International Governance Of Ocean-Based Carbon Dioxide Removal: Recent Developments And Future Directions, Romany M. Webb

Sabin Center for Climate Change Law

With the impacts of climate change intensifying, and progress in reducing the greenhouse gas emissions that cause it continuing to lag, the parties to the Paris Climate Agreement have emphasized the need to accelerate efforts to remove carbon dioxide from the atmosphere, while simultaneously curbing emissions. As the parties have recognized, the ocean is already a major carbon sink, and could play an important role in future carbon dioxide removal (“CDR”) efforts. Scientists have proposed a variety of ocean-based CDR approaches, but most require further research to fully evaluate their efficacy, benefits, and risks. In-ocean testing of the approaches, and …

Legal Issues In Oceanic Transport Of Carbon Dioxide For Sequestration, Carolina Arlota, Michael B. Gerrard, Pria Deanna Mahadevan

Faculty Scholarship

A number of large facilities intended for the permanent sequestration of carbon dioxide are being developed in the United States. Several of them will be located in Texas and Louisiana on or near the coast of the Gulf of Mexico, making them easily accessible to ships. At the same time, there is substantial interest in Europe in installing equipment to capture carbon dioxide from certain industrial operations before it is emitted into the atmosphere, but currently there are inadequate facilities existing in Europe to sequester much of this carbon dioxide. Therefore, there is interest in the possibility of using ships …

Harmonizing Product-Level Ghg Accounting For Steel And Aluminum, John Biberman, Gyunbae Joe, Perrine Toledano

Columbia Center on Sustainable Investment

Greenhouse gas (GHG) accounting methods for steel and aluminum products have begun converging towards common standards within their respective industries in recent years. However, accounting methods for steel products and aluminum products are still not fully comparable with each other. If emissions are measured and allocated differently for these products, then these accounting differences have the potential to influence materials choices for manufacturers concerned about reducing their reported GHG footprint. Companies could therefore be motivated to make a choice between aluminum and steel according to emissions benefits that materialize from differences in accounting frameworks, but which do not actually exist …

Finance For Zero: Redefining Financial-Sector Action To Achieve Global Climate Goals, Lisa E. Sachs, Nora Mardirossian, Perrine Toledano

Columbia Center on Sustainable Investment

As of 2023, the financial system is woefully misaligned with the world’s climate goals. Six times the current annual level of investment in non-fossil fuel investments is needed between 2023 and 2030 to stay on a 1.5ºC warming pathway. The ratio of clean-energy lending and equity underwriting by banks relative to fossil fuels needs to reach 4 to 1 by 2030, whereas for 1,142 assessed banks, the ratio was between 0.8 and 1 at the end of 2021.

As providers, underwriters, and fiduciaries of trillions of dollars of capital flows annually, financial institutions (FIs) play a critical role in decarbonizing …

Commentary: Nature-Based Insetting: A Harmful Distraction From Corporate Decarbonization, Nora Mardirossian, Jack Arnold

Columbia Center on Sustainable Investment

Carbon offsetting is used worldwide on a massive scale, purportedly to mitigate climate change by capturing atmospheric carbon or by increasing or protecting carbon storage. Yet, in recent years, offsetting has been increasingly criticized as a strategy that can harm Indigenous peoples and local communities, exacerbate land inequality, and, paradoxically, worsen the global climate crisis. “Carbon insetting” has emerged as an alternative approach to offsetting that localizes nature-based solutions projects and other greenhouse gas removal activities within company value chains and has been adopted by major global brands such as Nestlé, PepsiCo, and Burberry. This commentary takes a deep dive …

Ghg Accounting Methods In The Aluminum Industry, John Biberman, Perrine Toledano, Rohini Ram Mohan

Columbia Center on Sustainable Investment

Primary aluminum production is one of the world’s most GHG-intensive industries, and also one where GHG accounting methods have become the most fully developed. GHG reporting for the primary aluminum sector has largely consolidated under the International Aluminium Institute’s (IAI) guidance, although Environment Canada (EC) guidance remains active and Chinese aluminum smelters will soon additionally be required to report their emissions under the China National Development and Reform Commission’s (China NDRC) guidelines, meant to support the development of the Chinese emissions trading system. The IAI method largely follows best GHG accounting practices, but aspects of it can be improved, and …

In California And Europe, A New Dawn For Corporate Climate Disclosure, Magali Delmas, Michael B. Gerrard, Eric Orts

Faculty Scholarship

The Securities and Exchange Commission (SEC) is expected to finalize a new rule this month to cover required corporate climate disclosures by public-reporting companies. But the bigger news is that California Gov. Gavin Newsom (D) has announced that he will soon sign into law two climate change disclosure bills passed by the state Legislature.

Conflicts Between Ghg Accounting Methodologies In The Steel Industry, John Biberman, Perrine Toledano, Baihui Lei, Max Lulavy, Rohini Ram Mohan

Columbia Center on Sustainable Investment

Accurate, verifiable, and comparable greenhouse gas (GHG) emissions data throughout supply chains in the materials sector are necessary to drive decarbonization. This is particularly the case for the steel supply chain, a major source of GHG emissions with untapped potential for reduction. However, emissions accounting methods used by the steel industry suffer from gaps and misalignment, resulting in significant differences in reported GHG emissions. The result is a patchwork reporting landscape vulnerable to manipulation and miscommunication, generating little actionable data for policymakers, producers, customers, and investors. These shortcomings highlight the need for a harmonized carbon accounting framework for the steel …

How Much Have The Oil Supermajors Contributed To Climate Change?, Jiarui Chen, Perrine Toledano, Martin Dietrich Brauch

Columbia Center on Sustainable Investment Staff Publications

In the 40-year period 1980–2019, annual carbon dioxide (CO2) emissions from fossil fuel combustion, including flaring, increased by more than 80%, and total emissions from those sources represented approximately 83% of anthropogenic CO2 emissions (also including cement production and land-use change) without accounting for sinks. Understanding the carbon footprint of countries and companies along the oil value chain is fundamental to outlining paths to reduced reliance on fossil fuels. However, academic analyses of carbon footprints are limited by the lack of a reliable dataset and carbon accounting method that would allow comparisons across countries and companies.

Cooperation Without Convergence: Border Carbon Adjustment And Heterogeneity Of Climate Actions, Lucas Moreira Jiminez

LL.M. Essays & Theses

Border Carbon Adjustment measures (“BCAs”) were originally conceived to help solve a problem that arises when countries ask firms to internalize the costs of environmental depredation in an open economy. Environmental regulation raises costs to domestic producers who feel and are — both are relevant — disadvantaged vis-à-vis their foreign competitors subject to lower regulatory costs, in ways that impact economic competitiveness but also the effectiveness of the regulation itself, to the extent it is directed at a ‘global commons’ problem such as reducing greenhouse gas (“GHG”) emissions in an attempt to mitigate climate change. However, BCAs create issues of …

Looking Out, Looking In: How India Can Respond To A Carbon Border Adjustment Mechanism On The Principles Of Justice And Equity In The Net-Zero Transition, Paridhi Srivastava

LL.M. Essays & Theses

The net-zero transition is a curious term. It is multi-dimensional. It must be inclusive, equitable, and just—considering the different realities of various economies and various pathways to achieving net-zero. One of the merits of global climate action since the Paris Agreement in 2015 has been its attempt to balance climate change justice with inter-generational justice and environmental justice. But as evidenced from the international momentum brewing in a post-Paris world leading up to Glasgow, the problems of justice are not abated with a net-zero transition — they are indeed being rendered more poignant by it. While it is just to …

The Law And Science Of Climate Change Attribution, Michael Burger, Jessica A. Wentz, Radley Horton

Sabin Center for Climate Change Law

There is overwhelming scientific agreement that human activities are changing the global climate system and that these changes are already affecting human and natural systems. Significant advances in climate change detection and attribution science – the branch of science that seeks to isolate the effect of human influence on the climate and related earth systems – have continued to clarify the extent to which anthropogenic climate change causes both slow onset changes and extreme events. The spike in deaths and costs associated with extreme events and the prospect for slow onset changes with irreversible impacts has inspired a marked increase …

Potential Tensions Between New York’S Climate Change Laws And Historic Preservation Laws, Michael B. Gerrard, Edward Mctiernan

Faculty Scholarship

For many years, designated historic buildings have been exempt from most energy conservation codes. However, with increased attention to the perils of climate change, some cities – including New York – are adopting strong laws on building energy use that do not have this exemption. Historic preservation laws that have not caught up, and some fire codes, may pose obstacles to the installation of rooftop solar and some other methods to reduce building energy consumption.

The Law And Science Of Climate Change Attribution, Michael Burger, Jessica A. Wentz, Radley Horton

Sabin Center for Climate Change Law

There is overwhelming scientific agreement that human activities are changing the global climate system and these changes are already affecting human and natural systems. The observational record shows that the planet is getting significantly warmer, with eighteen of the nineteen warmest years on record occurring since 2001. Other observed changes include rising sea levels, ocean warming and acidification, melting sea ice, thawing permafrost, increases in the frequency and severity of extreme events, and a variety of impacts on people, communities, and ecosystems. There are multiple lines of evidence linking these changes to anthropogenic influence on climate.

Legal Tools For Achieving Low Traffic Zones (Ltzs): Lez, Ulez & Congestion Pricing In The U.S. Law Context, Amy E. Turner

Sabin Center for Climate Change Law

Cities around the world are looking to reduce greenhouse gas and other emissions from vehicles through the use of low emission zones and congestion pricing. These strategies have been employed to great success abroad, including in central London, where both congestion pricing and fees and restrictions on higheremitting vehicles are in effect. In the U.S. law context, these policy approaches give rise to significant legal issues that have not been well-explored. This Article proposes that these policy approaches be called “Low Traffic Zones” (LTZs), and surveys those legal considerations. The areas of law explored are: (1) potential for preemption of …

Compilation Of Recommendations To Reduce Greenhouse Gas Emissions In New York State, Kate Marsh, Neely Mckee, Jordan Gerow

Sabin Center for Climate Change Law

The Climate Leadership and Community Protection Act (CLCPA) was passed by both houses of the New York State legislature and signed into law by Governor Andrew Cuomo in June 2019. It took effect on January 1, 2020. It requires total statewide greenhouse gas (GHG) emissions to be 40% below 1990 levels in 2030 and 85% below 1990 levels in 2050, with an aspirational goal of a 100% reduction in 2050. It is one of the strongest climate change laws in the world, and people everywhere are watching its implementation for models of what can be done elsewhere.

The CLCPA establishes …

How Lawyers Can Help Save The Planet, Michael B. Gerrard, John C. Dernbach

Faculty Scholarship

Scientific reports, coming in a steady stream, are highlighting the urgency of reducing greenhouse gas emissions so as to avoid the worst impacts of climate change. Already, hurricanes, coastal and inland flooding, wildfires, heat waves and other extreme weather events are causing severe economic damage and loss of life, and their increasing severity has been attributed to climate change. The decades to come promise to be even worse.

Survey Of Greenhouse Gas Considerations In Federal Environmental Impact Statements And Environmental Assessments For Fossil Fuel-Related Projects, 2017-2018, Madeleine Siegel, Alexander Loznak

Sabin Center for Climate Change Law

Climate change is already generating enormous costs to the environment and public health both in the United States and around the world. These costs will only escalate over the time with increasing greenhouse gas (GHG) emissions. Under the National Environmental Policy Act (NEPA), U.S. federal agencies must assess the environmental effects of proposals for major federal projects, plans and programs before deciding if they should proceed. To conduct a meaningful environmental review of proposed projects, federal agencies must carefully consider how these projects contribute to climate change and greenhouse gas emissions – particularly for projects concerning fossil fuel extraction, transport, …

U.S. Climate Change Litigation In The Age Of Trump: Year Two, Dena P. Adler

Sabin Center for Climate Change Law

More than two and a half years into the Trump Administration, no climate change-related regulatory rollback brought before the courts has yet survived legal challenge. Nevertheless, climate change is one arena where the Trump Administration’s regulatory rollbacks have been both visible and real. The Administration has delayed and initiated the reversal of rules that reduce greenhouse gas (GHG) emissions from stationary and mobile sources; sought to expedite fossil fuel development, including in previously protected areas; delayed or reversed energy efficiency standards; undermined consideration of climate change in environmental review and other decisionmaking; and hindered adaptation to the impacts of climate …

Determining Climate Responsibility: Government Liability For Hurricane Katrina?, Teresa Chan, Michael Burger, Vincent Colatriano, John Echeverria

Sabin Center for Climate Change Law

In St. Bernard Parish Government v. United States, Louisiana property owners argued that the U.S. government was liable under takings law for flood damage to their properties caused by Hurricane Katrina and other hurricanes. The U.S. Court of Appeals for the Federal Circuit disagreed, however, noting that the government cannot be liable on a takings theory for inaction, and that the government action was not shown to have been the cause of the flooding. On September 6, 2018, the Environmental Law Institute hosted an expert panel to explore this ruling and its potential implications for future litigation in a …

Going Negative: The Next Horizon In Climate Engineering Law, Tracy Hester, Michael B. Gerrard

Faculty Scholarship

As the global community struggles to turn the Paris Agreement’s commitments into meaningful emission reductions and the United States turbulently reverses its climate policies, the potential role of “negative emissions technologies” and other climate engineering approaches is drawing increasingly serious attention. These technologies are engineering on the grandest scale: climate engineering seeks to offset the effects of anthropogenic climate change by either altering the solar radiation reaching the earth’s surface or changing the composition of the atmosphere itself. Specifically, negative emissions technologies would directly remove greenhouse gases (GHGs) from the ambient air and help to remove accumulated atmospheric carbon dioxide …

The Legal Basis For Imo Climate Measures, Aoife O'Leary, Jennifer Brown

Sabin Center for Climate Change Law

This paper investigates the potential legal bases for the International Maritime Organization (IMO) to enact climate measures. It finds that the IMO has broad powers to enact almost any required measure, and quickly via a tacit amendment to the International Convention for the Prevention of Pollution from Ships (MARPOL).

Climate Change And Human Trafficking After The Paris Agreement, Michael Gerrard

Faculty Scholarship

At least 21 million people globally are victims of human trafficking, typically involving either sexual exploitation or forced labor. This form of modern-day slavery tends to increase after natural disasters or conflicts where large numbers of people are displaced from their homes and become highly vulnerable. In the decades to come, climate change will very likely lead to a large increase in the number of people who are displaced and thus vulnerable to trafficking. The Paris Climate Agreement of 2015 established objectives to limit global temperature increases, but the voluntary pledges made by nearly every country fall far short of …

Sequestering Carbon Dioxide Undersea In The Atlantic: Legal Problems And Solutions, Michael B. Gerrard, Romany M. Webb

Faculty Scholarship

Reducing the amount of carbon dioxide in the atmosphere is vital to mitigate climate change. To date, reduction efforts have primarily focused on minimizing the production of carbon dioxide during electricity generation, transport, and other activities. Going forward, to the extent that carbon dioxide continues to be produced, it will need to be captured before release. The captured carbon dioxide can then be utilized in some fashion or injected into underground geological formations (e.g., depleted oil and gas reserves, deep saline aquifers, or basalt rock reservoirs) where it will hopefully remain permanently sequestered. This injection process is referred to as …

Act Locally, Reflect Globally: A Checklist Of Options For U.S. Cities And States To Engage Internationally In Climate Action, Susan Biniaz

Sabin Center for Climate Change Law

U.S. cities and states are increasingly asking how they can play a more visible and active role in international climate change efforts.

Cities and states have obvious incentives to take action to mitigate and adapt to climate change. But why engage internationally? They may seek to demonstrate leadership or gain appropriate recognition for “doing their part.” They may want to inspire others to follow suit or support them in doing so, such as through exchanging best practices. They may seek to join the global march toward low-emission and resilient societies. Or they may want to show the world that U.S. …

To Negotiate A Carbon Tax: A Rough Map Of Policy Interactions, Tradeoffs, And Risks, Justin Gundlach

Sabin Center for Climate Change Law

Sooner or later, the federal government will assign a price to carbon dioxide emissions via legislation. The contents of that legislation will reflect negotiated agreement – built on various political tradeoffs – over a host of policy issues, ranging from taxes to energy efficiency standards. These tradeoffs would implicate not only the scope and price assigned by the carbon pricing policy, but also the policies with which it would interact. This paper anticipates that price will take the form of a carbon tax and describes interactions between that tax and various existing and proposed policies relating to climate change, energy, …

The Energy Improvement Of The Urban Existing Building Stock: A Proposal For Action Arising From Best Practice Examples, Teresa Parejo-Navajas

Sabin Center for Climate Change Law

Improving energy efficiency in existing buildings presents an opportunity for reducing greenhouse gas emissions. Numerous measures meant to increase efficiency and decrease emissions have been implemented in cities across Europe and the United States. Standing out from the rest is New York City, a remarkable example of commitment to the fight against climate change. The city has urged its authorities to take important measures in order to eliminate (or at least diminish) the adverse effects resulting from its special characteristics, great urban density, and large percentage of greenhouse gas emissions coming from an aged building stock. Yet there is always …
