Climate and the Earth System

Climate and the Earth System is no longer a distant environmental concern; it is an existential challenge that shapes the future of human civilization and the living planet itself. Climate change is accelerating disruptions across ecosystems, economies, and societies, amplifying inequality, insecurity, and vulnerability—especially for those least responsible for the crisis. In a world of fragmented governance and short political time horizons, inaction is no longer a neutral choice; it is a decision with irreversible consequences.

Yet this moment is also one of possibility. Scientific knowledge, economic tools, and policy solutions already exist to change course—if they are matched by political will and effective global cooperation. Addressing climate change demands more than emissions targets: it requires coherent climate governance, just economic transitions, protection of vulnerable populations, and credible international treaties capable of enforcement.

The Global Governance Forum argues that safeguarding the Earth system must become a core function of global governance. In A Second United Nations Charter, we propose the creation of an Earth System Council to provide legal authority, coordination, and long-term stewardship at the planetary level. The choices we make now will define the legacy we leave to future generations.

Introduction

Climate change confronts humanity with a shared test of responsibility, foresight, and collective action. As pressures on the Earth system intensify—through rising temperatures, ecosystem collapse, economic disruption, and widening human vulnerability—the limits of existing institutions and fragmented approaches are becoming unmistakably clear. What is at stake is not only environmental stability, but the conditions for peace, prosperity, and justice across generations.

Responding to this challenge requires more than isolated policies or voluntary commitments. It calls for durable systems of global cooperation capable of aligning science, law, economics, and ethics around the long-term stewardship of the planet. In A Second United Nations Charter, the Global Governance Forum therefore proposes the creation of an Earth System Council to provide strategic coordination, legal authority, and accountability at the global level.

The sections that follow explore how such a transformation might take shape in practice. Drawing on the work of leading experts, this page examines four interlinked dimensions of the climate challenge: Climate Governance, the Economics of Climate, Climate and Vulnerable Populations, and Climate Treaties and Agreements. Together with selected episodes of the Global Governance Podcast, these contributions aim not only to clarify the risks we face, but to illuminate viable pathways toward a more resilient, equitable, and sustainable planetary future.

A new Earth System Council

This new 54-member Council is one of the new governance structures proposed by A Second United Nations Charter. It bridges a critical gap in environmental governance and seeks to remedy the very significant fragmentation in this domain. Its aim is to provide overall direction for this immensely important area of governance and problem solving for the future of the planet.

While no institutional structure can substitute for an absence of political will, the Council will help close the institutional gap between current global environmental structures and what is necessary to meet the planet’s life-threatening global environmental challenges. The Earth System Council we propose will have the stature and authority necessary to begin the process of harmonizing and coordinating global environmental governance and international environmental law and treaties. Rather than starting ab initio, the proposed organizational structure builds upon the existing global institutional framework. It is proposed that the United Nations Environment Assembly be subsumed into the United Nations Earth System Council to create a more robust organization that will have the institutional ability to effectively promote the coordination and harmonization of global environmental law and policy. Over time, the Earth System Council would have the ability to consolidate the highly fragmented global environmental governance architecture. Similarly, the United Nations Environment Programme can be incorporated into a more empowered Global Environmental Agency that will operate under the aegis of the Council and have the ability to carry out its mandates. These institutional innovations will foster the creation of international environmental laws and judicial mechanisms capable of tackling the planet’s multiple environmental crises.

A Second UN Charter: Chapter XII – The Earth System Council

Article 2 (Functions and Powers)

The Earth System Council shall operate under the direction of the General Assembly and the Parliamentary Assembly and will assume the powers and functions of the United Nations Environment Assembly that will cease operations. The Earth System Council has functions such as:

Climate Governance

In Governing the Planet: Why We Need an Earth System Council Now (2025), Arthur Lyon Dahl argues that there is no mention
of the environment in the present UN Charter. It was only in 1972 that the UN organized its Conference on the Human Environment in Stockholm and, 20 years later the UN Conference on Environment and Development in Rio.

The latter adopted Agenda 21 and the Conventions on Climate Change, Biodiversity and Desertification. Today, there are more than 500 multilateral environmental agreements, which are highly fragmented and unable to prevent or reverse the existential threats of climate change, biodiversity loss, and global pollution. Patrícia Nogueira Rinaldi also discusses in The need for an Earth-centered approach to sustainable development: Towards a United Nations Earth Assembly (2023) that, despite this growing awareness, the UN lacks a robust mandate to implement a holistic approach and to efficiently address the deterioration of ecosystems, loss of biodiversity, and climate change. For these reasons, multiple stakeholders – member states from the Global South, civil society, and academia – are advocating for the creation of a UN Earth Assembly. This multilateral space would have the mandate of mainstreaming the implementation of an Earth-centered paradigm across all sustainable development efforts. Currently, 40 countries have passed over 200 laws that recognize the rights of Nature, most of them in Latin America and Europe.

As discussed in Filling a Critical Gap in Global Environmental Governance (2022), to give coherence to this dispersed body of international law, we need a fourth UN Pillar: The Earth System Council. Other pillars include peace and security, economic and social development, and human rights. This new entity would bridge a critical gap in international environmental governance and remedy the significant fragmentation in the current system. The Council would provide strategic direction and coordinated action for the governance of the global commons and the Earth System.

The Economics of Climate

In Climate Change & World Economy: When an Irresistible Force Meets an Immovable Object (2023), Arthur Dahl explained that climate change is accelerating with irresistible force beyond the most alarmist scientific predictions, with a giant leap in global ocean temperatures and record heat waves around the world. Yet fossil fuels remain highly subsidized, and producing countries and companies are expanding production and making enormous profits. No one wants to abandon proven energy sources and systems that are so profitable, yet we still need technological breakthroughs and major transformations in present infrastructure and products. How can we respond? Again science provides some guidance. The latest Club of Rome report in 2022 “Earth for All: A survival guide for humanity” defines the five transformations needed in economics to avoid economic and social collapse. These include eliminating poverty, reducing inequality, empowering women, transforming food systems, and turning around the energy system.

In Why a Carbon Tax is the Best Way to Mitigate Climate Change (2020) Augusto Lopez-Claros argued how taxing carbon emissions can be a strong incentive for an energy transition at a global scale. These taxes are charges on the carbon content of fossil fuels and they lead to rises in the price of coal and other fossil fuels through the elimination of widespread subsidies, which have tended to underprice these energy sources. A carbon tax is effective because it makes it costlier to emit GHGs and provides incentives for energy users to shift to greener sources and to avail themselves of other opportunities, ranging from reducing the energy intensity of power generation by switching from coal to natural gas or renewables, to curbing electricity use through the acquisition of more energy efficient appliances. A carbon tax could be supported by other revenue collection initiatives which could generate potentially large resources for climate change mitigation, such as a global Tobin-like tax on financial transactions, as proposed, for instance, in Lopez-Claros, Dahl and Groff (see Chapter 12).

Climate and Vulnerable Populations

In “Thinking About the Summit of the Future: Shaping its Agenda – Part II: Global Environmental Governance and Gender Equality”(2024), Arthur Lyon Dahl and Amanda Ellis highlight how the accelerating “triple planetary crisis” of climate change, biodiversity loss and pollution is driving global insecurity, with the poorest and least resilient communities bearing the highest costs. Climate change most severely impacts those least responsible for its causes: women, Indigenous peoples and vulnerable communities in fragile and low-income states. Dahl and Ellis emphasise that addressing these disparities requires a global pact for people and planet grounded in justice, equity and accountability. Therefore, countries that have benefited most from decades of planetary exploitation have a duty, under the principle of common but differentiated responsibilities, to lead a just transition to a sustainable future. They call for strengthening UNEP and the UN Environment Assembly, codifying the human right to a clean, healthy and sustainable environment, and elevating environmental governance to parity with peace, development and human rights.

Similarly, Diana Chacón in “From Overlooked to Empowered: Women’s Voices in Climate Action Policy” (2023) exposes the gender blindness of most national climate plans, few of which address reproductive health, gender-based violence or women’s livelihoods. Although women remain underrepresented in decision-making, Chacón highlights how inclusive female leadership has produced tangible environmental gains. Countries with stronger gender-equality frameworks such as Sweden and Norway likewise show more effective climate governance, underscoring the link between gender inclusion and climate performance. Carly Kabot’s “No Status, No Safety: Climate Migrants in Legal Limbo” (2025) turns to the absence of binding international protection for another vulnerable group – climate-displaced populations, Although climate change may force millions to flee, existing law fails to recognize them as refugees. This gap in protection leaves climate-displaced people in a position of profound legal vulnerability and illustrates the urgent need for a coherent international response.

Climate Treaties and Agreements

Philip Landrigan and Sarah Stimson Karis in The United Nations Plastics Treaty – A Global Agreement to End Plastic Pollution: What is it? Why is it Needed? (2023), observe that plastics have become embedded in nearly every aspect of modern life: preserving food, advancing medicine, and reducing the weight of vehicles and aircraft. Yet this very success has produced severe environmental and health consequences. Recognizing the scale of the problem, countries launched negotiations in 2022 for a legally binding United Nations Global Plastics Treaty, intended to match the ambition of the Paris Agreement. The authors review the treaty’s goals, including establishing a global cap on virgin plastic production with clear targets and timelines, introducing bans or strict limits on unnecessary single-use plastics, and expanding extended producer responsibility so manufacturers are financially and operationally accountable for end-of-life management. They further proposes a standing science-policy advisory body to support implementation and periodic review.

Unfortunately, as Joshua Lincoln details in “After UN Talks Collapse, a Narrow Path to a Global Plastics Treaty” (2025), successive negotiation rounds have failed to produce an agreement due to sharp divisions over ambition and scope. Lincoln reviews how a coalition of small island states, the EU, Kenya and Chile pressed for binding limits on plastic production and recognition of Indigenous rights, while oil- and plastic-producing states (Saudi Arabia, Russia, the United States, China and India) opposed global obligations and sought to restrict the treaty to waste management. Lincoln notes that although consensus now appears out of reach, alternative pathways remain possible, such as negotiations outside a UN framework or consumer-driven initiatives.

Another milestone in International Environmental Law was noted by Arthur Dahl in “High Seas Treaty Major Advance in Ocean Law” (2023). After many years of effort and growing scientific evidence of unique and vulnerable biological resources, governments have finally agreed to a new high seas treaty on marine biological diversity under the UN Convention on the Law of the Sea. Provisions ensure equitable sharing of benefits with developing countries concerning marine genetic resources, capacity building and transfer of technology. They also provide for marine protected areas and environmental impact assessments of development activities. The new convention will permit protecting the unique life of the water column and ocean bottom. It will also be critical in meeting the goal to protect 30 percent of the ocean, which was agreed to under the Convention on Biological Diversity.

Although public support for sustainable action is strong, political will and recognition of our intergenerational responsibilities remain weak. She emphasises that the costs of inaction far exceed those of immediate change and that knowledge must now be matched by enlightened political leadership.

Johan Rockström on the Climate Challenges We Face

Johan Rockström is one of the world’s leading authorities on the impact of climate change. In a broad ranging interview with Ambassador Amanda Ellis, he highlights the importance of the removal of energy subsidies and the introduction of a carbon tax, the need for accountability and the development of monitoring mechanisms for emissions reductions promises, which should become legally binding. We also need to develop carbon markets for nature—beyond fossil fuels—and to embed greater fairness and equity in the way we address climate change globally. Learn more on:
