I. Energy Transition Leadership

As wildfires rage across the western United States and the Gulf Coast bears the impact of increasingly devastating hurricanes, it is evident that climate change is affecting the daily lives of many across the country and the world.[1] Many attribute these effects to the environmental impact of fossil fuels.[2] Consequently, there is a concerted effort to decarbonize society and execute a global energy transition.[3] A transition of this magnitude cannot be performed on a dime, especially with global energy demand projected to increase, surpassing the capabilities of the current renewable infrastructure.[4] Nonetheless, a more efficient transition is possible if International Oil Companies (IOCs) lead the charge. However, their ability to do so requires adjustments to the current legal framework.

IOCs’ business models and current infrastructure support large-scale projects, and their existing operations rank them among the largest greenhouse gas emitters, putting them in a unique position to lead the global transition to a lower carbon landscape.[5] However, IOCs face major obstacles in leading this transition, some of which can be mitigated by implementing legal solutions in the form of prescriptive regulations on carbon-emitting operations, regulations intended to influence market behavior, and removing regulations that serve as legal barriers to transition. Because the United States is one of the only Western nations lacking formal emissions regulations, this Comment will analyze existing international laws and policies and propose solutions directed towards domestic implementation.[6] Part II will lay the foundation and give a summary of IOCs’ current business models, discuss the pressure they face to transition to low-carbon energy, and address the gap between forecasted total energy demand and renewable energy production targets. Part III will identify the current laws and regulations, or lack thereof, on international, domestic, and local levels. Part IV will return to facilitating the IOCs’ leadership in the transition and discuss legal solutions that enable IOCs to be major contributors in achieving emissions reductions goals. Finally, Part V will propose the best solution(s), highlight key implementation strategies in the United States, and briefly examine the global impact.

II. IOCs’ Infrastructure and Incentives Enable Change

IOCs, as compared to their petroleum industry counterparts, are publicly owned and globally operated companies that typically operate in all stages of the hydrocarbon extraction supply chain.[7] Often thought of as the “super majors,” ExxonMobil, Shell, TOTAL, BP, and Chevron are the most familiar IOCs.[8] These companies solidified their status atop the oil industry in the 1990s and early 2000s, when a decline in oil prices incentivized mergers of already sizeable entities into adequately named “big oil” corporations.[9] A key characteristic of super majors and many IOCs is their business’s integration from oil and gas exploration, production, transportation, storage, marketing, refining, all the way to the final sale of products.[10]

IOCs play a pivotal role in meeting global energy demand through fossil fuels, but the shift towards renewable energy poses new obstacles for the sector.[11] Governments and corporations are setting carbon emission reduction goals as the global energy demand is expected to increase, leaving a gap in energy demand that cannot be met with today’s renewable technologies.[12] IOCs must continue investing in low-carbon technologies to ensure their long-term profitability, while maintaining conventional energy production to fill the gap.[13] Investment strategies include integrating low-carbon technologies into fossil fuel production, expanding beyond traditional fossil fuel production, and aiming to lower emissions in existing operations.[14]

The shift in energy demand from fossil fuels to low-carbon or no-carbon energy requires IOCs to adapt in order to survive. Fortunately, IOCs possess nonindustry-specific characteristics that lend themselves to renewable energy development and overall carbon emission reduction. By nature of their presence across the petroleum product value chain on an international level, IOCs have a robust asset portfolio that is highly technical at every stage.[15] The expertise and budget used in developing and growing such a portfolio are transferable to growth and development in the low-carbon space.[16] These characteristics, as well as the physical assets themselves, translate well into renewable energy development.[17] For example, low-carbon energy ventures, like offshore wind energy, leverage IOCs’ existing oil- and gas‑producing platforms in various coastal and deep-water locations, as well as their proficiency in building offshore infrastructure.[18] Also, IOCs are already using their existing networks of service stations to house charging stations for electric vehicles.[19]

Additionally, IOCs must make some efforts to decrease overall carbon emissions in order to survive pressures from governments, investors, and the public.[20] Governmental pressure looks different for each company depending on the regulations in effect in the country in which they are headquartered.[21] The extent to which IOCs experience governmental pressure is also affected by a country’s business–government relationship. The American business–government relationship is such that American oil companies lobby and challenge regulations; whereas, in European nations, a similar approach may be considered too adversarial and negatively impact a company’s credibility.[22]

The oil and gas industry is beginning to report environmental, social, and governance (ESG) metrics. ESG metrics are used to evaluate a company’s operations and performance and ultimately dictate investment decisions and even access to capital.[23] ESG‑focused investors use different strategies to create more sustainable funds and, in turn, affect oil and gas companies to a varying degree.[24] Investors engaging in “negative screening” actively divest any fossil-fuel-focused companies.[25] “ESG integration” funds do not explicitly divest of oil- and gas-based investments but seek to include companies with the best ESG metrics, which often has the same result.[26] These ESG investing strategies caused the energy sector of the U.S. S&P 500 to decrease by 48% from 2015 to 2020.[27]

ESG pressures from the public are apparent in hiring trends. Young professionals are showing skepticism towards oil and gas careers due to climate change concerns.[28] In addition to the oil industry’s struggle to attract and retain talented personnel, “there is [a] growing realization that any company that fails to appreciate the changes induced by climate change concerns and societies’ desire for cleaner energy could lose its societal license to operate.”[29] IOCs are facing lawsuits for climate-related problems, further incentivizing, or perhaps necessitating, a change.[30] Despite their roles as the predominant carbon emission culprits,[31] IOCs’ current position in the energy sector, corporate characteristics, infrastructure, and renewable investments to date make them likely candidates to lead a successful effort toward global emissions reduction.

III. Current Regulatory Landscape Leaves Room for Federal Action

Because climate change poses a global threat, countries are taking varied approaches, jointly and independently, to address the dilemma.[32] Part III analyzes regulations, ranging from international agreements to local laws, to understand the current international regulatory landscape as a basis for potential federal solutions in the United States.

A. International Agreements Lack Enforceable Obligations

At the international level, the United Nations Framework Convention on Climate Change (UNFCCC) is a legal regime that puts the responsibility on countries to reduce greenhouse gas emissions within their jurisdictions.[33] Dating back to 1992, the UNFCCC facilitates treaties and other international laws that are often referred to in the aggregate as the “UN climate regime.”[34] The UNFCCC’s objective is the “stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system.”[35] The UNFCCC itself lacks firm emissions reduction targets and does not provide any recourse for parties that do not comply to its vague provisions, but it paved the way for subsequent international agreements with more definite commitments.[36] Specifically, Article 7 of the UNFCCC establishes the “Conference of the Parties” and ensures the parties will regularly meet to make decisions that further the efforts articulated at the convention.[37] Additionally, the UNFCCC first expressed the concept of “common but differentiated responsibilities and respective capabilities” by dividing parties into categories of “developed” and “developing” countries and tasked developed countries with leading the climate change efforts by “recogni[zing] . . . the specific needs and special circumstances of developing countries.”[38] The “common but differentiated responsibilities and respective capabilities” remains a theme throughout the U.N. climate regime.[39]

The Kyoto Protocol, adopted at the third Conference of the Parties, sets forth a target for developed countries—to reduce greenhouse gas emissions by 5% compared to their 1990 emissions levels during a commitment period of 2008 to 2012.[40] To achieve this target, Article 2 encourages each country to implement specific policies and measures.[41] Notably, the Article encourages “[p]rogressive reduction or phasing out of market imperfections, fiscal incentives, tax and duty exemptions and subsidies in all greenhouse gas emitting sectors that run counter to the objective of the Convention.”[42] Specific to the energy sector, the Kyoto Protocol tasks parties with formulating national and regional programs to mitigate climate change from certain sectors, including energy, transportation, and industry.[43] Although developing countries are not subject to emissions-reductions targets under the Kyoto Protocol, their commitments under the UNFCCC remain intact.[44] The Doha Amendment to the Kyoto Protocol, effective December 30, 2020, creates a second commitment period calling for an 18% reduction in emissions compared to 1990 levels between 2013 and 2020.[45]

The Paris Agreement, a product of the 2015 Conference of Parties, expands the reach of international climate change regulation by including commitments from developing nations.[46] Among the key commitments in the Paris Agreement is the effort to limit the global average temperature increase to 1.5 degrees Celsius above preindustrial levels.[47] Although prior drafts of the Paris Agreement included specific language about reducing dependency on fossil fuels, only a vague mention of striving for a “balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases in the second half of this century” is in the final document.[48] Also relevant to the energy sector, the Paris Agreement does not include a carbon tax as requested by some IOCs, but it mentions carbon pricing as an important tool to incentivize emission reduction activities.[49]

Conferences following the Paris Agreement continue to disappoint those seeking to elicit lofty commitments from some of the world’s largest emitters.[50] Under President Trump’s Administration, the United States formally withdrew from the Paris Agreement effective November 4, 2020,[51] but rejoined January 20, 2021, on President Biden’s first day in office.[52] The Paris Agreement, the UNFCCC, and international climate change regulations as a whole will only be as successful as the parties’ efforts in their own countries, which are highly scrutinized.[53] Countries’ commitments to the Paris Agreement and other UNFCCC decrees do not include any mandates involving IOCs in particular; however, the indirect effects of ESG motivations in reaction to the Paris Agreement are evident.[54]

B. National Climate Change Policies in Developed Countries Vary Drastically

It is important to understand the dynamic between countries and the energy sector through international climate change laws and policies, but laws and regulations enacted on the national and local levels are most likely to impact IOCs and their ability to efficiently transition to a lower carbon environment. National policies vary drastically from country to country. For example, the United States lacks climate-change-related regulations at the federal level.[55]

The European Union, on the other hand, set forth a net zero emissions policy for 2050 but has yet to enforce any industry-level regulations affecting specific actors.[56] Although the EU’s efforts to formalize ESG standards do not directly regulate emissions, they could certainly have the same effect.[57] Much of the EU’s emissions reduction thus far is attributable to its Emissions Trading System.[58] Emissions trading systems are evaluated in depth in Part IV of this Comment, but it is relevant to note the EU’s success with this mechanism thus far.

Responsible for almost one fourth of global greenhouse gas emissions, China also has a goal to be carbon neutral by 2060.[59] China currently relies on coal for residential and commercial heating, and its efforts to transition to natural gas will likely assist in the country’s quest for carbon neutrality.[60] Additionally, China is home to the China National Petroleum Corporation (CNPC), a National Oil Company (NOC) and the country’s largest oil and gas producer.[61] CNPC mirrored China’s ambitious emissions reduction goal with a pledge of its own—to cut methane emissions 50% by 2025.[62] As CNPC’s largest investor and shareholder, China has a good chance of achieving its aggressive targets by directing CNPC to lower carbon operations through its ownership relationship.[63]

C. Local Climate Change Regulations Alone Are Not Sustainable

Although the U.S. government was mostly silent on the climate problem until President Biden’s Executive Orders and Memorandum addressing climate change in January 2021,[64] state governments continue to address the issue through various forms of legislation.[65] Some states set emissions reduction targets but did not include formal communication about how to achieve those targets.[66] States’ actions thus far target individual sectors such as electricity, transportation, real estate, industry, and agriculture, and even utilize green banks and implement clean energy funds to finance renewable energy projects.[67] For example, New York passed a policy requiring carbon-free electricity by 2040.[68] The State of Washington targeted commercial real estate by enacting the Clean Buildings Act, which requires new and existing buildings to comply with heightened energy efficiency standards.[69] States often operate as “laboratories of democracy” for potential federal regulation, and climate change is no exception.[70] However, regulating exclusively at the local level is not sustainable. With a growing number of states calling for low-carbon buildings and clean transportation, the renewable energy supply will not be able to keep up with the increased demand, and a federal solution taking IOCs’ needs into account is necessary to achieve states’ goals.[71]

IOCs’ obstacles in transitioning to low-carbon operations center on continuing to meet the physical fossil fuel demand and capital constraints in both the ability to make an initial investment in low-carbon operations and the willingness to accept a lower rate of return than those expected with upstream fossil fuel investments.[72] These obstacles are not insurmountable—there are legal solutions to overcome challenges in meeting physical energy demand, overcoming capital constraints, and other concerns associated with IOCs’ transitions. These legal solutions come in various forms and can be implemented at the local, federal, and international levels. Part IV specifically addresses solutions the United States can implement at the federal level through prescriptive regulations, market-based legal solutions, and removing existing regulations.

A. Combination of Prescriptive Regulations Balance Environmental and Financial Concerns

Likely the most publicly recognized form of regulation, prescriptive regulations are often direct limits, prohibitions, or other requirements on emissions levels.[73] In Massachusetts v. EPA, the Supreme Court recognized greenhouse gases as air pollutants and thus regulatable under the Clean Air Act.[74] Accordingly, the federal government has the authority to enact prescriptive regulations, or “command-and-control regulations,” addressing energy distribution through environmental and energy law instruments.[75] For example, the federal government can introduce emissions limits on fossil fuel industry operations directly or on the industry’s consumers, affecting fossil fuel industry players through the resulting change in demand.[76] Additionally, the federal government can prohibit the use of greenhouse-gas-intensive materials altogether.[77] Ancillary requirements placed on current fossil fuel operations may also serve as effective prescriptive regulations.

As discussed in Part III, IOCs already face prescriptive regulations on their operations in other developed countries.[78] Implementing similar regulations in the United States is not only feasible, but could provide the predictability and equal opportunity environment required for industry players to transition to lower carbon operations.[79] Setting forth specific emission limits on fossil fuel operations incentivizes IOCs to leverage their research and development expertise in adapting to regulations immediately as opposed to waiting until they are forced to make such efforts in reaction to competitor innovations or investor prudence. Continued technological development in current fossil fuel operations has the ability to address both hurdles IOCs must overcome—the physical energy demand and capital constraints—but not without additional regulatory assistance. Long term, innovation ideally allows IOCs to streamline operations and cut costs, but there is still the upfront expense required to invest in any new venture that even explicit limits on emissions cannot justify.[80]

Prescriptive regulations in the form of carbon capture, utilization, and storage (CCUS) requirements may be an effective way to limit emissions in the near term but may also perpetuate fossil fuel usage.[81] CCUS is the capture and storage of the carbon dioxide normally emitted during industrial processing to prevent emitting it into the atmosphere and potentially use it in other industrial processes.[82] Forced, or at least incentivized, CCUS enacted at the federal level can help achieve decarbonization goals without abruptly eliminating fossil fuel availability.[83] Continuing fossil fuel operations, to some extent, is required for IOCs to meet near-term energy demand, one of the main obstacles they face in the energy transition.[84] When it comes to capital concerns, CCUS requires an upfront capital investment, but the ability to utilize or sell the gas that is captured may boost project economics enough to realize a significant return.[85] Further regulatory intervention can also help alleviate capital concerns. For example, the federal government can direct agencies to purchase energy produced using CCUS or provide tax credits to those participating in carbon sequestration.[86] If they are not already using CCUS operations, IOCs are well-positioned to implement the technology and even advance current abilities using their large research and development budgets along with their expertise in large-scale infrastructure.[87]

A more extreme prescriptive regulation is a blanket prohibition. While a blanket prohibition on heavy‑greenhouse‑gas‑emitting materials, such as plastics, would undoubtedly lower emissions, this solution reaches beyond what is necessary to achieve a more seamless transition with IOCs at the helm.[88] However, production of plastics and other products with large carbon footprints could decrease as a byproduct of direct regulation on emissions.[89]

One type of prescriptive regulation alone may not be the key to overcoming IOCs’ obstacles in transitioning to low-carbon energy solutions. A combination of regulations implemented by the federal government is likely a step in the right direction. Carbon dioxide emissions restrictions and CCUS requirements go hand in hand.[90] Emissions restrictions force IOCs to implement CCUS technologies to keep existing fossil fuel operations in compliance before renewable energy solutions are capable of meeting the demand.[91] Regulations that incentivize CCUS provide the necessary financial assurances for IOCs to overcome the upfront implementation cost and ideally free up any additional capital to fund further investment in renewable, or no-carbon, technologies.[92] With the right combination, federal prescriptive regulations can assist IOCs in leading the transition to cleaner energy while maintaining the adequate fossil fuel supply to meet near-term energy demand.

In addition to prescriptive regulations, market-based legal solutions implemented at the federal level can assist IOCs in their low-carbon pursuits and allow them to be industry leaders in the energy transition. Market-based legal solutions are “a mode of governance that intends to affect market behavior by using prices, incentives, and other market signals within already-existing markets.”[93] These legal tools are broadly categorized into positive incentives that make it financially beneficial to engage in the desired behavior and negative incentives that make disfavored actions more expensive.[94]

Positive incentives include issuing green bonds—bonds in which the issuance proceeds are used to finance carbon emissions mitigation projects.[95] Green bonds can be government-issued or company-issued by some of the world’s largest emitters.[96] Although there is some opposition to green bonds, they play a key role in financing clean energy projects and provide tax incentives to make IOCs’ large-scale investments feasible.[97] Tax credits are another important legal tool in incentivizing renewable investments.[98]

Negative incentives include pollution charges, taxes, and fees.[99] A carbon tax is a logical place to start in terms of penalizing environmentally harmful behavior.[100] Carbon taxes increase the price of fossil fuels and its derivative products by charging a fee based on the carbon content.[101] Carbon taxes not only disincentivize high-carbon operations and promote investment in low-carbon technologies but also have the potential to raise a significant amount of capital that can be used to further decarbonization efforts.[102] The scalability of a carbon tax makes its implementation in the United States at the federal level feasible.[103] However, a federal carbon tax requires tax adjustments on imported goods to ensure international trade does not circumvent the tax entirely.[104] Although there are other market‑leveraging negative incentives available, a carbon tax is the most logical place to start.[105]

Both positive and negative market-leveraging incentives implemented at the federal level have the potential to assist IOCs in leading the energy transition. Positive incentives in the form of green bonds or tax credits assist IOCs in overcoming the capital constraints of renewable investments. Green bonds, specifically, can assist IOCs in raising the required initial capital investment.[106] Additionally, factoring tax credits into project financing increases the rate of return on renewable projects, making a smoother transition from IOCs’ typical high-return fossil fuel projects.[107] Making renewable and low-carbon project investments more feasible allows IOCs to continue meeting the physical demand for fossil fuels throughout the transition without forfeiting all their resources to new projects.[108] Negative incentives, specifically carbon taxes, are undoubtedly effective in reducing emissions, and even large oil companies have indicated their support for a carbon tax plan.[109] However, a carbon tax plan is likely to be only as effective as the other measures that accompany the plan.[110] Without accompanying regulations, a blanket carbon tax increases the cost of IOCs’ fossil fuel operations, which will likely just be passed on to the consumer.[111] Neither of IOCs’ primary obstacles—meeting physical energy demand or addressing IOCs’ capital constraints—are addressed through carbon taxation alone.

C. Removing Regulations May Be More Effective than New Regulations

Regulations that either incentivize fossil fuel use or serve as a barrier to entry into the renewable space deserve just as much, if not more, attention in the decarbonization conversation than creating new regulations. Like the proposed tax incentives for renewable investments discussed as a positive market-based legal solution, there are laws that currently subsidize, or incentivize, fossil fuel use and development.[112] Originally put in place to encourage domestic energy production, fossil fuel subsidies in the United States remain in effect despite being seemingly at odds with current energy policy.[113] For example, companies are allowed to deduct a majority of the costs associated with drilling new oil and gas wells,[114] account for declining hydrocarbon reserves to decrease taxable income,[115] as well as take advantage of various incentives that indirectly subsidize the fossil fuel sector.[116] Eliminating, or at least limiting, the current subsidies in the United States is an “obvious decarbonization tool,” and congressional reform efforts are ongoing.[117]

In addition to promoting fossil fuel use, current regulations can act as barriers to investing in renewable or alternative energy sources.[118] Most applicable to IOCs are regulations that govern the permitting and licensing processes of energy sources.[119] The permitting and licensing phase is often the most time-consuming and expensive portion of a project lifecycle, and relieving renewable energy investors of excessive requirements would make advancing toward the decarbonization goal much easier.[120] Because renewable energy is a relatively young industry and technology is constantly evolving, a “streamlined” patent process for new technologies would also remove unnecessary barriers to decarbonization.[121]

IOCs’ obstacles in leading the energy transition can be mitigated by removing both pro-fossil fuel subsidies and burdensome alternative energy regulation. While removing fossil fuel subsidies makes IOCs’ hydrocarbon operations and future projects more expensive, IOCs are large enough and represent enough of the value chain to accommodate such circumstances.[122] In fact, removal of subsidies on undeveloped resources will narrow the field of profitable investments, freeing capital to invest in alternative energy methods.[123] Removing fossil fuel subsidies does not directly affect the upfront capital constraint or the “profitability gap” in renewable energy investment, but eliminating regulations that prolong the permitting or patent process for alternative technologies does.[124] A regulatory framework that reduces the time and cost to permit large-scale projects allows IOCs to justify the upfront capital investment and makes alternative energy projects more competitive with fossil fuel projects.[125] Overall, removing regulations that either incentivize fossil fuel investment or burden alternative energy projects is just as effective of a legal tool as additional regulation and should be thoughtfully considered.

V. Conclusion

The United Nations not only describes climate change as the “defining issue of our time” but also states that we are at “the defining moment.”[126] The imminent threats posed by climate change make the transition to low-carbon energy sources of utmost importance.[127] Fortunately, the U.S. government has legal tools at its disposal to enable IOCs, which are uniquely situated in both the fossil fuel and renewable sector, to lead the transition to cleaner energy.[128] Prescriptive regulations, market-based solutions, and removing current regulations can assist in diminishing the obstacles IOCs face in making the transition to cleaner energy.

Because various legal solutions have different effects on the fossil fuel industry, IOCs, and society, it is important to consider combining approaches to achieve the desired results. Although both approaches require congressional action, a market-based carbon tax paired with prescriptive CCUS incentives should be top priority because this combination allows IOCs to continue hydrocarbon operations to meet energy demands in the near term and gradually phase out such operations to meet emissions goals.[129] Direct limitations on emissions can also be effective, but a carbon tax provides more incentive to reduce emissions as much as possible instead of enough to comply with an arbitrary limit.[130] Furthermore, market-based approaches are more flexible in terms of the emitter’s compliance.[131] Flexibility is key as IOCs’ business models evolve to include clean energy.

Carbon taxation paired with CCUS incentives takes direct aim at reducing emissions in the short-term, but long-term goals are not attainable without repealing or restructuring regulations that inhibit low-carbon investment. Streamlining the permitting process is one way to address this issue.[132] Removing these legal barriers puts clean energy projects closer to a level playing field with fossil fuel projects when IOCs evaluate future investments. The federal government’s best approach towards decarbonization with IOCs at the helm starts with a carbon tax, a CCUS regulation, and a streamlined permitting process for clean energy technology and infrastructure.

Congress has been reluctant to pass significant climate change legislation, but the current political landscape and the urgency required to facilitate the energy transition makes now a better time than ever to implement the above-described legal solutions.[133] In addition to formally participating in the global effort to reduce greenhouse gas emissions through the Paris Agreement, implementing legal solutions in the United States will have a global impact.[134] The United States will not only contribute to the global effort by reducing local emissions but also set a policy example encouraging renewable development worldwide.[135] Implementing legal solutions at the federal level that prioritize IOCs’ leadership in the energy transition is key in reaching global climate change goals.
