Three signals from the first week of September 2026

Amazon extends its inset marketplace to aviation fuel certificates: Travel and freight buyers can now source verified aviation reductions through the same channel as their other value-chain credits. Aggregated corporate demand is what gets fuel plants to a final investment decision.

A new study brackets the carbon tax level that actually works: CFOs gain a defensible band for internal carbon prices. Most jurisdictions still price below it, which is why voluntary insetting demand, not tax, is doing the marginal work in supply chains today.

Singapore and Laos sign a carbon credit implementation agreement: Buyers in Singapore gain a second ASEAN source of correspondingly adjusted credits. Developers in Laos gain a compliance-grade buyer, provided project quality clears the eligibility bar.
