Implementing The Inflation Reduction Act: Progress To Date And Risks From A Changing Administration, Romany M. Webb, Martin Lockman, Emma Shumway

Sabin Center for Climate Change Law

The Inflation Reduction Act of 2022 (“IRA”) is the largest investment in climate change mitigation and adaptation in American history. The IRA appropriates more than $142 billion to carry out activities designed to reduce greenhouse gas emissions and protect against the impacts of climate change. This includes up to $37 billion in appropriations for federal loans and loan guarantees, and nearly $105 billion allocated for grants, awards, and other direct spending by federal agencies. In addition, the IRA creates and expands a number of tax credit programs designed to support a broad range of climate-related activities, including investments in clean …

Removing Methane Via Atmospheric Oxidation Enhancement: The Legal Framework, Romany M. Webb, Martin Lockman, Korey Silverman-Roati

Sabin Center for Climate Change Law

To achieve the Paris Agreement’s goal of limiting the increase in global average temperatures to “well below 2 degrees Celsius,” and ideally 1.5 degrees Celsius, above pre-industrial levels, global greenhouse gas (“GHG”) emissions must reach net zero in the second half of the century. The global community is not currently on track to achieve net zero emissions. In fact, with the exception of a slight dip during the Covid-19 pandemic, emissions have risen steadily in recent years. This, together with the increasingly visible impacts of climate change, has prompted growing interest in the possibility of removing GHGs directly from the …

The report utilizes data from the Sabin Center’s Global Climate Change Litigation databases, which has seen an influx …

Shocking Financed Emissions: The Effect Of Economic Volatility On The Portfolio Footprinting Of Financial Institutions, Ilmi Granoff, Tonya Lee

Sabin Center for Climate Change Law

Many financial institutions are now calculating and disclosing their financed emissions, a class of metrics enabling these institutions to calculate the greenhouse gas (GHG) emissions associated with investment and lending activities. These institutions have widely adopted the metric to estimate exposure to climate-related financial risk associated with GHG-emitting activities and to provide shareholders and investors a picture of how their financial activity impacts global climate change. Financed emissions metrics, despite widespread adoption, face two key methodological challenges: lack of comparability of outputs within and between portfolios, and vulnerability of calculations to portfolio volatility. Markets are naturally volatile, but the economic …

The Private Litigation Impact Of New York’S Green Amendment, Evan Bianchi, Sean Di Luccio, Martin Lockman, Vincent Nolette

Sabin Center for Climate Change Law

The increasing urgency of climate change, combined with federal environmental inaction under the Trump Administration, inspired a wave of environmental action at the state and local level. Building on the environmental movement of the 1970s, activists have pushed to amend more than a dozen state constitutions to include “green amendments” — self-executing individual rights to a clean environment. In 2022, New York activists succeeded, and New York’s Green Amendment (the NYGA) now provides that “Each person shall have a right to clean air and water, and a healthful environment.”

However, the power of the NYGA and similar green amendments turns …

Executive Actions To Ensure Safe And Responsible Ocean Carbon Dioxide Removal Research In The United States, Romany M. Webb, Korey Silverman-Roati

Sabin Center for Climate Change Law

This paper presents recommended actions that federal agencies could take, under existing law, to ensure safe and responsible permitting and regulation of ocean carbon dioxide removal (CDR) research in U.S. waters. Controlled field trials and other in-ocean research is critical to improve scientific and societal understanding of ocean CDR techniques that could help the U.S. reach its climate goals. That could raise a host of legal issues, however. Existing legal frameworks were not designed to regulate ocean CDR, and federal agencies have yet to fully explain how decades-old environmental laws will be applied to a new set of activities. This …

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 …

This report provides a summary of the briefs and statements submitted to the International Tribunal for the Law of the Sea (ITLOS) in response to the Co-Chairs of Commission of Small Island States (COSIS)’ request for an advisory opinion on climate change-related legal questions. The central issue before the ITLOS is whether State Parties to UNCLOS have specific obligations regarding the prevention, reduction, and control of marine environmental pollution stemming from climate change, as well as the protection and preservation of the marine environment concerning climate change impacts. While States and civil society organizations have put forward a variety of …

Permitting Co2 Pipelines, Martin Lockman

Sabin Center for Climate Change Law

Both emissions reductions and removal of greenhouse gases like carbon dioxide (CO2) from the atmosphere are essential if we hope to minimize the damage caused by climate change and globally reduce our net emissions of greenhouse gasses to zero. Some CO2 removal techniques, like “direct air capture” that uses chemical and electrochemical processes to capture atmospheric CO2 at relatively low concentrations, generate a stream of captured CO2 that is then injected into underground rock formations referred to as “geologic storage.” CO2 pipelines represent the most efficient way to transport high volumes of captured CO2 to geologic storage locations. However, while …

Decommissioning Liability At The End Of Offshore Oil And Gas: A Review Of International Obligations, National Laws, And Contractual Approaches In Ten Jurisdictions, Martin Lockman, Martin Dietrich Brauch, Esteban F. Fresno Rodríguez, José Luis Gallardo Torres

Sabin Center for Climate Change Law

Offshore oil and gas infrastructure faces an existential threat: the increasingly pressing need to address the climate emergency. The Intergovernmental Panel on Climate Change projects that GHG emissions from existing and planned fossil fuel infrastructure will push global warming past the Paris Agreement’s 1.5°C threshold, and more detailed projections estimate that “nearly 60 per cent of oil and fossil methane gas ... must remain unextracted to keep within a 1.5 °C carbon budget.” The growing urgency of climate action, coupled with the increasing adoption of renewable energy systems and energy-efficient technologies, may strand thousands of offshore oil and gas installations …

Beyond The North–South Divide: Litigation's Role In Resolving Climate Change Loss And Damage Claims, Maria Antonia Tigre, Margaretha Wewerinke-Singh

Sabin Center for Climate Change Law

Within the international climate regime, legal aspects surrounding loss and damage (L&D) are contentious topics, implicating liability, compensation and notions of vulnerability. The attribution of responsibility and the pursuit of redress for L&D present intricate legal and governance challenges. The ongoing debates under the United Nations Framework Convention on Climate Change are characterized by a pronounced North–South divide and have done little to provide tangible support to those most affected by L&D. This apparent neglect has prompted exploration of alternative avenues for climate harm redress. The burgeoning field of litigation for liability and compensation of climate harm holds potential significance …

Modelling Climate Litigation Risk For (Re)Insurers, Martin Lockman

Sabin Center for Climate Change Law

In response to the growing threat of climate change, the insurance industry has made significant investments in modelling and quantifying physical climate risks. However, the emerging risk of climate litigation has proven particularly difficult to model. In 2015 Mark Carney, then-Governor of the Bank of England and Chairman of the Financial Stability Board, warned that climate litigation poses “long-tail risks” for insurers that may be “significant, uncertain and non-linear.” Since that warning, the number of climate-related cases has more than doubled, and the scope and financial significance of climate litigation has become increasingly clear. However, insurers and regulators still struggle …

Developing Model Federal Legislation To Advance Safe And Responsible Ocean Carbon Dioxide Removal Research In The United States, Romany M. Webb, Korey Silverman-Roati

Sabin Center for Climate Change Law

This model federal legislation aims to advance safe and responsible ocean carbon dioxide removal (CDR) research in U.S. waters. Controlled field trials and other in-ocean research is critical to improve scientific and societal understanding of CDR techniques that could help the U.S. reach its climate goals. However, existing legal frameworks were not designed to regulate ocean CDR and, in some cases, unnecessarily or inappropriately restrict needed research. The purpose of this proposed model legislation is to establish clear and efficient permitting regime for in-ocean CDR research. At the same time, the model legislation builds in consultation, monitoring, and other safeguards …

Human Rights And Climate Change For Climate Litigation In Brazil And Beyond: An Analysis Of The Climate Fund Decision, Maria Antonia Tigre, Joana Setzer

Sabin Center for Climate Change Law

In 2022, the Brazilian Supreme Court announced a groundbreaking decision in the Climate Fund case. The decision, rendered amidst a challenging political climate, acknowledges the significance of the Paris Agreement within the country’s legal framework. The Court’s ruling established that the executive branch has a constitutional obligation to allocate funds from the Climate Fund for climate change mitigation and adaptation, grounded in the constitutional right to a healthy environment, international rights and commitments, and the principle of separation of powers.

Notably, the Court recognized the Paris Agreement as a human rights treaty, granting it “supranational” status. The implications of the …

Climate Change And Indigenous Groups: The Rise Of Indigenous Voices In Climate Litigation, Maria Antonia Tigre

Sabin Center for Climate Change Law

Climate change’s pervasive human rights impacts on populations worldwide are widespread and now widely known. One avenue to address these human rights impacts is the growth of rights-based climate litigation. There are now hundreds of cases worldwide grounded on human rights claims. However, less attention has been brought to how vulnerable groups are disproportionally affected by climate change. Indigenous groups, in particular, are disproportionately affected by climate change due to their connection to their land and dependence on their ecosystems. To increase global attention and seek legal remedies to address how Indigenous communities are impacted by climate change, Indigenous groups …

Incorporating Climate Change In Nepa Reviews: Recommendations For Reform, Michael Burger, Romany M. Webb, Jessica A. Wentz

Sabin Center for Climate Change Law

The National Environmental Policy Act (“NEPA”) requires federal agencies to conduct an environmental review prior to moving ahead with any major federal project, plan, or program that could significantly affect the environment. As part of the environmental review, agencies must share information with, and solicit feedback from, the public. The goal is to improve federal decision-making by ensuring that agencies take a hard look at the environmental effects of their actions and fully inform the public about those effects.

In guidance issued in 2016, the Council on Environmental Quality (“CEQ”)—the federal body charged with implementing NEPA—identified climate change as a …

Evaluating Climate Risk In Nepa Reviews: Current Practices And Recommendations For Reform, Romany M. Webb, Michael Panfil, Stephanie H. Jones, Dena Adler

Sabin Center for Climate Change Law

In recent years, policymakers, practitioners, and scholars have increasingly considered how climate change should factor into existing environmental review obligations, including review of U.S. federal agency actions under the 1969 National Environmental Policy Act (“NEPA”). Attention thus far has focused primarily on the critical question of how to account for an action’s contribution to climate change via direct, indirect, or cumulative greenhouse gas emissions. However, less focus has been given to the equally critical question of how actions will be affected by, and can prepare for, the impacts of climate change. This paper combines an extensive review of previously conducted …

Attribution Science In Takings Litigation, Daniel J. Metzger

Sabin Center for Climate Change Law

Climate science plays a central role in climate litigation, and cases under the Takings Clause of the United States’ and many state constitutions are no exception. In the climate context, takings cases to date have involved claims that challenge the constitutionality of both adaptation and mitigation measures. For instance, real estate developers have claimed that land use and zoning regulations that seek to reduce exposure to climate change impacts constitute regulatory takings. Property owners have claimed that restrictions on the development of fossil fuel infrastructure upset their investment-backed expectations. And property owners adversely impacted by climate-related flood control measures have …

U.S. Climate Litigation In The Age Of Trump: Full Term, Korey Silverman-Roati

Sabin Center for Climate Change Law

From beginning to end, the Trump administration pursued an agenda of climate deregulation. The administration aimed a portfolio of actions at weakening federal climate protections and promoting fossil fuels.1 The executive branch did so by aiming to revise and rescind all major Obama-era agency rules to regulate greenhouse gas emissions, leasing public lands for fossil fuel development, attempting to curtail climate impact consideration in National Environmental Policy Act and Endangered Species Act reviews, and withdrawing energy efficiency measures, among other climate deregulation actions.2 Collectively, this effort served to advance the view that humans are not causing serious climate change and …
