South Korea must exit coal by 2029 to be in line with the Paris Agreement
South Korea is one of the world’s top greenhouse gas emitters and currently home to 60 coal power plant units, with seven new coal power units accounting for 7.27 GW under construction. The country is also one of the world’s largest importers of coal, next to China, India, and Japan, with Australia and Indonesia as its biggest exporters.
According to the study, titled “Transitioning towards a coal-free society: Science-based coal pathway for South Korea under the Paris Agreement,” without a change in policy, Korea’s coal power generation would exceeded power sector carbon budgets for coal in line with the Paris Agreement by 2.5 times. If the seven new coal power units currently under construction go online, then the country will exceed this carbon budget by 3.17 times.
Figure 1 – Coal power plant emissions pathways for South Korea. Emissions from operating coal capacity are calculated based on proposed retirement age (30 years) and historical utilisation rates (81%), and reported emissions intensities per combustion technology and coal type. Paris Agreement compatible pathway for South Korea is a result of the downscaling of the results for the OECD from the IEA ETP B2DS scenario to South Korea with the SIAMESE model.
Despite the encouraging signs that a transition to a coal-free electricity mix may be starting, South Korea has no concrete national commitment, roadmap, or policy instrument to accelerate phasing out coal, and no systematic framework to ease the transition.
The report finds that in order to be in line with the Paris Agreement, South Korea will need to retire its operating power plants much earlier than the currently proposed age of 30 years and/or dramatically reduce their utilisation rate. Every new coal unit that comes online would only increase the already large gap between Korea’s emissions and its Paris Agreement compatible pathway, lock-in emissions for decades and increase the risk of stranded assets.
Paola Yanguas Parra, climate policy analyst and one of the authors of the report, commented: “Public pressure to end coal use and government regulations aimed at tackling air pollution are all positive signs that South Korea is moving towards phasing out coal domestically. What is equally important, however, is rethinking its role in tackling climate change on the international stage. South Korea is still one of the biggest funders of new coal plants in South East Asia but as the world moves away from fossil fuels, it would be much smarter to re-evaluate and focus on renewables.”
Sejong Youn, director at South Korea-based climate policy organisation Solutions for Our Climate, explained that it has now been “scientifically proven that the expansion of coal power generation will have significant economic and environmental burden” on Korea, emphasizing that “we must stop new coal power projects and make concrete plans to replace them with renewable energy within the next 10 years.”
All greenhouse gas emissions could peak in 2023
A new report finds maintaining current solar, wind and electric vehicle growth rates could lead to peak emissions in 2023.
Oil and gas majors could have paid for their share of climate loss and damage and still earned 10 trillion USD: new report
Global climate damages from emissions associated with the top 25 oil and gas ‘carbon majors’ between 1985 and 2018 are estimated at 20 trillion USD compared to the 30 trillion USD they earned over the same period, according to a new report released today by international think tank Climate Analytics.
A 1.5˚C pathway for the Philippines power sector entirely feasible: analysis
With the right international funding and policies in place, the Philippines could transition its’ power sector to near-100% renewable energy without compromising on the costs of electricity, reducing its reliance on expensive imports of both coal and gas, and creating up to a million jobs by 2050.
State of Climate Action report finds progress lags on every measure except EV sales
Global efforts to limit warming to 1.5°C are failing across the board, with recent progress made on every indicator — except electric passenger car sales — lagging significantly behind the pace and scale that is necessary to address the climate crisis.
Governments plan to produce double the fossil fuels in 2030 than the 1.5°C warming limit allows
The Production Gap Report finds governments plan to produce around 110% more fossil fuels in 2030 than would be consistent with limiting warming to 1.5°C, and 69% more than would be consistent with 2°C.
Beetaloo fracking and Middle Arm emissions wildly underestimated: analysis
An independent analysis of the projected emissions from the Northern Territory's proposed Beetaloo Basin gas fracking project — and the associated Middle Arm LNG precinct in Darwin Harbour — has found they've been gravely underestimated, as have the availability of offsets to deal with them.

We pay tribute to the highly revered climate expert and advocate Saleemul Huq, who passed away suddenly this Saturday.
Comic artists respond to the climate crisis
Three leading comic creators have collaborated with the Horizon Europe project, CONSTRAIN, to develop comics exploring the climate change challenge.
Changes to the jet stream could trigger simultaneous crop failures impacting global food security
This new study finds that the jet stream – air currents in the upper atmosphere – can synchronise extreme weather caused by climate change, resulting in crop failures in multiple countries at the same time.
At least 1.5 TW of new wind and solar capacity needed each year by 2030 to meet 1.5°C limit sustainably
Our new analysis, which applies sustainability limits and minimises the need for carbon dioxide removal, finds new wind and solar needs to be installed five times faster by 2030 at a rate of 1.5 TW a year to limit global warming to 1.5°C.
Limiting warming using solar geoengineering is a 100 year plus commitment, new study
New peer reviewed research shows that if solar radiation management – where higher amounts of sunlight are reflected back to space through artificially altering either the Earth’s surface or the atmosphere – is deployed to limit warming to 1.5°C without emissions cuts beyond those currently envisioned by governments, it would have to be maintained for at least a hundred years.
