Investor–State Dispute Settlements: A Hidden Handbrake On Climate Action, Lea Di Salvatore, Lorenzo Cotula, Anirudh Nanda, Chloe Yuqing Wang

Columbia Center on Sustainable Investment

To achieve the Paris Agreement’s climate goals, states must move away from fossil fuels. But investor–state dispute settlement (ISDS) — a system that enables companies to take states to international arbitration — can increase the cost of this transition.

Our research shows that fossil fuel companies have historically secured at least US$82.8 billion in damages and large sums continue to be invested in fossil fuels worldwide. To address this problem, investment governance must be harmonised with global climate goals.

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 …

Climate Change, Coming Soon To A Court Near You – Report Four: International Climate Change Legal Frameworks, Maria Cecilia T. Sicango

Sabin Center for Climate Change Law

In 2020, the Paris Agreement is the pinnacle of international law on climate change. It orchestrates global climate action over the coming decades. Countries agreed to limit global warming to well below 2ºC above preindustrial times, closer to 1.5ºC. Humankind will only achieve this temperature goal if we domesticate our international climate commitments. Judges have proven to be instrumental in holding their governments accountable for their climate pledges. Report Four of this four-part series explores the nature of the Paris Agreement, its history, and the framework of international instruments and international legal principles that support global and domestic climate action.

Climate Change, Coming Soon To A Court Near You – Report Three: National Climate Change Legal Frameworks In Asia And The Pacific, Dena Adler, Hillary Aidun, Michael Burger, Ama Francis, Briony Eales, Maria Cecilia T. Sicango

Sabin Center for Climate Change Law

National legal and policy frameworks underpin international climate action because they are the backbone of domestic responses to the climate emergency. Unless they support global objectives, local climate action stalls. Concerned by sluggish national responses to climate change or injured by its impacts, citizens are filing lawsuits, making courts central to national climate governance. To adjudicate these lawsuits, courts require current information about their climate change legal and policy frameworks. This report provides holistic syntheses of the climate legal and policy frameworks of 32 countries in Asia and the Pacific and discusses key legislative trends and climate-relevant constitutional rights.

The Contact Group On Somali Piracy: An Unlikely Model For Protecting The Environment?, Susan Biniaz

Sabin Center for Climate Change Law

International environmental law covers a wide range of subjects, is extremely detailed, and evolves very rapidly. No wonder it is challenging for practitioners to keep up with developments. An expert in marine pollution regimes may be unaware of the latest initiatives on forest conservation. Given how hyper-specialized the climate world has become, an expert on mitigation may be only mildly aware of recent advances in adaptation. And neither may be in a position to keep up with innovations in international law more broadly.

Deep knowledge has its advantages, but also some drawbacks. When we are faced with the need to …

After Madrid, W[H]Ither The Cop?, Susan Biniaz

Sabin Center for Climate Change Law

With Madrid behind us and Glasgow on the horizon, it is a good time for Parties and others to consider the future of the annual COP. (By “COP,” I mean the climate conference writ large, rather than the “Conference of the Parties,” the narrower technical name for the Parties to the UN Framework Convention on Climate Change.) Madrid, while a remarkably successful venue in terms of logistics, left many not only disappointed at the Parties’ failure to reach agreement and signal an increase in ambition but also confused:

• Why was there such a disconnect between the scientific imperative (as well …

Free-Movement Agreements & Climate-Induced Migration: A Caribbean Case Study, Ama Francis

Sabin Center for Climate Change Law

Climate-induced migration has become a global challenge. Climate change intensifies the frequency and severity of disasters, thereby increasing the number of people displaced by extreme weather events. Adverse climate impacts are already exacerbating patterns of human mobility, and will do so to a greater degree in the future. The Internal Displacement Monitoring Center (IDMC) reports that approximately 265 million people have been displaced by natural hazards since 2008. Over 17 million people were internally displaced by disasters in 2018 alone. While the majority of climate migrants are displaced within their home countries, many people are forced to move abroad.

The Renewable Power Of The Mine, Nicolas Maennling, Perrine Toledano

Columbia Center on Sustainable Investment Staff Publications

Access to affordable and reliable energy is key for the mining sector and with rising demand for minerals and falling ore grades, energy demand is estimated to increase by 36% by 2035. Today, energy produced and procured by mining companies is mostly fossil fuel based. This will have to change if the sector is to contribute to the decarbonization of the world economy, needed for countries to meet the target adopted at the Paris Agreement of keeping global temperatures from rising more than 1.5-2 degrees Celsius.

At the same time, the costs of solar, wind and battery storage systems have …

Il Contributo Delle Compagnie Oil & Gas Nel Raggiungimento Degli Obiettivi Energetici E Climatici (How Oil And Gas Companies Can Help Meet The Global Goals On Energy And Climate Change), Lisa E. Sachs, Nicolas Maennling, Perrine Toledano

Columbia Center on Sustainable Investment Staff Publications

Nel settembre 2015, i governi di tutto il mondo hanno adottato17 Obiettivi di Sviluppo Sostenibile (Sustainable Development Goals – SDG) e, pochi mesi dopo – a dicembre – hanno firmatol’Accordo di Parigi. Queste azioni sono la riprova delrafforzamento del consenso globalecirca la necessità di frenare il cambiamento climatico indotto dalle attività antropiche e dipromuovere uno sviluppo sostenibilesu scala mondiale. I due concetti sono infatti strettamente legati: l’urgenza di affrontare il cambiamento climatico va inquadrata nella cornice degli sforzi globali tesi a ridurre la povertà, promuovere la crescita economica, rispettare i diritti umani e di inclusione sociale.

Human Rights And Article 6 Of The Paris Agreement: Ensuring Adequate Protection Of Human Rights In The Sdm And Itmo Frameworks, Romany M. Webb, Jessica A. Wentz

Sabin Center for Climate Change Law

Article 6 of the Paris Agreement recognizes the right of Parties to cooperate in the implementation of their nationally determined contributions (NDCs) through both market- and non-market-based approaches. One market-based approach is outlined in Article 6.2 which provides for “the use of internationally transferred mitigation outcomes [(ITMOs)] towards” NDCs. This is widely seen as establishing a “bottom-up” approach, whereby “mitigation outcomes,” representing emission reduction credits, can be transferred internationally and then become ITMOs. It can be contrasted with other market-based approaches that are “top-down,” involving centralized programs supporting emission reduction projects. One such program is created in Article 6.4 of …

What Happened To Byrd-Hagel? Its Curious Absence From Evaluations Of The Paris Agreement, Susan Biniaz

Sabin Center for Climate Change Law

In the midst of the negotiations leading to the Kyoto Protocol in 1997, the U.S. Senate adopted the “Byrd-Hagel Resolution,” co-sponsored by Senators Robert Byrd of West Virginia and Chuck Hagel of Nebraska. Passed by a vote of 95-0, it reflected the Senate’s view that the international climate change agreement then being negotiated by the Clinton Administration was not on the right track. Specifically, it signaled dissatisfaction with an agreement that would contain legally binding greenhouse gas emissions commitments for developed countries without such commitments in the same time period for developing countries.

By its terms, the Byrd-Hagel Resolution applied …

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 …

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 …

How Oil And Gas Companies Can Help Meet The Global Goals On Energy And Climate Change, Lisa E. Sachs, Nicolas Maennling, Perrine Toledano

Columbia Center on Sustainable Investment Staff Publications

The sustainable development goals (SDGs) and the Paris Agreement lay out a global consensus on the need to curb human-induced climate change and to achieve sustainable development. These concepts are linked. The urgency of addressing climate change is critical for global efforts to reduce poverty and advance sustainable development, but also climate-change mitigation must be pursued in a manner consistent with ending poverty, promoting economic development, respecting human rights, and ensuring social inclusion. CCSI and the UN Sustainable Development Solutions Network (SDSN) have published a briefing note summarizing the ways in which international oil and gas companies can help expand …

Transparency And Icao's Aviation Offsetting Scheme: Two Separate Concepts?, Aoife O'Leary

Sabin Center for Climate Change Law

The International Civil Aviation Organisation (ICAO), the UN specialised body for aviation, is developing a scheme to reduce the climate impact of aviation emissions, the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA). From 2021, participating countries will (voluntarily at first) offset any growth in CO2 aviation emissions above the level those emissions have reached in 2020. This paper does not consider the climate implications of the scheme but rather focuses on whether the governance structure under which the scheme is being developed – especially its transparency and opportunities for public participation – meets an appropriate standard, given the …

10 Questions To Ask About The Proposed “Global Pact For The Environment”, Susan Biniaz

Sabin Center for Climate Change Law

There is no doubt that more needs to be done, both nationally and internationally, to protect the environment. It is tempting, particularly during the Trump era, to welcome any concerted effort to do so. The issue is whether the proposed “Global Pact” is the right vehicle for enhancing environmental protection.

The Global Pact was launched this past June in Paris, with support from, among others, President Macron of France and former California Governor Arnold Schwarzenegger. At least in its preliminary state, the Pact reflects broad, cross-cutting principles in legally binding form. France intends to seek support at the upcoming UN …

A Call To Action For New Yorkers, Jeffrey Gracer, Michael Mahoney

Sabin Center for Climate Change Law

President Donald Trump's announcement last week that he will begin the process of withdrawing the United States from the Paris Climate Change Agreement is a deeply disappointing decision, one that jeopardizes the future of the planet and cedes U.S. leadership on international climate action.

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. …

I Beg To Differ: Taking Account Of National Circumstances Under The Paris Agreement, The Icao Market-Based Measure, And The Montreal Protocol’S Hfc Amendment, Susan Biniaz

Sabin Center for Climate Change Law

This paper explores the different ways in which negotiators to three recent environmental instruments accounted for different national circumstances in formulating commitments and other aspects of cooperation in the instruments. The author finds that the negotiators of these instruments have significantly expanded the arsenal of differentiation tools based on considerations pertaining to logic, fairness, limited capacity, and negotiating leverage.

International Investment Agreements: Impacts On Climate Change Policies In India, China And Beyond, Lise Johnson, Brooke Güven

Columbia Center on Sustainable Investment Staff Publications

Mitigating and adapting to climate change will require a fundamental reorientation of our global economy as we move away from fossil fuels and transition to a low carbon and climate-resilient world. This reorientation depends on government actions to help catalyze and channel financial flows in new directions and away from business-as-usual practices.

International investment agreements (IIAs) – treaties that now number over 3,000 and have the objective of promoting and protecting cross-border investment flows_could potentially play a key role in these efforts to scale up and (re)direct investments to meet climate change mitigation and adaptation needs. As presently drafted and …

The 2015 Paris Agreement On Climate Change: Significance And Implications For The Future, Hari Osofsky, Lisa Benjamin, Michael B. Gerrard, Jacqueline Peel, David Titley

Faculty Scholarship

On December 12, 2015, nearly 200 countries created a major new agreement on climate change, accompanied by national commitments to act. The Paris Agreement has rightly been celebrated as a breakthrough, but was unquestionably constrained by the need for compromise, and its details will continue to be developed at the international, national, and local levels. On January 9, 2016, a panel of expert commentators and delegation members from a variety of national jurisdictions convened at the annual American Association of Law Schools meeting to analyze the Paris Agreement; they considered how the agreement evolved from prior efforts, the structure of …

A Mitigation Based Rationale For Incorporating A Climate Change Impacts Fee Into The Federal Coal Leasing Program, Michael Burger

Sabin Center for Climate Change Law

This paper describes the legal and policy rationale for imposing a fee on federal coal that reflects the costs of the climate change impacts generated by that coal. It notes that the federal government has a duty to mitigate climate impacts from the federal coal leasing program, and that the Department of Interior (“Interior”) and the Bureau of Land Management (“BLM”) have ample authority to impose a climate change impacts fee on coal leases as a form of compensatory mitigation for those coal leases. The paper also discusses technical issues that should be considered when assessing the effectiveness of this …

Comma But Differentiated Responsibilities: Punctuation And 30 Other Ways Negotiators Have Resolved Issues In The International Climate Change Regime, Susan Biniaz

Sabin Center for Climate Change Law

International climate change negotiations have a long history of being contentious, and much has been written about the grand trade-offs that have allowed countries to reach agreement. Issues have often involved, for example, the level of ambition, differentiated treatment of Parties, and various forms of financial assistance to developing countries.

Lesser known are the smaller, largely language-based tools negotiators have used to resolve differences, sometimes finding a solution as subtle as a shift in the placement of a comma. These tools have operated in different ways. Some, such as deliberate imprecision or postponement, have “resolved” an issue by sidestepping it …
