Heraldo de Madrid - South Korea pledges to phase out coal plants at COP30

Seoul announced its decision to join the Powering Past Coal Alliance (PPCA) of governments and organisations pushing to eliminate unabated coal as a power source, as Brazil hosts UN climate talks in Belem.

"Our long-term goal is to create a decarbonised green society where renewable energy takes up a large share in our power mix and use nuclear power as a complementary source, phase out coal and use gas as an emergency source," South Korea's Climate Minister Kim Sung-whan told reporters in the Amazonian city.

The pledge does not give a date for an end to all of South Korea's use of unabated coal, but represents the first official government commitment to stop building new unabated coal plants and to phase out existing ones.

"We will kickstart our coal phase-out," Kim said, adding that the pledge will "help the Alliance advance the coal transition worldwide".

Unabated refers to coal burned without any measures to reduce its emissions, such as carbon capture and storage. Most coal-fired power plants do not capture their CO2 emissions.

"Out of 61 existing coal power plants, 40 coal power plants are confirmed to phase out by 2040," the PPCA said in a statement.

The remaining 21 plants will have their closure date "determined based on economic and environmental feasibility", with a detailed roadmap to be finalised in 2026, the group added.

Asia's fourth-largest economy currently operates the world's seventh-largest coal fleet and is the fourth-largest coal importer, according to the PPCA.

The pledge demonstrates South Korea's "commitment to accelerating a just and clean energy transition", Kim said.

The transition will "create thousands of jobs in the industries of the future", the minister added.

- 'Must go even further' -

South Korea has already begun cutting its dependence on coal, with its share of electricity generation falling to 30.5 percent last year from 46.3 percent in 2009, according to energy think tank Ember.

On a global level, renewable energy overtook coal generation for the first time on record in the first half of 2025, according to Ember.

The new commitment builds on Seoul's 2020 pledge to reach carbon neutrality by 2050.

As part of that target, the government aims to reduce greenhouse gas emissions by 53–61 percent from 2018 levels by 2035, in line with global efforts to limit warming to 1.5C.

"A few years ago it would have seemed inconceivable that South Korea would be committing to phase out coal generation," said Richard Black, Ember's director of policy and strategy.

"But what's already happening in Korea, with coal power down by a third since the Paris Agreement was signed ten years ago, makes it now a logical choice," Black said.

Dozens of countries worldwide have pledged to phase out unabated coal.

South Korea is only the second government in Asia to join the PPCA, after Singapore.

"In these critical years of climate action, we must go even further and faster," British climate minister Katie White, who co-chairs the PPCA, said in Belem.

"Emissions from coal have not yet peaked, and we must consider the barriers faced by the developing world and ensure everyone feels the benefits of phasing out coal," White said.
