Asia today produces more than half of global CO₂ emissions, and the institutional choices it makes now will shape the planet’s climate trajectory through 2050. Asian policies follow variable combinations of adding renewables, limiting or reducing coal, financing transitions, and reforming electrical systems. This divide is not technical; it is political, and its consequences will be lasting.

The Essentials

  • Renewable technology is available everywhere in Asia; institutional architecture determines whether it replaces coal or is added alongside it.
  • Southeast Asia had 120 GW of renewable capacity in 2024, with projections between 360 and 600 GW by 2035 depending on scenarios (IEA Southeast Asia Energy Outlook 2026).
  • India produced 800 million tonnes of coal in 2022, rising 10% annually, while targeting 500 GW of non-fossil capacity by 2030; its electricity remains 75% coal-powered (Global Energy Monitor).
  • Japan and Indonesia have adopted, via JETPs (Just Energy Transition Partnerships), a logic of dated phase-outs, exposing their economies to cost risks different from those of Chinese or Indian phase-downs.
  • Comparison between these two architectures provides an empirical test of which logic better withstands the climate and economic shocks of the 2030-2050 decades.

Same Technology, Opposite Trajectories

When Carl Benedikt Frey publishes How Progress Ends (Princeton University Press), he poses an uncomfortable thesis for green transition enthusiasts: technological innovation alone is not enough to ensure progress. Institutions, monopolies, and power structures decide whether a wave of innovation leads to transformation or stagnation. Solar and wind turbines are cheap, available, scalable. Yet, Asian data illustrate exactly this diagnosis: same technology, two institutional architectures, two radically different trajectories.

China and India supported the international formulation of phased coal reduction without carbon capture, adopted in the Glasgow Climate Pact. Indonesia concluded a JETP with international partners, including Japan; this agreement aims for a peak in electrical sector emissions by 2030 and net-zero electricity by 2050, without fixing a general date for complete coal exit. The gap between these two approaches hinges on a fundamentally different institutional wager about the nature of risk to be managed.

Understanding why these choices were made, and what they reveal about the viability of each model, requires looking closely at the political and economic constraints of each country, not merely their declared climate objectives.

The Chinese and Indian Phase-Down: Defensible Rationale on a Short Horizon

Approximately 70% of Indian electricity production came from coal in 2021-2022; approximately 75% came from all thermal sources. According to India’s Ministry of Coal, production rose from 778.21 Mt in 2021-2022 to 893.19 Mt in 2022-2023, an increase of approximately 14.8%, then advanced 11.7% in 2023-2024. Simultaneously, New Delhi is targeting 500 GW of non-fossil capacity by 2030. These two realities are not contradictory; in Indian logic, they are complementary.

The phase-down logic rests on a resilience calculation. India must supply reliable and affordable electricity to a population of approximately 1.4 billion people; renewable development can help reduce exposure to fossil fuel imports, while coal can still contribute to system adequacy, but its maintenance carries price, emission, and stranded asset risks. Power outages have immediate consequences for industries, hospitals, households. Decarbonization, in this reading, cannot afford to be a wager on grid reliability.

China follows comparable logic, but at a different scale. It now installs more solar capacity each quarter than most countries install in a decade. Its smart grids are advancing. But its coal production remains at its highest, and industrial provinces resist any binding closure schedule. Coordination between the Party’s national objectives and regional coal interests constitutes a structural brake that neither technology nor central political will alone suffice to lift quickly.

This observation directly joins Frey’s thesis: coal’s vested interests—jobs, regional fiscal revenues, industrial supply chains—function as institutional brakes on progress, even when replacement technology is available and competitive. Economic history is replete with sectors where creative destruction was slowed not by lack of innovation but by organized resistance from threatened actors.

Japanese and Indonesian JETPs: A Wager on Pure Substitution

JETP logic is different in its structure. It formalizes transition and financing commitments; it does not necessarily include a date for total coal exit. Indonesia signed its JETP in 2022 at the Bali G20, aiming for $20 billion: $10 billion in public commitments from the International Partners Group and $10 billion in private investments to be mobilized via GFANZ, with expected support from multilateral banks. Japan has committed to its own transition with carbon neutrality targets for 2050; it aims to reduce coal’s share as much as possible and to progressively close inefficient plants, without having set a complete national coal exit.

Indonesia, the world’s third-largest coal producer, manages both its export interests and JETP commitments simultaneously. The two enter direct tension: every tonne of coal not extracted represents a real, immediate loss for a state whose public finances remain partially dependent on this rent. This subject, the difficulty in financing transitions when public budgets remain constrained, is a tension found in other climate policy architectures.

Japan illustrates another dimension of the problem. Its highly industrialized economy and energy import dependence since Fukushima in 2011 have created a specific risk structure: the country imports a major share of its fossil energy, making it vulnerable to international price shocks. Its JETP commitment responds partly to this energy security problem as much as to climate ambition. But closing coal plants without sufficient controllable capacity alternatives exposes its industrialists to supply disruption risks that phase-down competitors do not face to the same degree.

Southeast Asia, Between Two Models

Southeast Asia represents a particularly instructive observation field because it concentrates countries engaged in both logics, with already divergent results. According to the IEA Southeast Asia Energy Outlook 2026, the region had 120 GW of installed renewable capacity in 2024. The projection range for 2035 spans from 360 GW under declared policies to 600 GW if ambitious targets are achieved. This 360-600 GW gap is not technical: it reflects exactly institutional uncertainty.

Vietnam massively developed solar between 2019 and 2021 thanks to guaranteed feed-in tariffs; installed capacities exceeded grid capacities, causing congestion and solar production curtailment in certain zones and at certain hours. Evolution of private investment after guarantee replacement by competitive bidding remains difficult to establish. This case illustrates how poor institutional architecture can block an otherwise well-financed transition, consistent with Frey’s analytical framework.

The Philippines, Malaysia, and Thailand manage hybrid trajectories, accumulating renewables while delaying decisions on their existing coal plants. The ADB identifies carbon pricing as an important lever, among several systemic brakes on transition financing. The geography of climate risk—flooding, typhoons, droughts—nonetheless aggravates the economic stakes of inaction, as shown by the correlation between climate vulnerability and financial exposure that can be found in analysis of how climate risk geography becomes a geography of inequalities.

Which Architecture Better Withstands the 2030-2050 Years

The forward-looking question deserves to be posed directly, without claiming a definitive answer that current data do not yet permit.

The phase-down model offers short-term resilience: guaranteed controllable capacity, staggered transition costs, lower exposure to international financing contingencies. But it presents a growing structural risk: fossil assets will become stranded assets as carbon markets progress and storage technologies make renewables more reliable. A country whose 75% of electricity production remains coal-fired in 2030 will face adjustment costs far higher than if it had started substitution earlier. It will also face carbon border barriers; the EU’s carbon border adjustment mechanism is already in effect, which will directly affect the competitiveness of its industrial exports.

The phase-out model via JETP offers more limited long-term exposure to this risk. But successful coal exit depends on financing, storage, grids, flexibility, interconnections, dispatchable low-carbon resources, and market reform. On financing, disbursements may remain below announced commitments. Industrial battery storage deployment is already underway; uncertainties concern pace, costs, grids, and long-duration flexibility needs more than anything else.

Yet a different reading of this same picture exists. Economists specializing in industrial policy, whose work on Dani Rodrik on the conditions for industrial policy effectiveness in emerging countries constitutes a useful framework, emphasize that the JETP creates formalized commitments, coordination mechanisms, and investment plans without necessarily creating legally binding obligations. Formalizing a dated commitment, even if not immediately honored, alters private investor expectations and makes reversal politically more costly. This is an institutional mechanism that phase-down logic does not activate in the same way.

These two readings are not irreconcilable. They show that international financing can greatly strengthen JETP credibility, but must be accompanied by national technical, regulatory, and institutional conditions. Institutions lacking sufficient capacities and resources risk failing to transform energy trajectories; their effectiveness also depends on financing, applicable rules, and implementation capacities.

The Signals That Will Distinguish Trajectories

Several indicators in coming years will allow assessment of which architecture delivers on its promises.

The first is the effective JETP disbursement rate. If financing announced for Indonesia and other transitioning economies materializes at least 80% of initial commitments by 2027, phase-out logic gains empirical credibility. If gaps persist, concerned governments will have real economic arguments to revisit their commitments.

The second is grid capacity. The IEA identifies grids, storage, and interconnections as major constraints, among several transition brakes. A country that massively installs solar without renovating its grid reproduces Vietnam’s error. Public investments in grids, not solely in production capacity, will constitute a more reliable indicator of transition solidity than installed GW.

The third is the evolution of capital costs for fossil projects in Asia. Major development banks, including the Asian Development Bank, have progressively tightened financing conditions for new coal plants. If this movement accelerates under European and American sustainable finance regulations, the comparative cost of maintaining fossil assets will mechanically increase, altering the equation even for phase-down supporters.

These three signals will converge or diverge by 2028-2030. Their combined reading will inform more about model viability than any climate projection modeled today. Private capital, which arbitrates between existing rents and new growth trajectories, will constitute the most difficult arbiter to ignore. The institutional architecture that sustainably attracts private financing for decarbonization, at scale sufficient for climate physics to follow balance sheet logic, will determine this transition’s outcome.
