Coal phase-out: Global policy, economics, and regional transitions

Overview

Coal phase-out is an environmental policy focused on stopping the burning of coal in coal-fired power plants and other sectors. This policy is a key component of the broader fossil fuel phase-out strategy. The health and environmental benefits of phasing out coal, including the limitation of respiratory diseases and biodiversity loss, are considered greater than the associated costs. Coal is identified as the most carbon-intensive fossil fuel, making its phase-out critical for limiting climate change in line with the Paris Agreement.

The International Energy Agency (IEA) estimates that coal is responsible for over 30% of the global average temperature increase above pre-industrial levels. This significant contribution to global warming underscores the urgency of reducing coal dependency. The phase-out of coal is therefore seen as a vital step in achieving the climate goals established by international agreements.

Several countries have already taken action to phase out coal. The Powering Past Coal Alliance includes nations that have already stopped burning coal in their power plants. These early adopters demonstrate the feasibility of transitioning away from coal and provide models for other countries to follow. The alliance aims to accelerate the global phase-out of coal to mitigate its environmental and health impacts.

The policy of coal phase-out is not just about reducing carbon emissions. It also addresses the local and regional health impacts of coal burning, such as air pollution and water contamination. By reducing coal consumption, countries can improve public health outcomes and preserve ecosystems. The economic costs of phasing out coal are weighed against these benefits, with many analyses suggesting that the long-term gains outweigh the initial investments required for transition.

In summary, coal phase-out is a multifaceted environmental policy that plays a crucial role in the global effort to combat climate change. It is supported by scientific evidence and international agreements, and it is being implemented by various countries around the world. The policy aims to reduce carbon emissions, improve public health, and protect biodiversity, making it a key component of the global energy transition.

Economic and Health Impacts

Coal phase-out policies are driven by the significant health and environmental benefits that outweigh the economic costs. As the most carbon-intensive fossil fuel, coal's elimination is critical for climate change mitigation under the Paris Agreement. The International Energy Agency (IEA) estimates that coal accounts for over 30% of the global average temperature increase above pre-industrial levels. This environmental policy is a key component of the broader fossil fuel phase-out strategy. The health benefits include limiting respiratory diseases and reducing biodiversity loss. These advantages are considered greater than the associated economic costs.

External Costs and Economic Analysis

The economic analysis of coal phase-out involves assessing external costs, such as health damages and environmental degradation. In the United States, the external costs of coal have been estimated at $350 billion. These costs reflect the burden of health damages, including respiratory diseases, and environmental impacts. The concept of the Coasean bargain is relevant in this context, suggesting that if property rights are well-defined, parties can negotiate to internalize these externalities. However, the complexity of global coal markets often necessitates policy interventions to achieve optimal outcomes.

Health Damage Multipliers

Health damage multipliers provide a metric for comparing the health impacts of coal across different regions and time periods. These multipliers range from 0.8 to 5.6, indicating the variability in health outcomes. A higher multiplier suggests greater health damages per unit of coal burned. This variability is influenced by factors such as air quality, population density, and healthcare infrastructure. Understanding these multipliers is essential for prioritizing coal phase-out efforts in regions with the highest health burdens.

The economic and health impacts of coal phase-out are complex and multifaceted. While the costs of transitioning away from coal are significant, the benefits in terms of health improvements and climate change mitigation are substantial. Policies that effectively internalize the external costs of coal, such as carbon pricing and health-based regulations, can help achieve a more efficient and equitable transition. The Coasean bargain offers a theoretical framework for understanding how negotiations can lead to optimal outcomes, but practical implementation often requires robust policy measures.

Global Policy Frameworks and Alliances

The global effort to phase out coal is coordinated through several major policy frameworks and international alliances. The Powering Past Coal Alliance represents a significant coalition of countries and subnational entities committed to the orderly exit from unabated coal power. Participation in this alliance signals a political commitment to transitioning away from the most carbon-intensive fossil fuel, aligning national energy strategies with broader climate goals. The alliance serves as a platform for sharing best practices and accelerating the retirement of coal-fired power plants across different economic contexts.

Just Energy Transition Partnerships

The Just Energy Transition Partnership (JETP) provides a financial and policy framework to support major coal-dependent economies in their transition. These partnerships aim to mobilize public and private capital to accelerate the shift from coal to renewable energy sources while addressing social and economic impacts. The structure of JETPs involves commitments from donor countries and financial institutions to provide funding for grid modernization, renewable energy deployment, and workforce retraining. This approach recognizes that a successful coal phase-out requires not only technological changes but also significant economic support to ensure equity and stability in transitioning regions.

G7 Commitments and the Glasgow Climate Pact

Major economic powers have reinforced their coal phase-out ambitions through G7 commitments and the Glasgow Climate Pact. The Glasgow Climate Pact explicitly calls for the "phasedown of unabated coal power," marking a shift from earlier language that suggested a "phase-out." This nuanced wording acknowledges the varying levels of coal dependency among nations and the need for flexibility in implementation. The G7 nations have used their collective influence to encourage other major emitters to adopt similar timelines and policies, creating a ripple effect in global energy planning. These diplomatic efforts help to standardize the definition of a just transition and provide a template for national policy development.

IEA Recommendations and Flexibility Services

The International Energy Agency (IEA) emphasizes that the coal phase-out must be accompanied by strategic investments in flexibility services to maintain grid stability. As coal plants are retired, the energy system requires enhanced storage capacity, demand response mechanisms, and interconnections to manage the variability of renewable energy sources. The IEA recommends that policymakers prioritize these flexibility solutions to prevent the need for coal plants to remain online as backup generators. By integrating flexibility services into the broader energy transition strategy, countries can ensure a smoother and more cost-effective reduction in coal consumption. This technical guidance helps to bridge the gap between high-level political commitments and the operational realities of power system management.

How do European countries manage coal phase-out?

European nations have implemented diverse strategies to phase out coal, driven by the Paris Agreement and the need to limit global temperature increases. The International Energy Agency (IEA) estimates that coal is responsible for over 30% of the global average temperature rise above pre-industrial levels, making its removal critical for climate goals. The health and environmental benefits, including reduced respiratory diseases and biodiversity loss, are generally considered to outweigh the economic costs.

Country-Specific Transitions

Belgium was the first European country to stop burning coal, marking an early milestone in the continent's energy transition. The United Kingdom completed its phase-out in 2024, closing its last major coal-fired power plants. Germany has set a target year of 2038 for the complete cessation of coal, utilizing reverse auctions to determine which plants close first based on cost-efficiency. Other nations, including Denmark, Finland, Sweden, Portugal, Spain, Italy, and the Netherlands, have also established specific timelines or are actively reducing their reliance on coal-fired generation.

Phase-Out Status and Timelines

The following table summarizes the phase-out status and key years for selected European countries. These transitions are part of the broader fossil fuel phase-out effort, with some countries joining the Powering Past Coal Alliance to coordinate efforts.

These policies reflect a coordinated regional approach to reducing carbon intensity. By stopping the burning of coal in power plants, these countries aim to mitigate climate change and improve public health outcomes. The operational status of coal in some nations indicates that while the policy is active, the complete cessation of coal use is a gradual process involving infrastructure upgrades and economic adjustments.

What are the challenges in Asian coal transitions?

Asia presents the most complex landscape for coal phase-out, balancing rapid demand growth against mounting health and climate costs. China, the world’s largest coal consumer, has faced significant pressure to peak coal usage. The health impacts are severe, with studies indicating approximately 1.6 million deaths annually linked to coal-related pollution in the region (Global Health Estimates). Policy shifts in Beijing increasingly prioritize air quality and carbon neutrality, though the transition remains gradual.

India and External Costs

India’s coal dependency is driven by energy security and affordability. The International Energy Agency (IEA) highlights that the external costs of coal in India—encompassing health, climate, and water usage—are substantial. In 2025, the IEA reiterated the need for India to accelerate renewable integration while managing coal’s role in grid stability (IEA, 2025). The challenge lies in decoupling economic growth from coal consumption without compromising access.

Japan and South Korea

Japan’s reliance on coal surged post-Fukushima as nuclear output fluctuated. The country has set ambitious 2050 net-zero targets, requiring a steep decline in coal-fired generation. South Korea faces similar pressures, with coal demand growing to meet industrial needs. Both nations are investing in carbon capture and hydrogen co-firing to mitigate emissions while maintaining baseload power.

Vietnam and Regional Partnerships

Vietnam is advancing its transition through the Just Energy Transition Partnership (JETP), secured with $15.5 billion in international funding. This financial mechanism aims to accelerate renewable deployment and manage the social costs of phasing out coal. Other nations, including Indonesia, the Philippines, and Turkey, are also navigating complex coal transitions, balancing domestic mining interests with global climate commitments.

Coal phase-out in the Americas and Africa

Coal phase-out strategies in the Americas and Africa reflect diverse economic and geographic contexts. In Canada, provincial transitions have driven significant reductions in coal dependency. Ontario and Alberta have implemented aggressive policies to shift energy mixes, contributing to a national target of 90% non-emitting electricity. This transition involves replacing coal-fired generation with natural gas, nuclear, and renewable sources, aiming to reduce greenhouse gas emissions while maintaining grid stability. The policy framework emphasizes a gradual shift, allowing utilities to adapt infrastructure and manage economic impacts on coal-dependent regions.

United States

In the United States, the decline of coal has been largely market-driven, accelerated by the shale gas revolution. Cheaper natural gas displaced coal as the primary fuel for electricity generation, reducing coal's share of the power mix significantly. The Obama administration further supported this transition through regulatory plans, including the Clean Power Plan, which aimed to limit carbon emissions from existing power plants. These policies encouraged the retirement of older, less efficient coal plants and the expansion of natural gas and renewable energy capacity. The combination of market forces and policy interventions has led to a steady decrease in coal consumption, although regional variations persist due to differences in resource availability and state-level energy policies.

South Africa

South Africa faces unique challenges in its coal phase-out, given its heavy reliance on coal for both electricity generation and industrial use. The country has emphasized a "just transition" approach, aiming to balance environmental goals with social and economic stability. This involves decommissioning coal plants while addressing the impacts on coal mining communities and workers. Policies focus on diversifying the energy mix through renewable energy projects, such as solar and wind, and improving energy efficiency. The just transition framework includes social programs to support affected workers and regions, ensuring that the shift away from coal does not exacerbate existing inequalities. International partnerships and funding also play a crucial role in supporting South Africa's transition efforts.

New Zealand

New Zealand has implemented a moratorium on new coal-fired power stations, signaling a strategic shift towards cleaner energy sources. The Huntly power station remains a key coal-fired plant, but its future is subject to ongoing policy reviews and market conditions. The moratorium aims to reduce carbon emissions and encourage investment in renewable energy, such as hydro, wind, and geothermal power. This policy reflects New Zealand's broader commitment to climate change mitigation and energy security. The status of Huntly and other coal assets continues to evolve as the country balances immediate energy needs with long-term environmental goals.

Significance

The phase-out of coal is a central component of global fossil fuel reduction strategies, driven by the fuel's status as the most carbon-intensive energy source. The urgency of this transition is underscored by data from the International Energy Agency (IEA), which estimates that coal combustion is responsible for over 30% of the global average temperature increase above pre-industrial levels. This significant contribution to global warming makes the systematic retirement of coal-fired power plants critical to meeting the climate targets established in the Paris Agreement. The environmental policy aims to mitigate the extensive health and ecological damages associated with coal extraction and combustion.

Emissions Intensity and Fuel Comparison

The technical rationale for prioritizing coal over other fossil fuels lies in its high carbon output per unit of energy. Coal generates approximately 1 tonne of CO2 per megawatt-hour (MWh) of electricity produced. In contrast, natural gas, often viewed as a transitional fuel, emits roughly 500 kg of CO2 per MWh. This twofold difference in emissions intensity means that replacing coal capacity with natural gas or low-carbon alternatives yields immediate and substantial reductions in greenhouse gas concentrations. The shift is not merely about adding renewable capacity but actively displacing the most polluting incumbent source to accelerate decarbonization curves.

Geographic and Systemic Urgency

The impacts of coal-driven climate change are not distributed evenly, creating acute urgency for specific regions. Low-lying Pacific Islands face existential threats from rising sea levels and increased storm intensity, directly linked to the cumulative carbon emissions from global coal usage. For these nations, the coal phase-out is a matter of geographic survival and biodiversity preservation. Furthermore, the energy system itself is undergoing a structural shift. As variable renewables like wind and solar gain share, the role of traditional baseload suppliers is evolving. Coal plants are increasingly viewed not just as energy suppliers but as flexibility providers, a transition that complicates their phase-out but highlights the need for diversified grid management strategies to maintain stability while reducing carbon footprints.
