State and local governments in the United States are evaluating a wide range of policies to reduce carbon emissions, including, in some instances, carbon taxes, which have existed internationally for nearly 20 years. This report reviews existing carbon tax policies both internationally and in the United States. It also analyzes carbon policy design and effectiveness. 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 emissions reduction goals are achieved. Emission reductions that are due to carbon taxes can be difficult to measure, though some jurisdictions have quantified reductions in overall emissions and other jurisdictions have examined impacts that are due to programs funded by carbon tax revenues.

Publisher Copyright: © 2022 The Authors We use station-level price data and a significant diesel fuel carbon tax reform to study who bears the economic burden of fuel carbon taxes. We use a difference-in-differences strategy to estimate the pass-through of the large carbon tax increase to retail prices, where we compare retail diesel prices faced by private motorists to retail gasoline prices. We find that on average fuel carbon taxes are less than fully passed through to consumer prices, which suggests that consumers and the supply chain split the burden of these taxes. Using information on station location, we match price observations with postcode-level average incomes and measures of urbanization, and show that there are significant differences in the pass-through rate across areal incomes and between rural and urban areas up to one year after the reform. The effect of fuel carbon taxes on consumer prices decreases with areal income and with the degree of urbanization. Peer reviewed

This article examines the role of environmental taxation in mitigating environmental problems and contributing to sustainability in Mexico. It focuses on environmental tax revenues and tax expenditures since the 2014 Public Financial Reform (PFR), according to pro- or anti-environmental orientation. The research carried out combines the study of the regulation of the selected tax instruments, their classification and the empirical analysis of the tax revenues and tax expenditures associated with the different taxes over the periods of validity of the taxes and benefits studied, using the databases of the CIAT and the Mexican SHCP. A critical analysis addresses the weak environmental function of environment-related taxes (IEPS, ISAN…), as well as the late implementation and reduced impact of the carbon and pesticide taxes introduced in 2014. The evolution of tax incentives and expenditure is thoroughly examined by examining both environmental measures, which have evolved positively but within a very reduced level, and the most prevalent tax expenditure measures, with harmful impacts to the environment. Based on the results obtained, long-term structural changes in the Mexican tax system are suggested. As for the short to medium term, profound changes in tax expenditure are proposed to eliminate of those tax benefits harmful to the environment, introduce of tax benefits for circular activities (e.g., repairing, reusing and remanufacturing) and broaden the carbon tax base and rates. The conclusions include recommendations for moving towards a systemic green tax reform that assists the transformation towards a sustainable economy.

This article explores the links between energy policy, tax policy and global warming. This article focuses on tax policy, because the emerging consensus among legal scholars favors economic incentives rather than command-and-control regulations for reaching environmental goals, and the Federal income tax has proved an effective delivery system for economic incentives. After briefly discussing of the science of global warming and the provisions of the Kyoto Protocol on Climate Change, the article reviews the impact of both existing tax law and current proposals for energy legislation on global warming, as well as potential international law consequences of failure to act to curtail global warming. This analysis also includes a discussion of global warming as "tragedy of the commons" issue and reflects on how psychological factors and economic beliefs may affect the public's level of concern about global warming. Concluding that both present law and current proposals create incentives for continued and increasing use of greenhouse gas emitting fossil fuels, the article outlines a three part strategy for curtailing global warming through tax policy: (1) reducing or eliminating the present law subsidies for fossil fuel use while creating and strengthening incentives for alternative energy generation; (2) imposing a carbon tax; and (3) creating incentives for development of carbon sequestration projects in privately held forests in the United States. The article studies the effectiveness of these proposals by comparing similar proposals in effect in other countries and by considering the classic tax policy goals of equity and efficiency. The tax system is an appropriate and effective way to encourage businesses to adopt an environmental ethic and take action to reverse global warming. Strong economic, esthetic, and moral arguments support changing our tax system to protect the environment from global warming.

This review paper highlights the informational requirements for the effective use of environmental policy instruments to achieve ambient standards of pollution in India. A section on the Integrated Urban Air Pollution Assessment Model is attempted to identify data requirements for, and information gaps associated with, using these instruments. We review the available information and identify informational gaps that thwart the realization of ambient standards of environmental quality. In India, command-and-control instruments are arbitrarily used to assign liability without taking cognizance of economic estimates. The available cost–benefit estimates of air and water pollution, combined with air quality modelling for urban areas and water quality modelling, are essential inputs for using environmental policy instruments to ensure compliance with ambient standards. We discuss how to use economic estimates while designing and using economic instruments such as pollution taxes and pollution permits, in addition to command and control.

This paper takes a dive into the deep literature on the carbon tax accumulated through active and continuous research over the past 30 years. It also presents the ongoing debate and implementation of the carbon tax in practice. The paper discusses the evolution of the carbon tax literature, classifying it by the issues investigated and methodology used for the investigation. It finds that the literature enlightens four key issues: (i) economic impacts, (ii) choices for revenue recycling, (iii) distributional implications, and (iv) competitiveness and border tax adjustment. Quantitative analysis, especially computable general equilibrium modeling, is the main method employed in the literature. The study shows that potential adverse economic impacts and competitiveness concerns are the main impediments to the introduction of the carbon tax. Extensive examinations of carbon tax issues at the global, regional, and country levels have led to innovative measures to address these concerns. While the carbon tax was mainly a subject of academic discussion until few years back, it has generated good attention for policy makers, particularly after the Paris Agreement on climate change, and is being considered as one of the main market instruments to address global climate change. Although several important issues related to the carbon tax have been well researched, its potential interactions with poverty and shared prosperity are yet to be investigated.

Air transport has become a vital component of the global economy. However, greenhouse-gas emissions from this sector have a significant impact on global climate, being responsible for over 3.5% of all anthropogenic radiative forcing. Also, the accrued visibility of aircraft emissions greatly affects the public image of the industry. In this context, incentive-based regulations, in the form of price or quantity controls, can be envisaged as alternatives to mitigate these emissions. The use of environmental charges in air transport, and the inclusion of the sector in the European Union Emissions Trading Scheme (EU ETS), are considered under a range of scenarios. The impacts of these measures on demand are estimated, and results suggest that they are likely to be minimal—mainly due to the high willingness to pay for air transport. In particular, in the EU ETS scenario currently favoured by the EU, demand reductions are less than 2%. This may not be true in the longer run, for short trips, or if future caps become more stringent. Furthermore, given current estimates of the social cost of CO2 as well as typical EU ETS prices, supply-side abatement would be too costly to be encouraged by these policies in the short term. The magnitude of aviation CO2 emissions in the EU is estimated, both in physical and monetary terms; the results are consistent with Eurocontrol estimates and, for the EU-25, the total social cost of these emissions represents only 0.03% of the region's GDP. It is concluded that the use of multisector policies, such as the EU ETS, is unsuitable for curbing emissions from air transport, and that stringent emission charges or an isolated ETS would be better instruments. However, the inclusion of aviation in the EU ETS has advantages under target-oriented post-2012 scenarios, such as policy-costs dilution, certainty in reductions, and flexibility in abatement allocation. This solution is also attractive to airlines, as it would improve their public image but require virtually no reduction of their own emissions, as they would be fully capable of passing on policy costs to their customers.
