South Korea has notified the WTO of a proposed amendment to its Corporate Average Energy Efficiency and Greenhouse Gas Emission Standards for light-duty vehicles — covering passenger cars, vans, and light trucks — with WTO member comments accepted until 13 September 2026.
What Happened
The Republic of Korea circulated WTO TBT notification G/TBT/N/KOR/1367 on 16 July 2026, announcing a draft amendment to the Public Notice on Corporate Average Energy Efficiency Standards and Greenhouse Gas Emission Standards for light-duty vehicles. The amendment updates the regulatory framework governing fleet-average fuel efficiency and CO₂ emission performance requirements, aligned with Korea’s broader climate objectives and internationally harmonized vehicle emission standards. The notification triggers a 60-day WTO comment period for trading partners.
What’s New
- Amendment covers passenger cars, vans, and light trucks under Korea’s corporate average fuel efficiency framework.
- Updates both energy efficiency (fuel economy) and greenhouse gas emission (CO₂/km) performance standards at the fleet-average level.
- Aims to tighten environmental performance benchmarks and align Korea’s vehicle standards with climate commitments.
- WTO TBT notification G/TBT/N/KOR/1367 — full draft text available via the WTO TBT portal.
Key Dates & Comment Window
G/TBT/N/KOR/1367 circulated to WTO members.
WTO members and industry stakeholders may submit comments to Korea.
Implementation timeline to follow after the comment period and domestic rulemaking.
Affected Industries
Automotive OEMs selling passenger cars, vans, and light trucks in South Korea; Tier 1 powertrain and emissions-system suppliers; importers of light-duty vehicles into the Korean market.
Who Is Affected
Any manufacturer or importer subject to South Korea’s corporate average fuel efficiency and GHG emission reporting and compliance framework for light-duty vehicles, including both domestic manufacturers and foreign OEMs selling into the Korean market.
Substances / Standards in Scope
Corporate average CO₂ emission performance (g/km) and energy efficiency (fuel consumption) standards for light-duty vehicle fleets — passenger cars, vans, and light trucks sold in South Korea.
What Companies Should Do
- Review the draft amendment text via the WTO TBT notification portal (G/TBT/N/KOR/1367).
- Assess whether proposed standard changes affect fleet-average compliance targets for your Korean sales mix.
- Prepare and submit technical comments to Korea’s notifying authority before 13 September 2026 if your compliance position is affected.
- Coordinate with Korean importer/distributor partners on compliance outlook and model-line planning.
This is a pre-rulemaking consultation window — the draft is not yet final, but the 13 September 2026 comment deadline is a firm opportunity to influence final standard levels and compliance timelines for light-duty vehicle GHG and fuel efficiency requirements in South Korea.
