap several years into the future. Emissions trading system allowance prices are generally lower than the tax rates.
Key policy insights
Theoretical discussions usually portray carbon taxes and GHG ETSs as alternatives. In practice, a jurisdiction often implements both instruments to address emissions by different sources.
Designs of ETSs have evolved based on experience shared bilaterally and via dedicated institutions.
Carbon tax designs, in contrast, have hardly evolved and there are no institutions dedicated to sharing experience.
Every jurisdiction with an ETS and/or carbon tax also has other policies that affect its GHG emissions.

Transportation contributes to a significant and rising share of global energy use and GHG emissions. Therefore modeling future travel demand, its fuel use, and resulting CO2 emission is highly relevant for climate change mitigation. In this study we compare the baseline projections for global service demand (passenger-kilometers, ton-kilometers), fuel use, and CO2 emissions of five different global transport models using harmonized input assumptions on income and population. For four models we also evaluate the impact of a carbon tax. All models project a steep increase in service demand over the century. Technology change is important for limiting energy consumption and CO2 emissions, the study also shows that in order to stabilise or even decrease emissions radical changes would be required. While all models project liquid fossil fuels dominating up to 2050, they differ regarding the use of alternative fuels (natural gas, hydrogen, biofuels, and electricity), because of different fuel price projections. The carbon tax of 200 USD/tCO2 in 2050 stabilizes or reverses global emission growth in all models. Besides common findings many differences in the model assumptions and projections indicate room for further understanding long-term trends and uncertainty in future transport systems. 相似文献

Many European politicians argue that the EU should set tougher emission targets than what is required by the Kyoto protocol,
and moreover, that emission trading with other countries outside EU should be limited so as to keep emission quota prices
high. One of the arguments, frequently cited for such a policy, is the need for technological development. However, the literature
on climate change and technological innovation does not unambiguously support the need for setting high emission taxes today.
In this paper we investigate the relationship between emission taxes and technological change further by modeling innovation
activity explicitly. In our model both the amount of R&D and the amount of carbon abatement are decided in a decentralized
way by the market as a response to an emission tax. Moreover, we introduce several distinct failures in the market for new
innovations, among others, insufficient patent protection and intertemporal knowledge spill-overs. Our findings suggest that
governments should under some circumstances set a higher carbon tax today if we have technological change driven by R&D than
if we have pure exogenous technological change. Based on numerical simulations these circumstances are (a) positive intertemporal
knowledge spillovers and/or (b) weak patent protection. 相似文献

Carbon pricing, including carbon taxes and emissions trading, has been adopted by different kinds of polities worldwide. Yet, beyond the increasing adoption over time, little is known about what polities – countries as well as sub- and supranational entities – adopt carbon pricing and why. This paper explores patterns of adoption (both implemented policies and those scheduled to be) through cluster analysis, with the purpose of investigating factors that could explain polities’ decisions to adopt carbon pricing. The study contributes empirically by studying carbon taxes and emissions trading together and by ordering the polities adopting carbon pricing into clusters. It also contributes theoretically, by exploring constellations of variables that drive the adoption of carbon pricing within individual clusters. We investigated 66 adopted policies of carbon pricing, which were divided into five clusters: early adopters, North-American subnational entities, Chinese pilot provinces, second-wave developed polities, and second-wave developing polities. The analysis indicates that the reasons for adopting carbon pricing have shifted over time. While international factors (climate commitments or influences from polities within the same region) are increasingly salient, domestic factors (including crises and income levels) were more important for the early adopters.
Key policy insights
Carbon pricing has become a global mainstream policy instrument.
Economic and fiscal crises provide windows of opportunity for promoting carbon pricing.
The international climate regime can support the adoption of carbon pricing through mitigation commitments and international financial and technical assistance.
Learning between polities from the same region is a useful tool for promoting carbon pricing.
Carbon intensive economies tend to prefer emissions trading over carbon taxes.

The fact that developing countries do not have carbon emission caps under the Kyoto Protocol has led to the current interest in high income countries in border taxes on the ‘virtual’ carbon content of imports. We use GTAP data and input-output analysis to estimate the flows of virtual carbon implicit in domestic production technologies and the pattern of international trade. The results present striking evidence on the wide variation in the carbon-intensiveness of trade across countries, with major developing countries being large net exporters of virtual carbon. Our analysis suggests that a tax on virtual carbon could lead to very substantial effective tariff rates on the exports of the most carbon-intensive developing nations. As an illustration, we find that average tariff rates of 10%, 8% and 12% would be faced by imports from China, India and South Africa if carbon is taxed at $50/ton CO2. Moreover, there is wide variation in intensiveness across sectors within countries with implications for the disparate effective tariff burdens on particulars parts of the economies of these countries. Such empirical findings, we argue, are useful for framing on-going discussions about the principles and practice of border taxes on virtual carbon. 相似文献

This study aims at better understanding how, and to what extent, perceptions of a policy instrument’s distributional effects impact on policy support, focusing on the case of CO2 taxes on petrol in Sweden. Through a large-scale (N?=?5000) randomized survey experiment with a 2?×?3 factorial design, the extent to which perceptions of fairness determine attitudes to a suggested increase of the Swedish CO2 tax is explored. Furthermore, the study considers whether these effects change with the level of the suggested tax increase, as well as whether negative sentiments can be alleviated by combining it with a compensatory measure in the shape of a simultaneous income tax cut financed by the revenues from the tax increase. The results show that a higher tax increase is both viewed as more unfair and enjoys weaker support. Furthermore, compensatory measures can be a powerful policy design tool to increase perceptions of the policy as fair, but the effect of compensation on policy support is conditioned by the individual’s left–right ideological position. Whereas people self-identifying to the right react favourably to compensatory measures, people self-identifying to the left become less supportive of a tax increase when combined with a simultaneous cut in income taxes.Key policy insights
Perceptions of fairness are highly important for explaining public support for climate policy tools, specifically CO2 taxes.
Compensatory measures can be a powerful policy design tool to increase perceptions of the policy as less unfair.
However, the effect of compensatory measures on policy support is conditioned by ideological position, and only successful among people to the ideological right.
In contexts dominated by right-wing ideals, a combination of a tax and a compensatory scheme may be a successful route forward towards increased climate policy support.
In left-oriented contexts the results imply that a CO2 tax without compensation seems more likely to increase support.

碳关税是各国高度关注的贸易问题,因涉及各国经贸利益,南北国家在碳关税问题上分歧很大。任何有关碳关税的政策措施,都会引起发展中国家的强烈反对。因此,部分发达国家试图另辟蹊径,在国际贸易中通过增加生产标准、碳标签等技术要求,以比较隐蔽的方式实现执行碳关税的目的。文中将这些隐蔽的但能起到碳关税执行效果的政策措施归纳为隐形碳关税,并定义隐形碳关税是指那些虽然没有在边境环节征收碳关税,但与征收碳关税起到相同贸易壁垒作用的,对发展中国家出口产品和服务构成限制的政策和措施。隐形碳关税比较典型的表现形式包括生产标准、碳标签等措施。这些措施本身是政策中性的,并不构成隐形碳关税,但如果叠加了转移应对气候变化成本、限制发展中国家产业发展等目的,这些措施的性质便不再中性,而成为现实中的贸易壁垒。隐形碳关税的治理应该是国际气候治理进程的一个部分,《联合国气候变化框架公约》则应是隐形碳关税治理的主要国际平台。无论是在气候公约内还是气候公约外的治理机制,隐形碳关税的国际治理都应遵循气候公约的相关原则,尤其是共同但有区别责任原则,区别对待发达和发展中国家的责任和义务,充分发挥生产标准、碳标签等措施的积极环境效用,同时约束其不当使用,建立公平、互信、务实的国际合作模式,实现气候治理与经济发展的协同。 相似文献

Exploring the environmental impact of dietary consumption has become increasingly important to understand the carbon-water-food nexus, vital to achieving UN sustainable development goals. However, the research on diet-based nexus assessment is still lacking. Here, we developed an Environmentally Extended Multi-Regional Input-Output (EE-MRIO) model with compiling a global MRIO table based on the latest Global Trade Analysis Project (GTAP) 10 database, where we specifically constructed a water withdrawal account and matched it to each economy at the sectoral level. The regional heterogeneity and synergy of carbon-water nexus affected by dietary patterns in nine countries was explored. The results show that: (1) Dietary consumption is the main use of water withdrawal for each country; Japan, the US, South Korea, and India have a high per capita dietary water footprint. Mainly due to consumption of processed rice, Japan has the highest per capita value of 488 M3/year, accounting for 63.4% of the total water footprint. (2) The total dietary carbon footprints in China, India, and the US are high, which is mainly caused by the high consumption of animal products (including dairy) either due to the large population (China, India) or animal-based diet (the US). Americans have the highest per capita dietary carbon footprint, reaching 755.4 kg/year, 2.76 times that of the global average. (3) Generally, imported/foreign footprints account for a greater share in dietary water and carbon footprints of developed countries with an animal-based diet. (4) In the nexus analysis, the US, Japan, and South Korea are key-nexus countries, vegetables, fruit and nuts, tobacco and beverages, and other food products are selected as key-nexus sectors with relatively high dietary water and carbon footprint. Furthermore, dietary consumption choices lead to different environmental impacts. It is particularly important to find a sustainable dietary route adapted to each country considering that heterogeneity and synergism exist in key-nexus sectors to achieve the relevant Sustainable Development Goals. 相似文献

Introducing a carbon tax is difficult, partly because it suggests that current generations have to make sacrifices for the benefit of future generations. However, the climate change externality could be corrected without such a sacrifice. It is possible to set a carbon value, and use it to create ‘carbon certificates’ that can be accepted as part of commercial banks’ legal reserves. These certificates can be distributed to low-carbon projects, and be exchanged by investors against concessional loans, reducing capital costs for low-carbon projects. As the issuance of carbon certificates would increase the quantity of money, it will either lead to accelerated inflation or induce the Central Bank to raise interest rates. Low-carbon projects will thus have access to cheaper loans at the expense of either ‘regular’ investors (in case of higher interest rates) or of lenders and depositors (in case of accelerated inflation). Within this scheme, mitigation expenditures are compensated by a reduction in regular investments, so that immediate consumption is maintained. It uses future generation wealth to pay for a hedge against climate change. This framework is not as efficient as a carbon tax but is politically easier to implement and represents an interesting step in the trajectory towards a low-carbon economy. 相似文献
