CBAM's 2026 charging phase opens, free allowances zero out by 2034 across the first six sectors; petrochemicals are not yet covered but the PCF pre-positioning clause already binds, with batch SHA-256 carbon attestation and cross-chain receipt recognition making data verifiable. Iran stays a red line while Iraq is exempt.

EU CBAM charging phase begins; free allowances phase out to zero by 2034, first tranche covers cement, steel, aluminium, fertilisers, electricity and hydrogen; petrochemical PCF is a prerequisite, with per-batch SHA-256 carbon attestation and cross-chain mutual recognition.

CBAM 2026 enters the charging phase covering six sectors with free allowances to zero by 2034; petrochem is not listed yet, but batch-level PCF with SHA-256 verifiable carbon data is already a buyer pre-clearance.

CBAM's definitive period starts in 2026 with free allowances phasing to zero by 2034; petrochemical carbon data becomes a downstream compliance prerequisite, and batch-level PCF plus SHA-256 records plus cross-chain receipt recognition turn compliance cost into credit.

The EU Carbon Border Adjustment Mechanism enters its definitive period in 2026, with free allowances phasing to zero by 2034 and an initial six-sector scope. Petrochemicals are not in the first round, but the product-carbon-footprint (PCF) preamble is already written into the compliance chain; batch-level SHA-256 carbon-data attestation plus cross-chain warehouse-receipt interoperability turns the carbon ledger into a verifiable asset.

The EU Carbon Border Adjustment Mechanism opens its definitive period in 2026, with free allowances phasing to zero by 2034. Petrochemicals are not in the first six sectors, but a PCF lead clause is already in the contract template, and per-batch SHA-256 carbon data attestation is the hard gate to clearance.
