Market-Based Greenhouse Gas Emission 
September 29, 2020 
Reduction Legislation: 108th through 116th 
Jonathan L. Ramseur 
Congresses 
Specialist in Environmental Policy 
Congressional interest in market-based greenhouse gas (GHG) emission control legislation has 
  
fluctuated over the past 15 years. During that time, legislation has often involved market-based approaches, such as a cap-and-trade system or a carbon tax or emissions fee program. Both 
 
approaches would place a price—directly or indirectly—on GHG emissions or their inputs, namely fossil fuels. Both would increase the price of fossil fuels , and both would reduce GHG emissions to some degree. Both would allow emission sources to choose the best way to meet their emission requirements or reduce costs, potentiallypotentialy by using market forces to minimize national costs of emission reductions. Preference between the two approaches ultimately depends on which variable policymakers prefer to precisely control—emission levels or emission prices. 
A primary policy concern with either approach is the economic impacts that may result. Expected energy price increases could have both economy-wide impacts (e.g., on the U.S. gross domestic product) and disproportionate effects on specific industries and particular demographic groups. The degree of these potential effects would depend on a number of factors, including the magnitude, design, and scope of the program and the use of tax or fee revenues or emission allowance values.
As the figurefigure below illustrates, between the 108th and 111th108th and 111th Congresses, most of the introduced bills would have established cap-and-trade systems. Between the 112th and 115th112th and 115th Congresses, most of the introduced bills would have established carbon tax or emissions fee programs. Most of the proposals from the 116th116th Congress would establish a carbon tax or emissions fee program. The proposals range in the scope of emissions covered from CO2CO2 emissions from fossil fuel combustion to multiple GHG GHG  emissions from a broader array of sources. In addition, the proposals differ by how, to whom, and for what purpose the fee revenues or allowance value would be applied. Some economic analyses indicate that policy choices to distribute the tax, fee, or emission allowance revenue would yield greater economic impacts than the direct impacts of the carbon price.

Market-Based Greenhouse Gas Emission Reduction Legislation 
 
Introduction Human activities, particularly fossil fuel combustion and industrial operations, have raised the atmospheric concentration of carbon dioxide (CO2CO2) and other greenhouse gases (GHGs)11 by about 40% over the past 150 years. Almost all al  climate scientists agree that these GHG increases have contributed to a warmer climate today and that, if they continue, they will wil  contribute to future climate change.22 Although a range of actions that seek to reduce GHG emissions are currently 
underway or being developed on the international3international3 and subnational level (e.g., individual state actions or regional partnerships),4,4 federal policymakers and stakeholders have different 
viewpoints over what to do, if anything, about future climate change and related impacts.
 
Congressional interest in GHG emission control legislation has fluctuated over the last 15 years. Proposals to limit GHG emissions have often focused on market-based approaches, such as a GHG emission cap-and-trade program or a GHG emissions tax (often referred to as a carbon tax) or fee.55 In general, a market-based approach would place a price on GHG emissions (e.g., through an emissions cap or emission tax or fee), allowingal owing covered entities to determine their pathway of compliance.6 
compliance.6 
This report provides a comparison of the legislative proposals from the 108th108th through the 116th 116th Congresses that were and are designed primarily to reduce GHG emissions using market-based 
approaches such as cap-and-trade or carbon tax/fee programs. During this time frame, Members introduced multiple energy-related proposals that would have likely resulted in reductions in GHG emissions—legislation that promotes renewable energy7 or encourages carbon capture and sequestration8—but these bills are not discussed in this report. 
In addition, starting in the 112th
                                              1 GHGs  in the atmosphere trap radiation as heat, warming the Earth’s surface and oceans. T he primary GHGs  emitted by human activities (and estimated by EPA in its annual inventories) include CO2, methane, nitrous oxide (N2O), sulfur hexafluoride (SF6), chlorofluorocarbons, hydrofluorocarbons (HFCs), and perfluorocarbons (PFCs). Other GHGs include  carbonaceous and sulfuric  aerosols, hydrochlorofluorocarbons, and elevated tropospheric ozone pollution generated by emissions of nitrogen oxides and  volatile organic compounds, such  as solvents.

3 Some countries have levied  carbon taxes (or something similar) for over 20 years. For a review of carbon prices in other countries, see OECD, Effective Carbon Rates: Pricing CO2 through Taxes and Em issions Trading System s, 2016, http://www.oecd-ilibrary.org/taxation/effective-carbon-rates_9789264260115-en; and the Carbon T ax Center website at http://www.carbontax.org/where-carbon-is-taxed. 
4 A number of U.S.  states have taken action requiring GHG  emission reductions. T he most aggressive actions have come from California and from the Regional Greenhouse  Gas  Initiative (RGGI)—a coalition of nine states from the Northeast and Mid-Atlantic regions. T he RGGI  is a cap-and-trade system that t ook effect in 2009 that applies to CO2 emissions from electric power plants. (See CRS  Report R41836, The Regional Greenhouse Gas Initiative: Background, Im pacts, and Selected Issues, by Jonathan L. Ramseur.) California established  a cap-and-trade program that took effect in 2013. California’s cap covers multiple GHGs,  which account for approximately 85% of California’s GHG  emissions. For more details, see  the California Air Resources  Board  website,  https://www.arb.ca.gov/cc/capandtrade/capandtrade.htm. In addition to its emissions cap, California has adopted a range of other climate change mitigation policies (e.g., renewable  energy portfolio stan dards).  5 Other approaches may include performance-based or technology-based standards (e.g., best available control technology). See CRS  Report R41973, Clim ate Change: Conceptual Approaches and Policy Tools, by Jane A. Leggett .  
6 T he 1990 Clean Air Act Amendments established  a market -based cap-and-trade program to control the air emissions (sulfur  dioxide and nitrogen oxides) that lead to acid rain. Although controversial at its inception, the progra m is widely considered  a success.  See,  for example, Gabriel  Chan et al., The SO2 Allowance Trading System  and the Clean Air Act Am endm ents of 1990: Reflections on Twenty Years  of Policy Innovation , Harvard Environmental Economics Program, 2012, https://www.belfercenter.org/sites/default/files/legacy/files/so2-brief_digital4_final.pdf.

GHG emissions—legislation that promotes renewable energy7 or encourages carbon capture and 
sequestration8—but these bil s are not discussed in this report.  
In addition, starting in the 112th Congress, some Members have introduced resolutions in the 
 Congress, some Members have introduced resolutions in the House and Senate expressing the view that a carbon tax is not in the economic interests of the United States. In September 2018, the House passed a resolution "“expressing the sense of Congress that a carbon tax would be detrimental to the United States economy" (” (H.Con.Res. 119).9
119).9 An analogous resolution was not introduced in the Senate in the 115th Congress. 
As Figure 1 illustrates, between the 108th and 111th115th Congress.  
As Figure 2 il ustrates, between the 108th and 111th Congresses, most of the introduced bills bil s would have established cap-and-trade systems. Between the 112th and 115th112th and 115th Congresses, most of 
the introduced billsbil s would have established carbon tax or emissions fee programs.
 
In the 111th111th Congress, Members offered multiple and varied proposals,1010 ultimately resulting in the House passage of H.R. 2454, an economy-wide cap-and-trade bill.11bil .11 A companion bill bil   in the Senate (S. 1733) was ordered reported from the Committee on Environment and Public Works, 
but the bill bil   was never brought to the Senate floor for consideration.
 
In subsequent Congresses, some Members continued to offer GHG emission control legislation, but these proposals saw minimal legislative   activity. During that time frame, the U.S. 
Environmental Protection Agency (EPA) used existing Clean Air Act authorities to promulgate GHG emission standards for key sectors, including the electric power and transportation sectors.12 12 EPA rulemakings in this area—particularly the 2015 Clean Power Plan final rule13rule13 and the 2019 
Affordable Clean Energy final rule14rule14—continue to generate interest and debate in Congress.
 
The proposals from the 116th116th Congress range in their scope of emissions covered from CO2 CO2 emissions from fossil fuel combustion to multiple GHG emissions from a broader array of sources. In addition, the proposals differ by how, to whom, and for what purpose the fee revenues or al owanceor allowance value would be applied. Some economic analyses indicate that policy choices to 
distribute the tax, fee, or emission allowanceal owance revenue would yield greater economic impacts than 
the direct impacts of the carbon price.
The first section of this report provides background information on cap-and-trade and carbon tax or emission fee programs. The second section compares the GHG emission reduction legislation in each Congress (108th-116th).
Over the last 15 years, broad GHG emission reduction legislation has generallygeneral y involved market-based approaches—such as cap-and-trade systems or carbon tax programs—that rely on private sector choices and market forces to minimize the costs of emission reductions and spur innovation.1516 Both carbon tax and emissions cap-and-trade programs would place a price—directly or indirectly—on GHG emissions or their inputs (e.g., fossil fuels), both wouldw ould increase the price of fossil fuels for the consumer, and both would reduce GHG emissions to some degree. 
Preference between the two approaches ultimately depends on which variable policymakers prefer to precisely control: emission levels or emission prices. As a practical matter, these market-based policies may include complementary or hybrid designs, incorporating elements to increase certainty in price or emissions quantity. For example, legislation could provide mechanisms for adjusting a carbon tax/fee if a targeted range of emissions reductions were not achieved in a given 
period. Alternatively,   legislation could include mechanisms that would bound the range of market 
prices for a cap-and-trade system'’s emissions allowancesal owances to improve price certainty.
 A GHG cap-and-trade system creates an overall overal  limit, or cap, on GHG emissions from certain sources. Cap-and-trade programs can vary by the sources covered, which often include major 
                                              16 In some instances, legislation would  have directed EPA to establish a GHG  emissions reduction program with a market -based approach as one option. An alternative approach to a market -based system might involve regulatory directives that require emission performance standards for specific sources  or the application of best available control technology.

emitting sectors (e.g., power plants and carbon-intensive industries), fuel producers and/or 
processors (e.g., coal mines or petroleum refineries), or some combination of both.
 
The emissions cap is partitioned into emission allowances. TypicallyTypical y, in a GHG cap-and-trade 
system, one emission allowanceal owance represents the authority to emit one metric ton16ton17 of carbon dioxide-equivalent (mtCO2e).17  (mtCO2e).18 The emissions cap creates a new commodity—the emission allowanceal owance. Policymakers may decide to distribute the emission allowancesal owances to covered entities at no cost (based on, for example, previous years'’ emissions), sell the allowancessel  the al owances (e.g., through an auction), or use some combination of these strategies. The distribution of emission allowances is typicallyal owances is 
typical y a source of significant debate during a cap-and-trade program'’s development, because the allowances
the al owances have monetary value.
 
At the end of each established compliance period (e.g., a calendar year or multiple years), 
covered sources submit emission allowancesal owances to an implementing agency to cover the number of tons emitted. If a source did not provide enough allowancesal owances to cover its emissions, the source would be subject to penalties. Covered sources would have a financial incentive to make reductions beyond what is required, because they could (1) sell sel  or trade unused emission allowancesal owances to entities that face higher costs to reduce their facility emissions, (2) reduce the 
number of emission allowanceal owance they need to purchase, or (3) bank them, if allowedal owed, to use in a 
future year. 
The use of emission offsets as a compliance option received attention during debate over cap-and-
trade programs. An offset is a measurable reduction, avoidance, or sequestration of GHG emissions from a source not covered by an emission reduction program. Economic analyses of cap-and-trade proposals concluded that offset treatment (i.e., whether or not to allowal ow their use and, if so, to what degree) would have a substantial impact on overall overal  program cost. This is because some emissions and sources often not covered in cap-and-trade programs can reduce 
emissions at a lower cost per ton than many typicallytypical y covered sources. However, the use of offsets generates considerable controversy, primarily over the concern that difficult-to-assess or 
fraudulent offsets could create uncertainty about the quantity of emission reductions.18
19 
In addition, other mechanisms—such as allowanceal owance banking or borrowing—may be included to 
increase the flexibility   of the program and, generallygeneral y, reduce the costs.
 In a carbon tax or emissions fee program, policymakers attach a price to GHG emissions or the inputs that create them. A carbon tax/fee on emissions or emissions inputs—namely fossil fuels—would increase the relative price of the more carbon-intensive energy sources. This result is 
                                              17 A metric ton is approximately 2,205 pounds. A short ton equals 2,000 pounds. 18 T his term of measure (CO2e) is  used  because  GHGs  vary by global  warming  potential (GWP). GWP is an index developed by the Intergovernmental Panel on Climate Change (IPCC) that allows comparisons of the heat -trapping ability of different gases over a period of time, typically 100 years. Consistent with international GHG reporting requirements, EPA’s most recent GHG  inventory (2018) uses the GWP values  presented in the IPCC’s 2007 Fourth Assessment Report. For example, based  on these GWP values, a ton of methane is 25 times more potent  than a ton of CO2 when averaged  over a 100-year time frame. T he IPCC has since updated the 100-year GWP estimates, with some increasing and some decreasing. For example, the IPCC 2013 Fifth Assessment Report reported the 100 -year GWP for methane as ranging from 28 to 36. EPA compares the 100-year GWP values in T able 1-3 of its 2018 GHG  Inventory. 
19 Both the RGGI  and California cap-and-trade systems allow  offsets as a compliance option (see footnote 4).

would increase the relative price of the more carbon-intensive energy sources. This result is expected to spur innovation in less carbon-intensive technologies and stimulate other behavior 
that may decrease emissions.19 
20 
Economic modeling indicates that a carbon tax/fee approach could achieve emission reductions, 
the level of which would depend on the scope and stringency (i.e., tax or fee level) of the program.2021 For example, to address emissions from fossil fuel combustion—76% of total U.S. GHG emissions22GHG emissions21—policymakers could apply a tax/fee to fossil fuels at approximately 3,000 entities, including coal mines, petroleum refineries, and entities required to report natural gas deliveries.22
deliveries.23 
A carbon tax/fee would generate a new revenue stream. The magnitude of the revenues would depend on the scope and rate of the tax or fee, the responsiveness of covered entities in reducing their potential emissions, and multiple other market factors. A 2016 Congressional Budget Office 
study estimated that a $25/ton carbon tax would yield approximately $100 billion bil ion  in the first year 
of the program.23 
24 
When designing a carbon tax/fee system, one of the more controversial and challengingchal enging questions 
for policymakers is how, to whom, and for what purpose the new tax or fee revenues could be applied. Congress would face the same issues that would be encountered during a debate over emission allowance
emission al owance value distribution in a cap-and-trade system. 
  
When deciding how to allocateal ocate the revenues, policymakers would encounter trade-offs among objectives. The central trade-offs involve minimizing economy-wide costs, lessening the costs borne by specific groups—particularly low-income households and displaced workers or 
communities—and supporting a range of specific policy objectives.
A primary argument against a carbon tax/fee system (and a cap-and-trade program) is the concern about the economy-wide costs that a carbon price could impose. The potential costs would depend on a number of factors, including the magnitude, design, and use of revenues of the carbon tax or fee.
 
Others who may oppose a carbon tax system express opposition to federal taxes in general or the possibility that the revenues would enable greater federal spending. Owners of coal resources, in 
particular, would likely   lose asset values under a carbon tax system—as under a cap-and-trade 
system—to the degree that coal becomes less competitive under the costs of emission reductions.

| 1. | GHGs in the atmosphere trap radiation as heat, warming the Earth's surface and oceans. The primary GHGs emitted by human activities (and estimated by EPA in its annual inventories) include CO2, methane, nitrous oxide (N2O), sulfur hexafluoride (SF6), chlorofluorocarbons, hydrofluorocarbons (HFCs), and perfluorocarbons (PFCs). Other GHGs include carbonaceous and sulfuric aerosols, hydrochlorofluorocarbons, and elevated tropospheric ozone pollution generated by emissions of nitrogen oxides and volatile organic compounds, such as solvents. |

| 4. | A number of U.S. states have taken action requiring GHG emission reductions. The most aggressive actions have come from California and from the Regional Greenhouse Gas Initiative (RGGI)—a coalition of nine states from the Northeast and Mid-Atlantic regions. The RGGI is a cap-and-trade system that took effect in 2009 that applies to CO2 emissions from electric power plants. (See CRS Report R41836, The Regional Greenhouse Gas Initiative: Background, Impacts, and Selected Issues, by Jonathan L. Ramseur.) California established a cap-and-trade program that took effect in 2013. California's cap covers multiple GHGs, which account for approximately 85% of California's GHG emissions. For more details, see the California Air Resources Board website, https://www.arb.ca.gov/cc/capandtrade/capandtrade.htm. In addition to its emissions cap, California has adopted a range of other climate change mitigation policies (e.g., renewable energy portfolio standards). |

| 6. | The 1990 Clean Air Act Amendments established a market-based cap-and-trade program to control the air emissions (sulfur dioxide and nitrogen oxides) that lead to acid rain. Although controversial at its inception, the program is widely considered a success.

| 15. | In some instances, legislation would have directed EPA to establish a GHG emissions reduction program with a market-based approach as one option. An alternative approach to a market-based system might involve regulatory directives that require emission performance standards for specific sources or the application of best available control technology. | 
| 16. | A metric ton is approximately 2,205 pounds. A short ton equals 2,000 pounds. | 
| 17. | This term of measure (CO2e) is used because GHGs vary by global warming potential (GWP). GWP is an index developed by the Intergovernmental Panel on Climate Change (IPCC) that allows comparisons of the heat-trapping ability of different gases over a period of time, typically 100 years. Consistent with international GHG reporting requirements, EPA's most recent GHG inventory (2018) uses the GWP values presented in the IPCC's 2007 Fourth Assessment Report. For example, based on these GWP values, a ton of methane is 25 times more potent than a ton of CO2 when averaged over a 100-year time frame. The IPCC has since updated the 100-year GWP estimates, with some increasing and some decreasing. For example, the IPCC 2013 Fifth Assessment Report reported the 100-year GWP for methane as ranging from 28 to 36. EPA compares the 100-year GWP values in Table 1-3 of its 2018 GHG Inventory. | 
| 18. | Both the RGGI and California cap-and-trade systems allow offsets as a compliance option (see footnote 4). | 
| 19. | This differs from a price system that applies to energy content, such as a tax based on British thermal units (Btu). In 1993, President Clinton proposed a deficit reduction package that included a tax based on energy content, measured in Btu. The goals of the 1993 Btu tax proposal were to promote energy conservation and raise revenue. At the time, the proposed tax would have generated a new revenue stream of about $30 billion per year. The proposal was met with strong opposition and was not enacted; Congress ultimately enacted an approximately five-cent-per-gallon increase in the motor fuels taxes. |
