The European Commission will publish the first quarterly CBAM certificate price on April 7, 2026. The price equals average EU ETS auction costs for the preceding quarter. Importers must purchase certificates from February 2027 covering 2026 imports. Quarterly pricing applies only during 2026, transitioning to weekly from 2027. Subsequent quarterly publications occur June 6, October 5, and January 4, 2027. DG TAXUD seeks platform developer proposals until March 20, 2026. The mechanism provides transparent carbon pricing aligned with EU domestic industry costs.
