South Korea has unveiled a 10-year Korea-Green Transformation (K-GX) strategy designed to accelerate decarbonization while positioning domestic industries for growth in global clean technology markets. Announced on October 7, 2026, the plan targets approximately 1,000 trillion won (around $747 billion) in government-backed funding between 2026 and 2035, alongside a separate 220 trillion won in private-sector investment for designated projects. The government’s funding framework includes 200 trillion won in fiscal resources and more than 790 trillion won in climate finance. These figures represent different financing channels within the overall strategy, while the private investment target is additional.
A central target is to reach 100 gigawatts (GW) of renewable energy capacity by 2030. South Korea plans to accelerate solar and wind deployment while expanding the electricity network needed to transport power from generation sites to consumers. The strategy includes upgrading existing transmission lines to increase capacity and developing direct-current transmission technologies to connect renewable energy zones with demand centers. These measures are intended to address grid constraints that could otherwise slow renewable integration and industrial electrification.
The industrial component of K-GX focuses on five major emissions-intensive sectors: steel, petrochemicals, cement, semiconductors and displays, and refining. Rather than relying solely on renewable electricity procurement, the government intends to support changes to industrial production processes, cleaner feedstocks and technologies that reduce emissions at their source. For steel, the plan includes a 300,000-tonne hydrogen-based ironmaking demonstration by 2030, supporting South Korea’s ambition to develop commercial-scale hydrogen-reduced steel production. Petrochemical and refining industries are expected to advance electrified processes and cleaner fuel use, while cement manufacturers will pursue lower-carbon materials and production technologies.
Solar manufacturing is another strategic priority. The government plans to support commercialization and mass production of next-generation tandem solar cells by 2028, while strengthening domestic supply chains for critical solar equipment. Tandem cells combine different photovoltaic materials to capture a broader portion of the solar spectrum than conventional single-junction cells, offering a route to higher conversion efficiency. The strategy also identifies batteries, wind power, small modular reactors (SMRs), power equipment, power semiconductors, heat pumps, hydrogen and carbon capture, utilization and storage (CCUS) among the 10 priority green industries. The government intends to support technology development, commercialization and domestic manufacturing to improve the international competitiveness of these sectors.
Transport electrification forms another measurable part of the programme. South Korea aims for electric and hydrogen-powered vehicles to account for more than 70% of new vehicle sales by 2035. The proposed transition extends beyond passenger cars to public transport, two-wheelers, construction equipment, ports and shipping. The government also plans to adjust vehicle incentive structures and support charging and related infrastructure to encourage adoption. These measures connect clean-energy deployment with a wider effort to reduce petroleum dependence across the transport sector.
Financing is central to the strategy’s implementation. The government plans to expand the Climate Response Fund and establish a framework for green government bonds by the first half of 2027. Alongside the public funding and climate finance commitments, the additional 220 trillion won in private investment is intended to mobilize capital for designated K-GX projects. The government is also developing support for climate technology startups, including research and development assistance, demonstration facilities and financing packages that could reach 10 billion won for eligible companies. The effectiveness of the programme will depend on how these financing commitments translate into projects, production capacity and measurable emissions reductions.
The plan also addresses the regional and workforce implications of industrial decarbonization. South Korea intends to designate special zones for a just transition by the end of 2026, providing tailored assistance such as vocational training and incentives in regions affected by industrial restructuring. A proposed coal power transition roadmap for 2040, supported by legislation, is intended to help workers adjust as coal-fired plants close. This component recognizes that the transition will require employment and regional development measures alongside investment in clean technologies.
K-GX therefore links renewable energy expansion with industrial modernization, transport electrification, domestic technology production and climate finance. Its 2030 renewable energy target and 2028 tandem solar milestone provide near-term benchmarks within a broader 2035 programme. The key test will be implementation: whether planned funding mobilizes investment at the intended scale, grid expansion keeps pace with new generation, and industrial technologies achieve commercially viable emissions reductions. These outcomes will determine whether the strategy delivers both its climate objectives and its ambition to strengthen South Korea’s position in global green manufacturing.
