Currently, the EU Taxonomy classifies nuclear power generation as an environmentally and climate-friendly 'green' economic activity. In turn, GS Energy secured exclusive business rights within the Korean Peninsula through an investment in NuScale Power, a company holding the most advanced SMR technology worldwide, in June 2021. NuScale Power received final approval for its SMR design from the U.S. Nuclear Regulatory Commission (NRC) in 2020 and is currently in the first-of-a-kind (FOAK) development phase with support from the U.S. Department of Energy. GS Energy is committed to expanding its clean energy portfolio and contributing to technological innovation, positioning technologies like SMRs as key players in achieving carbon neutrality.

In April 2022, GS Energy signed an MOU with NuScale Power, Doosan Enerbility, and Samsung C&T to jointly develop projects for the construction and operation of SMR power plants worldwide.
Additionally, in May 2023, GS Energy signed an MOU with Uljin gun to assess the feasibility of introducing NuScale SMRs within the Uljin Nuclear Hydrogen National Industrial Complex.
GS Energy is dedicated to providing stable and eco-friendly energy supplies.

In particular, regarding opportunity factors, GS Energy aims to pioneer new markets in four key areas for the upcoming 2050 carbon-neutral era: green power generation portfolio, clean hydrogen economy infrastructure, smart power solutions, and the circular resource ecosystem.
Additionally, GS Energy is actively taking proactive measures to address climate-related risks, with a focus on activities such as energy recovery from unused energy at major subsidiaries (GS Power, Incheon Comprehensive Energy), promoting energy efficiency equipment, considering the introduction of CCUS technology, and greenhouse gas emission reduction activities.
